A nurse is caring for a client who has oligohydramnios and is undergoing a biophysical profile (BPP).

The nurse should expect to see which of the following findings on the ultrasound?

This means that the baby’s heart rate did not slow down after the contractions induced by oxytocin, which is a sign of normal fetal well-being.

A negative CST is normal and desirable.

Choice A is wrong because no contractions were induced during the test.

This means that the test was inconclusive and could not assess the baby’s response to stress.

Choice B is wrong because late decelerations of the FHR were observed with at least 50% of contractions.

This means that the baby’s heart rate slowed down and stayed slow after the contractions, which is a sign of fetal distress and hypoxia.

A positive CST is abnormal and concerning.

Choice D is wrong because the client experienced mild uterine cramping during the test.

This is not a relevant factor for interpreting the CST results, which depend on the FHR patterns.

Uterine cramping can be a side effect of oxytocin administration or nipple stimulation.

This is a contraindication for the Contraction Stress Test (CST) because it increases the risk of infection and umbilical cord prolapse.

A CST is a test that measures the baby’s heart rate during uterine contractions induced by oxytocin or nipple stimulation.

Choice A is wrong because gestational diabetes is not a contraindication for the CST.

It is a condition that affects how the body processes glucose during pregnancy and may cause complications such as macrosomia (large baby), hypoglycemia (low blood sugar) or preeclampsia (high blood pressure and protein in urine).

Choice B is wrong because mild preeclampsia is not a contraindication for the CST.

It is a condition that causes high blood pressure and protein in urine after 20 weeks of pregnancy and may affect the placenta, kidneys, liver or brain.

Choice C is wrong because preterm labor is a relative contraindication for the CST, not an absolute one.

It means that the test may be performed if the benefits outweigh the risks, but it should be avoided if possible because it may trigger early labor or delivery.

Preterm labor is defined as regular uterine contractions with cervical changes before 37 weeks of pregnancy.

Normal ranges for blood pressure are below 120/80 mmHg, for glucose are 70-100 mg/dL (fasting) or below 140 mg/dL (2 hours after eating), and for protein in urine are less than 300 mg/24 hours.
