Final answer:
Feeling crepitus and discontinuity in a newborn's clavicle suggests a clavicle fracture, common in LGA newborns, and is typically treated with immobilization for natural bone healing.
Step-by-step explanation:
When you feel crepitus and discontinuity on palpation of a newborn's clavicle, this suggests a clavicle fracture. Large for Gestational Age (LGA) newborns are at higher risk for such injuries during birth. The most common treatment is to immobilize the arm and shoulder using a soft bandage or a splint to allow for natural healing of the bone. The healthcare provider will provide instructions on how to care for the newborn and schedule follow-ups to ensure proper healing.
