Answer to Question 1

ANS: D
Samples for trough levels should be drawn just prior to the next dose (when divided daily doses are used) or 1 hour before the next dose (when a single daily dose is used).

Answer to Question 2

ANS: B
Neuromuscular blockade can be reversed with calcium. IV infusion of calcium salt (calcium gluconate) is the treatment of choice.
Epinephrine is not indicated for aminoglycoside toxicity; in fact, aminoglycoside toxicity is not apparent.
Decadron would not reverse the current condition.
Nothing indicates that the patient requires magnesium sulfate.
