AHA PALS Practice exam (100 out of 100) Questions and
Answers (Download To Score An A)
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
D. Decreased respiratory effort
Decreased oxygen saturation
9. An alert 2-year-old child with an increased work of breathing and pink color is being evaluated. Heart
rate is 110/min, and respiratory rate is 30/min. What would best describe this patient's condition? A.
Respiratory distress
B. Respiratory arrest
C. Respiratory failure
D. Disordered control of breathing
Respiratory distress
10. The parents of a 7-year-old child who is undergoing chemotherapy report that the child has been
febrile and has not been feeling well, with recent onset of lethargy. Assessment reveals the following:
The child is difficult to arouse, with pale color. The child's heart rate is 160/min, respiratory rate is
30/min, blood pressure is 76/45 mm Hg, capillary refill time is 5 to 6 seconds, and temperature is 103°F
(39.4°C). What is the most appropriate intervention?
