Question 1

Which factor most significantly increases a patient's risk of surgical site infection (SSI)?

Accepted Answer

Uncontrolled diabetes mellitus with elevated blood glucose

Answer

Hyperglycemia impairs neutrophil function and tissue perfusion, significantly increasing susceptibility to SSI.

Question 2

The scrub person should handle tissue on the sterile field by:

Accepted Answer

Using the least traumatic technique, handling tissue as gently as possible

Answer

Gentle tissue handling minimizes trauma, preserves viability, and reduces the risk of postoperative complications including infection and dehiscence.

Question 3

When is prophylactic antibiotic administration most effective for SSI prevention?

Accepted Answer

Within 60 minutes before skin incision (or within 120 minutes for vancomycin)

Answer

Administering prophylactic antibiotics within 60 minutes before incision (120 minutes for vancomycin/fluoroquinolones) ensures adequate tissue levels at the time of potential contamination.

Question 4

Primary intention wound healing occurs when:

Accepted Answer

Wound edges are approximated and secured with sutures, staples, or tissue adhesive

Answer

Primary intention (primary closure) involves directly approximating clean wound edges, resulting in minimal scarring and faster healing.
