Updated and Latest Questions and Correct Answers with
Rationale
1. The Pediatric Assessment Triangle (PAT) is a rapid evaluation tool that consists of which
three components?
A. Appearance, Work of Breathing, and Circulation to the Skin
B. Airway, Breathing, and Circulation
C. Blood Pressure, Heart Rate, and Respiratory Rate
D. Level of Consciousness, Pupil Reaction, and Motor Response
Ans: A
Rationale: The Pediatric Assessment Triangle is designed to be a rapid, across-the-room assessment tool.
It allows healthcare providers to identify the severity of a child’s condition within seconds. The first
component is Appearance, which reflects the adequacy of oxygenation and brain perfusion. The second
component is Work of Breathing, which serves as an indicator of respiratory status. The third component
is Circulation to the Skin, which assesses overall cardiovascular output. This tool does not require
equipment such as a stethoscope or blood pressure cuff. It helps determine if the child requires
immediate life-saving interventions. By using the PAT, providers can categorize patients into groups such
as respiratory distress or shock.
,2. A 4-year-old child presents with a barking cough, inspiratory stridor, and mild retractions.
What is the most likely diagnosis?
A. Asthma exacerbation
B. Croup (Laryngotracheobronchitis)
C. Foreign body aspiration
D. Bacterial pneumonia
Ans: B
Rationale: Croup is a common upper airway obstruction in children characterized by subglottic swelling.
The classic presentation includes a ‘barking’ cough that sounds like a seal. Stridor is often heard during
inspiration due to the narrowed airway passage. Patients may also demonstrate varying degrees of chest
wall retractions depending on the severity. Unlike asthma, which presents with wheezing, croup
primarily affects the upper respiratory tract. Initial management often involves keeping the child calm
and administering corticosteroids. In severe cases, racemic epinephrine may be used to reduce airway
edema. This condition is typically viral in origin and often worsens at night.
3. What is the recommended dose of Epinephrine for a pediatric patient in cardiac arrest?
A. 0.01 mg/kg of 1:10,000 concentration
B. 0.1 mg/kg of 1:10,000 concentration
C. 1 mg/kg of 1:1,000 concentration
D. 0.01 mg/kg of 1:1,000 concentration
Ans: A
,Rationale: Epinephrine is a crucial medication used during pediatric resuscitation for its alpha-
adrenergic effects. The standard IV or IO dose is 0.01 mg/kg using the 0.1 mg/mL (1:10,000)
concentration. This dosage should be repeated every 3 to 5 minutes during cardiac arrest. It works by
increasing systemic vascular resistance and improving coronary perfusion pressure. Higher doses are no
longer recommended as they do not improve outcomes and may cause harm. Accurate weight-based
dosing is essential to avoid toxicity or under-dosing. Providers should use a length-based resuscitation
tape if the child’s exact weight is unknown. Always follow each dose with a saline flush to ensure the
medication reaches the central circulation.
4. A 10-year-old child is unresponsive and has no pulse. The monitor shows Ventricular
Fibrillation (VF). What is the first action to take?
A. Deliver an unsynchronized shock at 2 J/kg
B. Perform 2 minutes of CPR
C. Deliver a synchronized cardioversion shock at 1 J/kg
D. Administer 0.01 mg/kg of Epinephrine
Ans: A
Rationale: Ventricular Fibrillation is a shockable rhythm that requires immediate defibrillation.
According to PALS protocols, the initial energy dose for defibrillation is 2 J/kg. If the first shock is
unsuccessful, the energy should be increased for subsequent shocks. Rescuers should resume high-
quality CPR immediately after the shock is delivered without checking the rhythm. Epinephrine should be
administered if VF persists after the second shock. Early defibrillation is the single most important factor
in surviving a shockable cardiac arrest. Delays in delivery of the shock decrease the likelihood of
, returning to a perfusing rhythm. Always ensure that the environment is safe and all staff are ‘clear’ before
discharging the energy.
5. In a child with septic shock, what is the initial fluid bolus volume and timing?
A. 20 mL/kg over 5 to 10 minutes
B. 10 mL/kg over 1 hour
C. 5 mL/kg over 30 minutes
D. 20 mL/kg over 2 hours
Ans: A
Rationale: Septic shock requires aggressive fluid resuscitation to restore intravascular volume and
improve tissue perfusion. The standard initial bolus is 20 mL/kg of an isotonic crystalloid solution like
Normal Saline. This should be delivered rapidly, typically over 5 to 10 minutes, to effectively treat
hypotension. Providers must frequently reassess the patient for signs of fluid overload, such as
hepatomegaly or crackles. If perfusion does not improve, additional boluses may be necessary up to 40-
60 mL/kg in the first hour. Early administration of antibiotics is also a critical component of the sepsis
bundle. If shock persists despite fluid resuscitation, vasoactive medications like epinephrine or
norepinephrine should be initiated. Rapid IV or IO access is essential for the successful management of
these critically ill children.
