A nurse is educating a pregnant client about the Contraction Stress Test (CST).
Which statement accurately describes a negative CST?
No contractions were induced during the test.
Late decelerations of the FHR were observed with at least 50% of contractions.
The FHR remained stable throughout the test.
The client experienced mild uterine cramping during the tes.
The Correct Answer is C
This means that the baby’s heart rate did not slow down after the contractions induced by oxytocin, which is a sign of normal fetal well-being.
A negative CST is normal and desirable.
Choice A is wrong because no contractions were induced during the test.
This means that the test was inconclusive and could not assess the baby’s response to stress.
Choice B is wrong because late decelerations of the FHR were observed with at least 50% of contractions.
This means that the baby’s heart rate slowed down and stayed slow after the contractions, which is a sign of fetal distress and hypoxia.
A positive CST is abnormal and concerning.
Choice D is wrong because the client experienced mild uterine cramping during the test.
This is not a relevant factor for interpreting the CST results, which depend on the FHR patterns.
Uterine cramping can be a side effect of oxytocin administration or nipple stimulation.

Correct Answer is A
Explanation
An equivocal CST indicates late decelerations of the FHR with less than 50% of contractions.
This means that the fetus may have some degree of hypoxia or distress, but not enough to warrant immediate delivery.
An equivocal CST may also result from hyperstimulation of the uterus, which can cause excessive contractions and reduce blood flow to the placenta.
Choice B is wrong because late decelerations of the FHR with at least 50% of contractions is a positive CST, which indicates a high risk of fetal death due to hypoxia and is a contraindication to labor.
Choice C is wrong because no late decelerations of the FHR during contractions is a negative CST, which indicates a good fetal wellbeing and tolerance of labor.
Choice D is wrong because variable decelerations of the FHR with or without contractions are not related to uterine activity and may indicate cord compression or other fetal problems.
Variable decelerations are not used to interpret CST results.
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.
