1. A patient arrives with a contaminated traumatic laceration. Which action is
most important for reducing the risk of wound infection?
A. Immediate primary closure without cleaning
B. Routine use of topical antibiotics only
C. Thorough irrigation and removal of devitalized tissue
D. Delaying all wound treatment for 24 hours
Answer: Thorough irrigation and removal of devitalized tissue
Rationale: Irrigation and appropriate debridement reduce bacterial
contamination and remove nonviable tissue that can promote infection.
2. Which factor most directly increases the risk of infection in a traumatic
wound?
A. Adequate tissue perfusion
B. Presence of devitalized tissue
,C. Early wound assessment
D. Appropriate wound cleansing
Answer: Presence of devitalized tissue
Rationale: Devitalized tissue provides an environment that supports bacterial
growth and interferes with normal healing.
3. What is the primary purpose of wound irrigation after traumatic injury?
A. To sterilize all tissue
B. To remove surface contaminants and debris
C. To replace surgical debridement
D. To promote immediate scar formation
Answer: To remove surface contaminants and debris
Rationale: Irrigation mechanically reduces contamination by flushing away dirt,
foreign material, and bacteria.
4. A patient has a heavily contaminated wound with visible foreign material.
What should be done in addition to irrigation?
A. Apply a dressing without further treatment
B. Perform appropriate wound exploration and debridement
C. Close the wound immediately
D. Administer antibiotics and avoid examining the wound
Answer: Perform appropriate wound exploration and debridement
Rationale: Foreign material and nonviable tissue should be identified and
removed when appropriate to reduce the risk of infection.
5. Which practice is most important before performing invasive trauma
procedures?
A. Wearing two watches
B. Strict hand hygiene
C. Applying topical antibiotics to the hands
D. Using sterile gloves without hand hygiene
,Answer: Strict hand hygiene
Rationale: Hand hygiene is a fundamental infection-prevention measure that
reduces transmission of microorganisms between healthcare personnel and
patients.
6. Which patient is at increased risk for traumatic wound infection?
A. A patient with good circulation and a clean superficial wound
B. A patient with devitalized tissue and significant contamination
C. A patient receiving timely wound care
D. A patient with a recently cleaned abrasion
Answer: A patient with devitalized tissue and significant contamination
Rationale: Both contamination and tissue devitalization increase the likelihood
of bacterial proliferation and infection.
7. The purpose of surgical debridement is to:
A. Increase bacterial growth
B. Remove viable tissue
C. Remove nonviable tissue and contaminants
D. Eliminate the need for wound assessment
Answer: Remove nonviable tissue and contaminants
Rationale: Debridement removes tissue that cannot heal effectively and may
harbor microorganisms.
8. Which type of traumatic wound generally has a higher risk of infection?
A. Clean superficial incision
B. Heavily contaminated crush injury
C. Minor paper cut
D. Closed injury without skin disruption
Answer: Heavily contaminated crush injury
, Rationale: Crush injuries may involve extensive tissue damage, impaired
perfusion, and contamination, all of which increase infection risk.
9. A trauma patient has a wound contaminated with soil. Which additional
preventive consideration is important?
A. Tetanus immunization status
B. Vision screening
C. Hearing assessment
D. Routine anticoagulation
Answer: Tetanus immunization status
Rationale: Traumatic wounds contaminated with soil may increase concern for
tetanus, making immunization history an important part of management.
10.Which action best supports prevention of healthcare-associated infection
during trauma care?
A. Reusing contaminated equipment
B. Following standard precautions
C. Avoiding hand hygiene during emergencies
D. Delaying disposal of contaminated materials indefinitely
Answer: Following standard precautions
Rationale: Standard precautions reduce exposure to potentially infectious
materials and help prevent transmission of microorganisms.
11.A patient has an open fracture. Why is infection prevention especially
important?
A. Bone and deep tissues may be exposed to contamination
B. Open fractures always heal without treatment
C. Infection cannot occur in bone
D. Wound cleansing is unnecessary
Answer: Bone and deep tissues may be exposed to contamination
