An older adult client with a history of heart failure (HF) is brought to the clinic by a family member. Which finding(s) confirm(s) to the nurse that the client is experiencing an exacerbation of the HF? Select all that apply.

A. Peripheral edema: Peripheral edema is a classic sign of right-sided heart failure due to venous congestion. When the heart cannot pump effectively, there is increased fluid volume and pressure in the veins causing fluid to leak into the surrounding tissues fluid accumulates in dependent areas like the legs and ankles, especially in older adults with chronic heart failure.B. Dyspnea: Dyspnea is a key indicator of left-sided heart failure, resulting from pulmonary congestion. As the left ventricle fails to pump efficiently, fluid backs up into the lungs, impairing gas exchange and causing shortness of breath during exertion or even at rest. Dyspnea can occur at rest or with exertion and may worsen when lying flat (orthopnea) or during the night (paroxysmal nocturnal dyspnea).C. Jugular venous distension: JVD occurs when elevated right atrial pressure causes the jugular veins to become distended. It is a significant clinical finding in right-sided heart failure and reflects systemic fluid overload and impaired venous return.D. Intercostal retractions: Intercostal retractions are a sign of increased respiratory effort, indicating that the patient is struggling to breathe. In heart failure exacerbation, pulmonary congestion increases the work of breathing, leading to respiratory distress and visible use of accessory muscles.E. Headaches: Headaches are not typically associated with heart failure and are not considered a reliable indicator of an exacerbation. They may be due to other causes such as hypertension, stress, or neurological issues and require separate evaluation.
