Medium NCLEX Pediatric Respiratory Practice Questions

Mastering pediatric respiratory care is essential for nursing students, as respiratory distress is one of the most common reasons for pediatric emergency admissions. These medium NCLEX pediatric respiratory practice questions focus on the anatomical differences in children, common pathologies like bronchiolitis and croup, and the critical nursing interventions required to maintain airway patency.

Concept Explanation

Pediatric respiratory care involves the assessment and management of airway, breathing, and oxygenation in infants and children, whose physiological structures are significantly smaller and more prone to obstruction than adults. Because children have higher metabolic rates and oxygen consumption, respiratory failure can occur rapidly if interventions are delayed. Key concepts include understanding the narrowness of the pediatric airway, where even $1 \text{ mm}$ of edema can reduce the airway diameter by $50\%$ in an infant.

Nurses must distinguish between upper airway disorders, such as Laryngotracheobronchitis (Croup) and Epiglottitis, and lower airway disorders like Asthma and Cystic Fibrosis. Assessment focuses on work of breathing (WOB), including nasal flaring, grunting, and retractions (intercostal, subcostal, or suprasternal). For comprehensive study, you might also explore NCLEX Pediatric Respiratory Practice Questions with Answers for a broader overview of these conditions.

According to the American Academy of Pediatrics, monitoring pulse oximetry and respiratory rate is vital, but clinical appearance—such as level of consciousness and skin color—often provides the earliest clues to impending respiratory arrest. Effective management often involves the use of AI-powered flashcards to memorize developmental milestones and normal vital sign ranges for different pediatric age groups.

Solved Examples

1. Example: Assessing Retractions
   A 6-month-old infant is admitted with Respiratory Syncytial Virus (RSV). The nurse notes the skin between the ribs is pulling inward during inspiration. How should the nurse document this finding?
   1. Identify the location of the pulling: Between the ribs is "intercostal."
   2. Identify the action: Pulling inward during inspiration is a "retraction."
   3. Combine the terms: Document as "intercostal retractions."
   4. Assess severity: Retractions indicate increased work of breathing and require immediate notification of the provider if new or worsening.
2. Example: Epiglottitis Positioning
   A child arrives at the emergency department with a high fever, drooling, and a muffled voice. The child is sitting upright, leaning forward with the chin out (tripod position). What is the priority nursing action?
   1. Recognize the signs: Drooling, tripod positioning, and muffled voice are classic signs of epiglottitis.
   2. Safety first: Do not examine the throat with a tongue depressor, as this can cause total airway occlusion.
   3. Keep the child calm: Anxiety increases oxygen demand and can worsen the obstruction.
   4. Preparation: Ensure emergency intubation or tracheostomy equipment is at the bedside.
3. Example: Asthma Medication Sequence
   A 10-year-old is prescribed Albuterol and Fluticasone via Metered-Dose Inhaler (MDI). Which medication should the nurse instruct the child to use first?
   1. Determine the drug classes: Albuterol is a short-acting beta-agonist (bronchodilator); Fluticasone is a corticosteroid (anti-inflammatory).
   2. Apply the principle: Bronchodilators should be used first to open the airways.
   3. Explain the rationale: Opening the airways first allows the corticosteroid to penetrate deeper into the lungs.
   4. Wait time: Instruct the child to wait 5 minutes between the two different medications.

Answers & Explanations

1. Answer: Exposure to cool mist or cold night air.
Croup (Laryngotracheobronchitis) involves edema of the larynx and trachea. Cool mist from a humidifier or taking the child outside into the cold air helps constrict edematous blood vessels and decrease airway swelling. This is a standard recommendation for mild croup cases that do not involve respiratory distress at rest. For more on general pediatric care, see NCLEX Pediatric Practice Questions with Answers.

2. Answer: Contact and Droplet precautions.
RSV is primarily spread through direct contact with secretions or contaminated surfaces, but it can also be spread via large droplets. Therefore, the nurse should wear a gown and gloves (Contact) and a mask (Droplet) when entering the room. Proper PPE prevents the spread of this highly contagious virus in the pediatric unit.

