A client is scheduled for an abdominal ultrasound in two weeks to assess fetal growth and development during pregnancy.

Which of these statements made by the client indicates that further teaching is needed?

“I will drink plenty of fluids before my appointment.”

“I will eat a light meal before my appointment.”

“I will wear comfortable clothing.”

“I will arrive at my appointment with a full bladder."

Answer and Explanation

The Correct Answer is B

The client should not eat a light meal before an abdominal ultrasound because it can interfere with the quality of the images.

The client should fast for 8 to 12 hours before the procedure.

Some additional information about the other choices are:

Choice A is correct.

The client should drink plenty of fluids before an appointment for an abdominal ultrasound because it helps to fill the bladder and push the uterus up for better visualization.

Choice C is correct.

The client should wear comfortable clothing that can be easily removed or lifted up to expose the abdomen.

Choice D is correct.

The client should arrive at the appointment with a full bladder because it acts as an acoustic window and improves the quality of the ultrasound images.

Normal ranges for fetal growth and development during pregnancy vary depending on the gestational age, but some general parameters are:

Fetal heart rate: 110 to 160 beats per minute

Biparietal diameter: 2.4 to 9.5 cm

Crown-rump length: 0.8 to 8.4 cm

Femur length: 1.0 to 7.8 cm

Abdominal circumference: 9.4 to 35.6 cm

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.

A. Screening for neural tube defects. B. Assessing placental function. C. Determining fetal gender D. Diagnosing chromosomal abnormalities

Correct Answer is A

Explanation

An alpha-fetoprotein test (AFP) is a blood test that measures the amount of AFP present in blood.

It’s usually part of what’s called a triple screen or quad screen in the second trimester of pregnancy.

The yolk sac, GI tract, and liver of an unborn baby produce AFP.

It then circulates through the fetal and maternal blood.

High levels of AFP in pregnant people can indicate that the baby has a neural tube defect, such as spina bifida or anencephaly.

Choice B is wrong because assessing placental function is not the primary purpose of an AFP test.

However, low levels of AFP can indicate problems with the placenta or the baby’s growth.

Choice C is wrong because determining fetal gender is not the primary purpose of an AFP test.

However, some genetic tests that use a sample of the baby’s DNA from the pregnant person’s blood can reveal the baby’s sex as early as 10 weeks of pregnancy.

Choice D is wrong because diagnosing chromosomal abnormalities is not the primary purpose of an AFP test.

However, an AFP test is usually part of a quad screen that also tests for other markers that can indicate the risk of chromosomal abnormalities, such as Down syndrome.
