A nurse is caring for a client who is receiving terbutaline to treat preterm labor. Which of the following findings should the nurse identify as a potential adverse effect of this medication?

A. Three fetal movements perceived by the client in a 20-min testing period: Perceiving fetal movements during the testing period is a positive finding and indicative of fetal well-being.

B. An increase in fetal heart rate to 150/min above the baseline of 140/min lasting 10 seconds in response to fetal movement within a 40-min testing period: This is considered a reassuring result in an NST, showing an appropriate acceleration in the fetal heart rate in response to fetal movement, which is a normal and positive finding.

C. Irregular contractions of 10 to 20 seconds in duration that are not felt by the client

During a nonstress test (NST), the presence of uterine contractions can sometimes interfere with the interpretation of fetal heart rate (FHR) patterns. If contractions occur but are not felt by the client, it can affect the accuracy of the test. Therefore, irregular contractions that are not felt by the client may prompt the need for further evaluation or testing to ensure accurate assessment of fetal well-being.

D. No late decelerations in the fetal heart rate noted with three uterine contractions of 60 seconds in duration within a 10-min testing period: Absence of late decelerations during uterine contractions is also a reassuring finding, indicating that the baby is tolerating the stress of contractions well.

A. Administer 500 ml lactated Ringer's IV bolus:

This choice may be relevant in the context of postpartum hemorrhage, but the first step should be to assess the client's status, including urinary output. Administering fluids without a clear assessment may not address the underlying cause.

B. Replace the surgical dressing:

Vaginal bleeding after a cesarean birth is unlikely to be addressed by replacing the surgical dressing. This action may not address the root cause of the bleeding, which needs further assessment.

C. Apply an ice pack to the incision site:

Using an ice pack is not the appropriate intervention for postpartum bleeding. Ice is typically used for pain and swelling, not for controlling bleeding.

D. Evaluate urinary output:

This is the correct choice. Evaluating urinary output is crucial to assess the client's overall fluid status and kidney perfusion. In the context of postpartum bleeding, it helps determine if there is hypovolemia or other issues contributing to the bleeding. Adequate urinary output is a positive sign of organ perfusion.
