All of the following can be administrated in acute hypeension during labour EXCEPT:
**Core Concept**
Labetalol, hydralazine, and nifedipine are commonly used antihypertensive agents in the management of acute hypertension during labor. These medications are chosen for their ability to safely reduce blood pressure without causing significant maternal or fetal compromise.
**Why the Correct Answer is Right**
Labetalol is a mixed alpha and beta-blocker that is commonly used to treat hypertension during pregnancy and labor. Hydralazine is a direct vasodilator that acts on the arteriolar smooth muscle to decrease peripheral resistance. Nifedipine is a calcium channel blocker that relaxes vascular smooth muscle and reduces blood pressure. **Lidocaine** is a local anesthetic and antiarrhythmic agent that is not typically used to treat acute hypertension during labor.
**Why Each Wrong Option is Incorrect**
* **Option A:** Labetalol is a commonly used antihypertensive agent in labor, making this option incorrect.
* **Option B:** Hydralazine is a direct vasodilator that is often used to treat acute hypertension during labor, so this option is incorrect as well.
* **Option C:** Nifedipine is a calcium channel blocker that is also used to treat acute hypertension during labor, eliminating this option as incorrect.
**Clinical Pearl / High-Yield Fact**
In the management of acute hypertension during labor, it's essential to choose an antihypertensive agent that has a rapid onset of action and minimal risk of fetal compromise. The American College of Obstetricians and Gynecologists (ACOG) recommends labetalol, hydralazine, and nifedipine as first-line agents for this indication.
**Correct Answer: D. Lidocaine**
