A nurse provides teaching to a patient with angina who also has type 2 diabetes mellitus, asthma, and hypertension. Which statement by the patient indicates a need for further teaching?
 
  a. An ACE inhibitor, in addition to nitroglycerin, will lower my risk of cardiovascular death.
  b. Beta blockers can help control hypertension.
  c. I should begin regular aerobic exercise.
  d. Long-acting, slow-release calcium channel blockers can help with anginal pain.

Question 2

A nursing student asks a nurse how beta blockers increase the oxygen supply to the heart in the treatment of anginal pain. The nurse tells the student that beta blockers:
 
  a. dilate arterioles to improve myocardial circulation.
  b. improve cardiac contractility, which makes the heart more efficient.

Answer to Question 1

ANS: B
Beta blockers can be used for angina in most patients but are contraindicated in patients with asthma, because they cause bronchoconstriction . ACE inhibitors help reduce the risk of death in patients with hypertension. Regular aerobic exercise is recommended to control weight and improve cardiovascular function. Long-acting, slow-release CCBs are recommended for patients who have coexisting type 2 diabetes.

Answer to Question 2

ANS: D
Beta blockers increase the time the heart is in diastole, which increases the time during which blood flows through the myocardial vessels, allowing more oxygen to reach the heart. Beta blockers do not dilate arterioles. They do not increase cardiac contractility; they decrease it, which reduces the cardiac oxygen demand. They do not increase arterial pressure, which would increase the cardiac oxygen demand.
