W ITH RATIONALES ALREADY GRADEDA+.
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 ANSWERS -Unreliable; supplementary oxygen should be
administered

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 - CORRECT ANSWERS -Septic shock
