A nurse is planning to obtain a client's oxygen saturation. Which of the following might influence the result of this test?
The client has a fever.
The client has an elevated hemoglobin level.
The client is wearing a ring.
The client is wearing nail polish.
The Correct Answer is D
Rationale:
A. A fever may influence the result of an oxygen saturation test but is not a direct factor.
B. An elevated hemoglobin level is unlikely to influence the result of an oxygen saturation test.
C. Wearing a ring is unlikely to influence the result of an oxygen saturation test.
D. Wearing nail polish can interfere with the accuracy of pulse oximetry readings by causing an inaccurate reflection of light, leading to a falsely low oxygen saturation reading.

Correct Answer is B
Explanation
A. Cleaning around the stoma with a moisturizing soap is not recommended. Moisturizing soaps can leave a residue that may interfere with the adhesion of the skin barrier. The client should use warm water or a mild, non-moisturizing soap to clean the area.
B. Pressing on the skin barrier for 30 seconds to ensure that it adheres is correct. This technique helps secure the barrier to the skin, creating a good seal and reducing the risk of leaks.
C. Cutting an opening in the skin barrier that is 1/2 inch larger than the stoma is incorrect. The opening should be about 1/8 inch larger than the stoma to ensure a snug fit, which helps protect the surrounding skin from exposure to effluent.
D. Applying a thin layer of talc powder around the stoma before placing the appliance is not appropriate. Powders are typically used to manage irritated skin but should be avoided unless specifically recommended by a healthcare provider. Overuse can interfere with the appliance’s adhesion.
