A nurse is collecting data about reflexes from a newborn. Which of the following actions should the nurse take to elicit the newborn's Moro reflex?
Perform a sharp hand clap near the infant.
Turn the newborn's head quickly to one side.
Place a finger at the base of the newborn's toes.
Hold the newborn vertically, allowing one foot to touch the crib surface.
The Correct Answer is A
Choice A rationale:
The Moro reflex, also known as the startle reflex, is a normal reflex observed in newborns. To elicit this reflex, the nurse should perform a sharp hand clap or make a loud noise near the infant. This reflex is characterized by the baby's arms and legs extending outward, followed by a quick flexion, resembling a startle response. It is an important reflex to assess the newborn's neurological and motor development.
Choice B rationale:
Turning the newborn's head quickly to one side does not elicit the Moro reflex. This action may stimulate other reflexes, such as the tonic neck reflex, but it is not the appropriate method to assess the Moro reflex.
Choice C rationale:
Placing a finger at the base of the newborn's toes does not elicit the Moro reflex. This action is more related to testing the Babinski reflex, which involves the fanning and curling of the toes when the sole of the foot is stimulated.
Choice D rationale:
Holding the newborn vertically and allowing one foot to touch the crib surface does not elicit the Moro reflex. This action might elicit the stepping reflex, where the baby shows stepping movements as if walking when held in an upright position with their feet touching a surface.

Correct Answer is A
Explanation
Back to sleep.
Choice A rationale:
Placing a baby on their back to sleep is the most effective way to prevent flat spots on the back of their head. This sleeping position, recommended by pediatric experts, helps reduce the risk of sudden infant death syndrome (SIDS) while also minimizing pressure on any one part of the baby's head, thus decreasing the likelihood of developing flat spots.
Choice B rationale:
Taking the baby for walks does not directly address the prevention of flat spots on the back of the head. Although it is beneficial for the baby's overall well-being, it does not specifically address the positional issue that leads to flat spots.
Choice C rationale:
Keeping the baby awake most of the day is not a suitable solution, as it may lead to sleep deprivation and hinder the baby's development. Adequate sleep is essential for a baby's growth and development.
Choice D rationale:
Tummy time is a valuable activity to promote the baby's neck and upper body strength. While it can indirectly contribute to preventing flat spots by encouraging different head positions, it is not as effective as placing the baby on their back to sleep.
Correct Answer is D
Explanation
A. This is not a primary consideration before bathing a newborn. The timing of the last feeding is more relevant to assessing the risk of hypoglycemia rather than determining readiness for a bath.
B. This temperature is slightly below the recommended range for newborns (36.5°C to 37.5°C). Bathing should be delayed until the newborn's temperature is stable.
C. While care of the umbilical cord is important, it does not determine the timing of the first bath. The cord can be kept dry even if the baby is bathed.
D. Ensuring that the newborn has maintained a stable body temperature for at least 2 hours is crucial before giving the first bath. Bathing can cause a drop in body temperature, so it's essential that the newborn's thermoregulation is stable to avoid hypothermia.
