Sample Questions and Answers with Detailed Explanations

Disclaimer: The following questions and answers are provided as examples and may not exactly match the questions on your specific PALS precourse self-assessment. The content is intended to illustrate the types of questions you may encounter and provide a foundation for understanding the underlying principles.

Question 1:

A 6-month-old infant presents with increased work of breathing, intercostal retractions, and nasal flaring. The infant is alert but irritable. What is the MOST appropriate initial intervention?

a) Administering a bolus of normal saline.

b) Providing supplemental oxygen.

c) Initiating chest compressions.

d) Administering epinephrine.

Answer: b) Providing supplemental oxygen.

Explanation: The infant exhibits signs of respiratory distress. The MOST appropriate initial intervention is to address the respiratory compromise by providing supplemental oxygen. While further assessment is needed, improving oxygenation is the priority. Options a, c, and d are not indicated at this stage. Fluid boluses are used for shock, chest compressions for cardiac arrest, and epinephrine for specific arrhythmias or anaphylaxis.

Question 2:

A 4-year-old child is found unresponsive and apneic. You check for a pulse and find none. What is the NEXT step in managing this patient?

a) Administer epinephrine.

b) Initiate chest compressions.

c) Establish intravenous (IV) access.

d) Prepare for intubation.

Answer: b) Initiate chest compressions.

Explanation: The child is in cardiac arrest (unresponsive, apneic, and pulseless). According to the PALS algorithm, the NEXT step is to initiate chest compressions. High-quality chest compressions are crucial for maintaining circulation and delivering oxygen to the vital organs. Epinephrine (a) is administered later in the algorithm. IV access (c) and intubation (d) are important but secondary to starting compressions.

Question 3:

Which of the following is the MOST common cause of cardiac arrest in children?

a) Primary cardiac disease.

b) Sudden infant death syndrome (SIDS).

c) Respiratory failure or shock.

d) Congenital heart defects.

Answer: c) Respiratory failure or shock.

Explanation: Unlike adults, where cardiac arrest is often caused by primary cardiac disease, the MOST common cause of cardiac arrest in children is respiratory failure or shock. This highlights the importance of early recognition and management of respiratory and circulatory problems in pediatric patients. Options a, b, and d are less common causes of cardiac arrest in children.

Question 4:

The recommended compression rate for chest compressions in infants and children is:

a) 60-80 compressions per minute.

b) 80-100 compressions per minute.

c) 100-120 compressions per minute.

d) 120-140 compressions per minute.

Answer: c) 100-120 compressions per minute.

Explanation: The recommended compression rate for chest compressions in infants and children is 100-120 compressions per minute. It is crucial to maintain an adequate rate to ensure effective circulation. The compression depth should be at least one-third the anterior-posterior diameter of the chest.

Question 5:

You are caring for a 10-year-old child with supraventricular tachycardia (SVT). The child is hemodynamically stable. Which of the following is the FIRST intervention you should attempt?

a) Synchronized cardioversion.

b) Adenosine administration.

c) Vagal maneuvers.

d) Amiodarone administration.

Answer: c) Vagal maneuvers.

Explanation: For a hemodynamically stable child with SVT, the FIRST intervention should be vagal maneuvers. These maneuvers, such as applying ice to the face or having the child blow into a syringe, can sometimes terminate the SVT without the need for medication. If vagal maneuvers are unsuccessful, adenosine (b) is the next line of treatment. Synchronized cardioversion (a) is reserved for unstable patients, and amiodarone (d) is used for more resistant arrhythmias.

Question 6:

What is the correct dose of epinephrine for a child in cardiac arrest?

a) 0.01 mg/kg IV/IO.

b) 0.1 mg/kg IV/IO.

c) 0.01 mg/kg ET.

d) 0.1 mg/kg ET.

Answer: a) 0.01 mg/kg IV/IO.

Explanation: The correct dose of epinephrine for a child in cardiac arrest is 0.01 mg/kg IV/IO (intravenous/intraosseous). This dose should be repeated every 3-5 minutes. The endotracheal (ET) route is no longer routinely recommended due to inconsistent absorption.

Question 7:

What is the recommended initial energy dose for synchronized cardioversion in children?

a) 0.5-1 joules/kg.

b) 2 joules/kg.

c) 4 joules/kg.

d) 6 joules/kg.

Answer: a) 0.5-1 joules/kg.

Explanation: The recommended initial energy dose for synchronized cardioversion in children is 0.5-1 joules/kg. If the initial shock is unsuccessful, the energy dose can be increased to 2 joules/kg for subsequent shocks.

Question 8:

A 3-year-old child presents with severe respiratory distress, drooling, and a high fever. The child is sitting upright and refusing to lie down. What condition should you suspect?

a) Asthma exacerbation.

b) Croup.

c) Epiglottitis.

d) Bronchiolitis.

Answer: c) Epiglottitis.

Explanation: The presentation is classic for epiglottitis, a bacterial infection of the epiglottis that can cause rapid airway obstruction. The "tripod" position (sitting upright and leaning forward) and drooling are characteristic signs. Asthma (a), croup (b), and bronchiolitis (d) are less likely given the acute onset and severity of the symptoms.

Question 9:

Which of the following is a sign of compensated shock in a child?

a) Hypotension.

b) Bradycardia.

c) Altered mental status.

d) Tachycardia.

Answer: d) Tachycardia.

Explanation: In compensated shock, the body attempts to maintain blood pressure and perfusion. Tachycardia (increased heart rate) is an early sign of this compensation. Hypotension (a), bradycardia (b), and altered mental status (c) are signs of decompensated shock, indicating that the compensatory mechanisms are failing.

Question 10:

You are preparing to administer adenosine to a child with SVT. Which of the following is MOST important to remember?

a) Administer the adenosine slowly over 5 minutes.

b) Flush the IV line with saline immediately after adenosine administration.

c) Use a distal IV site for administration.

d) Monitor the child for hypertension after administration.

Answer: b) Flush the IV line with saline immediately after adenosine administration.

Explanation: Adenosine has a very short half-life (seconds). It is MOST important to flush the IV line with saline immediately after administration to ensure the medication reaches the heart quickly. Administering it slowly (a) would be ineffective. A central IV site is preferred (c), and hypotension (not hypertension) is a potential side effect (d).
