Week 3: Gas Exchange and Bronchodilators

Introduction to Bronchodilators

Effective gas exchange begins with a careful respiratory assessment, which prioritizes nursing actions accordingly. This discussion will focus on the pharmacotherapeutic interventions associated with respiratory medications, specifically bronchodilators. Each class of respiratory medication can be prioritized based on its administration sequence—first, second, and so forth. These medications facilitate breathing by dilating airways, promoting the clearance of secretions, and reducing inflammation. Some respiratory medications act singularly, while others are combination products that utilize multiple drug actions.

Conditions Treated by Respiratory Medications

Respiratory medications are utilized to address a variety of conditions, including:

• Allergies and hay fever
• Chronic obstructive pulmonary disease (COPD)
• Asthma
• Emphysema
• Chronic bronchitis

Rescue Inhalers and Drug Classifications

The short-acting inhaled beta2-agonists are recommended for use as rescue inhalers rather than for daily maintenance to prevent shortness of breath. The primary classifications of respiratory drugs include bronchodilators, antihistamines, expectorants, antitussives, and decongestants.

Use of Respiratory Medications

Respiratory medications are crucial in managing a variety of disorders, such as allergies, asthma, COPD, emphysema, and chronic bronchitis. In emergencies, adrenergic drugs are used to enhance cardiac output and support effective respiration through bronchodilation.

Types of Bronchodilators

Bronchodilators can be categorized further based on their mechanisms and effects. Subjective and objective symptoms help determine the most suitable medication.

1. Antihistamines: These drugs constrict smooth muscle, reduce body secretions, and increase capillary permeability, making them effective for allergic rhinitis and anaphylaxis.
2. Decongestants: These are categorized into adrenergics, anticholinergics, and topical corticosteroids. They shrink swollen nasal mucous membranes and relieve nasal congestion.
3. Antitussives: These medications suppress the cough reflex by acting on the brain’s cough center.
4. Expectorants: They aid in the expulsion of mucus from the respiratory tract by thinning secretions.

Short-Acting Beta-Adrenergic Agonists (SABA)

Bronchodilators are essential for treating various respiratory conditions characterized by inflammation and bronchoconstriction. Short-acting beta-adrenergic agonists, such as albuterol, are indicated for immediate relief during asthma attacks. These medications work by relaxing and dilating smooth muscle in the bronchi and bronchioles, facilitating airflow and improving oxygenation.

Patient Scenario: Valine

For example, Valine, a 24-year-old nursing student newly diagnosed with asthma, experiences tightness in her chest and difficulty breathing after exertion. In this case, she should use her short-acting inhaled beta2-agonists for relief.

Long-Acting Beta2 Agonists (LABA)

Unlike SABAs, long-acting beta2 agonists are not intended for acute bronchoconstriction. They are prescribed for long-term maintenance therapy in conditions such as asthma and COPD and are typically taken twice daily. Common examples include salmeterol and formoterol, often used in conjunction with inhaled corticosteroids.

Anticholinergics

Ipratropium, the most widely used anticholinergic bronchodilator, is effective for preventing bronchospasm in patients with COPD, bronchitis, and emphysema. It works by blocking acetylcholine to facilitate bronchodilation.

Mechanism of Action

Acetylcholine plays a crucial role in bronchial smooth muscle contraction, which can be detrimental in obstructive lung diseases. Anticholinergic drugs like ipratropium block this neurotransmitter, thereby reducing airway constriction.

Adverse Effects

Common adverse reactions to anticholinergic medications include:

• Cough
• Nervousness
• Nausea
• Dry mouth (xerostomia)
• Headache

Serious reactions can include paradoxical bronchospasm and anaphylaxis.

Here’s a rephrased version of your content, organized into paragraphs and tables while maintaining APA formatting. I’ve included references at the end.

Drug Interactions with Ipratropium

Ipratropium is primarily used to treat chronic obstructive pulmonary disease (COPD), but it has some potential drug interactions that require caution. The only drug explicitly contraindicated with ipratropium is revefenacin, another inhaled medication used for COPD management. Certain conditions are associated with medications that can interact with ipratropium, including:

It is essential to avoid using any other anticholinergic medications or those metabolized through the CYP450 system alongside ipratropium to prevent adverse interactions.

Dosage Information

Ipratropium is available as a nebulized solution in a 0.02% concentration, containing 0.5 mg in a 2.5 mL vial. Below is a summary of its typical dosing and special considerations:

Patient Education

Proper education for patients using ipratropium is vital to ensure safe and effective use of the medication. The following points are critical:

The most critical points for patients regarding ipratropium inhalation include avoiding contact with the eyes (especially for those with glaucoma) and seeking medical attention if breathing problems worsen rapidly.

