A nurse is caring for a client who is in premature labor and is receiving terbutaline. The nurse should monitor the client for which of the following adverse effects that should be reported to the provider?

Choice A reason: This statement is correct, as the ultrasound can help diagnose placenta previa, which is a condition where the placenta covers the cervical opening and can cause painless, bright red bleeding in the third trimester. Placenta previa is a serious complication that can affect the delivery and the fetal oxygenation.

Choice B reason: This statement is incorrect, as the biparietal diameter is a measurement of the fetal head that is used to estimate the gestational age and the fetal growth. The biparietal diameter is not related to the cause or the severity of the bleeding.

Choice C reason: This statement is incorrect, as the fetal lung maturity is an assessment of the surfactant level in the amniotic fluid that is used to predict the risk of respiratory distress syndrome in preterm infants. The fetal lung maturity is not related to the cause or the severity of the bleeding.

Choice D reason: This statement is incorrect, as the viability of the fetus is an evaluation of the fetal heart rate, movement, and tone that is used to determine the fetal well-being and distress. The viability of the fetus is not related to the cause or the severity of the bleeding, although it can be affected by it.

Choice A reason: Reinforcing postpartum and newborn care discharge teaching is not a priority action by the nurse, as it is not directly related to the client's emotional state or safety. Reinforcing postpartum and newborn care discharge teaching is an important intervention that can help the client to manage her physical recovery and her infant's needs, but it is not sufficient to address the client's symptoms of postpartum depression, which is a mood disorder that can affect the client's mental health and well-being.

Choice B reason: Asking the client if she has considered harming her newborn is a priority action by the nurse, as it is essential to assess the client's risk of infanticide, which is the intentional killing of an infant by the mother. Asking the client if she has considered harming her newborn is a sensitive and difficult question, but it is necessary to ensure the safety of the infant and the mother, and to provide appropriate interventions and referrals. The nurse should ask the question in a nonjudgmental and supportive manner, and validate the client's feelings and concerns.

Choice C reason: Assisting the family to identify prior use of positive coping skills in family crises is not a priority action by the nurse, as it is not directly related to the client's emotional state or safety. Assisting the family to identify prior use of positive coping skills in family crises is a helpful intervention that can enhance the client's resilience and self-efficacy, but it is not sufficient to address the client's symptoms of postpartum depression, which is a mood disorder that can affect the client's mental health and well-being.

Choice D reason: Anticipating a prescription by the provider for an antidepressant is not a priority action by the nurse, as it is not directly related to the client's emotional state or safety. Anticipating a prescription by the provider for an antidepressant is a possible intervention that can improve the client's mood and functioning, but it is not the only or the first option to address the client's symptoms of postpartum depression, which is a mood disorder that can affect the client's mental health and well-being. The nurse should collaborate with the provider and the client to determine the best treatment plan, which may include psychotherapy, social support, or alternative therapies.
