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 C

Explanation

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.

A. The client’s bladder is full. B. The client’s uterus is above the symphysis pubis C. The client’s cervix is dilated D. The client’s fundal height measures 20 cm

Correct Answer is C

Explanation

. The client’s cervix is dilated.

This indicates that the client may be in preterm labor, which is a contraindication for amniocentesis.

Amniocentesis is a procedure that involves inserting a needle into the amniotic sac to obtain a sample of amniotic fluid for genetic testing or other purposes.

It is usually performed between 15 and 20 weeks of gestation.

Choice A is wrong because the client’s bladder should be full for amniocentesis.

This helps to push the uterus upward and away from the bladder, reducing the risk of injury and making it easier to visualize the fetus and the needle.

Choice B is wrong because the client’s uterus should be above the symphysis pubis at 16 weeks of gestation.

This is a normal finding and does not affect the procedure.

Choice D is wrong because the client’s fundal height should measure around 16 cm at 16 weeks of gestation.

A fundal height of 20 cm may indicate a large for gestational age fetus, multiple gestation, or polyhydramnios (excess amniotic fluid), but these are not absolute contraindications for amniocentesis.

However, they may require further evaluation and adjustment of the technique.
