A 3-month-old infant is admitted to the pediatric unit with suspected pertussis. The infant has been experiencing paroxysmal coughing episodes followed by a characteristic "whoop" sound. What is the most critical nursing intervention to implement immediately?
1Maintain the infant in a position to facilitate airway clearance during coughing episodes✓ 정답
2Administer prescribed antibiotics immediately to reduce transmission
3Provide supplemental oxygen via nasal cannula at 2 L/min
4Encourage frequent feeding to maintain nutritional status
해설
Positioning to facilitate airway clearance is critical to prevent aspiration and respiratory compromise in infants with pertussis. Antibiotics and oxygen are important but secondary to immediate airway management.
Core Nursing ExplanationKey Concept Analysis: This question assesses the priority nursing intervention for an infant with Pertussis (Whooping cough). Pertussis is a highly contagious bacterial infection caused by Bordetella pertussis. The hallmark symptom is severe, uncontrollable coughing paroxysms that can lead to Key Point!Apnea (cessation of breathing), cyanosis, and vomiting, which pose a high risk for Aspiration and respiratory failure, especially in infants under 6 months of age. The primary threat is not the infection itself during the paroxysmal stage, but the mechanical consequences of the violent coughing.
Answer Rationale: The most critical, immediate intervention is Maintaining the infant in a position to facilitate airway clearance. During a coughing paroxysm, placing the infant on their side or in a semi-upright position helps Key Point!prevent aspiration of mucus or vomitus and promotes drainage of secretions. This is a direct, life-preserving action that addresses the ABCs (Airway, Breathing, Circulation) – airway patency is always the top priority. This intervention is under the nurse's independent scope of practice and must be implemented instantly during and after coughing episodes.
Distractor Analysis:
Watch out for confusion! Option ②, administering antibiotics, is important for reducing transmission to others but has limited impact on the course of the illness once the paroxysmal coughing stage has begun. Antibiotics do not rapidly resolve the coughing spells. While it should be done, it is not the immediate critical action during a clinical crisis.
Option ③, providing supplemental oxygen, may be necessary if the infant is hypoxic, but the question does not present data indicating cyanosis or low oxygen saturation. Oxygen is a dependent intervention (requires an order) and is not the first action; securing the airway comes first.
Option ④, encouraging frequent feeding, is a supportive care measure to prevent dehydration and malnutrition, which can occur due to vomiting. However, feeding immediately after a paroxysm can increase the risk of aspiration. Nutritional support is important but secondary to immediate airway safety.
Related Concepts: Nursing care for pertussis also includes droplet isolation precautions, monitoring for apnea (may require cardiorespiratory monitoring), suctioning secretions gently, ensuring hydration, and providing family education on the disease course and the critical importance of the DTaP/Tdap vaccination to prevent future cases.

Greatest Risk in Infants
Airway compromise, apnea, cyanosis, aspiration pneumonia, seizures from hypoxia.
Priority Nursing Focus (ABCs)
Airway management and prevention of aspiration during coughing episodes.
Secondary Interventions
Antibiotics (Macrolides like Azithromycin), droplet isolation, hydration, nutrition, family support.
Side-by-Side Comparison!
Intervention
Priority Level & Rationale
Timing
Airway Positioning
Highest Priority. Directly prevents life-threatening aspiration and hypoxia.
Immediate, during and after coughing paroxysms.
Administer Antibiotics
Important but Secondary. Limits spread but does not stop current paroxysms.
Should be given promptly, but not instead of airway care.
Provide Oxygen
Supportive. Used based on assessment findings (e.g., SpO2 < 92%).
After airway is secured, if indicated.
Anatomy, Physiology & Pharmacology PointsAirway Anatomy in Infants: Infants have proportionally larger tongues, narrower airways, and less developed cough reflexes, making them exceptionally vulnerable to airway obstruction from secretions.
Pertussis Toxin: Causes lymphocytosis and impairs the immune response, but the severe cough is primarily due to ciliary damage and neural pathway irritation.
First-Line Antibiotic: Azithromycin. It eradicates the bacteria from the nasopharynx, shortening the period of communicability. Prophylaxis is also given to close contacts.
Memory TipsABCs for Pertussis: Airway first, Breathing (oxygen) second, Circulation/Comfort/Communicability (antibiotics) third.
The "Whoop" is a Warning: The characteristic sound is the infant gasping for air after a series of coughs. Think: "Whoop! – Watch the Airway!"
