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
