A nurse is caring for a client who is at 14 weeks of gestation and has hyperemesis gravidarum. Which of the following medications should the nurse plan to administer?

Assess the fetal heart rate pattern.

Choice B rationale:

When a laboring client's membranes have just ruptured, the nurse's next action should be to assess the fetal heart rate pattern. Rupture of membranes can lead to changes in amniotic fluid, which can affect the fetal environment and potentially cause fetal distress. By assessing the fetal heart rate pattern, the nurse can determine if the baby is tolerating the labor process well or if there are signs of fetal compromise that require further intervention.

Choice A rationale:

While assessing the client's blood pressure (Choice A) is important during labor, it is not the immediate next action when the membranes have ruptured.

Choice C rationale:

Taking the client's temperature (Choice C) is also important, but it is not the priority action when the membranes have ruptured.

Choice D rationale:

Preparing for a c-section (Choice D) is not the initial action unless there are specific indications for an emergency cesarean section. Assessing the fetal heart rate is more critical at this stage.

Choice A rationale:

Keeping the newborn dressed while receiving phototherapy is not recommended because the baby's skin needs to be exposed to the light to effectively treat hyperbilirubinemia. Direct exposure to light helps break down the excess bilirubin in the baby's blood, leading to its excretion.

Choice B rationale:

Applying lotion to the skin twice daily is contraindicated during phototherapy. Lotions and creams can block the light from reaching the skin and hinder the therapeutic effects of the phototherapy. The baby's skin should remain exposed to the light for optimal treatment.

Choice C rationale:

Maintaining an eye mask over the newborn's eyes is essential during phototherapy. The eyes are sensitive to light, and prolonged exposure to the phototherapy light can lead to eye damage. Using an eye mask protects the baby's eyes while allowing the rest of the body to receive the necessary light treatment.

Choice D rationale:

Maintaining the phototherapy during blood draws is crucial to ensure continuous treatment of hyperbilirubinemia. Interrupting the phototherapy during blood draws might result in the rebound of bilirubin levels, which can be harmful to the baby.
