Match the description with the associated stage of labor.

Choice A rationale

Misoprostol (Cytotec) stimulates smooth muscle contraction, including the gastrointestinal tract, leading to increased bowel motility and diarrhea. Normal bowel frequency ranges from 3 times per day to 3 times per week.

Choice B rationale

Methergine (Methylergonovine) constricts blood vessels, leading to increased blood pressure and a risk of hypertensive crisis. Normal blood pressure is around 120/80 mmHg.

Choice C rationale

Hemabate (carboprost tromethamine) is a prostaglandin analog, which can cause bronchoconstriction, exacerbating asthma symptoms in patients. Normal peak flow ranges from 400-700 L/min.

Choice D rationale

Oxytocin (Pitocin) can cause fever, chills, and hypotension due to its effects on vascular smooth muscle and thermoregulatory centers. Normal body temperature is around 37°C (98.6°F).

Choice A rationale

MRI is not typically used for assessing placental perfusion or IUGR. It provides detailed imaging but is not the primary tool for evaluating fetal growth.

Choice B rationale

Doppler Flow Studies are used to assess placental and fetal blood flow, making them crucial for evaluating placental perfusion and diagnosing IUGR in gestational hypertension.

Choice C rationale

Amniocentesis is used for genetic testing and assessing fetal lung maturity, not for evaluating placental perfusion or diagnosing IUGR in gestational hypertension.

Choice D rationale

Chorionic Villus Sampling (CVS) is for early genetic testing and not suitable for assessing placental perfusion or IUGR, which requires evaluation of blood flow.
