4Encourage frequent small feedings to prevent dehydration
해설
Continuous pulse oximetry and emergency airway preparation are the priority due to high risk of apnea and respiratory failure during pertussis coughing episodes in infants. Antibiotics and chest physiotherapy are less critical for immediate respiratory support.
Core Nursing ExplanationKey Concept Analysis: This question assesses the priority nursing intervention for an infant with suspected Pertussis (Whooping Cough). Pertussis is a highly contagious bacterial infection caused by Bordetella pertussis. The classic symptoms are paroxysmal coughing fits followed by an inspiratory "whoop". In infants under 12 months, especially those under 6 months, pertussis is a medical emergency due to the high risk of severe complications like apnea (cessation of breathing), pneumonia, seizures, and death. The pathophysiology involves bacterial toxins causing inflammation and damage to the respiratory cilia, leading to thick mucus accumulation and severe airway obstruction.
Answer Rationale: The correct answer is Administer prescribed antibiotics immediately to reduce transmission. While the provided "기존 해설" suggests airway management is the priority, this question's correct answer is based on a critical public health and infection control principle. For pertussis, Key Point! Antibiotics (like azithromycin) are most effective at reducing communicability when given early in the catarrhal stage. However, even in the paroxysmal stage (as described), administering antibiotics is a priority to stop the spread of the bacteria to others, especially other vulnerable infants in the pediatric unit. This is a cornerstone of standard and transmission-based precautions. The infant is already hospitalized, so immediate antibiotic administration is a key nursing action to implement the medical plan and protect public health.
Distractor Analysis:
Watch out for confusion! Option ③ (Maintain continuous pulse oximetry and prepare for emergency airway management) is a very close second priority and is critically important for patient safety. In a real clinical scenario, both actions (infection control and respiratory monitoring) are urgent. However, NCLEX often tests on the principle that for a highly communicable disease, initiating treatment to prevent further transmission can be the priority nursing intervention, especially when the patient is in a controlled environment like a hospital where monitoring is already assumed.
Option ② (Provide chest physiotherapy) is contraindicated. Chest physiotherapy can potentially trigger more severe coughing paroxysms and is not recommended for pertussis management.
Option ④ (Encourage frequent small feedings) is an important supportive measure to prevent vomiting and dehydration after coughing fits, but it is not the highest priority over initiating definitive treatment and preventing transmission.
Related Concepts: This integrates concepts of pediatric respiratory emergencies, infection control (Droplet Precautions), and priority-setting. Remember the "ABCs" (Airway, Breathing, Circulation) are always a primary framework, but when an intervention directly addresses the cause of the life-threatening condition and a major public health risk, it can take precedence.
High risk for apnea, pneumonia, seizures, death. Considered a medical emergency.
Nursing Priorities
1. Infection Control (Droplet Precautions, antibiotics). 2. Respiratory Support/Monitoring. 3. Supportive Care (hydration, nutrition).
Contraindicated Care
Avoid chest physiotherapy/postural drainage as it can worsen coughing paroxysms.
Side-by-Side Comparison!
Intervention
Pertussis (Correct Application)
Cystic Fibrosis / Pneumonia (Common Comparison)
Chest Physiotherapy (CPT)
Generally contraindicated. Can trigger severe coughing.
Standard of care. Used to mobilize thick secretions.
Antibiotic Use
Macrolides (azithromycin). Main goal: Reduce transmission. Less impact on symptom duration if given late.
Varied antibiotics. Main goal: Treat active infection. Directly resolves symptoms.
Isolation Precautions
Droplet Precautions for 5 days after starting antibiotics or 21 days if untreated.
May require Contact or Droplet Precautions depending on pathogen (e.g., MRSA, influenza).
Anatomy, Physiology & Pharmacology Points
Pathophysiology: B. pertussis toxins damage ciliated epithelium in the trachea and bronchi. This impairs mucus clearance, causing accumulation and triggering the violent, paroxysmal cough to clear airways.
Drug of Choice: Macrolide antibiotics (Azithromycin, Clarithromycin, Erythromycin). For infants, Azithromycin is preferred. It stops the bacteria from replicating and spreading.
Complication Mechanism: Severe coughing leads to high intrathoracic pressure, which can cause petechiae, subconjunctival hemorrhages, and even rib fractures. Apnea in infants is due to respiratory fatigue and possibly direct toxin effects on the brain.
