124) ANSWER
C) Hydroxyzine (Atarax)
RATIONALE
Hydroxyzine hydrochloride is an antihistamine
that is a competitive inhibitor of the H1 receptor. It is used to treat various
reactions that are mediated by histamine. It will decrease the pruritus
produced by the release of histamine. Cimetidine is an H2 histamine antagonist and these agents
are not effective against hypersensitivity reactions. Lorazepam is a
short-acting benzodiazepine that is indicated for anxiety. Bupivacaine is a
local anesthetic for nerve blocks. The core issue of the question is knowledge
of which drug relieves itching. Use specific drug knowledge and the process of
elimination to make a selection.
