A nurse is providing care for a client who is in preterm labor at 32 weeks of gestation.

Which medication should the nurse expect the provider to prescribe to accelerate fetal lung maturity?

Choice A rationale
Uterine atony refers to a soft and weak uterus after childbirth. It happens when your uterine muscles don’t contract enough to clamp the placental blood vessels shut after childbirth. This can lead to life-threatening blood loss after delivery. One of the causes of uterine atony is urinary retention. When the bladder is full, it can displace the uterus, preventing it from contracting properly. This can lead to uterine atony and postpartum hemorrhage. Therefore, urinary retention can cause uterine atony and lateral displacement of the fundus.
Choice B rationale
Poor involution of the uterus is a condition where the uterus does not return to its normal size after childbirth. While poor involution can lead to prolonged bleeding, it does not directly cause uterine atony. Uterine atony is specifically a lack of muscle contraction, while poor involution is a failure of the uterus to reduce in size.
Choice C rationale
While infection can lead to many complications during the postpartum period, it is not a direct cause of uterine atony. Infections can cause endometritis, which is inflammation of the uterine lining, but this does not prevent the uterus from contracting.
Choice D rationale
Hemorrhage, or heavy bleeding, is a result of uterine atony, not a cause. When the uterus does not contract properly after childbirth, it can lead to excessive bleeding, or hemorrhage.

Choice A rationale
Supporting the casted arm with a firm grasp is important to prevent unnecessary movement and potential discomfort or injury to the child. It also helps in ensuring the correct positioning of the cast.
Choice B rationale
Placing a heated fan at the bedside to facilitate drying is not recommended. Excessive heat can cause discomfort and potential burns to the child. The cast should be allowed to dry naturally.
Choice C rationale
Telling the child that the cast will make their arm feel better can be misleading. While the cast is necessary for healing, it may cause discomfort and itching. It’s important to explain to the child what the cast is for and what to expect.
Choice D rationale
Wrapping the arm of the child’s doll or toy prior to the procedure can help the child understand what is happening and make them feel more comfortable. However, this action alone is not sufficient in preparing to apply a cast to a preschooler’s arm.
