New York State Basic Emergency Medical Technician (EMT-B) Practice Exam

Which procedure should be used to splint a hand injury?

1. Splint the lower arm with the hand in a position of function

2. Keep the hand hanging loosely without support

3. Splint the hand with the fingers extended

4. Use a rigid splint and immobilize the fingers

The correct answer is: Splint the lower arm with the hand in a position of function

The correct response is to splint the lower arm with the hand in a position of function, as this approach maintains optimal hand functionality while preventing further injury. A position of function is essential for preserving the natural alignment of the bones and joints within the hand and wrist. When splinted appropriately, the hand is positioned with the fingers slightly curled and the thumb in a relaxed position, which is vital to ensure that blood flow is not compromised, and that the tendons and ligaments are not unduly stressed during immobilization. This technique reduces the risk of complications such as stiffness or loss of functionality over time, which can occur if the hand is not properly supported. Ensuring the hand is in a functional position also aids in pain relief and psychological comfort for the patient, as it mimics the natural resting position of the hand. Other options do not provide adequate support or may contribute to further injury. For instance, allowing the hand to hang loosely without support can lead to more movement of the affected area, increasing pain and the possibility of additional damage. Similarly, splinting the hand with the fingers extended can place unnecessary tension on the injuries, complicating recovery. Utilizing a rigid splint to immobilize the fingers without addressing the lower arm would neglect overall