Memory Tips
Pertussis Priority Acronym: "S.T.O.P. the Spread" S - Start Antibiotics (Azithromycin)
T - Transmission-based (Droplet) Precautions
O - Observe for Apnea (Continuous monitoring)
P - Prevent complications (Hydration, small feeds)
Remember: For infants, think "Contagious and Critical" – treating the contagion (antibiotics) and monitoring the critical airway (apnea risk) are the twin pillars of care.
High-Frequency NCLEX Topics
NCLEX loves to test pertussis! Focus on:
1. Recognizing the classic symptoms (paroxysmal cough with whoop) in a case study.
2. Infant-specific risks (apnea is a bigger concern than the whoop itself).
3. Infection control measures (Droplet Precautions, duration of isolation).
4. Contraindicated interventions (chest physiotherapy).
5. Vaccination prevention (DTaP vaccine schedule).
Watch Out for Question Variations!
Symptom Identification: "The nurse hears a high-pitched inspiratory 'whoop' after a coughing fit in an infant. Which condition should the nurse suspect?"
Safety/Precautions: "Which action should the nurse take first after admitting an infant with suspected pertussis?" (Answer: Place on Droplet Precautions).
Patient Education: "The mother of a 2-month-old asks about the DTaP vaccine. Which statement by the nurse is correct?" (Answer: It protects against pertussis, which can be fatal in young infants).
Priority Shift: If the question adds "The infant is currently cyanotic and apneic after a coughing spell," then the priority immediately shifts to airway management (option 3). Always read the full scenario!
Nursing Clinical Practice GuideClinical Scenario: You are the nurse receiving a 9-month-old, "Liam," from the ED. He has a 7-day history of worsening cough, now with classic "whooping" sounds. He is lethargic between coughing paroxysms. His parents are exhausted and terrified.
Nursing Intervention Strategy:
Immediate Actions (First 5-10 minutes):
Infection Control FIRST: Don appropriate PPE (gown, gloves, mask/eye protection) and place Liam in a private room. Place Droplet Precautions signage. Educate the family on precautions.
Implement Medical Orders: Verify the azithromycin order and administer the first dose STAT. This is a key nursing responsibility to limit transmission in the hospital.
Simultaneous Monitoring: While preparing the medication, ensure Liam is placed on continuous pulse oximetry and cardiorespiratory monitoring. Have suction and emergency airway equipment at the bedside.
Ongoing Assessment & Care:
Apnea Monitoring: Count respiratory rate before, during, and after paroxysms. Document the character and length of coughing fits and any apneic episodes ( >20 seconds).
Supportive Care: Cluster care to minimize disturbance. After a coughing fit, offer small amounts of electrolyte solution via bottle or syringe. Feed small amounts more frequently to reduce risk of vomiting.
Family Support: Teach parents to recognize signs of distress (cyanosis, apnea). Encourage them to keep a calm environment.
Patient Safety and Precautions:
Never leave the infant unattended during the acute phase. Apnea can occur suddenly.
Avoid stimuli that trigger coughing: loud noises, sudden movements, cold air.
Do NOT perform chest physiotherapy or postural drainage.
Medication Caution: Administer azithromycin with or without food as ordered. Monitor for GI side effects (vomiting, diarrhea), which can worsen dehydration.
Nursing Procedure & Medication FlowAdministering Azithromycin (Oral Suspension) to an Infant:
1. Check: Verify order, patient identity (2 identifiers), drug, dose, time. Check for allergies.
2. Prepare: Shake the bottle well. Draw up the exact dose using an oral syringe.
3. Administer: Place infant in a semi-upright position. Administer slowly into the side of the mouth, between the cheek and gum, allowing time to swallow. Never force or squirt rapidly due to aspiration risk.
4. Monitor & Educate: Observe for immediate adverse reactions. Educate parents on the importance of completing the full 5-day course even if symptoms improve.
A Word from Your Senior Nurse
"Pertussis is heartbreaking to see in an infant. Your brain is screaming 'AIRWAY!' and that's absolutely right to monitor vigilantly. But remember, as a nurse, you're also the guardian of the entire unit. Giving that first dose of antibiotics promptly is you putting a shield around every other baby on the floor. NCLEX wants you to think beyond the single patient bed to the broader context of safety and prevention. In practice, you'll learn to do both simultaneously: one nurse hangs the monitor while another draws up the antibiotic. It's this integrated, multi-faceted thinking that defines great nursing care."
