A nurse is collecting data from a client during their first prenatal visit. The nurse should identify which of the following findings as a risk factor for gestational diabetes mellitus?
Maternal age of 21 years.
Fasting blood glucose of 72 mg/dL.
Previous newborn weighing 4.8 kg.
Prepregnancy BMI of 23.
The Correct Answer is C
Choice A rationale
Maternal age of 21 years is not considered a significant risk factor for gestational diabetes. Typically, advanced maternal age (35 years or older) is considered a risk factor due to changes in insulin resistance that occur with age.
Choice B rationale
A fasting blood glucose of 72 mg/dL is within the normal range and does not indicate a risk for gestational diabetes. Gestational diabetes is usually diagnosed with fasting blood glucose levels higher than 95 mg/dL.
Choice C rationale
Previous newborn weighing 4.8 kg is a significant risk factor for gestational diabetes. Having a macrosomic (large) baby in a previous pregnancy is linked with an increased risk of developing gestational diabetes in subsequent pregnancies.
Choice D rationale
A prepregnancy BMI of 23 is within the normal range (18.5-24.9) and does not increase the risk of gestational diabetes. Higher BMI levels, particularly above 25, are associated with an increased risk.

Correct Answer is A
Explanation
Choice A rationale
Positioning the newborn's car seat at a 45° angle helps to maintain an open airway and reduces the risk of the baby's head falling forward, which can obstruct breathing.
Choice B rationale
Placing the car seat in a forward-facing position is incorrect for a newborn. Newborns and infants should always be placed in a rear-facing car seat to protect their head, neck, and spine in the event of a crash.
Choice C rationale
Placing a rolled blanket behind the newborn's neck is not recommended as it can alter the position of the head and neck, potentially compromising the airway. Proper positioning is crucial to ensure safety and comfort.
Choice D rationale
The retainer clip should be positioned at the level of the newborn's armpits, not the umbilicus. Proper placement of the retainer clip ensures that the harness is secure and reduces the risk of injury in a collision.
Correct Answer is B
Explanation
Choice A rationale
Disabling the driver-side airbags is not advisable as airbags provide crucial protection in the event of a collision. Proper seating position is a safer alternative.
Choice B rationale
Moving the seat as far away as possible from the steering wheel reduces the risk of injury from airbag deployment and allows ample space for the growing abdomen, providing better safety for both mother and baby.
Choice C rationale
Wearing the lap belt high across the abdomen is incorrect and dangerous as it can cause injury to the fetus. The belt should be low across the hips.
Choice D rationale
Placing the shoulder harness across the gravid uterus is incorrect. The harness should go between the breasts and to the side of the belly, not across it, to avoid compression injuries in the event of a crash.
