A nurse is educating clients about breast cancer at a community health event. Which of the following statements should the nurse include in the training?

Choice A rationale
Coronary arteries decrease in diameter leading to insufficient blood, oxygen, and nutrients reaching the heart muscle. This is correct because atherosclerosis, which is the buildup of plaque in the coronary arteries, causes the arteries to narrow. This narrowing reduces blood flow to the heart muscle, leading to ischemia and the manifestations of coronary artery disease, such as angina and myocardial infarction.
Choice B rationale
Manifestations occur due to dilation of coronary arteries with increased blood flow causing increased pressure. This is incorrect because the primary issue in coronary artery disease is the narrowing of the arteries, not their dilation. Increased blood flow and pressure are not typical causes of the manifestations of coronary artery disease.
Choice C rationale

Coronary arteries become more elastic causing the arteries to stretch as individuals age causing the heart not to receive enough oxygen. This is incorrect because the problem in coronary artery disease is not increased elasticity but rather the loss of elasticity and the buildup of plaque that narrows the arteries. As people age, the arteries tend to become less elastic, not more.
Choice D rationale
The heart and the coronary arteries weaken, leading to poor perfusion and resulting in angina. This is incorrect because the primary issue in coronary artery disease is the narrowing of the coronary arteries due to plaque buildup, not the weakening of the heart and arteries. While poor perfusion does result in angina, it is due to the narrowed arteries rather than weakened structures.

Choice A rationale
The client has an increased risk for bleeding. Cisplatin is a chemotherapy drug that can cause myelosuppression, leading to a decrease in platelets (thrombocytopenia). However, the client’s platelet count is 170,000/mm³, which is within the normal range (150,000-450,000/mm³).
Therefore, the client does not have an increased risk for bleeding based on the current CBC results.
Choice B rationale
The client should receive an erythropoiesis stimulating agent. Cisplatin can cause anemia due to myelosuppression, which would be indicated by a low hemoglobin (Hgb) and hematocrit (Hct). However, the client’s Hgb is 12.1 g/dL and Hct is 36.5%, both of which are within normal limits (Hgb: 12-16 g/dL for females, Hct: 36-48% for females). Therefore, there is no immediate need for an erythropoiesis stimulating agent based on the current CBC results.
Choice C rationale
The client should receive a diet with increased protein. While a high-protein diet can be beneficial for cancer patients to help maintain muscle mass and support recovery, the CBC results do not indicate a specific need for increased protein intake. The client’s albumin level is 4.5 g/dL, which is within the normal range (3.5-5.0 g/dL), indicating adequate protein status.
Choice D rationale
The client has an increased risk of infection. Cisplatin can cause neutropenia, a condition characterized by a low white blood cell (WBC) count, which increases the risk of infection. The client’s WBC count is 1,400/mm³, which is significantly below the normal range (4,000- 11,000/mm³). This indicates severe neutropenia, putting the client at a high risk for infections. Therefore, it is crucial for the nurse to consider infection prevention measures for this client.
