A client is scheduled for an abdominal ultrasound in two weeks.
The client asks the nurse what they should do to prepare for the test.
What is the best response by the nurse?
“The patient should have a full bladder for a transabdominal US and an empty bladder for a transvaginal US.”.
“The patient should wear tight-fitting clothing and lie prone on an examination table.”.
“The patient should wear loose-fitting clothing and lie supine on an examination table.”.
“The patient should wear loose-fitting clothing and lie supine on an examination table.”.
The Correct Answer is C
The patient should wear loose-fitting clothing and lie supine on an examination table.
This is because loose-fitting clothing allows easy access to the abdomen and lying supine helps relax the abdominal muscles.
The patient should also avoid food and drinks for 8 to 12 hours before the test, as undigested food can interfere with the sound waves and affect the image quality.
Choice A is wrong because a full bladder is not necessary for an abdominal ultrasound, unless the patient is pregnant or has a pelvic condition.
A transvaginal ultrasound is a different type of ultrasound that uses a probe inserted into the vagina to examine the reproductive organs.
Choice B is wrong because tight-fitting clothing can restrict the movement of the ultrasound probe and make it harder to get a clear image.
Lying prone (on the stomach) can also tense up the abdominal muscles and obscure the organs.
Choice D is wrong because lying prone can have the same disadvantages as choice B. Additionally, wearing loose-fitting clothing does not mean that the patient can eat or drink anything before the test, as this can affect the results.

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.
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
