An 18-hour-old baby with an elevated bilirubin level is placed under the bili lights.Which of the following is an expected nursing action in these circumstances?

Choice A rationale

Reduction of fever is not a primary effect of carboprost tromethamine. This medication is primarily used to induce uterine contractions to manage postpartum hemorrhage.

Choice B rationale

While maintaining stable blood pressure is important, it is not the specific indicator of carboprost tromethamine's effectiveness. This medication is used to control bleeding.

Choice C rationale

Increased comfort, although significant, is not the direct effect of carboprost tromethamine. The primary aim is to induce uterine contractions to manage hemorrhage.

Choice D rationale

Decreased lochia rubra indicates the reduction of postpartum bleeding, which is the primary purpose of administering carboprost tromethamine. This outcome shows the medication is effective.

Choice A rationale

History of preterm birth is the principal risk factor for predicting preterm birth. Previous preterm births significantly increase the likelihood of subsequent preterm deliveries due to underlying etiological factors.

Choice B rationale

Low prepregnancy weight is a risk factor but not as significant as a history of preterm birth. It can contribute to complications in pregnancy but does not have the same predictive value.

Choice C rationale

Smoking during pregnancy increases the risk of preterm birth but is not the principal risk factor. It is a modifiable behavior that contributes to poor pregnancy outcomes.

Choice D rationale

Obesity can impact pregnancy outcomes but is not the principal risk factor for preterm birth. It is associated with other complications rather than directly predicting preterm delivery.
