The nurse is educating her patient on the pumping efficacy of the heart.
The nurse knows that the patient understands the teaching when the patient states:

Choice A rationale:

Encouraging range-of-motion exercises of the foot is not advisable because it can cause further injury to the ankle.

Choice B rationale:

Providing the client with a light snack is not directly related to the care of an ankle injury.

Choice C rationale:

Applying ice to the ankle can help reduce swelling and pain.

Choice D rationale:

Applying a compression bandage can help reduce swelling.

Choice E rationale:

Elevating the foot can help reduce swelling by promoting venous return.

The correct answers are Choice B: "I must stop smoking.", Choice C: "I am limiting my intake of fast foods.", and Choice E: "I need to monitor my weight."

Choice A rationale:

Stopping alcohol consumption can have various health benefits, but moderate alcohol consumption is not a primary risk factor for coronary artery disease. Instead, excessive drinking is more concerning.

Choice B rationale:

Smoking is a significant risk factor for coronary artery disease. Quitting smoking greatly reduces the risk and improves overall cardiovascular health.

Choice C rationale:

Limiting fast food intake is an important dietary change, as fast foods are often high in unhealthy fats, salt, and calories, which can contribute to coronary artery disease.

Choice D rationale:

The statement "I should lower my HDL cholesterol level" is incorrect. HDL cholesterol is considered "good" cholesterol and helps to protect against heart disease. Therefore, lowering HDL cholesterol would not be beneficial.

Choice E rationale:

Monitoring and maintaining a healthy weight is crucial for reducing the risk of coronary artery disease. Excess weight, particularly around the abdomen, is a known risk factor.
