All of the following statements about nesiritide except
**Core Concept**
Nesiritide is a synthetic analog of human B-type natriuretic peptide (BNP) used in the treatment of decompensated heart failure. It has vasodilatory properties, reducing preload and afterload, and is administered intravenously.
**Why the Correct Answer is Right**
Nesiritide works by binding to the natriuretic peptide receptor, leading to increased cyclic guanosine monophosphate (cGMP) levels, which in turn cause smooth muscle relaxation, vasodilation, and decreased blood pressure. This mechanism also reduces cardiac preload and afterload, improving cardiac output and reducing symptoms of heart failure.
**Why Each Wrong Option is Incorrect**
**Option A:** This option is not provided.
**Option B:** This option is not provided.
**Option C:** This option is not provided.
**Option D:** This option is not provided.
**Clinical Pearl / High-Yield Fact**
Nesiritide is contraindicated in patients with systolic blood pressure less than 90 mmHg due to the risk of further hypotension. It is essential to monitor blood pressure closely when administering nesiritide.
**Correct Answer:** D.
