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
Accelerations are increases in the fetal heart rate (FHR) above the baseline, typically in response to fetal movement or uterine contractions. They indicate a healthy, well-oxygenated
fetus and are not consistent with the described pattern of decelerations.
Choice B rationale
Late decelerations are characterized by a gradual decrease in FHR that begins after the contraction has started, with the lowest point of the deceleration (nadir) occurring after the
peak of the contraction. They are associated with uteroplacental insufficiency and fetal hypoxia, which is not described in the scenario.
Choice C rationale
Early decelerations are a gradual decrease in FHR that mirrors the contraction, starting with the contraction and returning to baseline as the contraction ends. The nadir of the
deceleration occurs at the peak of the contraction, which fits the pattern described.
Choice D rationale
Variable decelerations are abrupt decreases in FHR that can occur at any time during the contraction cycle, usually due to umbilical cord compression. They are not uniform in
relation to contractions and can vary in duration, depth, and timing, unlike the described pattern.
Correct Answer is C
Explanation
Choice A rationale
Assessing the client's blood pressure can help determine if there is a significant loss of blood and consequent hypotension. However, it is not the immediate first action to manage
heavy bleeding postpartum.
Choice B rationale
Assessing the bladder for distention is crucial as a full bladder can interfere with uterine contraction, potentially leading to increased bleeding. But, it isn't the first priority compared to
addressing the immediate bleeding.
Choice C rationale
Massaging the client's fundus is the priority action in this case. It helps to contract the uterus, thereby reducing bleeding. Uterine atony is the most common cause of postpartum
hemorrhage, and fundal massage is the first intervention to manage it.
Choice D rationale
Preparing to administer a prescription may be necessary, especially if uterotonics are required. However, this is a subsequent step after attempting to control the bleeding through
fundal massage.
