1. The hips of a newborn are examined for developmental dysplasia. Which clinical finding
indicates an incomplete development of the acetabulum?
a. Negative Barlow test
b. Equal knee heights
c. Negative Ortolani sign
d. Thigh and gluteal creases are asymmetric.
ANS: D
Asymmetric thigh and gluteal creases may indicate potential dislocation of the hip. If the hip
is dislocated, the knee on the affected side will be lower. A positive Ortolani sign yields a
clunking sensation and indicates a dislocated femoral head moving into the acetabulum.
During a positive Barlow test, the examiner can feel the femoral head move out of the
acetabulum.

2. Which newborn reflex is elicited by stroking the lateral sole of the infant’s foot from the
heel to the ball of the foot?
a. Babinski
b. Stepping
c. Tonic neck
d. Plantar grasp
ANS: A
The Babinski reflex causes the toes to flare outward and the big toe to dorsiflex. The
stepping reflex occurs when infants are held upright, with their heel touching a solid surface,
and the infant appears to be walking. The tonic neck reflex (also called the fencing reflex)
refers to the posture assumed by newborns when in a supine position. Plantar grasp reflex is
similar to the palmar grasp reflex; when the area below the toes is touched, the infant’s toes
curl over the nurse’s finger.
