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 C
Explanation
Choice A rationale
The placenta does not provide thermoregulation; that function is managed by maternal thermoregulation and the amniotic fluid which insulates the fetus.
Choice B rationale
Amniotic fluid cushions the fetus from maternal movements, not the placenta. The placenta's role is more focused on nutrient and waste exchange.
Choice C rationale
The placenta facilitates metabolic functions and gas exchange, supplying oxygen and nutrients to the fetus while removing carbon dioxide and waste products, ensuring fetal development.
Choice D rationale
The placenta doesn't provide a sterile environment. This is accomplished by the amniotic sac and amniotic fluid. The placenta connects the fetus to maternal blood supply, ensuring necessary exchanges for fetal growth.
Correct Answer is D
Explanation
Choice A rationale
Severe nausea and vomiting, known as hyperemesis gravidarum, are more commonly associated with high levels of human chorionic gonadotropin (hCG) and are not specific to
ectopic pregnancy.
Choice B rationale
While vaginal bleeding can occur in an ectopic pregnancy, it is usually not a large amount. The bleeding in ectopic pregnancy tends to be light and irregular.
Choice C rationale
Uterine enlargement greater than expected for gestational age is typically associated with conditions like molar pregnancy, not ectopic pregnancy, as the pregnancy is located outside
the uterus.
Choice D rationale
Unilateral, cramp-like abdominal pain is a classic symptom of ectopic pregnancy as the fertilized egg implants outside the uterus, most commonly in a fallopian tube, causing
localized pain.
