During a CST, the nurse observes variable decelerations of the FHR with or without contractions.
What does this finding indicate?
Cord compression
Fetal hypoxia
Normal placental function
Adequate fetal oxygenation
The Correct Answer is A
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.

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
“The patient should have a full bladder for a transabdominal US and an empty bladder for a transvaginal US.”1 This is because a full bladder helps to lift the uterus and improve the visibility of the pelvic organs in a transabdominal US, while an empty bladder prevents distortion of the image in a transvaginal US.
Choice B is wrong because tight-fitting clothing is not necessary and lying prone on an examination table is uncomfortable and may interfere with the insertion of the vaginal probe.
Choice C is wrong because loose-fitting clothing is not necessary and lying supine on an examination table may cause supine hypotension syndrome in pregnant women.
Choice D is wrong because loose-fitting clothing is not necessary and lying prone on an examination table is uncomfortable and may interfere with the insertion of the vaginal probe.
