Answer:
The principle that is not considered by EMT is B. <em>Gently replace protruding bone ends back beneath the skin to prevent further contamination.</em>
<em>Explanation:</em>
A. Check the distal neurovascular function before and after splinting. TRUE. This is important because the patient should not be neurovascularly compromised at the moment of the splinting and after splinting. There are different techniques to measure this, by marking pulse in the injured leg or arm.
B. Gently replace protruding bone ends back beneath the skin to prevent further contamination. FALSE. This is a <em>controversial point</em>. In general, it is recommended not to move the person and the affected area or bones, and NOT TO REPLACE the bone, aline it or push it back to its original place. It is important to immobilize the affected area in the position it was found to relieve the pain and avoid more damage.
C. Splint an isolated extremity injury before moving the patient to the stretcher. TRUE. The injured body area must be splinted in the same position the patient was found. If the patient is comfortable, he/she should not be moved before splitting.
D. Immobilize the site of an extremity injury from the joint above it to the joint below it. TRUE. This is important to prevent any movement. The split must include both the joints, the above one and the below one.
