A nurse is collecting data from a newborn who was delivered at 40 weeks of gestation. Which of the following is an expected finding when eliciting reflexes from the newborn?
The newborn's legs flex at the knees and hips when pressure is applied to the soles of the newborn's feet.
The newborn closes their eyes and keeps them closed when tapped on the forehead.
The newborn's fingers curl around the nurse's finger when placed in the newborn's palm.
The newborn turns their head away from the stimulus when their cheek is touched.
The Correct Answer is C
Choice A rationale
The newborn's legs flexing at the knees and hips when pressure is applied to the soles indicates the stepping reflex, an expected response.
Choice B rationale
Newborns do not typically keep their eyes closed when tapped on the forehead; this is not an expected reflex response.
Choice C rationale
The palmar grasp reflex, where the newborn's fingers curl around the nurse's finger, is an expected and normal finding in newborns, indicating healthy neurological function.
Choice D rationale
The rooting reflex, where the newborn turns their head when their cheek is touched, is expected and demonstrates feeding readiness and normal neural development. .

Correct Answer is A
Explanation
Choice A rationale
Testing for GBS at around 36 weeks of gestation is standard practice to identify carriers and prevent neonatal GBS infections through intrapartum antibiotic prophylaxis if necessary.
Choice B rationale
Cesarean birth is not indicated solely based on a positive GBS status. The primary intervention is intrapartum antibiotic prophylaxis to reduce the risk of neonatal infection.
Choice C rationale
Routine antibiotic administration during the last weeks of pregnancy is not standard practice; antibiotics are given during labor if GBS is present to prevent transmission to the baby.
Choice D rationale
GBS infection does not cause hearing loss in newborns. The primary concern is neonatal sepsis, pneumonia, or meningitis, not hearing loss.
Correct Answer is A
Explanation
Choice A rationale
Respiratory rate of 10/min is a critical adverse effect, indicating potential respiratory depression due to magnesium sulfate, a serious and life-threatening condition requiring immediate intervention.
Choice B rationale
Urine output of 160 mL in 4 hours is lower than expected but not immediately life-threatening. It needs monitoring but is not as critical as respiratory rate.
Choice C rationale
Diaphoresis, or excessive sweating, can be a side effect of magnesium sulfate but is not life-threatening. It warrants attention but does not require immediate reporting.
Choice D rationale
Nausea is a common, less severe side effect of magnesium sulfate that does not indicate an urgent situation.