High-Frequency NCLEX Topics
NCLEX loves to test priority-setting in pediatric respiratory emergencies. Pertussis is a classic case. Always ask yourself: "What is the immediate threat to life?" For an infant coughing violently, the threat is airway obstruction and aspiration – not the medication schedule or feeding time.
Watch Out for Question Variations!
* Shift to "Safety": "The nurse is caring for an infant with pertussis. Which action requires immediate correction?" (Answer: A nursing assistant feeding the infant upright immediately after a severe coughing spell – this increases aspiration risk; side-lying is safer).
* Shift to "Transmission-Based Precautions": "What type of isolation is required for an infant with pertussis?" (Answer: Droplet Precautions – mask for close contact).
* Shift to "Assessment": "Which finding in an infant with pertussis should be reported to the provider immediately?" (Answer: Apnea for >20 seconds or cyanosis).
Nursing Clinical Practice GuideClinical Scenario: You are the nurse on a pediatric unit. You hear the 3-month-old patient, Baby Liam, begin a coughing fit – 10-15 rapid coughs in succession without taking a breath, his face turning red, followed by the high-pitched "whooping" inhale. He then vomits a small amount of milky fluid.Nursing Intervention Strategy:
1Immediate Action (Assessment & Intervention)Quickly go to the crib. Gently turn Liam onto his side (left lateral position is often preferred). This allows secretions and vomitus to drain from his mouth. Have a suction device (bulb syringe) ready at the bedside and suction the mouth gently if needed. Stay with him, speaking calmly.
2Post-Paroxysm CareAfter the episode, keep him on his side, assess his breathing rate and effort, and check for cyanosis. Allow him to rest; handling or stimulating him can trigger another paroxysm.
3Ongoing ManagementCluster your care (vitals, feeding, assessment) during quiet periods. Implement droplet precautions (wear a mask within 3 feet of the patient). Administer prescribed azithromycin. Educate the parents on the disease course, the critical importance of positioning, and signs of distress (listlessness, apnea, cyanosis).
Patient Safety and Precautions:
* Aspiration Risk: Never feed the infant during or immediately after a coughing spell. Wait at least 30 minutes after a severe paroxysm to attempt feeding.
* Suctioning: Use a bulb syringe for the mouth only. Deep nasopharyngeal suctioning is generally avoided as it can trigger more coughing and laryngospasm.
* Stimulation: Minimize environmental stimuli (loud noises, bright lights) which can trigger paroxysms.
Nursing Procedure & Medication FlowProcedure: Positioning During a Pertussis Paroxysm
1. Remain calm. Call for assistance if needed.
2. Turn infant to side or hold upright, slightly forward, supporting head and neck.
3. Clear mouth of secretions/vomitus with bulb syringe.
4. Monitor for effective breathing and color.
5. Document the episode: duration, presence of whoop/vomit/cyanosis/apnea.
Medication: Azithromycin
* Action: Macrolide antibiotic. Eradicates Bordetella pertussis.
* Nursing Consideration: Give as ordered, usually once daily. Monitor for GI side effects. Complete the full course. Educate family that it will not stop current coughing fits but is crucial to stop the spread.
A Word from Your Senior Nurse
"Caring for a 'whooping' infant can be scary, even for experienced nurses. Your calm, quick action to position that baby on their side is the single most important thing you can do in that moment. You are physically creating a safe pathway for their airway. In pediatrics, we often say 'airway, airway, airway' – and this is a perfect example of why. Trust your ABCs. That foundational knowledge will guide you through this and countless other emergencies, making you a confident and capable nurse at the bedside."
Pertussis — A highly contagious respiratory tract infection, also known as whooping cough, characterized by severe coughing paroxysms followed by a high-pitched "whoop" on inspiration.
Paroxysmal Cough — A sudden, recurrent episode of violent, uncontrollable coughing. In pertussis, these can lead to vomiting, cyanosis, and apnea.
Aspiration — The inhalation of oropharyngeal or gastric contents into the lower respiratory tract. A major risk during pertussis coughing spells, especially in infants.
Droplet Precautions — Infection control measures used for pathogens spread through large respiratory droplets (e.g., pertussis, influenza). Requires a mask for close contact.
Azithromycin — A macrolide antibiotic that is the first-line treatment for pertussis. It helps eliminate the bacteria and reduce transmission but does not rapidly resolve symptoms.
