PRACTICE TEST | CERTIFICATION PREPARATION
1. A 6-year-old child presents with wheezing, prolonged expiration, and use of accessory
muscles. What is the most likely initial condition?
A. Pneumonia
B. Asthma exacerbation
C. Foreign body obstruction
D. Heart failure
Correct Answer: B. Asthma exacerbation
Rationale: Wheezing with prolonged expiration and accessory muscle use strongly indicates
bronchospasm consistent with asthma. Pneumonia may present with fever and crackles,
foreign body obstruction is typically sudden and localized, and heart failure would more likely
present with crackles and edema.
2. Which oxygen delivery method is most appropriate for a child with severe respiratory
distress?
A. Nasal cannula
B. Simple face mask
C. Non-rebreather mask
D. Room air observation
Correct Answer: C. Non-rebreather mask
Rationale: A non-rebreather provides high-concentration oxygen for severe distress. Nasal
cannula and simple mask deliver lower oxygen concentrations, and observation alone is
unsafe in severe distress.
3. A child is choking but still able to cough weakly. What is the appropriate action?
A. Perform abdominal thrusts immediately
B. Encourage continued coughing
C. Begin CPR
D. Perform blind finger sweep
Correct Answer: B. Encourage continued coughing
Rationale: Effective coughing indicates partial airway obstruction. Interventions like thrusts or
CPR are only indicated if the obstruction becomes severe or the child becomes unresponsive.
4. Which sign is most concerning for impending respiratory failure in a pediatric patient?
A. Tachypnea
B. Mild wheezing
C. Bradypnea and decreased effort
D. Fever
Correct Answer: C. Bradypnea and decreased effort
Rationale: A slowing respiratory rate and reduced effort suggest fatigue and impending
failure. Tachypnea is an early compensatory sign, while fever is nonspecific.
,5. What is the first step in managing suspected croup with stridor at rest?
A. Antibiotics
B. Nebulized epinephrine
C. Immediate intubation
D. Chest physiotherapy
Correct Answer: B. Nebulized epinephrine
Rationale: Nebulized epinephrine rapidly reduces airway swelling. Antibiotics are not
indicated for viral croup, and intubation is reserved for extreme failure.
6. A child with asthma is not improving after initial albuterol treatment. What is the next best
step?
A. Stop all treatment
B. Add systemic corticosteroids
C. Switch to antibiotics
D. Reduce oxygen flow
Correct Answer: B. Add systemic corticosteroids
Rationale: Corticosteroids reduce airway inflammation and are indicated when
bronchodilators alone are insufficient.
7. Which breath sound is most consistent with upper airway obstruction?
A. Crackles
B. Stridor
C. Pleural rub
D. Wheezing
Correct Answer: B. Stridor
Rationale: Stridor indicates upper airway narrowing. Wheezing is lower airway, crackles
relate to fluid, and pleural rub is pleural inflammation.
8. A child is unconscious with no breathing and no pulse. What is the correct initial action?
A. Check glucose
B. Start CPR
C. Give oxygen via mask
D. Perform abdominal thrusts
Correct Answer: B. Start CPR
Rationale: Absence of breathing and pulse requires immediate CPR. Other interventions delay
life-saving measures.
9. Which finding indicates respiratory distress rather than respiratory failure?
A. Cyanosis
B. Decreased consciousness
C. Tachypnea with retractions
D. Apnea
Correct Answer: C. Tachypnea with retractions
Rationale: Distress shows increased work of breathing. Cyanosis, apnea, and altered
consciousness indicate failure.
10. A child has a suspected anaphylactic reaction causing airway swelling. What medication is
first-line?
A. Diphenhydramine
B. Epinephrine
, C. Albuterol
D. Steroids alone
Correct Answer: B. Epinephrine
Rationale: Epinephrine reverses airway swelling and systemic effects. Antihistamines and
steroids are adjuncts, not first-line.
11. Which oxygen device provides the lowest concentration of oxygen?
A. Non-rebreather mask
B. Simple face mask
C. Nasal cannula
D. Bag-valve mask
Correct Answer: C. Nasal cannula
Rationale: Nasal cannula delivers the lowest FiO₂ compared to masks and BVM.
12. A child with bronchiolitis presents with nasal flaring and poor feeding. What is the
priority?
A. Antibiotics
B. Airway and oxygen support
C. Immediate discharge
D. Diuretics
Correct Answer: B. Airway and oxygen support
Rationale: Bronchiolitis is viral; management focuses on oxygenation and supportive care.
13. Which condition most commonly causes sudden respiratory distress after eating peanuts?
A. Asthma
B. Foreign body aspiration
C. Pneumonia
D. Bronchiolitis
Correct Answer: B. Foreign body aspiration
Rationale: Sudden onset during eating suggests aspiration of a solid object.
14. What is a late sign of hypoxia in children?
A. Tachycardia
B. Restlessness
C. Bradycardia
D. Nasal flaring
Correct Answer: C. Bradycardia
Rationale: Bradycardia indicates severe hypoxia and impending arrest in pediatrics.
15. A child is breathing at 8 breaths per minute and unresponsive. What does this indicate?
A. Mild distress
B. Normal variation
C. Respiratory failure
D. Anxiety
Correct Answer: C. Respiratory failure
Rationale: Severely decreased respiratory rate with unresponsiveness indicates failure.
16. Which intervention is most appropriate for mild asthma symptoms at home?
A. Immediate intubation
B. Short-acting bronchodilator
