Question 1 of 5
A nurse is preparing to measure a client's oxygen saturation and notes edema of the client's hands and thickened toenails. The nurse should apply the pulse oximeter probe to which of the following locations?
Correct Answer: B
Rationale: The correct answer is B: Earlobe. The nurse should apply the pulse oximeter probe to the earlobe in this scenario because the client's hands have edema, making finger placement less reliable for accurate readings. Thickened toenails also suggest poor circulation in the toes, making toe placement less accurate. The earlobe provides a good peripheral site for accurate oxygen saturation measurement, as it has good blood flow and is less affected by edema or circulation issues. Placing the probe on the skin fold may lead to erroneous readings due to variations in skin thickness and perfusion.
Therefore, the earlobe is the most suitable and reliable location for obtaining an accurate oxygen saturation measurement in this situation.