Albuterol: A Beta Agonist

Introduction to Albuterol

Albuterol is a short-acting beta-2 agonist (SABA) that acts as a bronchodilator, used primarily to treat bronchospasm in respiratory conditions like asthma and COPD. It can be administered orally or through inhalation, with inhalation being the preferred method due to faster onset and effectiveness.

Indications for Use

Albuterol is primarily indicated for conditions with reversible obstructive airway issues and is also effective for preventing exercise-induced bronchospasm. Beyond respiratory use, albuterol can be employed in other systems due to its mechanism of action, such as treating hypotension and shock.

Mechanism of Action

Albuterol targets beta-2 adrenergic receptors in the lungs, causing smooth muscle relaxation in the airways, thereby facilitating bronchodilation. It may also affect beta-2 receptors in the cardiovascular and nervous systems, leading to potential side effects.

Contraindications and Adverse Effects
Albuterol is contraindicated in patients with known allergies to the drug and those with cardiovascular conditions such as hypertension or arrhythmias. Common side effects include:

• Chest pain
• Rapid heartbeat
• Dizziness
• Nervousness
• Headaches

Dosing Guidelines for Albuterol

Albuterol is available in both oral and inhaled forms, with inhaled preparations offering quicker absorption and action. The typical maximum dosages are:

Proper technique during inhaler use is crucial to ensure medication effectiveness, and patients should rinse their mouths post-use to prevent dental issues.

Patient Education for Albuterol

Key educational points for albuterol include:

Understanding the pharmacological properties, indications, dosages, and patient education for ipratropium and albuterol is essential for effective treatment of respiratory conditions. Proper management of these medications can significantly enhance patient outcomes and ensure safety during therapy.

Theophylline: An Overview

Mechanism of Action and Drug Effects

Theophylline is primarily used for the prevention of acute asthma attacks and is not recommended as a rescue medication during an active attack. While the exact mechanism by which theophylline operates remains unclear, it is known to enhance cyclic adenosine monophosphate (cAMP) levels and act as an antagonist to adenosine receptors. Adenosine is crucial in cellular metabolism and ATP production, which serves as the energy source for all bodily cells. In simpler terms, theophylline can be likened to caffeine, as it is metabolized into caffeine in the body. Caffeine acts as a central nervous system (CNS) stimulant, particularly in the medulla, leading to an increased respiratory rate. At higher doses, caffeine can also stimulate the cardiovascular system, resulting in enhanced cardiac output by increasing the heart’s strength and rate. Additionally, theophylline can enhance kidney function by raising the glomerular filtration rate (GFR), resulting in a diuretic effect. Thus, one could consider theophylline as similar to an energy drink, where both caffeine and theophylline lead to increased energy levels and respiratory stimulation.

Contraindications

The only absolute contraindication for theophylline use is a known allergy to the medication. Caution is advised for patients with active peptic ulcers, seizure disorders, cardiovascular issues, pulmonary edema, liver impairment, hypothyroidism, sepsis, or shock, as the medications used for these conditions may interact with theophylline. Special care should also be taken when prescribing theophylline to neonates, infants, and the elderly.

Tobacco and Theophylline

One significant substance that affects theophylline levels is tobacco. Smoking alters the concentration of theophylline in the bloodstream, as it induces the metabolism of the drug via the CYP1A2 substrate, leading to a reduced pharmacological effect. Consequently, smokers may require higher doses of theophylline. Conversely, if a non-smoker begins smoking while on theophylline, they may experience a resurgence of asthma symptoms due to the drug’s decreased efficacy.

Adverse Effects

Given that theophylline is metabolized into caffeine, its side effects often resemble those of caffeine as a CNS stimulant. Understanding the relationship between the drug’s mechanism and its side effects helps clarify the expected physiological responses, making it easier to comprehend the medication’s use rather than memorizing isolated lists of drugs and their effects.

Drug Interactions

Theophylline is metabolized through the CYP450 system, making it susceptible to interactions with various medications and substances. Riociguat, a medication for pulmonary hypertension, is directly contraindicated with theophylline. Additionally, the herbal supplement St. John’s wort should be avoided. Changes in smoking habits during theophylline treatment are also discouraged. Notably, theophylline can lower the seizure threshold, requiring careful monitoring in patients taking phenytoin (Dilantin), which also undergoes CYP450 metabolism.

Dosages and Therapeutic Range

Theophylline is available in extended-release tablets ranging from 100 mg to 600 mg and an injectable solution of 80 mg per 15 mL. There are no specific dose adjustments required for patients with liver or kidney impairment. Theophylline has a narrow therapeutic window, and toxicity can arise from both overdose and slow metabolism. Regular laboratory monitoring of serum theophylline levels is essential to prevent toxicity. Acute toxicity may occur rapidly after a single large dose or several large doses, whereas chronic toxicity can develop more gradually, allowing the body some time to adapt. Gastrointestinal symptoms are generally associated with acute toxicity, while seizures and cardiovascular issues are more common in chronic overdose.

