The nurse is caring for a client in labor at term. The nurse reviews the external monitor tracing below. The nurse identifies that the deceleration pattern seen indicates which of the following?

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.
