- A. Acid rebound
- B. Neurotoxicity
- C. Blurred vision
- D. Bone softening
Correct Answer: C
Rationale: The nurse should monitor the client for blurred vision as an adverse reaction to the trimethobenzamide hydrochloride (Tigan). The nurse need not monitor the client for acid rebound, neurotoxicity, and bone softening as they are not adverse reactions to trimethobenzamide hydrochloride (Tigan). Acid rebound is an adverse reaction to calcium carbonate. Neurotoxicity and bone softening are adverse reactions to aluminum carbonate gel.
