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 A
Explanation
Choice A rationale
"You will be tested again for GBS at about 36 weeks of gestation.”. This is correct because retesting for GBS at 35-37 weeks of gestation is standard practice to identify colonization status before delivery, which helps in planning intrapartum antibiotic prophylaxis.
Choice B rationale
"If you test positive for GBS, the provider will need to perform a cesarean birth.”. This is incorrect because GBS colonization is not an indication for cesarean delivery. The primary intervention is antibiotic administration during labor to prevent neonatal infection.
Choice C rationale
"You will take an antibiotic during the last 2 weeks of pregnancy to avoid transferring GBS to your baby.”. This is incorrect because antibiotics are given intrapartum (during labor) to prevent GBS transmission, not during the last weeks of pregnancy.
Choice D rationale
"This infection can cause your baby to experience hearing loss at birth.”. This is incorrect because GBS infection primarily causes sepsis, pneumonia, and meningitis in neonates, not hearing loss.
Correct Answer is D
Explanation
Choice A rationale
An apical pulse of 66/min is within the normal range and not indicative of postpartum hemorrhage, which would typically cause an elevated heart rate due to blood loss.
Choice B rationale
A temperature of 38.3°C (101°F) could indicate infection or inflammation but is not a direct sign of postpartum hemorrhage, which primarily involves significant blood loss.
Choice C rationale
Blood pressure of 156/80 mm Hg is elevated but not directly indicative of postpartum hemorrhage, which would typically result in a drop in blood pressure due to loss of blood volume.
Choice D rationale
A respiratory rate of 32/min is significantly elevated and can be a compensatory response to hypovolemia from postpartum hemorrhage. This response occurs as the body tries to increase oxygen delivery due to blood loss.
