Question

When checking a newborn's reflexes, the nurse is unable to elicit one reflex response that is often absent in neonates born vaginally in the breech presentation. How should the nurse attempt to elicit this response?

1. Move the thumb along the sole of the foot

2. Stroke the ulnar surface of the hand and fifth finger lightly

3. Touch the skinfold of the mouth and cheek on the same side

4. Hold in the upright position while pressing the feet flat on the crib mattress (Nugent 326)

Answer 1

To elicit the Babinski reflex in a newborn, the nurse should move a stimulus along the plantar surface of the foot. This reflex, crucial for assessing neurological function in infants, would indicate a problem if present in adults.

Step-by-step explanation:

When a nurse is unable to elicit a reflex that is often absent in neonates born vaginally in the breech presentation, the recommended action would be to stroke the plantar surface of the foot to elicit the Babinski reflex. This is performed by moving a stimulus, such as the examiner's thumb, along the sole of the infant's foot. This neurological exam is essential to check for proper functioning of the lower motor neurons (LMN) and the integrity of the spinal cord and brainstem pathways.

Newborn reflexes are crucial for survival, and while many disappear as the baby grows, they serve as indicators of neurological development. The Babinski reflex, in particular, is expected to be present in newborns but would indicate a problem in adults, such as reduced myelination of the spinal tract.
