A woman with severe preeclampsia is being treated with bed rest and intravenous magnesium sulfate. The drug classification of this medication is

Choice a) Headaches is correct because this is a condition that can indicate a serious problem in the postpartum period and may require careful medical assessment. Headaches are common in the first few weeks after giving birth, but they can also be a sign of complications such as preeclampsia, eclampsia, cerebral venous thrombosis, meningitis, or aneurysm. Preeclampsia and eclampsia are conditions that cause high blood pressure, proteinuria, and seizures in pregnant or postpartum women. Cerebral venous thrombosis is a blood clot in the brain that can cause stroke-like symptoms. Meningitis is an infection of the membranes that cover the brain and spinal cord. Aneurysm is a bulge or rupture in a blood vessel that can cause bleeding in the brain. These conditions can be life-threatening and require immediate treatment. Therefore, women who experience severe, persistent, or unusual headaches in the postpartum period should seek medical attention as soon as possible.

Choice b) Varicosities of the legs is incorrect because this is not a condition that usually requires careful medical assessment in the postpartum period. Varicosities are enlarged or swollen veins that appear blue or purple under the skin. They are common in pregnancy due to increased blood volume, hormonal changes, and pressure from the growing uterus. They usually improve after delivery, but may persist or worsen in some women. Varicosities are usually harmless and do not cause any symptoms, but they may cause cosmetic concerns, discomfort, itching, or bleeding. They can also increase the risk of superficial thrombophlebitis, which is inflammation of a vein near the skin surface. However, these complications are rare and mild, and can be managed with conservative measures such as compression stockings, elevation of the legs, exercise, and painkillers. Therefore, women who have varicosities of the legs in the postpartum period do not need to worry too much, unless they have signs of infection or deep vein thrombosis, which is a more serious condition that involves a blood clot in a deep vein that can travel to the lungs and cause pulmonary embolism.

Choice c) Carpal tunnel syndrome is incorrect because this is not a condition that typically requires careful medical assessment in the postpartum period. Carpal tunnel syndrome is a condition that causes numbness, tingling, pain, or weakness in the hand and wrist due to compression of the median nerve that runs through a narrow passage called the carpal tunnel. It can occur in pregnancy due to fluid retention, hormonal changes, or repetitive movements. It usually resolves after delivery, but may persist or recur in some women. Carpal tunnel syndrome is usually mild and does not cause any serious complications, but it may interfere with daily activities or quality of life. It can be treated with conservative measures such as splinting, icing, massage, stretching, or painkillers. In severe cases, surgery may be needed to release the pressure on the nerve. Therefore, women who have carpal tunnel syndrome in the postpartum period do not need to seek medical attention urgently, unless they have signs of nerve damage or infection.

Choice d) Periodic numbness and tingling of the fingers is incorrect because this is not a condition that generally requires careful medical assessment in the postpartum period. Periodic numbness and tingling of the fingers can be caused by various factors such as cold exposure, poor circulation, nerve compression, vitamin deficiency, or anxiety.

It can also occur in pregnancy due to fluid retention or hormonal changes. It usually goes away after delivery, but may linger or come back in some women. Periodic numbness and tingling of the fingers is usually harmless and does not indicate any serious problem, but it may cause discomfort or annoyance. It can be relieved with simple measures such as warming up, moving around, shaking out the hands, taking supplements, or relaxing. Therefore, women who experience periodic numbness and tingling of the fingers in the postpartum period do not need to worry too much, unless they have signs of infection or neurological disorder.

Choice A) Decreased metabolic rate is incorrect because this is not a result of hypothermia in the newborn, but rather a cause of it. Metabolic rate is the speed at which the body uses energy to perform its functions. Newborns have a high metabolic rate, which helps them to maintain a normal body temperature of 36.5°C to 37.5°C (97.7°F to 99.5°F). However, some factors can lower the metabolic rate of newborns, such as prematurity, low birth weight, infection, or hypoglycemia. A low metabolic rate can make the newborn more susceptible to heat loss and hypothermia, which is a condition that occurs when the body temperature drops below 36°C (96.8°F). Therefore, this response is inaccurate and misleading.

Choice B) Decreased oxygen demands is incorrect because this is not a result of hypothermia in the newborn, but rather a consequence of it. Oxygen demand is the amount of oxygen that the body needs to function properly.

Newborns have a high oxygen demand, which helps them to support their growth and development. However, some factors can decrease the oxygen demand of newborns, such as hypothermia, sedation, or asphyxia. A low oxygen demand can impair the oxygen delivery and utilization by the tissues and organs, leading to hypoxia, acidosis, or organ failure. Therefore, this response is irrelevant and inaccurate.

Choice C) Shivering to generate heat is incorrect because this is not a result of hypothermia in the newborn, but rather a mechanism that is absent in them. Shivering is an involuntary contraction of the muscles that produces heat and raises the body temperature. It is a common response to cold exposure in adults and older children, but not in newborns. Newborns do not have the ability to shiver, as their muscles are immature and lack glycogen stores.

Instead, they rely on other methods to generate heat, such as non-shivering thermogenesis, which involves burning brown fat in certain areas of the body. Therefore, this response is irrelevant and inaccurate.

Choice D) Increased glucose demands is correct because this is a result of hypothermia in the newborn that can cause complications. Glucose demand is the amount of glucose that the body needs to produce energy and maintain its functions. Newborns have a high glucose demand, which helps them to support their metabolic rate and thermoregulation. However, some factors can increase the glucose demand of newborns, such as hypothermia, stress, or infection. A high glucose demand can deplete the glucose stores and cause hypoglycemia, which is a low level of glucose in the blood that can lead to seizures, brain damage, or death. Therefore, this response is clear and accurate.
