Updated and Latest Questions and Correct Answers with
Rationale
1. Which component of the Pediatric Assessment Triangle (PAT) evaluates the patient’s level
of consciousness and muscle tone?
A. Work of Breathing
B. Circulation to Skin
C. Appearance
D. Airway Patency
Ans: C
Rationale: The Appearance component of the Pediatric Assessment Triangle is designed to assess the
child’s neurologic status and overall clinical severity. It includes evaluating characteristics such as tone,
interactiveness, consolability, look or gaze, and speech or cry. This assessment provides an immediate
‘first look’ at the patient’s brain perfusion and oxygenation levels. Unlike the physical examination, this is
done without touching the child to minimize distress. If a child has poor appearance, it often indicates a
serious underlying physiological problem. The other components of the triangle focus on respiratory and
circulatory systems specifically. Therefore, assessing appearance is the primary way to gauge the mental
status of a pediatric patient quickly.
,2. What is the recommended compression-to-ventilation ratio for two-rescuer infant CPR
according to PALS guidelines?
A. 30:2
B. 5:1
C. 15:2
D. 10:1
Ans: C
Rationale: In two-rescuer pediatric CPR, the ratio of compressions to ventilations is 15:2 to ensure
adequate oxygenation. This differs from the single-rescuer ratio, which remains 30:2 to minimize
interruptions in compressions. Pediatric cardiac arrest is most often caused by respiratory failure rather
than primary cardiac issues, making frequent ventilations crucial. By using a 15:2 ratio, rescuers provide
more breaths per minute to address potential hypoxia. This standard applies to both infants and children
until they reach puberty or adult characteristics. Ensuring high-quality compressions while delivering
effective breaths is a core skill in PALS training. Correct execution of this ratio significantly improves the
chances of survival for the young patient.
,3. When using a manual defibrillator on a pediatric patient, what is the initial recommended
energy dose for the first shock?
A. 1 J/kg
B. 4 J/kg
C. 2 J/kg
D. 10 J/kg
Ans: C
Rationale: The initial energy dose for pediatric defibrillation is 2 Joules per kilogram of the patient’s
body weight. This level is chosen to provide sufficient electrical energy to terminate ventricular
fibrillation while minimizing myocardial damage. If the first shock is unsuccessful, the dose is typically
increased to 4 J/kg for subsequent attempts. PALS guidelines suggest that doses higher than 4 J/kg can be
used, up to a maximum of 10 J/kg or the adult dose. It is essential to use appropriately sized paddles or
pads to ensure the current flows through the heart effectively. Rapid defibrillation is the most effective
treatment for shockable rhythms like pulseless ventricular tachycardia. Providers must also continue
high-quality CPR immediately after the shock is delivered.
, 4. Which of the following is a sign of upper airway obstruction in a pediatric patient?
A. Stridor
B. Expiratory wheezing
C. Crackles
D. Prolonged expiration
Ans: A
Rationale: Stridor is a high-pitched sound heard primarily during inspiration and is a classic indicator of
upper airway obstruction. It is caused by turbulent airflow through a narrowed upper airway, such as the
larynx or trachea. Conditions like croup, epiglottitis, or foreign body aspiration often present with this
specific sound. Expiratory wheezing, on the other hand, usually points to lower airway issues like asthma
or bronchiolitis. Crackles are typically associated with lung tissue diseases such as pneumonia or
pulmonary edema. Recognizing stridor allows the clinician to localize the anatomical site of the
respiratory distress quickly. Management usually involves keeping the child calm and administering
treatments like nebulized epinephrine or steroids. Immediate intervention is required if the stridor
occurs at rest and is accompanied by retractions.
