Final answer:
In the case of acute decompensated heart failure with dyspnea at rest, the nurse anticipates administration of medications like diuretics, vasodilators, or positive inotropes to stabilize the patient's condition.
Step-by-step explanation:
The patient is admitted to the ICU with acute decompensated heart failure (HF) with dyspnea at rest. In such a critical care setting, the nurse would anticipate administration of medications that can rapidly reduce the symptoms and stabilize the patient's condition. Likely options include a diuretic such as furosemide to reduce fluid overload, as well as vasodilators like nitroglycerin or positive inotropes, such as dobutamine, to improve heart function. However, specific treatment may vary based on the patient's individual circumstances and underlying causes of their HF exacerbation.
