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 B

Explanation

Choice A rationale

Monitoring the newborn's blood pressure does not directly address symptoms like diaphoresis, jitteriness, and lethargy. These symptoms indicate an immediate need to check blood glucose levels for hypoglycemia.

Choice B rationale

Obtaining blood glucose by heel stick is the correct step because diaphoresis, jitteriness, and lethargy in a newborn are classic signs of hypoglycemia. Timely detection and correction of blood glucose levels are critical.

Choice C rationale

Placing the newborn in a radiant warmer might help maintain body temperature but does not address the root cause of the symptoms, which is likely hypoglycemia.

Choice D rationale

Initiating phototherapy is used to treat jaundice (high bilirubin levels) and is not indicated for managing symptoms of hypoglycemia like diaphoresis, jitteriness, and lethargy.

Correct Answer is ["A","B","C","D","G"]

Explanation

Choice A: Respiratory assessment

The newborn is exhibiting signs of respiratory distress, such as mild grunting, nasal flaring, and intermittent retractions. These symptoms indicate potential respiratory issues that need immediate attention.

Choice B: Hemoglobin

The newborn's hemoglobin level is 9 g/dL, which is below the normal range of 14 to 24 g/dL2. This indicates anemia, which can affect the baby's oxygen-carrying capacity and overall health.

Choice C: Serum glucose

The newborn's serum glucose level is 38 mg/dL, which is below the normal range of 40 to 45 mg/dL2. Hypoglycemia in newborns can lead to serious complications if not addressed promptly.

Choice D: Heart rate

The newborn's heart rate is 180 beats per minute, which is above the normal range for a newborn (normal range: 120-160 beats per minute)2. This tachycardia could be a response to stress or an underlying condition that needs evaluation.

Choice G: Hematocrit

The newborn's hematocrit level is 35%, which is below the normal range of 44% to 64%2. This further supports the presence of anemia and the need for intervention2
