A nurse is preparing a client for a Contraction Stress Test (CST).
Which method can be used to induce uterine contractions during the test?
Nipple stimulation.
Intravenous oxytocin infusion.
Administering oral medications.
Applying warm compresses to the abdomen.
The Correct Answer is B
This method can be used to induce uterine contractions during the test by stimulating the uterus with a hormone that causes contractions.
Oxytocin is also the hormone that naturally triggers labor contractions.
Choice A is wrong because nipple stimulation can also induce contractions, but it is not as reliable or controllable as oxytocin infusion.
Choice C is wrong because oral medications are not used to induce contractions during a CST.
Some medications may interfere with the test results or cause side effects.
Choice D is wrong because applying warm compresses to the abdomen does not induce contractions.
It may help with pain relief or relaxation, but it does not affect the uterus.
Normal ranges for uterine contractions during a CST are three contractions in 10 minutes, each lasting 40 to 60 seconds.
Normal ranges for fetal heart rate during a CST are 110 to 160 beats per minute, with no decelerations after contractions.

Correct Answer is C
Explanation
. 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 B
Explanation
This test can detect genetic disorders.
Chorionic villus sampling (CVS) is a prenatal test that involves taking a sample of tissue from the placenta to test for chromosomal abnormalities and certain other genetic problems.
The placenta is a structure in the uterus that provides blood and nutrients from the mother to the fetus.
Choice A is wrong because CVS does not provide information on neural tube defects, such as spina bifida.
For this reason, women who undergo CVS also need a follow-up blood test between 16 to 18 weeks of their pregnancy to screen for neural tube defects.
Choice C is wrong because CVS can detect chromosomal abnormalities, but not all chromosomal abnormalities are genetic disorders.
For example, Down syndrome is a chromosomal abnormality caused by an extra copy of chromosome 21, but it is not inherited from the parents.
Choice D is wrong because CVS cannot detect Rh sensitization, which is a condition where the mother’s immune system produces antibodies against the fetus’s blood type.
Rh sensitization can be detected by a blood test that measures the level of antibodies in the mother’s blood.
