The student nurse is assessing a woman with abruptio placentae. The student reports to the registered nurse, "I can't really palpate her abdomen, it's as hard as a board." What action by the nurse is the priority?

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) We are protecting the infant from our bacteria is incorrect because this is not the main reason why gloves are needed when handling a newborn. While it is true that newborns have immature immune systems and are susceptible to infections, gloves are not only used to protect the infant from our bacteria but also to protect ourselves from the infant's body fluids and secretions, which may contain pathogens or blood-borne diseases.

Therefore, this response is incomplete and misleading.

Choice b) Amniotic fluid and maternal blood pose risks to us is incorrect because this is also not the primary reason why gloves are needed when handling a newborn. While it is true that amniotic fluid and maternal blood may contain harmful microorganisms or viruses that can infect us, gloves are not only used to protect ourselves from these substances but also to protect the infant from our skin flora and potential contaminants, which may cause skin irritation or infection. Therefore, this response is also incomplete and misleading.

Choice c) It is hospital policy is incorrect because this is not a sufficient or satisfactory reason why gloves are needed when handling a newborn. While it is true that wearing gloves may be a hospital policy or protocol, this response does not explain the rationale or evidence behind this policy and may imply that the nurse does not understand or agree with it. Therefore, this response is vague and unprofessional.

Choice d) It is part of standard precautions is correct because this is the best and most accurate reason why gloves are needed when handling a newborn. Standard precautions are a set of guidelines and practices that aim to prevent the transmission of infections in healthcare settings. They include wearing gloves, gowns, masks, and eye protection when there is a risk of exposure to blood or body fluids, as well as washing hands before and after patient contact, cleaning and disinfecting equipment and surfaces, and disposing of waste properly. Standard precautions apply to all patients, regardless of their diagnosis or infection status, and are based on the principle that all blood and body fluids are potentially infectious. Therefore, this response is clear and appropriate.
