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 B

Explanation

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

A. No contractions were induced during the test. B. Late decelerations of the FHR were observed with at least 50% of contractions. C. The FHR remained stable throughout the test. D. The client experienced mild uterine cramping during the tes.

Correct Answer is C

Explanation

This means that the baby’s heart rate did not slow down after the contractions induced by oxytocin, which is a sign of normal fetal well-being.

A negative CST is normal and desirable.

Choice A is wrong because no contractions were induced during the test.

This means that the test was inconclusive and could not assess the baby’s response to stress.

Choice B is wrong because late decelerations of the FHR were observed with at least 50% of contractions.

This means that the baby’s heart rate slowed down and stayed slow after the contractions, which is a sign of fetal distress and hypoxia.

A positive CST is abnormal and concerning.

Choice D is wrong because the client experienced mild uterine cramping during the test.

This is not a relevant factor for interpreting the CST results, which depend on the FHR patterns.

Uterine cramping can be a side effect of oxytocin administration or nipple stimulation.
