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

What does an equivocal CST indicate?

Late decelerations of the FHR with less than 50% of contractions.

Late decelerations of the FHR with at least 50% of contractions.

No late decelerations of the FHR during contractions.

Variable decelerations of the FHR with or without contractions.

Answer and Explanation

The Correct Answer is A

An equivocal CST indicates late decelerations of the FHR with less than 50% of contractions.

This means that the fetus may have some degree of hypoxia or distress, but not enough to warrant immediate delivery.

An equivocal CST may also result from hyperstimulation of the uterus, which can cause excessive contractions and reduce blood flow to the placenta.

Choice B is wrong because late decelerations of the FHR with at least 50% of contractions is a positive CST, which indicates a high risk of fetal death due to hypoxia and is a contraindication to labor.

Choice C is wrong because no late decelerations of the FHR during contractions is a negative CST, which indicates a good fetal wellbeing and tolerance of labor.

Choice D is wrong because variable decelerations of the FHR with or without contractions are not related to uterine activity and may indicate cord compression or other fetal problems.

Variable decelerations are not used to interpret CST results.

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. To measure the fetal heart rate (FHR) in response to fetal movements. B. To monitor the uterine contractions. C. To indicate adequate fetal oxygenation and normal fetal neurological function. D. To assess fetal well-being and identify fetal hypoxia or distress.

Correct Answer is A

Explanation

To measure the fetal heart rate (FHR) in response to fetal movements.

This is because the FHR should increase by at least 15 beats per minute for at least 15 seconds when the fetus moves, which indicates a healthy and reactive fetus.

This is called an acceleration.

Choice B is wrong because the uterine contractions are not related to the fetal movements or the button pressing.

The uterine contractions are measured by a tocodynamometer or an intrauterine pressure catheter.

Choice C is wrong because the fetal oxygenation and neurological function are not directly measured by the button pressing.

The fetal oxygenation can be assessed by the FHR variability and decelerations, while the neurological function can be evaluated by other tests such as biophysical profile or fetal acoustic stimulation.

Choice D is wrong because the fetal well-being and hypoxia or distress are not indicated by the button pressing alone.

The fetal well-being and hypoxia or distress are determined by the FHR patterns, such as baseline, variability, accelerations and decelerations.
