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?

A.

10% - 15%.

B.

20% - 30%.

C.

40% - 50%.

D.

65% - 75%. .

Answer and Explanation

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

Explanation

Step 1 is: 12 mg ÷ 6 mg/ml.

Step 2 is: 12 ÷ 6 = 2 ml. Answer: 2 ml

Correct Answer is C

Explanation

Choice A rationale

Placenta formation begins shortly after implantation, but it continues to develop throughout the first trimester and into the early second trimester, making it less precise to attribute the

first 8 weeks solely to this process.

Choice B rationale

Fertilization occurs within the first week after ovulation, marking the beginning of pregnancy, but it is a singular event that happens prior to the developmental processes vulnerable to teratogens.

Choice C rationale

Organogenesis is the critical period during which the major organs and structures of the fetus form, typically occurring between the third and eighth weeks of gestation. This is the

time when the fetus is most susceptible to the effects of teratogens, which can cause congenital anomalies.

Choice D rationale

Implantation occurs approximately 6-10 days after fertilization, embedding the blastocyst into the uterine lining. While crucial, it is not the primary period when teratogenic effects are

most significant, as this happens during organogenesis.
