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 correct answer is choice B. Monitor fetal heart rate.

This is because cramping and vaginal bleeding after amniocentesis are signs of possible complications such as miscarriage, preterm labor, or injury to the fetus.

Monitoring fetal heart rate can help assess the well-being of the fetus and detect any signs of distress.

Choice A is wrong because administering Rho(D) immunoglobulin is only necessary if the mother has Rh-negative blood and the baby has Rh-positive blood, which can cause Rh sensitization.

This is not given routinely to all women who have amniocentesis.

Choice C is wrong because assessing maternal vital signs is not the first priority when there is a risk of fetal compromise.

Maternal vital signs can be affected by many factors and are not specific indicators of fetal health.

Choice D is wrong because obtaining an order for an ultrasound exam is not the first action to take.

An ultrasound exam can help confirm the diagnosis of complications such as placental abruption or fetal demise, but it requires time and equipment that might delay immediate intervention.

Monitoring fetal heart rate can be done quickly and easily at the bedside.

A contraction stress test (CST) is a test that simulates labor contractions to see how the baby’s heart rate responds to the stress of uterine contractions.

The biggest risk of the test is that it may cause the pregnant person to go into labor before their due date.

Some possible explanations for the other choices are:

Choice B. Premature rupture of membranes.

This is a condition where the amniotic sac breaks before labor begins.

It can increase the risk of infection and cord prolapse, but it is not a direct complication of CST.

Choice C. Infection.

This is a possible risk of any invasive procedure, but CST is usually done with external fetal monitoring and oxytocin infusion, which do not require breaking the skin or entering the uterus.

Choice D. Bleeding.

This is a potential risk of CST for people who have placenta previa, a condition where the placenta covers the cervix and can detach during contractions.

However, CST is not recommended for people who have placenta previa or other conditions that increase the risk of uterine rupture or bleeding.
