Answer to Question 1

D
Feedback:
Of the nonselective alpha-adrenergic blocking agents, only phentolamine is still used today. Metoprolol is a beta1-selective adrenergic blocking agent. Timolol and propranolol are nonselective beta-adrenergic blocking agents.

Answer to Question 2

C
Feedback:
This disorder, which seems to have a very strong genetic association, may reflect a fundamental biochemical abnormality. Mental disorders are now thought to be caused by some inherent dysfunction within the brain that leads to abnormal thought processes and responses. Schizophrenia is not caused by pain, childhood trauma, or seizure activity.
