Question

A nurse is evaluating a patients understanding after he was diagnosed with a myocardial infarction. Which of the following would indicate that the patient did not understand important information and needs additional teaching?

1) A heart attack is the same as a myocardial infarction (MI).
2) A heart attack causes tissue death and that part of the heart may not pump as well.
3) A heart attack in the anterior wall of the heart can be very serious because a large portion of the heart may not pump as well.
4) Angina always leads first to decreased blood flow to the heart muscle and then to tissue death.

Answer 1

Option 4 indicates a misunderstanding as angina doesn't always lead to tissue death. Option 1, 2, and 3 are correct statements about a heart attack (MI).

Step-by-step explanation:

The correct answer would be option 4: Angina always leads first to decreased blood flow to the heart muscle and then to tissue death. This statement is incorrect and indicates a misunderstanding of important information. Angina is chest pain or discomfort that occurs when the heart muscle doesn't receive enough oxygen-rich blood. It is a symptom of coronary artery disease but does not always lead to tissue death. Myocardial infarction (MI), or heart attack, occurs when blood flow to the heart muscle is completely blocked, leading to the death of cardiac muscle cells.

Option 1 is correct and indicates a good understanding, as a heart attack is indeed the same as a myocardial infarction. Option 2 is also correct, as a heart attack does cause tissue death, which can result in impaired heart function. Option 3 is correct as well because an anterior wall heart attack can be serious due to the large area of the heart affected.
