Answer to Question 1
ANS: A
Beta blockers are often added to drug regimens to treat reflex tachycardia, which is a common side effect of lowering blood pressure, caused by the baroreceptor reflex. The patient's blood pressure is responding to the medications, but the tachycardia warrants treatment. Reminding the patient to move slowly from sitting to standing is appropriate with any blood pressure medication, but this patient has reflex tachycardia, which must be treated. An electrocardiogram is not indicated.
Answer to Question 2
ANS: C
Diagnosis of hypertension should be based on several blood pressure readings, not just one. High readings should be confirmed in the contralateral arm. Low-sodium diets are indicated for patients with confirmed hypertension. An electrocardiogram and blood tests are indicated for patients with confirmed hypertension to rule out primary causes. Thiazide diuretics are first-line drugs for confirmed hypertension.
