A nurse is reviewing the laboratory results for a client who is at 29 weeks of gestation and has a history of anemia.Which of the following results should the nurse identify and report as an indication of a prenatal complication?
BUN 25 mg/dL (10 to 20 mg/dL).
Hgb 10.2 mg/dL (11 to 16 mg/dL).
Fasting blood glucose 70 mg/dL (70 to 110 mg/dL).
Hct 32% (33 to 47%).
The Correct Answer is B
Choice A rationale
Elevated BUN levels (25 mg/dL) can indicate kidney dysfunction, dehydration, or high protein intake. However, it’s not directly related to a prenatal complication, though it still requires monitoring.
Choice B rationale
Hemoglobin (Hgb) of 10.2 mg/dL is below the normal range (11 to 16 mg/dL) and can indicate anemia. During pregnancy, anemia can lead to serious complications such as preterm birth and low birth weight, making this result significant.
Choice C rationale
A fasting blood glucose level of 70 mg/dL falls within the normal range (70 to 110 mg/dL) and does not indicate a complication. Thus, it is not concerning in the context of prenatal complications.
Choice D rationale
Hematocrit (Hct) of 32% is slightly below the normal range (33 to 47%), which can be common in pregnancy due to increased plasma volume. While monitoring is required, it’s not as critical as anemia.

Correct Answer is B
Explanation
Choice A rationale
During labor, the body experiences physiological stress, which typically causes an increase, not a decrease, in white blood cell (WBC) count. This increase is a normal response to stress.
Choice B rationale
Blood glucose levels can decrease during labor due to the energy expenditure and physiological demands of the process. This is why it is important to monitor glucose levels and provide necessary interventions if hypoglycemia occurs.
Choice C rationale
The respiratory rate generally increases during labor to meet the increased oxygen demands of the body. A decrease in respiratory rate is not expected during this time.
Choice D rationale
Body temperature may increase slightly during labor due to the physical exertion and metabolic activity involved. A decrease in temperature is not a typical finding during labor. .
Correct Answer is D
Explanation
Choice A rationale
Taking iron supplements with milk is not advised because calcium in milk can interfere with the absorption of iron, reducing its effectiveness.
Choice B rationale
Doubling the dose of iron supplements if a dose is missed is not recommended because it can cause gastrointestinal issues and toxicity. It's better to just continue with the regular dosing schedule.
Choice C rationale
Consuming 29 grams of fiber daily is a good practice for overall health, but it does not directly aid in iron absorption. Fiber can actually bind to iron and decrease its absorption in the intestines.
Choice D rationale
Vitamin C enhances the absorption of non-heme iron (found in supplements) by converting it into a more absorbable form. Taking vitamin C with iron supplements increases their effectiveness, making this statement correct.
