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 A
Explanation
The correct answer is choice A. Notify the health care provider immediately.
This is because cramping and vaginal bleeding 24 hours after amniocentesis are signs of possible complications, such as injury to the baby or mother, leaking of amniotic fluid, infection, Rh sensitization, preterm labor, or miscarriage.
These complications are rare, but they can be serious and require immediate medical attention.
Choice B is wrong because administering pain medication to the patient does not address the underlying cause of the cramping and bleeding, and may delay seeking help.
Choice C is wrong because encouraging the patient to rest and elevate her legs may not prevent further complications, and may also delay seeking help.
Choice D is wrong because offering emotional support and reassurance to the patient is not enough to ensure the safety of the baby and the mother, and may give a false sense of security.
Normal ranges for amniocentesis are:
No chromosomal defects detected in the fetus and no abnormal proteins present in amniotic fluid
No signs of infection or other illness in the baby
Fetal lungs mature enough for birth if delivery is planned sooner than 39 weeks
Correct Answer is A
Explanation
A Doppler ultrasound blood flow analysis measures the velocity of blood flow in the uterine and fetal vessels.
This test can help assess the fetal well-being and oxygenation in cases of intrauterine growth restriction (IUGR).
Choice B is wrong because the amount of amniotic fluid in the uterine cavity is measured by ultrasound, not Doppler.
Choice C is wrong because the pressure of blood flow in the umbilical cord is not directly measured by Doppler, but rather inferred from the resistance index or pulsatility index.
Choice D is wrong because the oxygen saturation level of fetal blood is not measured by Doppler, but rather by fetal scalp sampling or pulse oximetry.
