Answer to Question 1

ANS: D
The patient is clearly in a state of extreme, uncontrolled anxiety. Benzodiazepines are the drug of choice for acute episodes of anxiety because of their rapid onset of action. Benzodiazepines do not have a very short half-life. Benzodiazepines are associated with physical dependence. Benzodiazepines do not cure generalized anxiety, nor do any other drugs.

Answer to Question 2

ANS: A
Benzodiazepines are first-choice drugs for anxiety, and alprazolam and lorazepam are prescribed most often. Selective serotonin reuptake inhibitors (SSRIs) are the first-line drugs for the treatment of OCD. Panic disorder is treated with any of the three classes of antidepressants: SSRIs, tricyclic antidepressants (TCAs), and monoamine oxidase inhibitors (MAOIs). Research has not shown any drug to be effective in the treatment of PTSD, although two SSRIs have been approved for use for this disorder.
