The student nurse asks why gloves are needed when handling a newborn because the newborn "hasn't been exposed to anything". What response by the nurse is best?

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) I will be certain to empty the litter boxes regularly is incorrect because this is a risky behavior for a pregnant woman who wants to prevent toxoplasmosis. Toxoplasmosis is an infection caused by a parasite called Toxoplasma gondii, which can be found in the feces of cats and other animals. If a pregnant woman gets infected with toxoplasmosis, she can pass it to her unborn baby, which can cause serious problems such as miscarriage, stillbirth, or birth defects. Therefore, a pregnant woman should avoid contact with cat litter and let someone else handle the litter boxes, or wear gloves and wash her hands thoroughly if she has to do it herself.

Choice b) I have to wash all of my fruits and vegetables is correct because this is a good practice for a pregnant woman who wants to prevent toxoplasmosis. Toxoplasmosis can also be transmitted through contaminated soil or water, which can adhere to fruits and vegetables. Therefore, a pregnant woman should wash all of her fruits and vegetables before eating them, and peel or cook them if possible, to remove any traces of the parasite.

Choice c) I won't eat raw eggs is correct because this is another good practice for a pregnant woman who wants to prevent toxoplasmosis. Toxoplasmosis can also be acquired through eating undercooked or raw meat or eggs that contain the parasite. Therefore, a pregnant woman should avoid eating raw eggs or any foods that contain them, such as mayonnaise, mousse, or homemade ice cream, and cook all of her meat and eggs thoroughly until they are no longer pink or runny.

Choice d) I need to be cautious when cooking meat is correct because this is also an important practice for a pregnant woman who wants to prevent toxoplasmosis. Toxoplasmosis can also be spread through handling raw meat that contains the parasite. Therefore, a pregnant woman should be careful when cooking meat and use separate utensils and cutting boards for raw and cooked meat, wash her hands and surfaces after touching raw meat, and avoid tasting raw meat while cooking it.