3. Answer: One hour before or two hours after meals.
CPT is designed to mobilize thick secretions in CF patients. It should not be done immediately after meals because the vigorous percussion can induce vomiting or gastroesophageal reflux. Scheduling it before meals helps clear the airway so the child can breathe better while eating.

4. Answer: Frequent swallowing or throat clearing.
Following a tonsillectomy, frequent swallowing is the classic sign of post-operative bleeding. The nurse must assess the back of the throat with a flashlight and notify the surgeon immediately, as this is a surgical emergency. You can practice more prioritization scenarios using a standardized exam simulator.

5. Answer: The Yellow Zone.
The Asthma Action Plan uses a traffic light system: Green is $80-100\%$, Yellow is $50-80\%$, and Red is below $50\%$. A reading of $65\%$ indicates that the asthma is not well-controlled and may require a change in medication or use of a "rescue" inhaler as prescribed by the provider.

6. Answer: Administer the enzymes with every meal and snack.
In cystic fibrosis, thick mucus blocks the pancreatic ducts, preventing enzymes from reaching the duodenum. For proper absorption of fats and proteins, these enzymes must be present in the gut at the same time as food. They should not be crushed or chewed.

7. Answer: Repetitive coughing followed by a high-pitched "whoop" during inhalation.
Pertussis progresses through stages. The paroxysmal stage is characterized by violent coughing fits that make it difficult to breathe, often ending with the characteristic "whooping" sound as the child tries to inhale. This stage can last several weeks.

8. Answer: Oxygen Tent (Croup Tent) or Oxygen Hood.
For toddlers who often pull off masks or nasal cannulas, an oxygen tent or hood can provide a high-humidity, high-oxygen environment. However, for a precise high concentration, a hood is often used for infants, while older toddlers may require high-flow nasal cannula therapy which is better tolerated than a standard mask.

9. Answer: The right bronchus is shorter, wider, and more vertical than the left.
Because of this vertical alignment, gravity and the path of least resistance usually direct aspirated foreign bodies into the right lung rather than the left. This is a key anatomical difference taught in Khan Academy's respiratory lessons.

10. Answer: Restlessness and irritability.
In pediatrics, behavioral changes like restlessness, anxiety, or irritability are often the very first signs that oxygen levels are dropping (hypoxia). Cyanosis is a late sign and indicates that the child is decompensating. For more advanced respiratory topics, check out Hard NCLEX Respiratory Practice Questions.

Quick Quiz

Frequently Asked Questions

What is the difference between croup and epiglottitis?

Croup is typically a viral infection causing a barking cough and subglottic swelling, usually managed with cool mist. Epiglottitis is a bacterial emergency characterized by high fever, drooling, and supraglottic swelling that can lead to rapid airway obstruction.

Why is chest physiotherapy important for cystic fibrosis?

CPT uses percussion and vibration to loosen the thick, tenacious mucus that accumulates in the lungs of CF patients. Clearing these secretions is vital to prevent chronic infections and improve gas exchange.

How do I identify respiratory distress in a newborn?

Key signs include nasal flaring, grunting on expiration, and significant retractions. Because newborns are obligatory nose breathers, any nasal congestion or obstruction can lead to rapid distress.

What should I do if a child with asthma has a peak flow in the Red Zone?

A Red Zone reading (less than $50\%$ of personal best) indicates a medical emergency. The nurse or parent should administer the rescue inhaler immediately and seek emergency medical care or call 911.

Can RSV be treated with antibiotics?

No, RSV is a viral infection, so antibiotics are not effective against the virus itself. Treatment is primarily supportive, focusing on hydration, oxygenation, and suctioning of nasal secretions.

What are the common triggers for pediatric asthma?

Common triggers include allergens (pollen, pet dander), exercise, cold air, tobacco smoke, and viral respiratory infections. Identifying and avoiding these triggers is a cornerstone of long-term asthma management.
