AHA PALS Exam Complete Questions and Guide
Answers, 100% Verified Graded A+
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:
Answer: Unreliable; supplemen- tary oxygen should be administered
2. 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. 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 pres- sure?
A. Hypotensive
B. Normal
C. Hypertensive
D. Compensated:
Answer: Hypotensive
4. 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:
Answer: Respectfully ask the team leader to clarify the dose
5. 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:
Answer: Inadequate oxygenation and/or ventilation
6. 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:
Answer: Lower airway obstruction
7. 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:
Answer: Control of breathing
8. 8. What abnormality is most likely to be present in children with acute respi- ratory
distress caused by lung tissue disease?
A. Decreased oxygen saturation
B. Stridor
C. Normal respiratory rate
D. Decreased respiratory effort:
Answer: Decreased oxygen saturation
