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. This test determines if your baby is at risk for developing hypoglycemia after birth: The indirect Coombs' test is not related to assessing the risk of hypoglycemia in the baby. It specifically focuses on Rh sensitization.

B. The test will determine the amount of amniotic fluid around the fetus: The indirect Coombs' test does not assess the amount of amniotic fluid around the fetus. It is specifically aimed at detecting antibodies in the maternal blood.

C. The test studies blood flow in the fetus and placenta using ultrasound waves: This description is more indicative of a Doppler ultrasound or other tests that assess blood flow. The indirect Coombs' test is a blood test and does not involve ultrasound waves.

D. This test will detect the presence of Rh-positive antibodies in your blood

The indirect Coombs' test is performed during pregnancy to detect the presence of Rh antibodies in the maternal bloodstream. Rh antibodies can develop if an Rh-negative mother is carrying an Rh-positive baby, and there is a risk of hemolytic disease of the newborn (HDN) in subsequent pregnancies. The test helps identify if the mother has developed antibodies against Rh-positive blood, which could potentially affect the fetus.

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.
