Answer:
2. "If her hand gets real cool and pale, I can apply the heating pad to it."
Rationale:
The mother needs to understand that compartment syndrome is a complication of fracture and casting and can result in permanent limb damage as a result of pressure-related tissue necrosis. The extremity is elevated to prevent swelling, and the health care provider is notified immediately if any signs of neurovascular impairment develop. Cold fingers could indicate neurovascular impairment and should be reported. A heating pad is not applied to the cast or fingers. Skin edges are checked to monitor for irritation and skin breakdown.