Patient Education

Patients should be informed about several important considerations when taking theophylline:

• Report any alcohol use or smoking history to your healthcare provider, especially if you have recently quit smoking.
• Notify your healthcare provider of any high fever lasting 24 hours or longer.
• Pregnant or breastfeeding women should consult their doctors before using theophylline.
• Theophylline should not be used as a rescue treatment during an asthma attack.
• Capsules should be swallowed whole; they should not be crushed or chewed.
• Patients should not take two doses simultaneously.
• Avoid sudden changes in smoking habits without consulting a healthcare provider, as dosage adjustments may be necessary.
• Patients should refrain from hazardous activities until they understand how theophylline affects them.
• Many medications and herbal supplements can affect theophylline levels, so inform your healthcare provider of all substances being taken.

Summary

Theophylline serves as a valuable medication for asthma management by preventing acute attacks, but it requires careful monitoring due to its narrow therapeutic range and potential interactions with other substances, particularly tobacco and specific medications. Understanding its pharmacological effects and mechanisms of action can enhance patient safety and treatment outcomes.

Preventive Medications in Asthma Management

Preventive medications are designed for ongoing management of asthma and should not be relied upon as rescue treatments. It is important to use these medications alongside other asthma therapies rather than as standalone treatments. Maintenance treatment with monoclonal antibody therapies (MAA) is recommended for patients suffering from severe asthma, where the effectiveness of these drugs varies based on the specific receptors they target. Common corticosteroids used for respiratory conditions include prednisone and methylprednisolone.

Non-Bronchodilator Medication Overview

Matching medications to their respective actions provides clarity on their roles in asthma treatment. For instance, Omalizumab selectively binds to immunoglobulin E (IgE), while Mepolizumab and Benralizumab function as interleukin-5 receptor antagonists for patients aged six and twelve years or older, respectively. One major benefit of inhaled corticosteroids over systemic corticosteroids is their localized action, which focuses more directly on the lungs.

Rinsing the Mouth: After using a glucocorticoid inhaler, rinsing the mouth is crucial to prevent oral candidiasis.

Inhaled Corticosteroids

Fluticasone is a commonly used inhaled corticosteroid for asthma prevention in both adults and children. The precise mechanism of fluticasone is not fully understood, but it is known to inhibit multiple inflammatory cytokines. It is contraindicated in patients with severe milk protein allergies. The recommended minimum age for fluticasone administration is two years.

Adverse Effects and Interactions: Common side effects of fluticasone include headache, hoarseness, and potential adrenal suppression. Medications such as desmopressin are contraindicated due to their interaction with fluticasone’s mineralocorticoid effects.

Montelukast and Leukotriene Receptor Antagonists

Montelukast functions as a leukotriene receptor antagonist (LTRA), effectively used for the prevention and treatment of asthma and allergic rhinitis. It is important to note that montelukast is not a rescue medication for acute attacks. LTRAs, such as montelukast, work by inhibiting the action of leukotrienes, which contribute to bronchoconstriction and inflammation.

Dosage Guidelines: Montelukast is available in various forms, including 10 mg non-chewable tablets, 4 mg, and 5 mg chewable tablets, with specific dosages recommended for adults and children.

Monitoring and Patient Education

When transitioning from systemic corticosteroids to inhaled corticosteroids, it is vital to monitor for signs of adrenal insufficiency, including fatigue, nausea, and hypotension. Patients should also be educated on the correct use of inhaled medications and the importance of dental hygiene to prevent complications such as oral thrush.

Key Points for Patient Education:

• Fluticasone is not a rescue medication.
• Rinse the mouth after use to prevent infections.
• Monitor for signs of adrenal insufficiency when switching corticosteroids.

Altered Oxygenation and Physical Activity

Altered oxygenation can be decreased and is often related to pathophysiological changes caused by respiratory diseases. Concurrently, patients may experience decreased physical activity due to disease-induced fatigue and low oxygen saturation levels. Additionally, self-actualization needs may decline because of reduced adherence to medication regimens and the resulting undesirable adverse effects.

