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 B

Explanation

A low level of AFP (<0.5 MoM) in a pregnant woman can indicate that the fetus has a chromosomal abnormality, such as Down syndrome or Edwards syndrome.

This is because these conditions affect the development of the fetal liver, which produces AFP.

Choice A is wrong because neural tube defects, such as spina bifida, are associated with high levels of AFP (>2.5 MoM) in the maternal blood.

This is because AFP can leak from the open spinal canal of the fetus into the amniotic fluid and then into the maternal blood.

Choice C is wrong because maternal weight-related factors do not affect the level of AFP in the maternal blood.

However, they can affect the interpretation of the AFP test results, as the test needs to be adjusted for maternal weight, age, ethnicity, and gestational age.

Choice D is wrong because fetal demise (death) can also cause high levels of AFP in the maternal blood, as the AFP from the dead fetus can leak into the amniotic fluid and then into the maternal blood.

Normal ranges of AFP in pregnant women vary depending on the gestational age and the method of measurement.

Generally, normal levels of AFP are below 10 ng/ml in nonpregnant adults and below 2.5 MoM in pregnant women.

A. The client has Rh-negative blood type. B. The client has a history of preterm labor. C. The client has a history of gestational diabetes. D. The client has a history of placenta previa

Correct Answer is D

Explanation

The correct answer is choice D. The client has a history of placenta previa.

Placenta previa is a condition where the placenta covers all or part of the cervix, blocking the baby’s exit from the uterus.

This can cause severe bleeding during pregnancy and delivery and increase the risk of complications for both the mother and the baby.

Therefore, the nurse should report this condition to the provider before performing an amniocentesis.

Choice A is wrong because having Rh-negative blood type is not a contraindication for amniocentesis.

However, the client may need an injection of Rh immunoglobulin after the procedure to prevent Rh sensitization.

Choice B is wrong because having a history of preterm labor is not a contraindication for amniocentesis.

However, the client may need to be monitored closely for signs of preterm labor after the procedure.

Choice C is wrong because having a history of gestational diabetes is not a contraindication for amniocentesis.

However, the client may need to have their blood glucose levels checked before and after the procedure.

Amniocentesis is a diagnostic procedure that involves removing and testing a small sample of amniotic fluid from the uterus for genetic or chromosomal conditions, such as Down syndrome, Edwards syndrome or Patau syndrome.

It can also be used to diagnose fetal infections, treat excess amniotic fluid, or test fetal lung maturity
