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%. .

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 C

Explanation

Choice A rationale

G4T1 P1 A1 L2 implies the client has been pregnant 4 times, with 1 term birth, 1 preterm birth, 1 abortion, and 2 living children. This does not include the correct number of pregnancies or abortions for this client.

Choice B rationale

G5T2 P0 A2 L2 indicates 5 pregnancies, 2 term births, no preterm births, 2 abortions, and 2 living children. This does not correctly account for the preterm birth and abortion history provided.

Choice C rationale

G5T1 P1 A2 L2 is the correct answer, as it denotes 5 pregnancies (including the current one), 1 term birth, 1 preterm birth, 2 abortions, and 2 living children, aligning with the client's history.

Choice D rationale

G5T1 P1 A1 L3 indicates 5 pregnancies, 1 term birth, 1 preterm birth, 1 abortion, and 3 living children. The client has only 2 living children, so this is incorrect.

A. The fetal heartbeat can be heard via Doppler by 4 weeks of pregnancy. B. The fetal heartbeat can be heard by external Doppler around 10-12 weeks of pregnancy. C. You will first feel your baby move in week 24 of pregnancy. D. The heart formation begins in week 5 of pregnancy and we can hear it by Doppler at 6 weeks.

Correct Answer is B

Explanation

Choice A rationale

The fetal heartbeat cannot typically be heard via Doppler as early as 4 weeks of pregnancy. At this stage, the heart is still developing, and it is too soon for external detection with a Doppler device.

Choice B rationale

The fetal heartbeat is generally detectable by an external Doppler device around 10-12 weeks of pregnancy. This is the period when the heartbeat is strong enough to be picked up by the device.

Choice C rationale

Feeling the baby move, known as "quickening," typically occurs around 18-24 weeks of pregnancy, not 6 weeks. This sensation is different from hearing the heartbeat.

Choice D rationale

While the heart begins to form around week 5, it is not detectable by Doppler at 6 weeks. The technology does not have the sensitivity to detect such an early heartbeat externally.
