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 B
Explanation
Each of the five variables in a biophysical profile (BPP) is assigned a score of either 0 or 2 points, depending on whether it meets the criteria or not.
The five variables are:
Fetal breathing: 2 points if there is at least one episode of rhythmic breathing lasting at least 30 seconds within 30 minutes, 0 points otherwise.
Fetal movement: 2 points if there are at least three discrete body or limb movements within 30 minutes, 0 points otherwise.
Fetal tone: 2 points if there is at least one episode of extremity extension and subsequent return to flexion, 0 points otherwise.
Amniotic fluid volume: 2 points if there is a pocket of amniotic fluid measuring at least 2 cm in two perpendicular planes, 0 points otherwise.
Nonstress test: 2 points if there are at least two accelerations of fetal heart rate with or without fetal movement within 20 minutes, 0 points otherwise.
Choice A is wrong because each variable can have a score of either 0 or 2, not 0 or.
Choice C is wrong because there is no score of 1 for any variable.
Choice D is wrong because it is incomplete and does not provide the full range of possible scores.
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.
