A nurse is interpreting the results of a biophysical profile (BPP) for a client who is at 34 weeks of gestation.
The nurse should understand that each of the five variables is assigned a score of how many points?
0 or.
0 or.
1 or.
1 or.
The Correct Answer is B
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
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.
