Which wound classification describes a surgical incision made under ideal conditions with no inflammation encountered?
Answer: Class I – Clean
Class I (Clean) wounds are uninfected operative wounds with no break in sterile technique and no entry into the respiratory, alimentary, or genitourinary tracts.
A Class II wound classification (Clean-Contaminated) applies when:
Answer: The respiratory, alimentary, or genitourinary tract is entered under controlled conditions
Class II includes procedures where a hollow organ is entered in a controlled manner without unusual contamination, such as an elective bowel resection.
The primary purpose of wound irrigation during surgery is to:
Answer: Reduce bacterial load and remove debris from the wound
Wound irrigation dilutes and removes bacteria, necrotic tissue, and foreign material, reducing the risk of surgical site infection (SSI).
Which suture characteristic describes sutures that are absorbed by the body over time through hydrolysis or enzymatic degradation?
Answer: Absorbable sutures
Absorbable sutures lose tensile strength and are digested by body enzymes or hydrolysis, eliminating the need for removal.
Polyglactin 910 (Vicryl) is an example of which type of suture?
Answer: Synthetic absorbable braided suture
Vicryl (polyglactin 910) is a synthetic braided absorbable suture that loses most of its tensile strength by 3–4 weeks.
A closed suction drain (e.g., Jackson-Pratt or Blake drain) functions by:
Answer: Creating negative pressure to actively remove fluid from a surgical site
Closed suction drains use negative pressure from a collapsible bulb or reservoir to actively evacuate serous fluid, blood, or lymph from the surgical site.
