Question

nurse rodriguez gently strokes the cheek of a 15 - minute - old infant, who immediately turns her head toward the stimulation and makes sucking motions. the nurse performs this test primarily to confirm the presence of which critical newborn survival mechanism? babinski reflex, showing proper foot dexterity moro reflex, indicating a healthy nervous system rooting reflex, critical for feeding grasping reflex, necessary for bonding when a large object suddenly appears in front of a 3 - month - old infant, the baby throws out its arms and legs and arches its back as if startled or losing support. this reflex, which is thought to be an evolutionary remnant of holding onto a mother, is known as the: tonic neck reflex stepping reflex moro (startle) reflex babinski reflex

Explanation:

First Question:

• Analyze each option:
• Babinski reflex: Involves foot movement (toes fan out), not related to cheek stimulation or feeding. Eliminate.
• Moro reflex: Is a startle reflex (arms flail, cry), not triggered by cheek stroking. Eliminate.
• Rooting reflex: Occurs when cheek is stroked, infant turns head and sucks (critical for finding food/feeding). Matches the scenario.
• Grasping reflex: Involves grasping objects, not related to cheek stimulation or feeding. Eliminate.

• Analyze each option:
• Tonic neck reflex: Involves arm/leg positioning with head turn, not a startle response. Eliminate.
• Stepping reflex: Involves leg movements as if walking, not related to sudden objects. Eliminate.
• Moro (startle) reflex: Occurs with sudden stimuli, infant throws arms/legs, arches back (matches the description of being startled and evolutionary for holding mother).
• Babinski reflex: Foot - related, not a startle - like reflex. Eliminate.

Answer:

C. Rooting reflex, critical for feeding
