Answer to Question 1

Ans: A, B, E
Feedback:
Signs and symptoms of neurotoxicity include numbness, skin tingling, circumoral (around the mouth) paresthesia, peripheral paresthesia, tremors, muscle twitching, convulsions, muscle weakness, and neuromuscular blockade (acute muscular paralysis and apnea). Ringing in the ears and vertigo would suggest ototoxicity.

Answer to Question 2

Ans: C
Feedback:
Kanamycin and neomycin are used before surgery to reduce intestinal bacteria. It is thought that this reduces the possibility of abdominal infection that may occur after surgery on the bowel. By destroying bacteria in the gut and washing it out with laxatives or enemas, the surgical area becomes as clean as possible before the operation. The drug is not used to control an infection preoperatively. It does help to reduce blood ammonia levels with hepatic coma, but this is not the reason for its use with this patient. The drug has no effect on preventing blood clots postoperatively.
