Answer to Question 1

4

Rationale: The preferred injection site for vitamin K in the newborn is the lateral aspect of the middle third of the vastus lateralis muscle in the newborn's thigh. This is the preferred injection site because it is free of major blood vessels and nerves and is large enough to absorb the medi-cation.

Answer to Question 2

2

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.
