The nurse is checking the reflexes of a neonate. In eliciting the Moro reflex, the nurse would do which of the following?
1. Stimulate the perioral cavity with a finger.
2. Clap hands, or slap the mattress.
3. Stimulate the ball of the infant's foot with firm pressure.
4. Stimulate the pads of the infant's hands with firm pressure.

Rationale: The Moro reflex is elicited by a loud noise, such as a hand clap or a slap on the mat-tress. The neonate should respond (in sequence) with extension and abduction of the limbs, fol-lowed by flexion and abduction of the limbs and then by flexion and adduction of the limbs. This reflex disappears at 6 months of age. The rooting reflex is elicited by stimulating the perioral area with the finger. The palmar grasp reflex is elicited by stimulating the palm of the hand with firm pressure, and the plantar grasp reflex is elicited by stimulating the ball of the foot with firm pressure.
