A nurse is caring for a client who is scheduled for an amniocentesis at 16 weeks gestation.
Which of the following should the nurse report to the provider?
The client’s bladder is full.
The client’s uterus is above the symphysis pubis
The client’s cervix is dilated
The client’s fundal height measures 20 cm
The Correct Answer is C
. The client’s cervix is dilated.
This indicates that the client may be in preterm labor, which is a contraindication for amniocentesis.
Amniocentesis is a procedure that involves inserting a needle into the amniotic sac to obtain a sample of amniotic fluid for genetic testing or other purposes.
It is usually performed between 15 and 20 weeks of gestation.
Choice A is wrong because the client’s bladder should be full for amniocentesis.
This helps to push the uterus upward and away from the bladder, reducing the risk of injury and making it easier to visualize the fetus and the needle.
Choice B is wrong because the client’s uterus should be above the symphysis pubis at 16 weeks of gestation.
This is a normal finding and does not affect the procedure.
Choice D is wrong because the client’s fundal height should measure around 16 cm at 16 weeks of gestation.
A fundal height of 20 cm may indicate a large for gestational age fetus, multiple gestation, or polyhydramnios (excess amniotic fluid), but these are not absolute contraindications for amniocentesis.
However, they may require further evaluation and adjustment of the technique.

Correct Answer is A
Explanation
“The patient should have a full bladder for a transabdominal US and an empty bladder for a transvaginal US.”1 This is because a full bladder helps to lift the uterus and improve the visibility of the pelvic organs in a transabdominal US, while an empty bladder prevents distortion of the image in a transvaginal US.
Choice B is wrong because tight-fitting clothing is not necessary and lying prone on an examination table is uncomfortable and may interfere with the insertion of the vaginal probe.
Choice C is wrong because loose-fitting clothing is not necessary and lying supine on an examination table may cause supine hypotension syndrome in pregnant women.
Choice D is wrong because loose-fitting clothing is not necessary and lying prone on an examination table is uncomfortable and may interfere with the insertion of the vaginal probe.
Correct Answer is A
Explanation
“I will have sensors placed on my abdomen to monitor the FHR and uterine contractions.” This statement indicates the client understands the test procedure of a CST, which is a test that triggers contractions and registers how the baby’s heart reacts.
The test is done by placing two sensor belts around the abdomen, one to measure the baby’s heartbeat and the other to measure contractions.
The client may receive oxytocin through an IV to induce contractions.
Choice B is wrong because the client does not need to fast for 24 hours before the test.
There is no evidence that fasting is required for a CST.
Choice C is wrong because the client will not be sedated during the test.
Sedation is not necessary for a CST and may interfere with the results.
Choice D is wrong because the client does not need to drink plenty of fluids before the test.
There is no evidence that drinking fluids is required for a CST.
