For a client with systolic heart failure, what describes the desired effect of medication that decreases preload?

In the context of systolic heart failure, medications that decrease preload are targeted to reduce the volume of blood returning to the heart, specifically to the right side. This reduction in venous return helps to alleviate the workload on the heart, allowing it to pump more effectively without being overwhelmed by excess volume.

Reducing preload can lead to a decrease in congestion and improve the overall hemodynamic status of a patient with heart failure. Elevated preload often leads to increased pressure in the heart and lungs, which causes symptoms like shortness of breath and edema. By decreasing venous return to the right heart, the medication helps mitigate these symptoms and supports better heart function.

Other options may seem relevant but do not directly align with the goal of decreasing preload in the context of systolic heart failure. For instance, reducing heart rate may occur as a secondary effect but is not a direct desired outcome of preload-reducing medications. Similarly, increasing cardiac output is typically a goal of heart failure treatment, but preload reduction does not guarantee this outcome. Enhancing renal perfusion is important for managing heart failure but is not the primary effect of reducing preload.

Thus, the correct response captures the primary therapeutic goal of decreasing preload in heart failure management.
