The nurse is performing pain assessment on a patient admitted for evaluation of angina. Which type of angina is precipitated by physical exertion and is relieved by rest?
 
  a. Chronic stable
  b. Nocturnal
  c. Unstable
  d. Variant

Question 2

How do beta-adrenergic blocking agents reduce myocardial oxygen demand?
 
  a. By inhibiting the stimulation of norepinephrine and epinephrine
  b. By increasing the production of dopamine and acetylcholine
  c. By delaying the destruction of acetylcholinesteras e and cholinesterase
  d. By enhancing the sensitivity of alpha receptors and beta receptors

Answer to Question 1

ANS: A
Chronic stable angina is precipitated by physical exertion or stress, lasts only a few minutes, and is relieved by rest or nitroglycerin. Nocturnal is not a designated classification. Unstable angina is unpredictable. Variant angina occurs at rest.

Answer to Question 2

ANS: A
Beta-adrenergic blocking agents prevent the stimulation of epinephrine and norepinephrine, which normally increase heart rate. Dopamine and acetylcholine are not beta-adrenergic neurotransmitters. Beta blockers do not delay the destruction of these enzymes. Beta blockers do not enhance the sensitivity of alpha adrenergic and beta receptor sites.
