A nurse is caring for a client who is having a nonstress test. The fetal heart rate (FHR) baseline is 145 bpm, there is moderate variability, but there have been no accelerations or fetal movement. Which of the following actions should the nurse complete next?

Choice A rationale

Diarrhea is a common adverse effect of Hemabate (carboprost tromethamine). It stimulates smooth muscle contractions, including gastrointestinal tract muscles, leading to increased bowel movements.

Choice B rationale

Methergine (Methylergonovine) can cause a hypertensive crisis due to its potent vasoconstrictive properties. It is contraindicated in patients with hypertension or preeclampsia.

Choice C rationale

Hemabate (carboprost tromethamine) may exacerbate asthma. It can cause bronchoconstriction by stimulating prostaglandin receptors, worsening asthma symptoms or triggering attacks.

Choice D rationale

Misoprostol (Cytotec) can cause fever, chills, and hypotension due to its inflammatory and vasodilatory effects. It increases prostaglandin synthesis, leading to these systemic responses.

Choice A rationale

Administering oxytocin during a contraction stress test is to assess uteroplacental insufficiency, not to identify pain tolerance. The test evaluates fetal response to contractions.

Choice B rationale

Positive contraction stress tests are associated with poor fetal outcomes, indicating fetal distress during contractions due to inadequate placental perfusion.

Choice C rationale

A negative result in a contraction stress test indicates adequate placental function and fetal well-being, suggesting the fetus can tolerate labor without distress.

Choice D rationale

A positive test result suggests potential fetal compromise, including increased risk of fetal death, growth restriction, low Apgar scores, and need for C-section or resuscitation.
