A nurse is performing an abdominal ultrasound for a client who is at 28 weeks of gestation.
The nurse should instruct the client to do which of the following before the procedure?
Drink several glasses of water.
Empty her bladder completely.
Lie on her right side
Fast for at least 4 hours.
The Correct Answer is A
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 D
Explanation
The correct answer is choice D. The client has a history of placenta previa.
Placenta previa is a condition where the placenta covers all or part of the cervix, blocking the baby’s exit from the uterus.
This can cause severe bleeding during pregnancy and delivery and increase the risk of complications for both the mother and the baby.
Therefore, the nurse should report this condition to the provider before performing an amniocentesis.
Choice A is wrong because having Rh-negative blood type is not a contraindication for amniocentesis.
However, the client may need an injection of Rh immunoglobulin after the procedure to prevent Rh sensitization.
Choice B is wrong because having a history of preterm labor is not a contraindication for amniocentesis.
However, the client may need to be monitored closely for signs of preterm labor after the procedure.
Choice C is wrong because having a history of gestational diabetes is not a contraindication for amniocentesis.
However, the client may need to have their blood glucose levels checked before and after the procedure.
Amniocentesis is a diagnostic procedure that involves removing and testing a small sample of amniotic fluid from the uterus for genetic or chromosomal conditions, such as Down syndrome, Edwards syndrome or Patau syndrome.
It can also be used to diagnose fetal infections, treat excess amniotic fluid, or test fetal lung maturity
Correct Answer is C
Explanation
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.
