PCP Pediatric Emergencies 2 — Questions and Answers
Question 1: For a 10 kg child in cardiac arrest, what is the correct defibrillation dose?
- 1 J/kg (10 J)
- 2 J/kg (20 J) (Correct answer)
- 4 J/kg (40 J)
- 360 J
Correct answer: 2 J/kg (20 J)
Initial pediatric defibrillation is 2 J/kg; subsequent shocks are 4 J/kg.
Question 2: Croup (laryngotracheobronchitis) is most recognizable by:
- Drooling and toxic appearance
- Barking seal-like cough and stridor (Correct answer)
- Wheezing throughout all lung fields
- Silent chest and cyanosis
Correct answer: Barking seal-like cough and stridor
Croup causes characteristic barking cough and inspiratory stridor due to subglottic edema.
Question 3: The Broselow tape is used in pediatric emergencies to:
- Assess neurological function
- Estimate weight-based drug dosing and equipment sizing (Correct answer)
- Measure blood pressure in small children
- Determine respiratory rate norms
Correct answer: Estimate weight-based drug dosing and equipment sizing
The Broselow tape uses a child's length to estimate weight and provides color-coded drug doses and equipment sizes.
Question 4: Signs of dehydration in a pediatric patient include all of the following EXCEPT:
- Dry mucous membranes
- Sunken fontanelle in infants
- Decreased urine output
- Bounding peripheral pulses (Correct answer)
Correct answer: Bounding peripheral pulses
Dehydration causes weak, not bounding, pulses due to reduced circulating volume.
Question 5: Which of the following best describes compensated shock in a pediatric patient?
- Hypotension and altered mental status
- Normal blood pressure with tachycardia and poor perfusion (Correct answer)
- Bradycardia with normal skin color
- Hypertension with warm, flushed skin
Correct answer: Normal blood pressure with tachycardia and poor perfusion
Children compensate for shock by maintaining near-normal BP through tachycardia and vasoconstriction — hypotension is a late, ominous sign.
Question 6: What is the appropriate management for a suspected foreign body airway obstruction in a conscious infant?
- Blind finger sweep and back blows only
- 5 back blows alternating with 5 chest thrusts (Correct answer)
- 5 abdominal thrusts (Heimlich)
- Immediate BVM ventilation
Correct answer: 5 back blows alternating with 5 chest thrusts
Conscious infants with FBAO are treated with alternating 5 back blows and 5 chest thrusts, not abdominal thrusts.
