A client at 28-weeks gestation whose hemoglobin level is 10.7 g/dL (107 g/L) and hematocrit is 32.3% (0.323 volume fraction), tells the nurse that she eats plenty of green vegetables.
When the client asks the nurse how the pregnancy might affect the laboratory findings, which information should the nurse provide?

Increasing intake of protein might improve these values.

Plasma volume increases, making the blood count appear low.

Almost all women at 28-weeks gestation have anemia.

It might be necessary to take an iron supplement twice daily.

Answer and Explanation

The Correct Answer is B

Choice A rationale
While protein is an essential nutrient for overall health and wellbeing, increasing protein intake alone is unlikely to significantly improve hemoglobin levels. Hemoglobin is a protein in red blood cells that carries oxygen, and its production depends on having enough iron, vitamin B12, and folic acid, not just protein.
Choice B rationale
During pregnancy, the volume of blood in a woman’s body increases to support the growing fetus. This increase in blood volume can dilute the blood, which can lead to a decrease in the concentration of red blood cells and hemoglobin, a condition known as physiological anemia of pregnancy. This is a normal part of pregnancy and is typically not a cause for concern.
Choice C rationale
While it’s true that many women experience changes in their hemoglobin levels during pregnancy, it’s not accurate to say that almost all women at 28-weeks gestation have anemia. Anemia is defined as a level of hemoglobin that’s lower than normal, and the normal range can vary. However, it’s important to note that the normal range for hemoglobin does decrease during pregnancy.
Choice D rationale
Iron is a key component of hemoglobin, and iron deficiency is a common cause of anemia. If a pregnant woman’s hemoglobin levels are low, taking an iron supplement might help increase these levels. However, it’s important to talk to a healthcare provider before starting any new medication or supplement.

Second doses of vaccines are generally not given to children who have had allergic reactions to the first dose.
Choice D rationale
Breastfeeding does not interfere with the effectiveness of vaccines. In fact, breastfeeding can enhance the response to certain vaccine antigens.

Correct Answer is ["0.72"]

Explanation

Step 1 is to calculate the total amount of oxytocin in the IV bag. This is done by multiplying the total volume of the bag by the concentration of oxytocin. In this case, the bag contains 5 units of oxytocin in 500 mL, so the concentration is 5 units ÷ 500 mL = 0.01 units/mL.

Step 2 is to convert the prescribed dose from milliunits/min to units/hour. There are 1000 milliunits in a unit and 60 minutes in an hour, so 12 milliunits/min = 12 ÷ 1000 units/min = 0.012 units/min. Then, 0.012 units/min × 60 min/hour = 0.72 units/hour.

Step 3 is to calculate the infusion rate in mL/hour. This is done by dividing the prescribed dose in units/hour by the concentration of oxytocin in units/mL. So, 0.72 units/hour ÷ 0.01 units/mL = 72 mL/hour. Therefore, the nurse should set the infusion pump to 72 mL/hour.
