A nurse is reinforcing teaching about safety precautions to take when driving a car with a client who is in the first trimester of pregnancy. Which of the following instructions should the nurse include in the teaching?
Disable the vehicle's driver-side airbags.
Move the seat as far away as possible from the steering wheel.
Wear the lap belt high across the abdomen.
Place the shoulder harness across the gravid uterus.
The Correct Answer is B
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.

Correct Answer is C
Explanation
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
A single crease in the palm, known as a simian crease, is a common characteristic seen in infants with trisomy 21 (Down syndrome) due to the unique hand structure associated with this condition.
Choice B rationale
A notch in the lip, such as a cleft lip, is not commonly associated with trisomy 21 and is more typically related to other genetic conditions or environmental factors during development.
Choice C rationale
An inversion of the foot, such as clubfoot, is not a specific characteristic of trisomy 21. This condition is more often seen in other congenital anomalies not related to Down syndrome.
Choice D rationale
Extra digits on the hand, or polydactyly, is not commonly associated with trisomy 21 but can be seen in other genetic disorders. Trisomy 21 has more specific physical features like the simian crease.
