Answer to Question 1

ANS: D
The PT, PTT, and TT are all normal in a patient with factor XIII deficiency. Factor XIII deficiency is evaluated by placing the clot in 5M urea; the uncross-linked clot is weak and dissolves within 2 hours in this solution.

Answer to Question 2

ANS: D
Patients with a deficiency of factor XIII have evidence of poor wound healing and anatomic bleeds.
