An elderly patient presents with a right-sided headache and acute loss of vision on the same side. Tenderness is noted to the right temporal region as well as to the scalp. To obtain a definitive diagnosis, the nurse practitioner will order:

Correct Answer: C

Rationale: The correct answer is C: Temporal artery biopsy. This is the gold standard for diagnosing giant cell arteritis, which presents with symptoms such as headache, vision loss, and tenderness to the temporal region and scalp. The biopsy will show characteristic inflammatory changes in the artery wall. A: ESR and B: CRP are nonspecific markers of inflammation and can be elevated in various conditions, including giant cell arteritis, but they do not provide a definitive diagnosis. D: CT scan of the head may show signs of inflammation in the temporal artery, but it is less sensitive than a biopsy for diagnosing giant cell arteritis.

Correct Answer: D

Rationale: The correct answer is D: helping the patient focus on the here and now. This is appropriate for depersonalization disorder as it helps the patient ground themselves in reality and reduce dissociative symptoms. Encouraging meditation (A) may exacerbate dissociation by further disconnecting the patient from reality. Administering an anxiolytic medication (B) may provide temporary relief but does not address the underlying issue. Helping the patient visualize a pleasant scene (C) may be soothing but may not be effective in addressing the dissociative symptoms.
