A 6-year-old child is brought to the pediatric clinic with a 2-day history of fever and the appearance of small, fluid-filled vesicles on the trunk and face. The parent reports that the child has been scratching the lesions frequently. What is the most important assessment the nurse should perform first?
1Measure the child's temperature and assess for signs of dehydration
2Examine the lesions for signs of bacterial superinfection
3Assess the child's respiratory status and auscultate lung sounds✓ 정답
4Evaluate the child's pain level using an age-appropriate pain scale
해설
The priority assessment is respiratory status due to the risk of varicella pneumonia, a life-threatening complication. Other options address fever, superinfection, or pain, which are secondary concerns.
Core Nursing ExplanationKey Concept Analysis: This question assesses the nurse's ability to prioritize assessments based on the most life-threatening complication associated with a common childhood illness. The clinical presentation—fever and fluid-filled vesicles on the trunk and face—is classic for Varicella (Chickenpox). While the illness is often self-limiting, it can lead to serious complications, especially in certain populations. The nurse must apply the ABC (Airway, Breathing, Circulation) priority framework to identify the most urgent assessment.
Answer Rationale: Key Point! The correct answer is to assess respiratory status first. The most severe and potentially fatal complication of varicella in children is Varicella Pneumonia. It can develop rapidly, even in otherwise healthy children, and is a leading cause of varicella-related mortality. Respiratory distress would be a late sign; early assessment of lung sounds and respiratory effort is crucial for early detection and intervention. This aligns with the primary nursing responsibility of ensuring patient safety by addressing threats to airway and breathing first.
Distractor Analysis:
Watch out for confusion! Option ① (Measure temperature and assess for dehydration) addresses common and expected symptoms of varicella (fever, potential fluid loss). While important, it is not the priority when a life-threatening complication like pneumonia is a risk. Dehydration is managed after ensuring the airway and breathing are stable.
Option ② (Examine lesions for superinfection) is a relevant nursing action because scratching can lead to Secondary bacterial infection (e.g., with Staphylococcus or Streptococcus). However, a localized skin infection, while requiring treatment, does not pose an immediate threat to life like respiratory failure does.
Option ④ (Evaluate pain level) is important for comfort and comprehensive care, as the lesions can be very pruritic (itchy) and painful. Pain management is a key part of nursing care but, again, is secondary to physiological stability (ABCs).
Related Concepts: The NCLEX frequently tests the nurse's ability to triage and prioritize. Always consider the Maslow's Hierarchy of Needs and the ABCs. Physiological needs (airway, breathing) always come before safety, comfort, or teaching needs. For infectious diseases, know the most dangerous complication (e.g., pneumonia for varicella, airway obstruction for epiglottitis, encephalitis for measles).
Concept Summary
Concept
Key Points
Varicella (Chickenpox)
Highly contagious viral infection (Varicella-Zoster Virus). Presents with fever, malaise, and a characteristic rash that progresses from macules → papules → vesicles → crusts.
Priority Assessment (ABCs)
Airway, Breathing, Circulation. The foundation of nursing assessment and intervention. Any threat to these is the #1 priority.
Varicella Pneumonia
The most serious complication. Risk increases with age, smoking, pregnancy, and immunodeficiency. Symptoms include cough, dyspnea, tachypnea, crackles on auscultation.
Secondary Bacterial Infection
A common complication from scratching vesicles. Presents with increased redness, warmth, swelling, purulent drainage. Managed with antibiotics.
Side-by-Side Comparison!
Complication of Varicella
Clinical Manifestations
Nursing Priority
Varicella Pneumonia (Most Serious)
Cough, shortness of breath, tachypnea, fever, hypoxemia, crackles/rales.
AIRWAY & BREATHING. Assess respiratory status, administer O2, prepare for possible hospitalization.
Bacterial Skin Superinfection (Most Common)
Lesions become more erythematous, swollen, warm, with purulent exudate; fever may spike.
INFECTION CONTROL & SKIN INTEGRITY. Culture drainage, administer antibiotics, promote hygiene, trim nails.
Encephalitis (Neurological)
Headache, vomiting, confusion, seizures, altered level of consciousness.
Pathophysiology: The Varicella-Zoster Virus (VZV) is inhaled, replicates in the respiratory tract, spreads via blood (viremia) to the skin, causing the vesicular rash. In pneumonia, the virus infects the lung parenchyma, causing inflammation and impaired gas exchange.
Drug Therapy:Acyclovir is an antiviral used for severe cases or high-risk patients. It inhibits viral DNA replication. It is most effective if started early in the course of the illness.
Prevention: The Varicella Vaccine is a live attenuated vaccine given in two doses (12-15 months and 4-6 years). It has dramatically reduced the incidence of chickenpox and its complications.
Memory Tips
Pneumonia is Priority for Pox: Remember the alliteration. For Chickenpox, Pneumonia is the Priority complication.
ABCs Always Beat Itch: Airway and Breathing Come before Scratching. This helps prioritize respiratory assessment over managing pruritus (itching).
Vesicles on Trunk + Face = Think Varicella: The classic centripetal distribution (more on trunk/face than extremities) is a hallmark.
