A nurse is reinforcing teaching to a client who has coronary artery disease. Which of the following statements should the nurse include in the teaching to explain the correlation between changes in the coronary arteries and manifestations that occur?
"Coronary arteries become more elastic causing the arteries to stretch as individuals age causing the heart not to receive enough oxygen."
"The heart and the coronary arteries weaken, leading to poor perfusion and resulting in angina."
"Manifestations occur due to dilation of coronary arteries with increased blood flow causing increased pressure."
"Coronary arteries decrease in diameter leading to insufficient blood, oxygen, and nutrients reaching the heart muscle."
The Correct Answer is D
A. While coronary arteries may change with age, the increased elasticity does not lead to insufficient oxygen; rather, it can affect their ability to respond to increased demand.
B. Weakening of the heart can contribute to heart failure but is not a direct explanation for how coronary artery disease causes angina.
C. Dilation of coronary arteries typically does not cause manifestations in coronary artery disease; instead, it is the narrowing (stenosis) that leads to issues.
D. Decreased diameter of the coronary arteries due to atherosclerosis is the primary issue in coronary artery disease, which leads to inadequate blood supply, oxygen, and nutrients to the heart muscle, causing symptoms like angina.

Correct Answer is B
Explanation
A. The right groin area is not the site of the procedure, so placing a sandbag here would not help control bleeding or pressure.
B. The sandbag should be placed over the left groin area where the femoral artery was accessed during the angiography. This helps apply pressure to prevent bleeding from the site and promote clot formation.
C. The right ankle is irrelevant to the procedure and would not require pressure.
D. Similarly, the left ankle has no relation to the femoral angiography site.
Correct Answer is A
Explanation
A. Dysphagia increases the risk of aspiration, especially when swallowing difficulties are present, making it essential to monitor for signs of aspiration.
B. Gastroesophageal reflux disease (GERD) is not directly related to dysphagia from a stroke.
C. Dumping syndrome occurs after certain types of gastric surgery and is not associated with dysphagia post-stroke.
D. Peptic ulcer disease is not a typical complication of dysphagia following a stroke.
