Question

A client is admitted with a diagnosis of myocardial infarction (MI). The client is complaining of chest pain. The nurse knows that pain related to an MI is due to

A) Insufficient oxygenation of the cardiac muscle
B) Potential circulatory overload
C) Left ventricular overload
D) Electrolyte imbalance

Answer 1

Pain related to a myocardial infarction (MI) is due to insufficient oxygenation of the cardiac muscle.

Step-by-step explanation:

Pain related to a myocardial infarction (MI), or heart attack, is due to insufficient oxygenation of the cardiac muscle. During an MI, there is a lack of blood flow and oxygen to a region of the heart, leading to the death of myocardial cells. This lack of oxygen causes chest pain and pressure, known as angina pectoris. The pain may radiate to the left arm in males, but not in females.
