A 51-year-old male is at the health clinic for an annual physical exam. After walking from the car to the clinic, he developed substernal pain.
 
  He also reported discomfort in his left shoulder and his jaw, lasting 2-3 minutes and then subsid-ing with rest. He indicates that this has occurred frequently over the past few months with similar exertion. The nurse suspects he is most likely experiencing:
  a. Stable angina
  b. Unstable angina
  c. Prinzmetal angina
  d. Myocardial infarction (MI)

Question 2

A 75-year-old male has severe chest pain and dials 911. Based upon the lab findings indicating a patient has elevated levels of cardiac troponins I and T, the nurse suspects which of the following has occurred?
 
  a. Raynaud disease
  b. Myocardial infarction (MI)
  c. Orthostatic hypotension
  d. Angina

Answer to Question 1

ANS: A
Stable angina is associated with activity and subsides with rest. Unstable angina is a form of acute coronary syndrome that results from reversible myocardial ischemia and occurs at rest. Chest pain that occurs at rest and at night is descriptive of Prinzmetal angina. MI pain does not subside with rest.

Answer to Question 2

ANS: B
The diagnosis of acute MI is made on the basis of serial cardiac biomarker alterations. The cardi-ac troponins (troponins I and T) are the most specific indicators of MI. Elevated troponins I and T are indicative of MI, not Raynaud disease, orthostatic hypotension, or angina
