A patient presents to the emergency department with brisk hemorrhage from a laceration on the lower leg. How should the nurse address the hemorrhage?
1. Tape ABD pads over the wound and reinforce them when they become saturated.

Rationale 3: Ice causes additional tissue damage.
Rationale 4: A tourniquet can cause crush injury to tissues and distal ischemia.
