Answer to Question 1
C
The presence of hyperglycemia in the immediate postoperative period increases the risk for infection in both diabetic and nondiabetic patients. The higher the serum glucose, the greater the potential for infection in both patient groups. Hyperglycemia has been shown to inhibit the body's ability to fight infection. Immediate postoperative glucose control also has been correlated with a reduction in surgical infection.
Answer to Question 2
A

Also, instruct the patient not to cough, sneeze, or breathe deeply during the procedure because these actions increase the risks for needle displacement and damage to other structures.
