Answer to Question 1

B
Feedback:
The calcium channel blockers available in immediate-release and sustained-release forms that are used in treating hypertension include amlodipine (Norvasc), felodipine (Plendil), isradipine (DynaCirc, DynaCirc CR), and nicardipine (Cardene, Cardene SR). Other calcium channel blockers are safe and effective for this use only if they are given as sustained-release or extended-release preparations. These include diltiazem (Cardizem, Dilacor CR), nifedipine (Procardia XL), nisoldipine (Sular), and verapamil (Calan SR). Aliskiren (Tekturna) is a renin inhibitor. Atenolol (Tenormin) and Metoprolol (Lopressor) are beta-blockers, not calcium channel blockers.

Answer to Question 2

A
Feedback:
Patients present with the signs and symptoms of acute infection, including fever, malaise, myalgia, arthralgia, and a purulent, productive cough. A patient with bronchiectasis would not present with pulmonary hypertension, chest deformity, or chest pain related to lack of oxygen to the heart.
