A nurse is caring for a 68-year-old patient diagnosed with influenza A who presents with high fever, severe body aches, and fatigue for the past 48 hours. Which nursing intervention should be the priority to address potential complications?
1Administer oseltamivir (Tamiflu) as prescribed within the first 48 hours of symptom onset✓ 정답
2Encourage increased fluid intake to prevent dehydration
3Implement strict isolation precautions to prevent transmission
4Provide comfort measures including rest and analgesics for body aches
해설
Oseltamivir is the priority as it must be given within 48 hours of symptom onset for optimal antiviral efficacy, especially in high-risk elderly patients. Other interventions like hydration and comfort measures are supportive but secondary.
Core Nursing ExplanationKey Concept Analysis: This question assesses the nurse's ability to prioritize interventions for a high-risk patient with influenza A. The core principle is time-sensitive pharmacological intervention. While all listed actions are appropriate for influenza care, the priority is determined by the patient's risk factors (age 68), the specific diagnosis (influenza A), and the critical therapeutic window for antiviral medication.
Answer Rationale: The correct answer is ① Administer oseltamivir (Tamiflu) as prescribed within the first 48 hours of symptom onset. Key Point! Oseltamivir is a neuraminidase inhibitor that works by preventing the release of new viral particles from infected cells. Its efficacy in reducing symptom severity, duration, and the risk of complications (like pneumonia) is maximized when initiated within 48 hours of symptom onset. This patient is 68 years old, placing them in a high-risk category for severe influenza complications. Therefore, administering this time-sensitive medication is the priority nursing action to directly address and mitigate potential complications.
Distractor Analysis:
Watch out for confusion! While ② Encourage increased fluid intake is a crucial supportive measure to prevent dehydration from fever, it is a general supportive care measure, not the most time-critical intervention specific to altering the disease course.
Watch out for confusion!③ Implement strict isolation precautions is essential for infection control and public health (using Droplet Precautions). However, the question asks for the priority to address "potential complications" for *this specific patient*. Preventing transmission protects others but does not directly reduce this patient's risk of medical complications like pneumonia.
Watch out for confusion!④ Provide comfort measures including rest and analgesics is important for symptom management and aligns with the nursing process. However, comfort measures, while vital for quality of care, are supportive and do not have the same urgent, disease-modifying potential as the antiviral medication within its narrow window.
Related Concepts: This integrates knowledge of pharmacology (antiviral mechanism and timing), infection control (influenza transmission), gerontological nursing (increased risk in older adults), and nursing prioritization (using frameworks like ABCs, Maslow, or acute vs. chronic). The principle is that a nursing action that directly prevents deterioration or treats the underlying cause takes priority over equally important but less urgent supportive measures.
Concept Summary
Concept
Key Points
Influenza A in Older Adults
High-risk group for severe disease and complications (e.g., bacterial pneumonia, exacerbation of CHF/COPD).
Oseltamivir (Tamiflu)
Neuraminidase inhibitor. Priority action: Administer within 48 hours of symptom onset for optimal effect.
Nursing Prioritization
Time-sensitive, disease-modifying interventions take precedence over routine supportive care.
Influenza Precautions
Droplet Precautions (mask, gown, gloves, eye protection if splash risk). Implement upon suspicion.
Supportive Care
Hydration, rest, antipyretics/analgesics (e.g., acetaminophen), and monitoring for complications.
Side-by-Side Comparison!
Intervention
Purpose/Rationale
Priority Level for *This* Question
Administer Oseltamivir
Direct antiviral action to shorten illness and prevent complications. Time-critical.
Highest Priority (Correct Answer)
Encourage Fluids
Supportive care to prevent dehydration from fever and maintain hydration status.
Important, but not time-critical for disease modification.
Strict Isolation
Infection control to prevent transmission to others (Droplet Precautions).
High priority for public health, but secondary for preventing *patient* complications.
Comfort Measures
Alleviate symptoms (pain, fever) and promote rest for healing.
Standard supportive care, lower priority than definitive treatment.
Anatomy, Physiology & Pharmacology Points
Pathophysiology: Influenza virus infects respiratory epithelial cells, causing cell damage and triggering a systemic inflammatory response (fever, myalgia, fatigue).
Pharmacology: Oseltamivir inhibits the viral neuraminidase enzyme, which is essential for the release of progeny virions from infected cells. This limits viral spread within the host.
Geriatric Consideration: Age-related decline in immune function (immunosenescence) increases susceptibility to severe infection and complications.
Memory Tips
Think "TAMIFLU = TIME": Tamiflu's effectiveness is tied to Time – must start within 48 hours.
