Final answer:
Pallor of all extremities suggests the need for an escharotomy in a client with full-thickness circumferential burns of the entire trunk of the body.
Step-by-step explanation:
An escharotomy may be necessary when a client has full-thickness circumferential burns of the entire trunk of the body. One finding that suggests the need for an escharotomy is pallor of all extremities. Circumferential burns can cause constriction of blood vessels, leading to decreased blood flow to the affected areas. Pallor of the extremities indicates compromised blood flow, and an escharotomy may be required to relieve the constriction and restore blood circulation.
