Question

a person who will not or cannot move an injured joint is most likely suffering from a--

dislocation.

strain.

deformation.

all of the above

Explanation:

• Dislocation: Occurs when bones in a joint are displaced. This often causes severe pain and immobility of the joint.
• Strain: Involves overstretching or tearing of muscles or tendons. While it causes pain and reduced movement, it's not typically associated with complete inability to move a joint (unless very severe, but less common than dislocation in causing immobility).
• Deformation: Usually refers to a change in shape of a body part. It may or may not directly cause inability to move a joint (e.g., a deformed bone due to a healed - wrong fracture may limit movement, but it's not the most direct cause of immobility compared to dislocation).

Since dislocation is the most direct cause of a joint being immobile (as the normal joint - bone alignment is disrupted), and strain and deformation are less likely to cause complete inability to move the joint in most cases.

Answer:

Dislocation.
