A nurse is discussing the risks associated with a Contraction Stress Test (CST) with a pregnant client.
Which complication should the nurse mention?
Preterm labor.
Premature rupture of membranes.
Infection.
Bleeding.
The Correct Answer is A
A contraction stress test (CST) is a test that simulates labor contractions to see how the baby’s heart rate responds to the stress of uterine contractions.
The biggest risk of the test is that it may cause the pregnant person to go into labor before their due date.
Some possible explanations for the other choices are:
Choice B. Premature rupture of membranes.
This is a condition where the amniotic sac breaks before labor begins.
It can increase the risk of infection and cord prolapse, but it is not a direct complication of CST.
Choice C. Infection.
This is a possible risk of any invasive procedure, but CST is usually done with external fetal monitoring and oxytocin infusion, which do not require breaking the skin or entering the uterus.
Choice D. Bleeding.
This is a potential risk of CST for people who have placenta previa, a condition where the placenta covers the cervix and can detach during contractions.
However, CST is not recommended for people who have placenta previa or other conditions that increase the risk of uterine rupture or bleeding.

Correct Answer is A
Explanation
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 A
Explanation
A contraction stress test (CST) is performed near the end of pregnancy to determine how well the fetus will cope with the contractions of childbirth.
The aim is to induce contractions and monitor the fetus to check for heart rate abnormalities using a cardiotocograph.
A normal heartbeat is a good sign that the fetus will be healthy during labor.
Choice B is wrong because a CST does not measure maternal blood pressure.
Choice C is wrong because a CST does not assess placental function directly.
Choice D is wrong because a CST does not measure amniotic fluid volume.
Normal ranges for fetal heart rate are between 110 and 160 beats per minute.
Normal ranges for uterine contractions are between 2 and 5 contractions in 10 minutes, lasting less than 90 seconds each.
