#1. A post-op wound infection with crepitus and foul-smelling discharge suggests infection by: ? Gas gangrene (crepitus) is classic for Clostridium.
Gas gangrene (crepitus) is classic for Clostridium.
#2. Which intervention is MOST effective in reducing SSI risk? ? Hypothermia → vasoconstriction → poor wound perfusion → ↑ SSI.
Hypothermia → vasoconstriction → poor wound perfusion → ↑ SSI.
#3. Which of the following is the MOST common complication following surgical procedures? ? Postoperative pneumonia is the most common complication after surgery, while SSI is the second most common
Postoperative pneumonia is the most common complication after surgery, while SSI is the second most common
#4. A surgical wound with bacterial presence but no signs of systemic inflammation is termed: A) Contamination B) Colonization C) Infection D) Sepsis E) Necrosis ? Colonization refers to bacteria present in a wound without systemic inflammation (usually <10⁵ CFU/mL). Contamination is transient bacterial exposure (<6 hours).
Colonization refers to bacteria present in a wound without systemic inflammation (usually <10⁵ CFU/mL). Contamination is transient bacterial exposure (<6 hours).
#5. A patient with a prosthetic knee develops pain/swelling 8 months post-op. Joint aspirate shows pus. This is: ? Prosthetic infections can occur up to 1 year later = organ/space SSI.
Prosthetic infections can occur up to 1 year later = organ/space SSI.
#6. A 45-year-old diabetic patient undergoes an elective hernia repair. On postoperative day 5, he develops redness, warmth, and pus discharge from the incision site. What is the most likely diagnosis? ? Redness, pus, and warmth within 30 days of surgery fit superficial SSI (involves skin/subcutaneous tissue).
Redness, pus, and warmth within 30 days of surgery fit superficial SSI (involves skin/subcutaneous tissue).
#7. A patient develops fever and purulent drainage from an abdominal incision 3 weeks after a colectomy. Culture grows Staphylococcus aureus. What type of SSI is this? ? Infection involving fascia/muscle (deeper layers) = deep incisional SSI.
Infection involving fascia/muscle (deeper layers) = deep incisional SSI.
#8. Which of the following surgeries is classified as a “clean-contaminated” wound? ? Entering the colonized gallbladder (biliary tract) under controlled conditions = clean-contaminated.
Entering the colonized gallbladder (biliary tract) under controlled conditions = clean-contaminated.
#9. The FIRST step in managing an infected surgical wound with pus is: ? Source control (drainage) is critical before antibiotics.
Source control (drainage) is critical before antibiotics.
