Answer to Question 1

A
Feedback:
Clemastine blocks the effects of histamine at the histamine-1 receptor sites, decreasing the allergic response. It is prescribed to treat allergic rhinitis. Antiarrhythmic medications are used to treat atrial and ventricular dysrhythmias. Beta-hydroxy-beta-methylglutaryl coenzyme A reductase inhibitors are used to lower blood cholesterol by competitively inhibiting the rate-limiting enzyme in the liver. Beta-adrenergic agents lead to bronchodilation and stimulate beta2-adrenergic receptors in the smooth muscle of the bronchi and bronchioles.

Answer to Question 2

D
Feedback:
Tizanidine has been associated with hypotension, which could be a safety risk especially if the patient is also taking an antihypertensive drug. Constipation, dry mouth, and fatigue are common adverse effects that do not pose a safety risk.
