Answer: C - The appropriate and initial action of the nurse is to instruct the client to discontinue taking the organic diet pills. Verapamil is a calcium channel blocker that prevents the occurrence of angina by dilating the coronary and peripheral arteries and decreasing myocardial contractility and conduction velocity. If the client is taking diet pills, this could stimulate the heart and constrict the blood vessels, resulting in angina. If the client is trying to lose weight, the nurse should provide guidelines on proper diet and exercise.
