A patient has inadequate stroke volume related to decreased preload. Which treatment does the nurse prepare to administer?
Chest physiotherapy
Diuretics
Vasodilators
Intravenous (IV) fluids
The Correct Answer is D
A. Chest physiotherapy is used to mobilize secretions and improve lung function, not specifically for increasing stroke volume or preload.
B. Diuretics would decrease preload by removing excess fluid, which is counterproductive in a patient with inadequate stroke volume related to decreased preload.
C. Vasodilators can further decrease preload and are not appropriate in this scenario where preload needs to be increased.
D. Intravenous (IV) fluids are administered to increase preload and improve stroke volume by enhancing the circulating blood volume.