Rule of "Treat First, Comfort Later": When a medication can change the disease outcome and has a strict deadline, it jumps to the front of the line.
High-Frequency NCLEX Topics
This question tests prioritization and pharmacological therapeutics, two of the most heavily tested areas on the NCLEX-RN. You will frequently see questions where multiple correct nursing actions are presented, and you must choose the one that is most urgent, most time-sensitive, or addresses the greatest risk to the patient. Always look for clues like "first," "priority," "initial," or, as in this case, a specific time frame ("within 48 hours").
Watch Out for Question Variations!
Shift in Focus: The same scenario could ask: "Which finding requires immediate notification to the provider?" – The answer might shift to signs of bacterial pneumonia (e.g., change in sputum, high fever returning after initial improvement).
Patient Education Focus: "What is the most important information to teach a patient prescribed oseltamivir?" – Answer: "Take it within 48 hours of symptoms starting and complete the full course."
Infection Control Focus: "Which precaution is required for this patient?" – Answer: Droplet Precautions.
Nursing Clinical Practice GuideClinical Scenario: You are the nurse on a medical-surgical unit. Mr. Johnson, a 68-year-old with a history of hypertension, is admitted with confirmed Influenza A. He has a fever of 102.5°F (39.2°C), severe myalgia, and is fatigued. His symptoms started approximately 36 hours ago.
Nursing Intervention Strategy:
Assessment: Perform a focused respiratory assessment (lung sounds, work of breathing, SpO2). Monitor vital signs frequently. Assess hydration status (skin turgor, mucous membranes, urine output).
Priority Action: Key Point! Verify the order for oseltamivir and administer it promptly. Confirm the timing of symptom onset with the patient/family to ensure it is within the 48-hour window.
Concurrent Interventions:
Initiate Droplet Precautions: Place patient in a private room or cohort with another influenza patient. Wear a surgical mask upon entry. Post signage.
Manage symptoms: Administer prescribed antipyretics/analgesics (e.g., acetaminophen). Provide a cool environment, light bedding.
Promote rest: Cluster care to minimize disturbances.
Monitoring for Complications: Be vigilant for signs of bacterial pneumonia (increased cough, purulent sputum, worsening fever, pleuritic chest pain, tachypnea, hypoxia).
Patient Safety and Precautions:
Medication: Oseltamivir can cause nausea/vomiting. Administer with food to improve tolerance.
Infection Control: Droplet Precautions remain for at least 5 days after illness onset (longer in immunocompromised). Perform hand hygiene meticulously.
High-Risk Monitoring: Older adults may not exhibit classic symptoms; watch for subtle changes like confusion (delirium), functional decline, or weakness, which could indicate decompensation.
Check: Verify the "5 Rights" (Right patient, medication, dose, route, time). Critically, confirm symptom onset was within the last 48 hours.
Preparation: Capsules are typically 75 mg. For oral suspension, shake well and measure dose accurately.
Administration: Give orally, with or without food (giving with food can reduce GI upset).
Education: Instruct patient to complete the entire prescribed course (usually twice daily for 5 days), even if symptoms improve.
Monitoring: Observe for side effects (nausea, vomiting, headache, rare neuropsychiatric events).
A Word from Your Senior Nurse
"In the real world, the clock is always ticking for conditions like stroke, sepsis, and yes, influenza in high-risk patients. Your critical thinking in recognizing that a 68-year-old with flu symptoms for 48 hours needs antiviral medication *now* is what makes you an excellent nurse. Never underestimate the power of a simple, timely medication to prevent a hospital stay from turning into an ICU admission. On the NCLEX and at the bedside, always ask yourself: 'What is the one thing I must do *right now* to keep this patient safe and improve their outcome?' That's the heart of nursing prioritization."
Oseltamivir — A neuraminidase inhibitor antiviral medication used to treat and prevent influenza A and B. It is most effective when started within 48 hours of symptom onset.
Droplet Precautions — Infection control precautions used for pathogens spread through large respiratory droplets (e.g., influenza, pertussis, meningitis). Requires a private room or cohorting, and donning a mask upon entry.
Immunosenescence — The gradual deterioration of the immune system associated with natural aging, leading to increased susceptibility to infections and reduced vaccine efficacy in older adults.
Neuraminidase Inhibitor — A class of antiviral drugs (including oseltamivir and zanamivir) that block the neuraminidase enzyme on the influenza virus, preventing the release of new viral particles from infected host cells.
Myalgia — Medical term for muscle pain or aching, a common systemic symptom of viral infections like influenza.
