What is a common indication of worsening heart failure a nurse should teach a client to recognize?

Experiencing a persistent cough is recognized as a common indication of worsening heart failure. In heart failure, the heart's ability to pump blood effectively is compromised, leading to fluid buildup in the lungs—a condition known as pulmonary congestion or pulmonary edema. This fluid accumulation can irritate the airways, resulting in a chronic, often wet cough as the body attempts to clear this fluid buildup.

Additionally, this cough may be accompanied by other symptoms, such as shortness of breath, difficulty breathing when lying flat (orthopnea), or fatigue. Teaching clients to recognize these signs empowers them to seek timely medical attention, which is crucial for managing heart failure effectively.

In contrast, increased physical activity tolerance, enhanced appetite, and regular bowel movements are typically not associated with the worsening of heart failure. These signs could be seen as positive indicators of health and stability, whereas a persistent cough serves as a warning signal that the condition may be deteriorating.