Nursing Interventions and Patient Education

Nursing interventions aimed at supporting respiratory disease processes focus primarily on compliance, preventing exacerbations, and educating patients about their drug therapies. Key aspects of these interventions include:

Evaluation of Medication Effectiveness

The evaluation of respiratory medications is crucial in determining their efficacy. Indicators of successful treatment include:

Documentation Guidelines

Thorough documentation is a critical component of patient care. Essential details to record include:

Clinical Scenarios

1. A pediatric client with asthma receives omalizumab, and the guardian inquires about the medication and its prescription. The nurse should explain, “Omalizumab blocks allergic reactions that are common in asthma patients. Your child’s pediatrician prescribed it this morning, and it will be given alongside their other asthma medications.”

2. Before administering montelukast to a client post-surgery experiencing an asthma exacerbation, the nurse should assess for allergies to cellulose and lactose, as these contraindicate the medication.

3. It is crucial to match adverse effects to the appropriate drug classifications. Nursing diagnoses should align with supporting statements to create complete nursing diagnoses.

4. The nurse can assess understanding of respiratory management regimens if the patient demonstrates verbalized understanding of their therapeutic management, clear airway maintenance behaviors, and identification of potential complications.

5. Montelukast use necessitates monitoring of ALT and AST levels during therapy to assess liver function.

6. Goals for asthma treatment should include the absence or reduction of congestion, maintenance of airway patency, and identification of potential complications.

7. If a pediatric patient shows swelling of the tongue after receiving omalizumab, this may indicate a life-threatening side effect requiring immediate intervention.

Antihistamines Overview

Introduction

Antihistamines are drugs that compete with histamine for specific receptor sites, primarily H1 receptors, to alleviate allergy symptoms such as allergic rhinitis, hay fever, hives, itching, runny nose, and sneezing. They are often referred to as histamine antagonists, with common suffixes being -ine.

Considerations

It is essential to note that antihistamines cannot reverse histamine already bound to receptors. Administering these medications prior to exposure to allergens can help mitigate symptoms.

Adverse Effects

Drowsiness is the primary side effect of antihistamines, though non-sedating alternatives are available. Other adverse effects may include dry mouth, vision changes, difficulty urinating, and constipation.

Conclusion

In summary, understanding the pathophysiology of respiratory diseases, the role of antihistamines, and the importance of effective nursing interventions can significantly impact patient outcomes. Proper education and adherence to medication regimens are crucial in managing these conditions effectively.

This project focuses on Symproic, an oral opioid antagonist medication. Symproic is primarily prescribed to individuals suffering from Opioid Induced Constipation (OIC). As noted in the Journal for Managed Care and Formulary Management, “Opioid-induced constipation (OIC), new or worsening constipation occurring when initiating, changing, or increasing opioid use, represents the most common of these GI effects” (Hu & Bridgeman, 2018, p. 601). The target audience for our educational brochure includes adult patients diagnosed with chronic pain, which may stem from various conditions and who are receiving opioid analgesics for pain management. Research on Symproic’s safety and efficacy in children has not been conducted, thus our focus will remain on adult patients.

The brochure aims to creatively inform our audience about the complications associated with opioid use, as well as the adverse effects that can arise from these medications, highlighting the necessity of Symproic in their treatment regimen. In addition, it will detail how Symproic can alleviate some of the negative side effects associated with opioid use. Furthermore, we intend to educate patients about the therapeutic benefits of Symproic when prescribed appropriately. According to Markham (2017), “Symproic was associated with significantly greater improvements from baseline in the frequency of bowel movements per week compared with placebo (n = 620) at all assessed time points (weeks 12, 24, 36, and 52)” (p. 925).

Medication Teaching Plan: Xtampza ER Oxycodone

Introduction

The focus of this medical teaching plan brochure is Xtampza ER Oxycodone, a narcotic analgesic. Oxycodone is primarily intended for individuals experiencing pain. It functions by binding to opiate receptors in the central nervous system (CNS), altering both the perception and response to painful stimuli while inducing generalized CNS depression (Vallerand, Sanoski, & Quiring, 2019). The therapeutic goal of oxycodone is to reduce pain levels effectively. Pediatric patients may also be prescribed oxycodone at lower doses, specifically 0.05–0.15 mg/kg every 4–6 hours as needed (Vallerand, Sanoski, & Quiring, 2019). This brochure aims to inform users about the medication’s details, including drug classification, mechanism of action, administration and dosage guidelines, potential drug interactions, laboratory effects or interference, special considerations, adverse effects or toxicity, patient assessments, and essential patient education.

Patient Education

An essential component of patient education is to ensure that individuals are informed about the timing, route, and dosage of oxycodone. Without proper information, patients may encounter significant issues related to their medication. A primary concern regarding the use of oxycodone is its potential for abuse. It is crucial to advise patients about this risk, emphasizing that oxycodone has known abuse potential. Patients should be instructed to secure their medication from theft and never to share it with others. Additionally, oxycodone should be stored out of reach of children and in a location not easily accessible to others (Vallerand, Sanoski, & Quiring, 2019). Educating patients about drug abuse and how to prevent it is a vital aspect of patient teaching. Furthermore, the resource detailing Xtampza ER oxycodone capsules indicates that the medication may cause fetal harm and should be avoided during pregnancy.

