Correct answer: C — Advise postural precautions and refer to the prescriber for dose review

Alpha-blockers can cause postural hypotension and falls, particularly after initiation or dose escalation. In this vignette, "Advise postural precautions and refer to the prescriber for dose review" is the safest single best answer. The other options are less appropriate because they miss the key clinical risk, conflict with UK medicines guidance, or delay needed review.
