What is the only known cure for preeclampsia?

Choice a) Consult the physician, because the dose is too high is incorrect because this is not a necessary or appropriate action for a nurse who is following a valid order for betamethasone. Betamethasone is a corticosteroid that can be used to accelerate fetal lung maturation and reduce the risk of respiratory distress syndrome and other complications in preterm infants. The recommended dose for betamethasone is 12 mg IM every 24 hours for two doses, which is exactly what the physician ordered. Therefore, there is no reason to question or consult the physician about the dose, as it is within the normal range and based on evidence-based practice.

Choice b) Schedule the second dose for 11 am on the next day is incorrect because this is not a correct or accurate way to implement the order for betamethasone. Betamethasone should be given at least 24 hours apart, but not more than 48 hours apart, to achieve optimal fetal lung development and neonatal outcomes. Scheduling the second dose for 11 am on the next day would result in a 24-hour interval between the doses, which is acceptable, but not ideal. The best time to schedule the second dose would be between 24 and 48 hours after the first dose, such as at 11 pm on the same day or at 7 am on the next day.

Choice c) Prepare to administer the medication intramuscularly between contractions is correct because this is the best and most appropriate way to implement the order for betamethasone. Betamethasone should be given by intramuscular injection in a large muscle mass, such as the deltoid or gluteus, using a 21-gauge needle and a syringe with an air lock. The injection site should be cleaned with alcohol and aspirated before injecting. The medication should be administered between contractions, when the uterine blood flow is maximal and the fetal absorption is optimal. The nurse should also monitor the woman and the fetus for any adverse effects of betamethasone, such as maternal hyperglycemia, hypertension, infection, or edema, or fetal tachycardia, hypoglycemia, or infection.

Choice d) Explain to the woman that this medication will reduce her heart rate and help her to breathe easier is incorrect because this is not a true or relevant statement about betamethasone. Betamethasone does not have any direct effect on the maternal heart rate or respiratory function, as it is mainly intended to improve the fetal lung maturation and reduce the risk of respiratory distress syndrome and other complications in preterm infants.

Betamethasone may cause some side effects such as increased blood pressure, blood sugar, or fluid retention in the mother, which may affect her cardiovascular or respiratory status indirectly. However, these effects are usually transient and mild, and do not outweigh the benefits of betamethasone for the fetus. Therefore, this statement is misleading and inaccurate.

Choice A) Weight gain of 0.5 kg during the past 2 weeks: This is a normal weight gain for a pregnant woman and does not indicate preeclampsia.

Choice B) Pitting pedal edema at the end of the day: This is a common symptom of pregnancy and does not necessarily indicate preeclampsia. It can be relieved by elevating the legs and wearing compression stockings.

Choice C) Blood pressure increase to 138/86 mm Hg: This is a mild elevation of blood pressure and does not meet the criteria for preeclampsia, which is defined as a systolic blood pressure of 140 mm Hg or higher or a diastolic blood pressure of 90 mm Hg or higher on two occasions at least four hours apart.

Choice D) Dipstick value of 3+ for protein in her urine: This is a sign of significant proteinuria, which is one of the main features of preeclampsia. Proteinuria is defined as a urinary protein excretion of 300 mg or more in 24 hours or a dipstick reading of 1+ or higher. A dipstick value of 3+ indicates severe proteinuria and requires immediate attention and treatment. This woman has the highest risk of developing complications from preeclampsia, such as eclampsia, HELLP syndrome, placental abruption, or fetal growth restriction . Therefore, she should be seen by the nurse first.
