Correct answer: D — Refer to the prescriber for dose and timing review and counsel on postural symptoms

Alpha-blockers can cause postural hypotension, particularly after initiation or dose escalation. The best answer addresses the key safety, legal or pharmaceutical care issue in the vignette. The other options would either delay appropriate care, create a new risk, or fail to resolve the issue. This is consistent with the cited UK reference for safe pharmacy practice.
