Final answer:
In the context of acute heart failure, the nurse should question the order for Carvedilol (Coreg), which is a beta blocker, because it has negative inotropic effects that could worsen the patient’s condition by decreasing the heart’s contractility.
Step-by-step explanation:
The medication that a nurse should question when treating a patient with acute heart failure is Carvedilol (Coreg), a beta blocker. Beta blockers work by blocking beta receptors, slowing down the heart rate (HR), and can cause a reduction in the strength of the heart’s contractions. Although beta blockers can improve cardiac function in certain chronic heart conditions, they are generally used with caution in the setting of acute heart failure due to the risk of exacerbating the condition by further decreasing cardiac output.
Carvedilol is known to have negative inotropic effects, which means it can decrease the force of the heart's contraction. Unlike Dobutamine (Dobutrex), Milrinone (Primacor), and Levosimendan (Simdax), which are positive inotropic agents that increase the strength of the heart's contractions, the use of Carvedilol could potentially worsen the patient’s acute heart failure by further reducing contractility.
