What is the only known cure for preeclampsia?
Administration of acetylsalicylic acid (ASA) every day of the pregnancy
Delivery of the fetus
Antihypertensive medications
Magnesium sulfate
The Correct Answer is B
Choice A: This is incorrect because acetylsalicylic acid (ASA), also known as aspirin, is not a cure for preeclampsia, but a preventive measure. ASA may reduce the risk of preeclampsia in some high-risk women by inhibiting platelet aggregation and improving blood flow to the placenta. However, ASA is not recommended for all pregnant women, as it may have adverse effects on the mother and the fetus, such as bleeding, premature closure of the ductus arteriosus, or fetal growth restriction.
Choice B: This is the correct answer because delivery of the fetus is the only definitive treatment for preeclampsia, as it eliminates the source of the placental factors that cause the condition. Preeclampsia is a multisystem disorder characterized by hypertension, proteinuria, and edema that occurs after 20 weeks of gestation. It is caused by abnormal placentation and endothelial dysfunction that lead to vasoconstriction, inflammation, and coagulation.
Delivery of the fetus and the placenta resolves these abnormalities and restores normal maternal physiology.
Choice C: This is incorrect because antihypertensive medications are not a cure for preeclampsia, but a symptomatic management. Antihypertensive medications may lower the blood pressure and reduce the risk of maternal complications, such as stroke, seizure, or organ damage. However, antihypertensive medications do not address the underlying cause of preeclampsia and do not improve fetal outcomes. Moreover, some antihypertensive medications are contraindicated in pregnancy due to their teratogenic effects.
Choice D: This is incorrect because magnesium sulfate is not a cure for preeclampsia, but a prophylaxis for eclampsia. Eclampsia is a severe complication of preeclampsia that involves seizures and coma. Magnesium sulfate is an anticonvulsant that prevents or treats eclamptic seizures by stabilizing neuronal membranes and reducing cerebral edema. However, magnesium sulfate does not lower blood pressure or improve renal function in preeclamptic women. It also has side effects such as nausea, flushing, headache, or respiratory depression.

Correct Answer is D
Explanation
Choice a) Urine output of 200 mL for the past 8 hours is incorrect because this is a normal finding for a postpartum woman. The average urine output for a healthy adult is about 800 to 2000 mL per day, which means about 100 to 250 mL per hour. Therefore, a urine output of 200 mL for the past 8 hours is within the normal range and does not indicate any complications.
Choice b) Weight decrease of 2 pounds since delivery is incorrect because this is also a normal finding for a postpartum woman. The weight loss is due to the expulsion of the placenta, amniotic fluid, and blood during delivery. A postpartum woman can expect to lose about 10 to 12 pounds immediately after giving birth, and another 5 pounds in the following weeks due to fluid loss. Therefore, a weight decrease of 2 pounds since delivery is not a cause for concern and does not need to be reported to the obstetrician.
Choice c) Pulse rate of 65 beats per minute is incorrect because this is also a normal finding for a postpartum woman. The normal resting pulse rate for an adult ranges from 60 to 100 beats per minute, and it may decrease slightly after delivery due to blood loss and reduced cardiac output. Therefore, a pulse rate of 65 beats per minute is not indicative of any problems and does not require any intervention.
Choice d) Drop in hematocrit of 6% since admission is correct because this is an abnormal finding for a postpartum woman and suggests that she has developed anemia due to excessive blood loss. Hematocrit is the percentage of red blood cells in the blood, and it reflects the oxygen-carrying capacity of the blood. The normal hematocrit range for an adult female is 37% to 47%, and it may decrease slightly after delivery due to hemodilution. However, a drop in hematocrit of more than 10% from the baseline or below 30% indicates severe anemia and requires immediate treatment. Therefore, a drop in hematocrit of 6% since admission is a significant change that should be reported to the obstetrician as soon as possible.
Correct Answer is ["B","C","D"]
Explanation
Choice A) Calm, easy to comfort is incorrect because this is not a sign of intrauterine drug exposure, but rather a sign of normal or healthy newborn behavior. Newborns who are calm and easy to comfort are usually well-adjusted and have a good temperament. They respond positively to soothing techniques such as holding, rocking, or singing.
They do not show signs of distress or withdrawal, which are common in newborns who are exposed to drugs in utero. Therefore, this response is irrelevant and inaccurate.
Choice B) Tremors is correct because this is a sign of intrauterine drug exposure that can indicate neurological damage or withdrawal syndrome. Tremors are involuntary shaking or quivering movements of the body or limbs that occur due to abnormal electrical activity in the brain or nervous system. Newborns who are exposed to drugs such as opioids, cocaine, or alcohol in utero may develop tremors as a result of brain injury, hypoxia, hypoglycemia, or seizures. They may also experience tremors as a symptom of neonatal abstinence syndrome (NAS), which is a condition that occurs when the newborn stops receiving the drug from the mother and goes through withdrawal. NAS can cause various physical and behavioral problems in the newborn, such as irritability, poor feeding, vomiting, diarrhea, sweating, fever, or seizures. Therefore, this response is clear and accurate.
Choice C) Persistent shrill cry is correct because this is a sign of intrauterine drug exposure that can indicate pain or discomfort in the newborn. Crying is a normal and natural way for newborns to communicate their needs and feelings. However, some newborns who are exposed to drugs such as opioids, cocaine, or alcohol in utero may cry more often, louder, or longer than usual. They may have a high-pitched or piercing cry that is difficult to soothe or stop. This may be due to various factors such as hunger, colic, infection, injury, or withdrawal. A persistent shrill cry can also affect the bonding and attachment between the newborn and the parents or caregivers. Therefore, this response is clear and accurate.
Choice D) Difficult to console is correct because this is a sign of intrauterine drug exposure that can indicate emotional or behavioral problems in the newborn. Newborns who are difficult to console are usually unhappy and restless. They do not respond well to soothing techniques such as holding, rocking, or singing. They may have trouble sleeping, feeding, or interacting with others. They may also show signs of agitation, anxiety, or depression. These problems may be caused by exposure to drugs such as opioids, cocaine, or alcohol in utero, which can affect the development and function of the brain and nervous system. They may also be influenced by the environment and relationship of the newborn with the parents or caregivers. Therefore, this response is clear and accurate.
