AHA PALS Practice Exam 2025 Updated Questions and Verified Answers
1. 1. A 5-year-old child presents with lethargy, increased work oƒ 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 oƒ 165/min. The pulse oximeter displays an oxygen saturation oƒ 95% and a pulse
rate oƒ 93/min. On the basis oƒ this inƒormation, which oƒ the ƒollowing provides the best
interpretation oƒ the oxygen saturation oƒ 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; sup- plementary
oxygen should be administered

than 2 seconds. What is the child's most likely condition?
A. Septic shock
