A nurse is preparing to measure a client's level of oxygen saturation and observes edema of both hands and thickened toenails. The nurse should apply the pulse oximeter probe to which of the following locations?

Finger

Skin fold

Toe

Earlobe

Answer and Explanation

The Correct Answer is D

A. Applying the pulse oximeter to a finger may not be ideal due to edema, which can affect the accuracy of the reading.

B. Using a skin fold is not a typical location for pulse oximetry and may not provide accurate readings.

C. Applying the probe to a toe may be less effective if the toenails are thickened, potentially affecting blood flow to that area and the accuracy of the reading.

D. The earlobe is a suitable alternative for measuring oxygen saturation, particularly in cases where peripheral sites (like fingers or toes) are compromised.
