Answer to Question 1

A
Feedback:
Isoproterenol has a duration of action lasting 1 to 2 minutes with immediate onset of action. Dopamine acts as long as the drug is infusing with peak action 10 minutes after initiating the infusion. Phenylephrine's duration of action is 15 to 20 minutes. Ephedrine's duration of action will depend on how the drug is administered as it could be given intramuscularly, subcutaneously, IV, or orally, but no matter by what route it is administered, the duration of action is longer than 1 to 2 minutes.

Answer to Question 2

A, B, C, E
Feedback:
The adverse effects caused by barbiturates are more severe than those associated with other, newer sedatives/hypnotics. For this reason, barbiturates are no longer considered the mainstay for the treatment of anxiety. In addition, the development of physical tolerance and psychological dependence is more likely with the barbiturates than with other anxiolytics. The most common adverse effects are related to central nervous system (CNS) depression. Hypersensitivity reactions to barbiturates are sometimes fatal.
