A nurse is caring for a newborn who has herpes simplex virus as a result of in utero transmission.
Which of the following actions should the nurse take?

Choice A rationale: Calcium gluconate is the antidote for magnesium sulfate toxicity, often used in labor inductions complicated by preeclampsia or gestational hypertension. Having it readily available ensures prompt treatment of symptoms like respiratory depression or cardiac arrhythmias caused by magnesium overdose. This safety measure is critical because oxytocin use can increase uterine contractions and magnesium sulfate use requires close monitoring to prevent toxicity.

Choice B rationale: Obtaining the client’s heart rate prior to initiating oxytocin is essential to establish a baseline and monitor for tachycardia or bradycardia, which may affect maternal and fetal safety. Oxytocin can cause cardiovascular changes, including hypertension or arrhythmias, especially in clients with gestational hypertension. Continuous maternal cardiac assessment helps detect adverse effects early and adjust treatment accordingly.

Choice C rationale: Evaluating platelet count before induction is important in clients with gestational hypertension due to the risk of HELLP syndrome, which involves thrombocytopenia. Normal platelet levels range from 150,000 to 400,000/mm³; low levels increase bleeding risk during labor and delivery. Knowing platelet status guides safe management decisions, including anesthesia options and readiness for potential hemorrhagic complications.

Choice D rationale: Assessing for aspirin sensitivity is crucial because aspirin is often used in pregnancy for preeclampsia prevention. Aspirin hypersensitivity can lead to allergic reactions or exacerbation of asthma. Since the client has gestational hypertension, determining aspirin tolerance before administering medications is necessary to prevent adverse drug reactions and ensure safe pharmacologic management.

Choice E rationale: Reviewing the client’s history for heart disease documentation is vital as gestational hypertension increases cardiovascular risk. Preexisting heart conditions can complicate labor induction and oxytocin administration due to possible cardiac overload or arrhythmias. A comprehensive cardiac history ensures appropriate monitoring and interventions to prevent maternal and fetal complications during labor.

Choice A rationale

Herpes simplex virus 2 (HSV-2) can be harmful to a developing fetus and newborn. While primary infection during the first trimester can rarely lead to congenital anomalies, the most significant risk is neonatal herpes, which occurs when the newborn is exposed to the virus during passage through the birth canal if active lesions are present. Neonatal herpes can cause severe, life-threatening complications.

Choice B rationale

Transmission of HSV-2 to the newborn is significantly higher if active genital lesions are present at the time of vaginal birth. The virus can be shed from these lesions and infect the infant as they pass through the birth canal. Therefore, a Cesarean section is typically recommended if active lesions are present at the onset of labor.

Choice C rationale

Wearing tight-fitting undergarments can increase moisture and friction, potentially irritating existing lesions and hindering healing. Loose-fitting cotton undergarments are generally recommended to allow air circulation and reduce irritation, promoting a more favorable environment for lesion resolution and comfort.

Choice D rationale

Antiviral medications, such as acyclovir, valacyclovir, or famciclovir, can help manage genital herpes by reducing the frequency, duration, and severity of outbreaks. They work by inhibiting viral replication. However, these medications do not cure the condition; HSV-2 remains a lifelong viral infection.
