The client has a fractured tibia. After the cast is applied, he is at high risk for compartment syndrome caused by:
A) Inflammation
B) Joint immobility
C) Muscle atrophy
D) Extremity elevation
Ans: A
Feedback:
One of the most important causes of compartment syndrome is bleeding and edema caused by fractures and bone surgery. Compartment syndrome can result from a decrease in compartment size caused by constrictive dressings and casts, increased content volume caused by inflammation, swelling, bleeding, and venous obstruction, or a combination of the two factors. Muscle atrophy decreases volume of contents; casting (rather than immobility caused by the cast) can compress the compartment. Extremity elevation enhances venous return and decreases edema.
