31. B – Rh isoimmunization occurs when Rh positive fetal blood cells cross into the maternal circulation and stimulate
maternal antibody production.

32. D – An Rh negative unsensitized woman should be given 300 mcg of RhoGAM at 28 weeks’ after an indirect.
33. C – An empty bladder and adequate hydration may help decrease or stop labor contractions.
34. B – Gravida refers to the number of times a client has been pregnant; para refers to the number of viable children

born. Therefore, the client who is gravida 4 para 2 has been pregnant four times and had two live-born children.
35. D – A woman with a history of diabetes has an increased risk for perinatal complications, including hypertension,

preeclampsia, and neonatal hypoglycemia.
36. C – Tocolytics are used to stop labor contractions. The most common adverse effect associated with the use of

these drugs is pulmonary edema.
37. C – Oxytocin is the hormone responsible for stimulating uterine contractions.
38. D – Only nutrients and waste products are transferred across the placenta. Blood exchange never occurs.

Complications and some medical procedures can cause an exchange to occur accidentally.
39. C – The weight of the pregnant uterus is sufficiently heavy to compress the vena cava, which could impair blood

flow to the uterus, possibly decreasing oxygen to the fetus.
40. D – Having the client lie down once during the day will allow her to concentrate on detecting fetal movement,

which can be reassuring. Additionally, when the mother is up and actively walking around, it tends to be soothing
to the fetus, resulting in sleep promotion.

41. C – Sitting down and putting up her feet at least once daily will promote venous return and therefore decrease
edema.

42. A – Eating small frequent meals will place less pressure on the esophageal sphincter, reducing the likelihood of
the regurgitation of stomach contents into the lower esophagus.

43. C – The incidence of preeclampsia in obese clients is about seven times more than that in pregnant nonobese
clients.

44. B – An NST is based on the theory that a healthy fetus will have transient fetal heart rate accelerations with fetal
movement.

45. B – Recommended fasting blood sugar levels in pregnant clients with diabetes are 60 to 90 mg/dl.
46. B – Of the techniques listed, the NST is the preferred antepartum heart rate screening test for pregnant clients

with diabetes. NSTs should be done at least twice weekly, starting at 32 weeks’ gestation, as fetal deaths in clients
with diabetes have been noted within 1 week of a reactive NST.

47. B – Regular uterine contractions (every 10 minutes or more) along with cervical dilation change before 36 weeks
is considered preterm labor.

48. C – Iron-deficiency anemia accounts for approximately 95% of anemia in pregnancy.
49. C – Diagnosis of the specific type of thalassemia is achieved by hemoglobin electrophoresis. This test detects

high levels of hemoglobin A2 or F.
50. B – Adolescent clients are at risk for delivering low-birth-weight neonates not macrosomic neonates.
