ATI Maternal Newborn III Questions
Extract:
A client with severe preeclampsia receiving magnesium sulfate
Question 1 of 5
Which compound would the nurse have readily available for a client who is receiving magnesium sulfate to treat severe preeclampsia?
Correct Answer: D
Rationale: Calcium gluconate reverses magnesium toxicity (e.g., respiratory depression), a risk with magnesium sulfate used for preeclampsia. Ferrous sulfate treats anemia, potassium chloride corrects hypokalemia, and calcium carbonate is an antacid, none addressing toxicity.
Extract:
A pregnant woman whose baby will have Down syndrome
Question 2 of 5
While talking with a pregnant woman who has undergone genetic testing, the woman informs the nurse that her baby will be born with Down syndrome. The nurse understands that Down syndrome is an example of:
Correct Answer: A
Rationale: Down syndrome is caused by trisomy 21, an extra chromosome 21, a numeric abnormality. Multifactorial inheritance involves genes and environment, X-linked affects males primarily, and deletions miss chromosome parts, none fitting Down syndrome.
Extract:
A pregnant client in her second trimester with a hemoglobin level of 11 g/dL
Question 3 of 5
A pregnant client in her second trimester has a hemoglobin level of 11 g/dL. The nurse interprets this as indicating
Correct Answer: A
Rationale: Hemodilution of pregnancy occurs as plasma volume increases more than red blood cell mass, lowering hemoglobin to 10.5-14 g/dL in the second trimester, which includes 11 g/dL. Multiple gestation may raise hemoglobin, weight gain doesn't affect it, and iron-deficiency anemia typically shows lower hemoglobin with symptoms like fatigue.
Extract:
A pregnant woman with oligohydramnios
Question 4 of 5
Assessment of a pregnant woman reveals oligohydramnios. The nurse would be alert for the development of which condition?
Correct Answer: B
Rationale: Oligohydramnios (low amniotic fluid) is linked to fetal anencephaly, where absent brain development reduces fetal urine, a fluid source. Maternal diabetes causes polyhydramnios, abruption affects bleeding, and neural tube defects don't directly reduce fluid.
Extract:
A client with Rh-negative blood and Rh-positive partner
Question 5 of 5
It is determined that a client's blood Rh is negative and her partner's is positive. To help prevent Rh isoimmunization, the nurse would expect to administer Rho(D) immune globulin at which time?
Correct Answer: C
Rationale: Rho(
D) immune globulin at 28 weeks and within 72 hours post-delivery prevents Rh isoimmunization effectively. Other schedules miss critical windows for blocking maternal antibody response.
