The client has an elevated hemoglobin level.
The client is wearing a ring.
The client is wearing nail polish.
The Correct Answer is D

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 D
Explanation
Rationale:
A. Telling the nurse that permission from the risk manager is required to view the client's record is not accurate and may not address the situation appropriately.
B. Contacting facility security to remove the nurse from the unit is not necessary and may not address the situation appropriately.
C. Completing an incident report about the breach of confidentiality may be appropriate later if the situation escalates or if there is no resolution after speaking to the nurse. However, the immediate step is to address the breach directly.
D. Reminding the nurse that only staff caring for the client may access the client's record is the correct action. The nurse should remind the colleague that access to a client's medical record is restricted to those directly involved in their care. This respects patient confidentiality and complies with legal and ethical guidelines.
