Q

Moro Reflex

A

Also called the startle reflex

To elicit this reflex, place the newborn on his or her back. Support the upper body weight of the supine newborn by the arms, using a lifting motion, without lifting the newborn off the surface. Then release the arms suddenly. The newborn will throw the arms outward and flex the knees; the arms then return to the chest. The fingers also spread to form a C. The newborn initially appears startled and then relaxes to a normal resting position.

68
Q

Palmar and Plantae Grasp Reflex

A
  • Elicit the palmar grasp reflex by placing a finger on the newborn’s open palm. The baby’s hand will close around the finger. Attempting to remove the finger causes the grip to tighten. The grasp should be equal bilaterally.
  • The plantar grasp is similar to the palmar grasp. Place a finger just below the newborn’s toes. The toes typically curl over the finger.

Reversing the direction to which the face is turned reverses the position.

71
Q

Rooting Reflex

A

Elicit therooting reflexby stroking the newborn’s cheek. The newborn should turn toward the side that was stroked and should begin to make sucking movements

72
Q

Babinski Reflex

A

TheBabinski reflexshould be present at birth and disappears at approximately 1 year of age. It is elicited by stroking the lateral sole of the newborn’s foot from the heel toward and across the ball of the foot. The toes should fan out. A diminished response indicates a neurologic problem and needs follow-up.

73
Q

Stepping Reflex

A

Assess thestepping reflexby holding the newborn upright and inclined forward with the soles of the feet touching a flat surface. The baby should make a stepping motion or walking, alternating flexion and extension with the soles of the feet.

The spots are caused by a concentration of pigmented cells and usually disappear spontaneously within the first 4 years of life. They should not be confused with bruises caused by trauma.

77
Q

80
Q

Newborn Breasts

A
