A client is concerned about needing a blood transfusion after delivery due to the blood loss in delivery. The nurse explains that blood volume increases during pregnancy. Which of the following is the correct percentage of increased blood volume during pregnancy that the nurse should explain to the client?
10% - 15%.
20% - 30%.
40% - 50%.
65% - 75%. .
The Correct Answer is C
Choice A rationale
A 10% to 15% increase in blood volume during pregnancy is too low compared to the average physiological changes that occur.
Choice B rationale
A 20% to 30% increase in blood volume is also below the expected range of increase during pregnancy.
Choice C rationale
Blood volume typically increases by 40% to 50% during pregnancy. This significant increase supports the demands of the growing fetus and placenta and prepares the mother's body for the blood loss that occurs during delivery.
Choice D rationale
A 65% to 75% increase is an overestimate. Such an extensive increase would be abnormal and is not typical in healthy pregnancies.

Correct Answer is ["A","B","C"]
Explanation
Choice A: Give betamethasone 12 mg IM now and repeat in 24 hr.
Rationale: Betamethasone is administered to accelerate fetal lung maturity in cases of preterm labor. Given the client's gestational age of 31 weeks, this intervention is appropriate to help reduce the risk of respiratory distress syndrome in the newborn.
Choice B: Begin loading dose of magnesium sulfate 9 g over 30 min.
Rationale: Magnesium sulfate is used for neuroprotection of the fetus in preterm labor to reduce the risk of cerebral palsy. The loading dose is typically given to achieve therapeutic levels quickly.
Choice C: Position the client in a lateral position.
Rationale: Positioning the client in a lateral position helps improve uteroplacental blood flow and can reduce the intensity of contractions, which is beneficial in managing preterm labor.
Correct Answer is D
Explanation
Choice A rationale
Administering the rubella vaccine during pregnancy, including the third trimester, is contraindicated due to the risk of live vaccine transmission to the fetus. It is not recommended at any stage of pregnancy.
Choice B rationale
Advising the client to get the vaccine during her next pregnancy attempt is partly correct but lacks the immediacy needed to ensure she is immune before the next pregnancy. The vaccine should be given postpartum.
Choice C rationale
Administering the vaccine immediately during pregnancy is contraindicated due to potential risks to the fetus. Rubella vaccines contain live virus, which can cause fetal harm if given during pregnancy.
Choice D rationale
It is safest to administer the rubella vaccine postpartum, prior to hospital discharge, to ensure the client has immunity before any future pregnancies. This timing prevents any risk to the current fetus and ensures future fetal protection. .
