Which data should alert the nurse that the neonate is postmature?

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) 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.
