AHA PALS EXAM 2025
QUESTIONS AND 100%
CORRECT ANSWER VERSION 1
AND VERSION 2
Version 1
1. A 5-year-old child presents with lethargy, increased work of breathing, and
pale color. The primary assessment reveals that the airway is open and the
respiratory rate is 30/min, with crackles heard on auscultation. The cardiac
monitor shows sinus tachycardia at a rate of 165/min. The pulse oximeter
displays an oxygen saturation of 95% and a pulse rate of 93/min. On the
basis of this information, which of the following provides the best
interpretation of the oxygen saturation of 95% by pulse oximetry?
A. Reliable; no supplementary oxygen is indicated B. Reliable;
supplementary oxygen should be administered
C. Unreliable; no supplementary oxygen is indicated
D. Unreliable; supplementary oxygen should be administered
Unreliable; supplementary oxygen should be administered
2. A 3-year-old child was recently diagnosed with leukemia and has been
treated with chemotherapy. The child presents with lethargy and a high
fever. Heart rate is 195/min, respiratory rate is 36/min, blood pressure is
85/40 mm Hg, and capillary refill time is less than 2 seconds. What is the
child's most likely condition?
A. Septic shock
B. Hypovolemic shock
,C. Significant bradycardia
D. Cardiogenic shock
Septic shock
3. A 2-week-old infant presents with irritability and a history of poor feeding.
Blood pressure is 55/40 mm Hg. What term describes this infant's blood
pressure?
A. Hypotensive
B. Normal
C. Hypertensive
D. Compensated
Hypotensive
4. During a resuscitation attempt, the team leader orders an initial dose of
epinephrine at 0.1 mg/kg to be given 10. What should the team member do?
A. Administer the drug as ordered
B. Administer 0.01 mg/kg of epinephrine
C. Respectfully ask the team leader to clarify the dose
D. Refuse to administer the drug
Respectfully ask the team leader to clarify the dose
5. Which of the following is a characteristic of respiratory failure?
A. Inadequate oxygenation and/or ventilation
B. Hypotension
C. An increase in serum pH (alkalosis)
, D. Abnormal respiratory sounds
Inadequate oxygenation and/or ventilation
6. Which of the following is most likely to produce a prolonged expiratory
phase and wheezing?
A. Disordered control of breathing
B. Hypovolemic shock
C. Lower airway obstruction
D. Upper airway obstruction
Lower airway obstruction
7. A 4-year-old child presents with seizures and irregular respirations. The
seizures stopped a few minutes ago. Which of the following most likely to be
abnormal?
A. Vascular resistance
B. Pulse rate
C. Lung compliance
D. Control of breathing
Control of breathing
8. What abnormality is most likely to be present in children with acute
respiratory distress caused by lung tissue disease?
A. Decreased oxygen saturation
B. Stridor
C. Normal respiratory rate