High-Frequency NCLEX Topics
This scenario tests prioritization and complication recognition, two of the most heavily tested skills on the NCLEX-RN. You will often be given a patient with a common condition and multiple potential problems; you must choose the action that addresses the greatest threat to life or physiological stability first (ABCs, Maslow's).
Watch Out for Question Variations!
Shift from Assessment to Intervention: "The nurse auscultates crackles in the lung bases of a child with varicella. What is the priority nursing intervention?" (Answer: Administer oxygen as prescribed and prepare for possible transfer to a higher level of care).
Shift to Patient Education: "A parent calls the clinic about their child's new chickenpox rash. What is the most important instruction the nurse should give?" (Answer: "Return immediately if your child develops a cough or has trouble breathing," focusing on recognizing the serious complication).
Shift to Infection Control: "A child with varicella is admitted to a pediatric unit. What type of isolation precautions should the nurse initiate?" (Answer: Airborne and Contact Precautions).
Nursing Clinical Practice GuideClinical Scenario: You are a nurse in a busy pediatric clinic. Mrs. Jones brings in her 6-year-old son, Liam, who has a fever of 101.5°F (38.6°C) and a rash that started on his chest yesterday and has now spread to his face. You see multiple small vesicles in various stages (some clear, some cloudy) on an erythematous base. Liam is sitting quietly but seems a bit lethargic.
Nursing Intervention Strategy:
Immediate Priority Assessment (ABCs): Before even taking a full history, quickly observe Liam's work of breathing. Is he using accessory muscles? Is his respiratory rate elevated for his age (>30-40 breaths/min)? Listen to his lung sounds in a quiet area. The presence of crackles, wheezes, or diminished breath sounds would be a red flag.
Comprehensive Assessment: After confirming stable respirations, proceed with a full assessment: vital signs (including O2 saturation), hydration status (skin turgor, mucous membranes, urine output), characteristics of the rash (stage, distribution, signs of infection), and pain/itch level.
Nursing Care & Education: Implement measures to prevent superinfection and promote comfort: encourage cool baths with colloidal oatmeal, apply calamine lotion, keep nails trimmed and clean, administer antipyretics (acetaminophen/ibuprofen) for fever and discomfort Key Point! (Avoid aspirin due to the risk of Reye's syndrome). Educate the parent on signs of complications to report immediately: difficulty breathing, persistent high fever, extreme lethargy, stiff neck, or lesions that look infected.
Patient Safety and Precautions:
Isolation: In a healthcare setting, place the child in a negative pressure room if available and use Airborne and Contact Precautions. The child is contagious from 1-2 days before the rash appears until all lesions have crusted over.
High-Risk Contacts: Identify if there are any pregnant women, newborns, or immunocompromised individuals in the household or who have been exposed. They are at risk for severe disease and may need post-exposure prophylaxis (Varicella-Zoster Immune Globulin - VZIG).
Nursing Procedure & Medication FlowProcedure for Respiratory Assessment in a Child:
Observe from the doorway: note color, posture, work of breathing, nasal flaring, retractions.
Count respirations for a full minute when the child is calm (best done by pretending to count the pulse).
Auscultate anterior and posterior lung fields, comparing side to side.
Obtain pulse oximetry reading.
Medication Administration:
Acyclovir (Antiviral): Often given orally. Emphasize the importance of completing the full course. Monitor for side effects like nausea, vomiting, and headache. IV acyclovir is used for severe cases; monitor renal function (BUN/Creatinine) as it can be nephrotoxic; ensure adequate hydration during infusion.
Antipyretics/Analgesics: Calculate dose based on weight (mg/kg). Use proper measuring device. Educate on alternating acetaminophen and ibuprofen if needed, keeping a log to avoid overdose.
A Word from Your Senior Nurse
"In the clinic or hospital, a child with chickenpox might seem routine, but never let your guard down. That subtle increase in respiratory rate or that faint crackle you hear at the lung base could be the only early warning sign of pneumonia. Your keen assessment skills are the first line of defense. On the NCLEX, they are testing this clinical judgment—can you see past the obvious (the itchy rash) to the potentially deadly (the silent pneumonia)? Always ask yourself: 'What is the worst thing that could happen to this patient right now?' and assess for that first. That mindset saves lives and will help you ace those priority questions!"
Varicella — A highly contagious viral infection caused by the Varicella-Zoster Virus (VZV), characterized by a febrile prodrome followed by a generalized, pruritic vesicular rash.
Varicella Pneumonia — The most serious complication of varicella, involving viral infection of the lung parenchyma, which can lead to respiratory failure and is a leading cause of varicella-related mortality.
ABC Priority Framework — A fundamental nursing and emergency care principle: Airway, Breathing, and Circulation are the top priorities in any patient assessment or intervention.
Secondary Bacterial Infection — A common complication of varicella where scratching the vesicles introduces bacteria (often Staphylococcus or Streptococcus), leading to localized skin infections like impetigo or cellulitis.
Airborne and Contact Precautions — Infection control measures required for varicella. Airborne Precautions require a negative pressure room and an N95 respirator for caregivers due to droplet nuclei. Contact Precautions require gown and gloves due to direct contact with lesions.
