A nurse is reviewing the contraindications for a Contraction Stress Test (CST) with a pregnant client.

Which condition would be a contraindication for the test?

Gestational diabetes.

Mild preeclampsia.

Preterm labor.

Ruptured membranes.

Answer and Explanation

The Correct Answer is D

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.

Correct Answer is A

Explanation

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.

A. Administer Rho(D) immune globulin. B. Monitor fetal heart rate C. Assess maternal vital signs D. Obtain an order for an ultrasound exam

Correct Answer is B

Explanation

This is because cramping and vaginal bleeding after an amniocentesis may indicate a possible miscarriage or placental abruption, which can compromise fetal oxygenation and perfusion.

Monitoring fetal heart rate can help detect signs of fetal distress and guide further interventions.

Choice A is wrong because administering Rho(D) immune globulin is indicated for Rh-negative mothers who undergo amniocentesis to prevent isoimmunization, but it is not a priority action in this scenario.

Choice C is wrong because assessing maternal vital signs is important to monitor for signs of infection, hemorrhage, or shock, but it is not as urgent as monitoring fetal well-being.

Choice D is wrong because obtaining an order for an ultrasound exam can help confirm the diagnosis and evaluate the placenta and amniotic fluid, but it is not the first action to take in this situation.
