NCLEX Pediatric Respiratory Practice Questions with Answers

Mastering NCLEX Pediatric Respiratory concepts is essential for nursing students, as respiratory distress remains one of the leading causes of hospitalization and emergency intervention in the pediatric population. Children have unique anatomical differences—such as smaller airways and a higher metabolic rate—that make them more susceptible to rapid respiratory failure compared to adults. This guide provides a deep dive into pediatric respiratory care, offering clinical insights and practice questions to sharpen your critical thinking skills for the exam.

Concept Explanation

NCLEX Pediatric Respiratory nursing focuses on the assessment, intervention, and management of airway patency and gas exchange in infants, children, and adolescents. Because children are not simply "small adults," their respiratory system presents specific challenges: the tongue is proportionally larger, the trachea is narrower, and the chest wall is more compliant (leading to retractions during distress). Understanding these nuances is critical when preparing for the respiratory portion of the NCLEX. Key conditions covered in this topic include Croup (Laryngotracheobronchitis), Epiglottitis, Respiratory Syncytial Virus (RSV)/Bronchiolitis, Asthma, and Cystic Fibrosis.

Anatomical and Physiological Differences

• Airway Diameter: A small amount of edema in a child's airway can reduce the cross-sectional area by 50% or more, significantly increasing airway resistance.
• Obligate Nose Breathers: Infants under 4–6 months primarily breathe through their nose; nasal congestion can lead to significant respiratory distress.
• Diaphragmatic Breathing: Young children rely heavily on the diaphragm; any abdominal distension can impede their ability to breathe effectively.

When assessing a pediatric patient, nurses must monitor for early signs of distress, such as tachypnea, nasal flaring, and irritability. Late signs, including bradycardia, cyanosis, and altered mental status, often indicate impending respiratory arrest.

Solved Examples

1. Priority Intervention for Epiglottitis: A 4-year-old child arrives at the emergency department with a high fever, drooling, and sitting in a "tripod" position. What is the nurse's priority action?
   1. Assess the throat with a tongue depressor.
   2. Obtain a throat culture.
   3. Keep the child calm and notify the provider immediately for intubation equipment.
   4. Start an IV line for antibiotics.
   Solution: The correct answer is 3. Epiglottitis is a medical emergency. Any agitation or invasive procedure (like using a tongue depressor) can trigger a complete airway obstruction. The priority is maintaining a patent airway and preparing for emergency airway management.
2. Asthma Discharge Teaching: A nurse is teaching the parents of a child with asthma how to use a Peak Flow Meter. Which statement by the parent indicates understanding?
   1. "I should record the average of three blows."
   2. "We will use this to determine if his daily medication needs adjustment based on his personal best."
   3. "He should use the meter only when he is having an attack."
   4. "The yellow zone means he is doing great and needs no medicine."
   Solution: The correct answer is 2. Peak flow monitoring helps manage chronic asthma by identifying changes in airway narrowing before symptoms become severe. The "personal best" is the baseline used to determine the Green, Yellow, and Red zones.
3. Cystic Fibrosis Nutrition: A child with Cystic Fibrosis (CF) is prescribed pancreatic enzymes. How should the nurse instruct the parents to administer these?
   1. Give the enzymes once daily in the morning.
   2. Administer enzymes with every meal and snack.
   3. Give the enzymes only if the child has a fatty stool.
   4. Mix the enzymes into a large bowl of hot oatmeal.
   Solution: The correct answer is 2. Because children with CF have thick secretions that block pancreatic ducts, they cannot digest fats and proteins properly. Enzymes must be taken with all food intake to ensure nutrient absorption.

Practice Questions

1. A 2-year-old is hospitalized with Bronchiolitis caused by RSV. Which of the following isolation precautions should the nurse implement?

2. A nurse is caring for an infant with suspected Tetralogy of Fallot who begins to have a "tet spell" (hypercyanotic episode) while crying. What is the immediate nursing action?

3. The nurse is assessing a 7-year-old with a history of asthma who is currently experiencing wheezing and a non-productive cough. The nurse notes that the wheezing has suddenly stopped, and the child appears more lethargic. What does this clinical change suggest?

