Answer to Question 1

ANS: B
These are monosodium urate crystals and are seen in gout.

Answer to Question 2

ANS: C
Synovial fluid contains hyaluronic acid, making it very viscous. Adding a small amount of hyaluronidase powder to the fluid will cause it to liquefy. Cell counts and/or cytocentrifuge slides can then be made.