Conclusion

In summary, the oxycodone brochure is designed to provide essential information in an accessible format for non-medical individuals. This resource is intended to equip patients and their families with the knowledge needed to use the medication safely and effectively. Ensuring that patients are well-informed about oxycodone’s properties and the importance of responsible use will contribute to improved patient outcomes and minimize the risk of abuse.

Anticoagulants and Related Medications

Therapeutic Monitoring and Drug Interactions

Regular lab monitoring is essential for patients on anticoagulants, particularly for prothrombin time (PT) and international normalized ratio (INR), where a therapeutic range of 2-3 is typically recommended. Thrombolytic drugs play a critical role in breaking down existing clots by activating the conversion of plasminogen to plasmin. These medications are utilized in various acute conditions, including myocardial infarction (MI), arterial thrombosis, deep vein thrombosis (DVT), occlusion of shunts or catheters, pulmonary embolism, and acute ischemic stroke.

Contraindications and Adverse Effects

The use of thrombolytic drugs comes with significant risks, including internal, intracranial, and superficial bleeding. Other potential adverse effects include hypersensitivity reactions, nausea, vomiting, hypotension, and cardiac dysrhythmias. Concurrent use with other anticoagulants or antiplatelet agents can increase the risk of bleeding. Patients should be advised against alcohol consumption while taking medications like disulfiram, as this can lead to unpleasant reactions such as flushing, rapid heartbeats, and low blood pressure.

Medication-Specific Considerations

Bronchodilators

Bronchodilators like albuterol and salmeterol are indicated for the management of asthma and chronic obstructive pulmonary disease (COPD). They are effective in preventing bronchospasm and alleviating symptoms associated with respiratory conditions. However, patients should be cautioned about the potential for paradoxical bronchospasm and the importance of not relying solely on these medications for immediate relief of acute symptoms.

Uric Acid Reducers

Allopurinol is primarily used for managing gout and preventing kidney stones. It is contraindicated in patients with severe kidney impairment and may cause side effects such as gastrointestinal disturbances and drowsiness. Patients should be informed about possible interactions with other medications, particularly those that affect uric acid levels.

Patient Education and Monitoring

Patient education is critical in ensuring the safe use of these medications. It includes monitoring for therapeutic and adverse effects, understanding drug interactions, and adhering to prescribed regimens. For instance, patients on anticoagulants should be educated about the significance of INR monitoring and the signs of bleeding. Additionally, patients taking disulfiram should be thoroughly informed about the dangers of alcohol consumption.

Conclusion

Overall, the management of conditions requiring anticoagulants, bronchodilators, and other related medications involves careful monitoring and patient education to optimize therapeutic outcomes while minimizing risks.

Pharmacology Exam 1: 

1. Medication Errors and Six Rights of Medication Administration (Chapter 1)

When reviewing medication errors, it is essential to focus on the six rights of medication administration:

• Right Drug: Ensure the correct drug is administered to the patient.
• Right Dose: Verify that the dosage is appropriate for the patient’s age and size.
• Right Time: Confirm the frequency of administration, the specific time for each dose, and the time of the last dose.
• Right Route: Do not assume the route of administration; always check the medication order and review any patient allergies.
• Right Patient: Use two identifiers (e.g., full name and date of birth) to verify the patient’s identity.
• Right Documentation: Accurately document all actions and report any observations.

Medication errors refer to any preventable event that may result in inappropriate medication use or patient harm.

2. Nursing Process (Chapter 1)

The nursing process is an essential framework for nursing practice, consisting of five critical steps:

• Assessment: The collection of patient data, including a comprehensive medication profile.
• Diagnosis: Identifying patient needs based on assessment findings.
• Planning: Establishing goals and desired outcomes for patient care.
• Implementation: Carrying out specific nursing actions to meet patient goals.
• Evaluation: Ongoing assessment at each stage to determine the progress toward meeting patient goals.

3. Objective and Subjective Data

When gathering patient information, nurses must distinguish between two types of data:

• Subjective Data: Patient-reported symptoms such as pain, nausea, and vomiting.
• Objective Data: Observable and measurable signs, such as blood pressure readings.

4. Routes of Medication Administration: Advantages and Disadvantages (Chapter 2)

5. Pharmacokinetics (Chapter 2)

Pharmacokinetics involves four key processes that affect drug activity in the body:

• Absorption: The drug moves from the administration site into the bloodstream.
• Distribution: The drug is transported by the bloodstream to the target tissues.
• Metabolism: Biotransformation of the drug, primarily occurring in the liver.
• Excretion: Elimination of the drug, mostly through urine and feces, but also biliary excretion.