4. Which of the following findings is considered a hallmark sign of Laryngotracheobronchitis (Croup)?

5. A child with Cystic Fibrosis is undergoing Chest Physiotherapy (CPT). When is the most appropriate time for the nurse to schedule this treatment?

6. A nurse is teaching the mother of a 6-month-old about Sudden Infant Death Syndrome (SIDS) prevention. Which statement by the mother shows a need for further teaching?

7. A 5-year-old is postoperative following a tonsillectomy. Which of the following observations by the nurse would be the most concerning?

8. A nurse is evaluating the sweat chloride test results for a child suspected of having Cystic Fibrosis. Which value is diagnostic for the disease?

9. A child is prescribed a Short-Acting Beta-Agonist (SABA) and an Inhaled Corticosteroid (ICS) for asthma. What is the correct sequence for administration?

Answers & Explanations

1. Answer: Contact and Standard Precautions. RSV is primarily spread through direct contact with respiratory secretions or contaminated surfaces. Although some facilities use droplet precautions, the CDC emphasizes contact precautions for RSV management.
2. Answer: Place the infant in the knee-chest position. This position increases systemic vascular resistance, which helps shunt blood back into the pulmonary circulation, improving oxygenation during a cyanotic spell.
3. Answer: Silent Chest Syndrome (Impending Respiratory Failure). The sudden cessation of wheezing in an asthmatic patient often indicates that air movement has become so restricted that no sound is produced. This is an emergency requiring immediate intervention.
4. Answer: Barking, brassy cough and inspiratory stridor. These symptoms result from edema and inflammation in the subglottic area of the larynx.
5. Answer: Before meals or at least 2 hours after meals. CPT can induce vomiting if performed on a full stomach. Performing it before meals also helps clear the airway so the child can breathe better while eating.
6. Answer: "I will place my baby on her stomach to sleep so she doesn't choke." The "Back to Sleep" campaign by the American Academy of Pediatrics recommends supine positioning to reduce SIDS risk.
7. Answer: Frequent swallowing or throat clearing. This is a classic sign of post-tonsillectomy hemorrhage, as the child is swallowing trickling blood.
8. Answer: A chloride concentration greater than $60 \text{ mEq/L}$. Values between $40-59 \text{ mEq/L}$ are suggestive, but $\geq 60 \text{ mEq/L}$ is considered diagnostic for Cystic Fibrosis.
9. Answer: Administer the SABA first, wait 5 minutes, then administer the ICS. The bronchodilator (SABA) opens the airways, allowing the corticosteroid to penetrate deeper into the lung tissue.
10. Answer: Oxygen Tent or Oxy-Hood. For toddlers, an oxygen tent allows for high humidity and oxygen concentration without the distress of a facial mask, though it makes assessment more difficult.

Quick Quiz

Frequently Asked Questions

What are the early signs of respiratory distress in an infant?

Early signs include tachypnea, nasal flaring, and mild intercostal retractions. Parents may also notice the infant becoming increasingly irritable or having difficulty feeding due to the effort required to breathe.

Why is Epiglottitis considered more dangerous than Croup?

Epiglottitis is a bacterial infection that causes rapid swelling of the epiglottis, which can lead to total airway obstruction within minutes. Unlike Croup, which is usually viral and managed with cool mist, Epiglottitis requires emergency stabilization of the airway.

How is RSV different from a common cold in infants?

While RSV starts with cold-like symptoms, it often progresses to bronchiolitis in infants, causing significant mucus production and lower airway inflammation. This can lead to wheezing, retractions, and apnea, which are not typical of a standard cold.

What is the purpose of a spacer with a Metered-Dose Inhaler (MDI)?

A spacer holds the medication in a chamber after it is released, allowing the child to inhale the medicine slowly and deeply. This ensures that more of the drug reaches the lungs rather than being trapped in the mouth or throat.

Can a child with Cystic Fibrosis participate in sports?

Yes, physical activity is highly encouraged as it helps promote mucus clearance and improves pulmonary function. However, these children must stay hydrated and may need extra salt intake, especially in hot weather, due to salt loss in their sweat.

What is the priority nursing diagnosis for a child with Bronchiolitis?

The priority diagnosis is Impaired Gas Exchange or Ineffective Airway Clearance. Nursing interventions focus on suctioning the nares, maintaining hydration, and monitoring oxygen saturation levels to ensure the child remains stable.
