A nurse is performing an abdominal ultrasound for a client who is at 28 weeks of gestation.

The nurse should instruct the client to do which of the following before the procedure?

Drink several glasses of water.

Empty her bladder completely.

Lie on her right side

Fast for at least 4 hours.

Answer and Explanation

The Correct Answer is A

The woman should drink several glasses of water before the abdominal ultrasound procedure.

This is because a full bladder helps to push the intestines away and improve the visibility of the uterus and the fetus.

Drinking water also helps to avoid gas buildup in the abdomen, which could interfere with the sound waves.

Choice B is wrong because emptying the bladder would make it harder to see the uterus and the fetus.

Choice C is wrong because lying on the right side would not affect the quality of the ultrasound image.

Choice D is wrong because fasting is not necessary for an abdominal ultrasound, unless instructed by the doctor for a specific reason.

Correct Answer is A

Explanation

This is because AFP levels vary according to the gestational age of the fetus, and reporting them as multiples of the median (MoM) allows for a standardized comparison.

Choice B is wrong because AFP results do not differentiate between neural tube defects and chromosomal abnormalities.

They only indicate an increased risk for these conditions, which need further testing to confirm.

Choice C is wrong because AFP results do not assess the risk of fetal demise or multiple gestation.

They only measure the amount of AFP in the maternal blood, which can be affected by various factors such as maternal weight, race, diabetes, and fetal anomalies.

Choice D is wrong because AFP results are reported as MoM regardless of factors such as maternal weight and race.

These factors are taken into account when calculating the MoM value, which adjusts for the expected variation in AFP levels among different populations.

Normal ranges for AFP MoM vary depending on the laboratory and the method used, but generally they are between 0.5 and 2.52.

Values above or below this range may indicate an increased risk for certain fetal conditions or complications.

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
