Correct Answer is D
Explanation
Choice A rationale
While feeling depressed is a significant concern, it is not the highest priority in the context of systemic lupus erythematosus (SLE). Depression should be addressed, but it does not pose an immediate threat to the client’s physical health.
Choice B rationale
Joint pain in hands and knees is a common symptom of SLE but is not the highest priority. It indicates inflammation but does not pose an immediate risk to the client’s overall health.
Choice C rationale
A dry, raised rash on the face, often referred to as a “butterfly rash,” is a characteristic symptom of SLE. However, it is not the highest priority to report as it does not pose an immediate threat.
Choice D rationale
Presence of peripheral edema is the highest priority to report because it can indicate kidney involvement, which is a serious complication of SLE. Kidney damage can lead to significant health issues and requires immediate attention.
