Which finding on a newborn assessment should the nurse recognize as suggestive of a clavicle fracture?
a. Negative scarf sign
b. Asymmetric Moro reflex
c. Swelling of fingers on affected side
d. Paralysis of affected extremity and muscles
ANS: B
A newborn with a broken clavicle may have no symptoms. The Moro reflex, which results in sudden extension and abduction of the extremities followed by flexion and adduction of the extremities, will most likely be asymmetric. The scarf sign that is used to determine gestational age should not be performed if a broken clavicle is suspected. Swelling of fingers on affected side and paralysis of affected extremity and muscles are not indicative of a fractured clavicle.
