First drug of choice for acute pulmonary edema is
**Core Concept**
The first-line management of acute pulmonary edema involves pharmacological interventions to rapidly alleviate symptoms and improve oxygenation. **Nitrates** are a cornerstone in the treatment of acute pulmonary edema, as they help to reduce preload and afterload, thereby decreasing the workload on the heart and improving lung function.
**Why the Correct Answer is Right**
The correct answer is **furosemide**. Furosemide is a loop diuretic that is commonly used to treat acute pulmonary edema by promoting the excretion of sodium and water, thereby reducing fluid overload and congestion in the lungs. This rapid diuresis helps to improve lung compliance, reduce pulmonary pressure, and increase oxygenation. Furosemide also has a rapid onset of action, making it an ideal choice for acute management.
**Why Each Wrong Option is Incorrect**
**Option A:** This option is incorrect because **morphine** is not a first-line treatment for acute pulmonary edema. While it may provide some relief from dyspnea, it does not address the underlying pathophysiology of the condition.
**Option B:** This option is incorrect because **beta-blockers** are actually contraindicated in acute pulmonary edema, as they can worsen cardiac function and increase pulmonary congestion.
**Option C:** This option is incorrect because **ACE inhibitors** are not typically used as first-line treatment for acute pulmonary edema. They are more commonly used for long-term management of heart failure.
**Clinical Pearl / High-Yield Fact**
It's essential to remember that the initial management of acute pulmonary edema involves rapid assessment and stabilization of the patient, followed by prompt initiation of pharmacological therapy. In addition to furosemide, other important interventions include oxygen therapy, non-invasive ventilation, and, if necessary, intubation and mechanical ventilation.
**Correct Answer:** F. Furosemide
