A nurse is taking care of a client with a displaced fracture. The nurse knows a displaced fracture is best described as?
A fracture in which the bone is completely broken into two or more pieces
A fracture in which the bone breaks through the skin
A fracture in which the broken ends of the bone are out of alignment
A fracture in which the bone is partially cracked but still intact
The Correct Answer is C
A. A fracture in which the bone is completely broken into two or more pieces. This describes a complete fracture but does not necessarily imply displacement.
B. A fracture in which the bone breaks through the skin. This describes an open or compound fracture, not specifically a displaced fracture.
C. A fracture in which the broken ends of the bone are out of alignment. This is the correct definition of a displaced fracture. The bone ends are misaligned and require reduction to align properly.
D. A fracture in which the bone is partially cracked but still intact. This describes a partial or incomplete fracture, such as a greenstick fracture, not a displaced fracture.

Correct Answer is C
Explanation
A. It increases formation of purines. Increasing purine formation would exacerbate gout by increasing uric acid levels.
B. It increases metabolism of purines. Allopurinol does not increase the metabolism of purines.
C. It blocks formation of uric acid. Allopurinol works by inhibiting xanthine oxidase, an enzyme involved in the production of uric acid, thereby reducing uric acid levels in the body.
D. It excretes protein. Allopurinol does not promote protein excretion; it specifically targets uric acid metabolism.
