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
