Answer to Question 1
ANS: B
Orthostatic hypotension can occur particularly at the initiation of therapy. Patients should be encouraged to change positions slowly. Symptoms generally will resolve as the patient becomes used to the medication. Postural hypotension is not a therapeutic effect and is not a precursor to a hypertensive crisis. Postural hypotension is an adverse effect with vasodilator therapy.
Answer to Question 2
ANS: C
Sudden discontinuation of beta-adrenergic therapy has caused an exacerbation of anginal symptoms, resulting in cases of myocardial infarction. Postural hypotension occurs with the onset of treatment. Edema and confusion are not precipitated by cessation of treatment with beta blockers.
