Answer to Question 1

ANS: D
Nylon is a polyamide polymer derived by chemical synthesis from coal, air, and water. It produces minimal tissue reaction. Nylon has high tensile strength, but it degrades by hydrolysis in tissue at a rate of about 15 to 20 per year. It may be used in all tissues where a nonabsorbable suture is acceptable.

Answer to Question 2

ANS: C
The controlled-release needle is secure so that the suture strand will not separate from the needle inadvertently, but it will release rapidly when pulled off intentionally.
