During a Non-Stress Test (NST), the client needs to press a button whenever they feel the fetus move.

What is the purpose of this action?

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

To monitor the uterine contractions.

To indicate adequate fetal oxygenation and normal fetal neurological function.

To assess fetal well-being and identify fetal hypoxia or distress.

Answer and Explanation

The Correct Answer is A

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.

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.

A. Late decelerations of the FHR with less than 50% of contractions. B. Late decelerations of the FHR with at least 50% of contractions. C. No late decelerations of the FHR during contractions. D. Variable decelerations of the FHR with or without contractions.

Correct Answer is A

Explanation

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.
