Answer to Question 1
ANS: B
Beta blockers cause blockade of cardiac beta1 receptors, which can result in reduced atrioventricular conduction.
Two different medications are not generally needed to improve a hypertensive crisis.
The dilemma is the hypertensive crisis, which may lead to AV block, not the reflex tachycardia.
Cough is not a side effect of this beta blocker and does not contribute to a cardiac dysrhythmia; this would be the least concern of the scenario.
Answer to Question 2
ANS: A
African American patients who have type 1 diabetes and proteinuria should be treated with ACE inhibitors and diuretics.
Diuretics and calcium antagonists are not the preferred treatment for African Americans with comorbid conditions.
Beta blockers are less effective in African American patients than in Caucasian patients.
ACE inhibitors and beta blockers are not the preferred combination therapy for African Americans with comorbid conditions.
