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

This is because migraine headaches with aura are a contraindication for receiving oral contraceptives, as they increase the risk of stroke and other cardiovascular complications.

Some possible explanations for the other choices are:

Choice B: A 32-year-old client who has endometriosis.

This is not a contraindication for receiving oral contraceptives, as they can actually help reduce the symptoms of endometriosis by suppressing ovulation and reducing menstrual bleeding.

Choice C: A 28-year-old client who has polycystic ovary syndrome (PCOS).

This is not a contraindication for receiving oral contraceptives, as they can help regulate the menstrual cycle and lower the levels of androgens (male hormones) that cause acne, hirsutism (excess hair growth), and other problems in women with PCOS.

Choice D: A 22-year-old client who has irregular menstrual cycles.

This is not a contraindication for receiving oral contraceptives, as they can help normalize the menstrual cycle and prevent unintended pregnancy.

Normal ranges for oral contraceptive doses are:

Estrogen: 10 to 35 mcg of ethinyl estradiol or estradiol valerate

Progestin: varies depending on the type and brand of oral contraceptive

A. “This test can detect neural tube defects.”. B. “This test can detect genetic disorders.”. C. “This test can detect chromosomal abnormalities.”. D. “This test can detect Rh sensitization.”.

Correct Answer is B

Explanation

This test can detect genetic disorders.

Chorionic villus sampling (CVS) is a prenatal test that involves taking a sample of tissue from the placenta to test for chromosomal abnormalities and certain other genetic problems.

The placenta is a structure in the uterus that provides blood and nutrients from the mother to the fetus.

Choice A is wrong because CVS does not provide information on neural tube defects, such as spina bifida.

For this reason, women who undergo CVS also need a follow-up blood test between 16 to 18 weeks of their pregnancy to screen for neural tube defects.

Choice C is wrong because CVS can detect chromosomal abnormalities, but not all chromosomal abnormalities are genetic disorders.

For example, Down syndrome is a chromosomal abnormality caused by an extra copy of chromosome 21, but it is not inherited from the parents.

Choice D is wrong because CVS cannot detect Rh sensitization, which is a condition where the mother’s immune system produces antibodies against the fetus’s blood type.

Rh sensitization can be detected by a blood test that measures the level of antibodies in the mother’s blood.