6. Pediatric Considerations for Drug Administration (Chapter 3)

Pediatric patients exhibit several physiological differences that impact drug absorption and metabolism:

• Intramuscular absorption is often faster and irregular.
• Children have a higher total body water content but less fat.
• Liver, blood-brain barrier, and kidneys are immature, resulting in altered drug metabolism and excretion.

7. Drug Classifications: Schedule C-1 to C-5 (Chapter 4)

Medications are classified into five schedules based on their potential for abuse and medical use:

• C-1: High potential for abuse, no accepted medical use (e.g., heroin).
• C-2 to C-5: Decreasing potential for abuse and increasing accepted medical applications.

8. Telephone Orders (Chapter 1)

Telephone orders must be handled carefully in clinical settings:

• The prescriber must sign the verbal or telephone order within 24 hours.
• These orders are typically used in emergencies or time-sensitive situations.
• Abbreviations should not be used to avoid confusion.

9. Erickson’s Stages of Development

A thorough understanding of Erickson’s stages of development is crucial for providing age-appropriate care across the lifespan.

10. Over-the-Counter (OTC) Medications: Advantages and Disadvantages (Chapter 7)

11. Medication Use Terms (Chapter 2 and 38)

• Empiric: Administering treatment before obtaining specific diagnostic information.
• Definitive: First clinical intervention targeting a diagnosed condition.
• Prophylactic: Preventive treatment during planned events.
• Palliative: Focuses on symptom relief and comfort care.
• Maintenance: Prevents the progression of chronic illnesses, such as hypertension.

12. Synergistic Effect (Chapter 2)

A synergistic effect occurs when the combined effects of two drugs exceed the sum of their individual effects.

13. Vancomycin (Chapter 39)

Vancomycin is a bactericidal antibiotic used to treat methicillin-resistant Staphylococcus aureus (MRSA) and other gram-positive bacterial infections. It has poor oral absorption, so it is often administered intravenously. Peak levels range from 18 to 50 mcg/mL, with trough levels between 10 and 20 mcg/mL.

14. Antiviral Drugs (Chapter 40)

Antiviral medications suppress viruses by inhibiting replication or destroying virions. They are most effective in immunocompetent patients, often in conjunction with the body’s immune response.

15. Ciprofloxacin (Cipro) (Chapter 39)

Quiz One

Rights of Medication Administration

The five essential rights of medication administration are critical for ensuring patient safety. These include administering the medication to the right patient, giving the right dose, through the right route, and respecting the patient’s right to refuse. It is essential that the final check before administering the medication is done at the patient’s bedside, rather than at the nurse’s station, to ensure the medication is being given to the correct individual.

First Pass Effect

The first pass effect pertains to the way certain medications are metabolized by the liver. When oral medications pass through the liver, the amount of the drug available for use in the body decreases. This necessitates administering a higher dose for medications that undergo the first pass effect, such as oral morphine. Because of this process, less of the medication is absorbed into the bloodstream, making higher doses necessary to achieve therapeutic effects.

Nursing Considerations When Administering Medications

Nurses must follow specific protocols when administering medications. They should always verify the patient’s identity using two methods and never leave unused medication at the patient’s bedside. If a patient refuses medication, the nurse should dispose of it properly and document the refusal. The nurse should also stay with the patient until the medication is fully administered. Additionally, the nurse should be cautious of certain liquids, such as milk, which may impact medication absorption.

Routes of Medication Administration

Medications can be administered through various routes such as oral, subcutaneous, or transfer methods. When receiving an order that includes multiple routes, nurses should not assume the route but must verify with the healthcare provider and discontinue the other routes not used.

Ethical Considerations in Medication Administration

Patients have the right to refuse medication. There may be instances where a patient requests additional pain medication due to discomfort. While it is important to provide comfort, nurses must adhere to the code of ethics and follow appropriate guidelines for specific medications.

STAT and PRN Medications

Stat medications must be administered within 30 to 60 minutes, while PRN (as needed) medications are given only when necessary based on the patient’s condition.

Oral Medication Routes

Oral medications come in different forms, each with specific considerations. Capsules have a coating that breaks down to release the medication. Enteric-coated tablets prevent breakdown in the stomach and reduce gastrointestinal distress; crushing these tablets compromises the protective coating. Extended-release tablets should not be crushed, as this will release the medication all at once, potentially leading to adverse effects. Liquids, solutions, and suspensions are absorbed more quickly compared to tablets or capsules.

