A laboring client received meperidine IV one hour prior to delivery. Which of the following medications should the nurse have available to counteract the effects of this medication on the newborn?

Choice A rationale:

High calcium levels are not typically associated with the use of anastrozole, an aromatase inhibitor. Aromatase inhibitors work by blocking the conversion of androgens to estrogens, and they do not directly impact calcium levels.

Choice B rationale:

Muscle and joint pain is a common side effect of aromatase inhibitors like anastrozole. These medications can lead to musculoskeletal discomfort, including joint stiffness and pain, which the nurse should inform the client about to ensure she is aware of potential adverse effects.

Choice C rationale:

Heart failure is not a known side effect of anastrozole. The drug's primary concern is its impact on the musculoskeletal system, particularly causing joint and muscle pain.

Choice D rationale:

Polyphagia, which refers to excessive hunger and increased food intake, is not associated with the use of anastrozole. This choice is unrelated to the side effects of the medication and can be ruled out.

The correct answer is A. Initiate continuous monitoring of the FHR. For a client with placenta previa, continuous fetal heart rate (FHR) monitoring is essential to assess the baby's well-being due to the risk of fetal distress from reduced oxygen supply

Choice A reason:

Continuous FHR monitoring is a standard care practice for clients with placenta previa to promptly detect any signs of fetal distress and intervene as necessary.

Choice B reason:

Betamethasone is typically administered to enhance fetal lung maturity before 34 weeks of gestation, not for placenta previa. Its use at 35 weeks is less common unless there's a risk of preterm birth within 7 days and the patient hasn't received a previous course.

Choice C reason:

Checking the cervix can induce bleeding and is contraindicated in placenta previa because it may disturb the placental site and exacerbate bleeding.

Choice D reason:

Misoprostol is used for labor induction or to treat postpartum hemorrhage. It is not indicated for placenta previa management and can cause uterine contractions leading to increased bleeding.
