The nurse is explaining the difference between the cause of acute coronary syndrome (ACS) and a myocardial infarction to a client and family. What should the nurse teach about these health problems?
 
  1. ACS pain radiates to the jaw.
  2. Myocardial infarction is characterized as gas-like pain.
  3. The pain from ACS often occurs at rest or upon arising.
  4. Pain from a myocardial infarction begins abruptly and is related to exercise.

Question 2

A client with heart failure is diagnosed with a low ejection fraction. What aspects of the client's heart function should the nurse realize contributed to this poor finding? (Select all that apply.)
 
  1. Preload
  2. Afterload
  3. Contractility
  4. Ventricular response
  5. Sinoatrial node firing

Answer to Question 1

Answer: 3

1. Pain from a myocardial infarction radiates to the jaw.
2. Clients describe the pain of a myocardial infarction as crushing.
3. Pain from ACS is often noted at rest or upon arising.
4. Pain from a myocardial infarction is abrupt and unrelated to exercise.

Answer to Question 2

Answer: 1, 2, 3

1. The ejection fraction, or the percentage of blood in the ventricle that is ejected with each contraction, is affected by preload.
2. The ejection fraction, or the percentage of blood in the ventricle that is ejected with each contraction, is affected by afterload.
3. The ejection fraction, or the percentage of blood in the ventricle that is ejected with each contraction, is affected by contractility.
4. Ventricular response does not affect the ejection fraction.
5. Sinoatrial node firing does not affect the ejection fraction.