Pregnancy Categories

Medications are categorized according to their potential risks to the fetus:

• Category A: No risk to fetus or breastfeeding mothers.
• Category B: No risk to animal fetuses, but insufficient human data.
• Category C: No human studies available, but some animal research has been conducted.
• Category D: Potential fetal risk in humans has been reported.
• Category X: The risks outweigh the benefits.

Administration in Adults and Children

Infants have a higher concentration of water in their bodies compared to adults, which can affect how medications are distributed and metabolized.

Quiz Two

Antidote for Opioids

Naloxone is the antidote used for someone withdrawing from opioids.

Vasopressin for Diabetes Insipidus

In patients with diabetes insipidus, vasopressin impacts urine output. The common symptoms include polyuria (excessive urine), polydipsia (excessive thirst), and polyphagia (excessive hunger).

Patient Teaching: Levothyroxine

Levothyroxine is prescribed for hypothyroidism. It is important to swallow capsules whole without chewing or crushing them. The medication should be taken on an empty stomach, with a full glass of water, and at least 30 minutes before breakfast. Common side effects include heat intolerance, a fast heart rate, and diarrhea. More serious side effects include tremors and mood changes.

Propylthiouracil (PTU)

Propylthiouracil (PTU) can cause severe liver damage. Side effects include hair loss, difficulty tasting food, numbness or tingling of the hands or feet, joint or muscle pain, dizziness, and swelling of the neck.

Metformin for Diabetes

Metformin should be taken with meals to reduce gastrointestinal side effects. The extended-release tablets should not be crushed or chewed. Metformin must be stopped 48 hours before any procedures that involve contrast dye, to avoid the risk of lactic acidosis.

Regular Insulin and Meal Timing

Patients should eat within 30 to 60 minutes after taking regular insulin to avoid hypoglycemia. For those on NPH insulin, it is important to time exercise appropriately to avoid low blood sugar.

Prednisone – Steroids

Side effects of prednisone include dizziness, insomnia, mood swings, and increased appetite. To counteract bone density loss, patients should increase their intake of calcium and vitamin D.

Glaucoma Medications

When administering Timolol or Pilocarpine for glaucoma, it is important to follow proper eye drop techniques to ensure the medication is absorbed effectively.

Quiz Three

Antihistamines

Antihistamines can cause side effects such as blurry vision, dizziness, and drowsiness. They are often prescribed for colds due to their anticholinergic effects, which dry up secretions.

Respiratory Medications

Oral respiratory medications have a longer systemic effect, while nasal sprays provide immediate relief but may cause rebound congestion with overuse.

Antitussive and Expectorant Medications

Antitussives suppress the cough reflex, while expectorants thin mucus, making it easier to clear from the airway.

Albuterol

Common side effects of albuterol include feeling shaky, headaches, and nasal irritation. Inhaled steroids may cause thrush, so patients should rinse their mouths after use.

Decongestants and Theophylline

Decongestants help with breathing, while theophylline is used for COPD patients. Side effects of theophylline include palpitations and tachycardia.

Signs, Symptoms, and Causes of Skin Disorders

Impetigo:

Impetigo is a prevalent infection mainly affecting infants and children, caused by the highly contagious bacteria Staphylococcus aureus, particularly in newborns. Its key signs include quickly expanding lesions on the face that eventually burst, forming crusty scabs.

Psoriasis:

Psoriasis is a chronic inflammatory skin condition marked by the abnormal activation of T cells and excessive keratinocyte production. It is non-contagious and typically appears as silvery plaques on areas like the face, scalp, elbows, and knees, often accompanied by itching or a burning sensation.

Herpes Simplex Virus Type 1:

The Herpes Simplex 1 virus is the leading cause of cold sores or fever blisters, usually near the lips. It spreads through saliva, primarily via direct contact. Symptoms include pain, sore lips, a burning sensation, tingling, itching, and the formation of fluid-filled blisters.

Nevi:

Nevi are darkly pigmented skin lesions, commonly known as moles or birthmarks. While most nevi are benign, some may be cancerous. It’s crucial to monitor these lesions for any changes that could indicate malignancy.

Varicella (Chickenpox):

Varicella, or chickenpox, is a highly contagious viral infection primarily affecting children. It is characterized by an itchy blister-like rash, along with symptoms such as fever, fatigue, and loss of appetite.

Zoster (Shingles):

Zoster, commonly referred to as shingles, is caused by the reactivation of the varicella-zoster virus in adults who have previously had chickenpox. It presents as a painful rash that forms a stripe of blisters, typically affecting one side of the body, often on the trunk.

Pemphigus:

Pemphigus is an autoimmune disorder impacting the mucous membranes of the mouth and genitals. Autoantibodies disrupt the cohesion between epidermal cells, leading to blistering, skin shedding, and increased risk of secondary infections.

