NCLEX Heart Failure Practice Test

Guideline-directed therapy in heart failure aims to stabilize the patient by reducing fluid overload and improving cardiac function. A positive response is shown when the patient has relief from congestion symptoms, stable vitals, weight loss from diuresis, and better exercise tolerance, with no new or worsening signs of heart failure. This pattern indicates that treatment is effectively improving hemodynamics and functional capacity. In contrast, worsening dyspnea and edema with unstable vitals points to decompensation; increased edema alone signals ongoing fluid accumulation; and no change in exercise tolerance suggests little to no functional improvement.
