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 - Correct
Answer Unreliable; supplementary oxygen should be administered

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?
