A nurse is observing fetal breathing movements on an ultrasound for a client who is undergoing a biophysical profile (BPP).
The nurse should document how many points for this variable if the fetus has at least one episode of breathing lasting for 20 seconds within a 30-minute period?
0 points.
1 point.
2 points.
3 points.
The Correct Answer is C
According to the ACOG guidelines on antepartum fetal surveillance, one of the components of the biophysical profile is fetal breathing movements, which are scored as 2 points if there is one or more episodes of rhythmic fetal breathing movements of 30 seconds or more within 30 minutes.
Choice A is wrong because 0 points are given for absent or no breathing episode for ≥30 seconds within a 30 minute observation period.
Choice B is wrong because there is no 1 point score for this variable.
Choice D is wrong because there is no 3 point score for this variable.
The maximum score for each variable is 2 points.

Correct Answer is B
Explanation
There are no known risks or complications for the pregnant person or the fetus.
Prenatal ultrasound is a safe and noninvasive procedure that uses sound waves to create images of the fetus and the placenta.
It does not use radiation or harm the fetal tissues.
Choice A is wrong because ultrasound does not cause harm to the fetus.
There is no evidence that ultrasound has any adverse effects on fetal development, growth, or health.
Choice C is wrong because pregnant individuals do not need to avoid ultrasound due to potential radiation exposure.
Ultrasound does not involve radiation, unlike x-rays or CT scans.
Choice D is wrong because ultrasound does not lead to miscarriage or preterm labor.
Ultrasound is not associated with any increased risk of pregnancy complications, such as miscarriage, preterm labor, or birth defects.
Correct Answer is A
Explanation
This finding indicates that the umbilical cord is being compressed, which can reduce the blood flow and oxygen supply to the fetus.
Variable decelerations are abrupt decreases in the fetal heart rate (FHR) that vary in shape, duration, and degree of fall below the baseline.
They are seen as W- or U-shaped waves on the monitor.
Choice B is wrong because fetal hypoxia is not indicated by variable decelerations, but by late decelerations, which are gradual decreases in the FHR that begin after the peak of the contraction and return to baseline after the contraction ends.
Late decelerations are associated with uteroplacental insufficiency, which means that the placenta is not delivering enough oxygen to the fetus.
Choice C is wrong because normal placental function is not indicated by variable decelerations, but by reassuring FHR patterns, such as moderate variability (6 to 25 beats per minute) and accelerations (increases in the FHR above the baseline).
Normal placental function ensures adequate fetal oxygenation and well-being.
Choice D is wrong because adequate fetal oxygenation is not indicated by variable decelerations, but by reassuring FHR patterns, such as moderate variability and accelerations.
Adequate fetal oxygenation means that the fetus is not experiencing hypoxia or distress.
Normal ranges for FHR are 110 to 160 beats per minute at term and 120 to 160 beats per minute before term.
Normal ranges for uterine contractions are 2 to 5 contractions in 10 minutes, lasting less than 90 seconds each.
