A nurse is educating a student on modifiable risk factors of atherosclerosis. Which of the following statements should the nurse include in the teaching? (Select all that apply.)

Rationale:

A. Ejection fraction is typically assessed using echocardiography or other imaging modalities, not electrocardiography.

B. Visualizing the flow of blood within the heart is typically done using imaging modalities such as echocardiography or cardiac catheterization, not electrocardiography.

C. The client's position during an electrocardiogram is usually supine, not specifically on the left side.

D. Electrocardiography is primarily used to detect abnormal rhythms of the heart, such as atrial fibrillation, ventricular tachycardia, or heart block.

Rationale:

A. Completing an electrocardiogram (ECG) is a priority in assessing a patient with chest pain to evaluate for signs of acute myocardial infarction or other cardiac abnormalities.

B. Obtaining a C-reactive protein level may be useful in certain situations to assess inflammation, but it is not a priority in the acute management of chest pain.

C. Administering an anti-hypertensive medication is not a priority unless the patient's blood pressure is significantly elevated and causing acute symptoms.

D. Completing an echocardiogram may be indicated later in the assessment process but is not typically performed immediately in the emergency room for evaluation of chest pain.
