While assessing a patient's hands, the nurse notes that the patient is unable to fully extend the ring or fifth finger of both hands. This finding is consistent with which of the following?
1. Dupuytren's contracture
2. Bouchard's nodes
3. Heberden's nodes
4. Swan neck deformity
Dupuytren's contracture
Rationale: Difficulty extending or the inability to extend the ring or fifth finger of the hands is a sign of Dupuytren's contracture, an abnormal finding when conducting range of motion of the hands and fingers. Bouchard's nodes are hard, painless nodules over the proximal interphalangeal joints of the fingers. Heberden's nodes are hard, painless nodules over the distal interphalangeal joints of the fingers. A swan neck deformity is when the proximal interphalangeal joint is hyperextended and the distal joint is fixed in flexion.
