While assessing a patient's hands, the nurse notes that the patient is unable to fully extend the ring or fifth finger. The nurse would suspect which condition?
1. Dupuytren's contracture
2. Bouchard's nodes
3. Swan neck deformity
4. Heberden's nodes
1
Rationale 1: Difficulty extending or the inability to extend the ring or fifth finger is a sign of Dupuytren's contracture, a thickening of the connective tissue in the palm.
Rationale 2: Bouchard's nodes are hard, painless nodules over the proximal interphalangeal joints of the fingers.
Rationale 3: In a swan neck deformity, the proximal interphalangeal joint is hyperextended and the distal joint is fixed in flexion.
Rationale 4: Heberden's nodes are hard, painless nodules over the distal interphalangeal joints of the fingers.
