AHA PALS Practice exam 2023 Questions with Correct Answers

• 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?

• Reliable; no supplementary oxygen is indicated B. Reliable; supplementary oxygen

should be administered

• Unreliable; no supplementary oxygen is indicated
• Unreliable; supplementary oxygen should be administered - Correct Answer

Unreliable; supplementary oxygen should be administered
