A home health nurse is teaching a client who has heart failure. Which of the following responses should the nurse identify as an indication that the client understands the teaching?

Rationale: A. "I can have a total of 4 grams of sodium each day." For clients with heart failure, sodium intake is typically restricted to 2 grams per day to prevent fluid retention and exacerbation of symptoms. 4 grams per day exceeds the recommended. B. "I will weigh myself at different times of the day to monitor fluid retention." The client should weigh themselves at the same time each day, ideally in the morning after voiding. Weighing at different times can lead to inconsistencies. C. "I should be able to have a conversation while exercising." Clients with heart failure are encouraged to exercise at a moderate level that allows them to converse comfortably, which helps ensure they are not overexerting themselves and risking heart failure exacerbation. D. "I should take ibuprofen for a headache." Ibuprofen is contraindicated for clients with heart failure because it can cause fluid retention and negatively impact kidney function. Acetaminophen is a safer alternative for pain relief in these clients.