Urticaria (Chronic Hives):

Urticaria, or chronic hives, is a type 1 hypersensitivity reaction triggered by certain substances or medications. It is characterized by intensely itchy, red, swollen welts on the skin, which may also cause itching in the throat, eyes, and lips.

Secondary Infections:

Secondary infections arise when opportunistic pathogens exploit a weakened immune system following a primary infection. Common examples include vaginal yeast infections following antibiotic use or bacterial pneumonia after a viral upper respiratory infection.

Candidiasis:

Candidiasis is a yeast infection caused by Candida albicans, often affecting mucous membranes or the skin, resulting in intense itching, inflammation, and a thick, white discharge.

Tinea Capitis:

Tinea capitis is a scalp infection that can be transmitted by cats and dogs. It presents with swollen, raised red rings, severe itching, dandruff, and bald patches on the scalp.

Skin Cancers:

Seborrheic keratosis is a benign skin condition characterized by the proliferation of basal cells, typically found on the face or upper trunk. Actinic keratosis refers to pigmented, scaly patches that can develop into skin cancer.

NR 293 Skin and Skin Disorders

Conclusion

In summary, skin disorders like impetigo, psoriasis, herpes simplex 1, nevi, varicella, zoster, pemphigus, urticaria, candidiasis, and tinea capitis each have distinct causes and symptoms. Understanding these conditions is crucial for accurate diagnosis and treatment. Additionally, skin cancers such as seborrheic keratosis, actinic keratosis, squamous cell carcinoma, malignant melanoma, and papule-nevus necessitate careful monitoring due to their potential malignancy.

Gastrointestinal Conditions: Causes, Signs, and Symptoms

Hiatal Hernia:

This condition occurs when the upper part of the stomach protrudes through the diaphragm. Contributing factors include a short esophagus, trauma, or weakened muscles. Common symptoms are heartburn, belching, discomfort while lying down, and pain behind the breastbone.

Chronic Gastritis:

This inflammation of the stomach lining can result from microorganisms, allergies, alcohol use, and other factors. It is often linked to Helicobacter pylori infections, NSAID use, and excessive alcohol intake. Symptoms may include loss of appetite, nausea, vomiting (including blood), and abdominal pain.

Peptic Ulcer Disease:

This involves the formation of ulcers in the esophagus, stomach, or duodenum, primarily caused by Helicobacter pylori infection, NSAID use, or Zollinger-Ellison Syndrome. Symptoms typically include pain, nausea, vomiting, and weight loss.

Cholelithiasis:

The formation of gallstones in the gallbladder can occur due to obstruction, a high-fat diet, certain medications, age, or ethnicity. Symptoms can be absent, but high levels of cholesterol or bilirubin may lead to gallstone development.

Hepatitis:

This refers to liver inflammation and includes types A, B, and C, each with different transmission methods and symptoms. The disease progresses through stages: prodromal, jaundice (yellowing of skin and eyes), and recovery.

Hepatic Encephalopathy:

This condition results from liver damage and leads to a decline in brain function. Symptoms can include forgetfulness, a musty breath odor, hand tremors, and slurred speech, with diagnosis typically made through blood tests.

NR 293 Final Exam Concept Review Pathophysiology

Cirrhosis:

A progressive and irreversible liver disease primarily caused by excessive alcohol consumption and hepatitis. Symptoms include liver inflammation, scar tissue formation, fatigue, loss of appetite, ascites (fluid accumulation in the abdomen), jaundice, and complications like infections and esophageal varices.

Esophageal Varices:

These are enlarged veins in the lower esophagus caused by obstructed blood flow from the liver. They may not present symptoms initially but can lead to bleeding and shock. Complications include liver failure and other serious conditions.

Crohn’s Disease:

A chronic inflammatory bowel disease that can affect any part of the digestive tract, marked by the presence of ulcers. Symptoms include non-bloody diarrhea, abdominal pain, malabsorption, and weight loss.

Ulcerative Colitis:

This inflammatory bowel disease mainly affects the colon and rectum, starting at the rectum and progressing upward. Symptoms include abdominal pain, bloody diarrhea, tenesmus (a constant urge to have a bowel movement), and fever.

Appendicitis:

This is the inflammation of the appendix, often due to obstruction, infection, or ischemia (reduced blood supply). Symptoms include pain in the upper abdomen and right lower quadrant, tenderness, and fever, typically requiring prompt medical attention and surgical removal of the inflamed appendix.

Intestinal Obstruction:

This condition involves a blockage in the intestines, leading to crampy abdominal pain, vomiting, and abdominal swelling. Causes can include constipation and previous surgeries.
