"a client is admitted to the visiting nurse service for assessment and follow-up after being discharged from the hospital with new-onset heart failure (hf). the nurse teaches the client about the dietary restrictions required with hf. which statement by the client indicates that further teaching is needed?

"I'm going to have a ham and cheese sandwich and potato chips for lunch."

Explanation:

Diet for patients with heart failure is very important to prevent and remedy the establishment of this situation. The diet of these patients should be rich in fruits, vegetables, legumes, cheeses and lean meats. These patients should avoid canned processed foods (such as cheese and ham). Salt should be strictly avoided because these patients need to reduce fluid accumulation in the environment, so the patient should cut foods that have too much salt in their composition such as ham and chips. For this reason, we can say that a patient with heart failure who wants to eat a cheese and ham sandwich and a portion of chips is not well informed about his situation and needs further explanation.
