Colorado CNA Practice Exam

When a joint is extended beyond its normal motion, it is:

1. Hyperextended

2. Hypoextended

3. Immobilized

4. Stretched

The correct answer is: Hyperextended

When a joint is extended beyond its normal motion, it is considered hyperextended. This is when a joint is extended beyond its usual range of motion but not to the point of dislocation or injury. Option B is incorrect because hypoextended would indicate not enough extension. Option C, immobilized, would indicate the joint is held in place and cannot move. Option D, stretched, would indicate that the joint is elongating or being pulled apart, which is not the case when a joint is hyperextended.
