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?

“The patient should have a full bladder for a transabdominal US and an empty bladder for a transvaginal US.”1 This is because a full bladder helps to lift the uterus and improve the visibility of the pelvic organs in a transabdominal US, while an empty bladder prevents distortion of the image in a transvaginal US.

Choice B is wrong because tight-fitting clothing is not necessary and lying prone on an examination table is uncomfortable and may interfere with the insertion of the vaginal probe.

Choice C is wrong because loose-fitting clothing is not necessary and lying supine on an examination table may cause supine hypotension syndrome in pregnant women.

Choice D is wrong because loose-fitting clothing is not necessary and lying prone on an examination table is uncomfortable and may interfere with the insertion of the vaginal probe.

“I will have sensors placed on my abdomen to monitor the FHR and uterine contractions.” This statement indicates the client understands the test procedure of a CST, which is a test that triggers contractions and registers how the baby’s heart reacts.

The test is done by placing two sensor belts around the abdomen, one to measure the baby’s heartbeat and the other to measure contractions.

The client may receive oxytocin through an IV to induce contractions.

Choice B is wrong because the client does not need to fast for 24 hours before the test.

There is no evidence that fasting is required for a CST.

Choice C is wrong because the client will not be sedated during the test.

Sedation is not necessary for a CST and may interfere with the results.

Choice D is wrong because the client does not need to drink plenty of fluids before the test.

There is no evidence that drinking fluids is required for a CST.
