Answer to Question 1

A
Feedback:
Bisoprolol reduces the workload of the heart and decreases myocardial oxygen demand by decreasing heart rate and the force of myocardial contractions. It does not prolong the QT interval or shorten the time required for repolarization.

Answer to Question 2

A
Feedback:
Intravenous diazepam (Valium) is administered intravenously to decrease seizure activity and has a 1- to 5-minute onset of action. Diazepam (Valium) decreases seizure activity in less than 7 to 10 minutes. Diazepam (Valium) should decrease seizure activity in less than 10 minutes. Diazepam (Valium) will take more than 1 minute to begin working.
