Quiz: General Surgery Wounds — 23 questions

1. Which statement best defines a wound?

A. A coordinated process that restores tissue structure and function after injury

B. A scar that has gained strength after prolonged collagen remodeling

C. A temporary increase in blood flow that supports tissue repair

D. A break in the skin, mucous membrane, or underlying tissue caused by injury

Answer: (D)

Explanation

A wound is a discontinuity in the skin, mucous membrane, or underlying tissue resulting from physical, chemical, or biological injury. The tissue-restoring process describes wound healing rather than the wound itself.

2. What is the primary goal of wound healing after an injury?

A. To remove all connective tissue from the injured region

B. To create a permanent break in the protective tissue barrier

C. To replace the injured area with tissue lacking organized structure

D. To restore tissue continuity, structure, and function

Answer: (D)

Explanation

Wound healing is the body’s coordinated process for restoring tissue continuity, structure, and function. A wound, by contrast, represents disrupted tissue integrity rather than its restoration.

3. A patient has deep tissue damage beneath intact skin after being struck by a blunt object. Which cause and mechanism best describe this injury?

A. Penetrating injury creating an entry through the tissue

B. Burn injury causing tissue damage through thermal exposure

C. Surgical insult producing a controlled operative incision

D. Blunt injury causing deep damage without an obvious skin break

Answer: (D)

Explanation

Blunt injury can damage deeper tissues without producing an obvious break in the skin. Penetrating injury differs because it creates an entry through the tissue.

4. Which feature most clearly distinguishes a tidy wound from an untidy wound?

A. A tidy wound is clean-cut with little devitalized tissue, whereas an untidy wound is irregular and often devitalized

B. A tidy wound contains extensive vascular damage, whereas an untidy wound has well-defined tissue edges

C. A tidy wound is caused by crushing, whereas an untidy wound is produced by a sharp clean instrument

D. A tidy wound is associated with burns, whereas an untidy wound has minimal tissue disruption

Answer: (A)

Explanation

Tidy wounds are generally sharp, clean-cut, and have little or no devitalized tissue, while untidy wounds commonly result from crushing, tearing, avulsion, vascular injury, or burns. The alternatives reverse or misapply these characteristic features.

5. A wound has failed to heal within the expected period and has begun to recur. How should it be classified?

A. Acute, because all wounds eventually undergo a healing response

B. Chronic, because delayed healing and recurrence are characteristic features

C. Superficial, because recurrence usually involves the epidermis alone

D. Tidy, because delayed healing indicates a clean wound margin

Answer: (B)

Explanation

Chronic wounds fail to heal within the expected time and may recur, with the stated duration ranging from more than four weeks to three months. Acute wounds generally heal within the expected time.

6. Which sequence correctly lists the four surgical contamination classes?

A. Open, closed, tidy, untidy

B. Acute, chronic, recurrent, nonhealing

C. Clean, clean-contaminated, contaminated, dirty or infected

D. Superficial, partial-thickness, full-thickness, penetrating

Answer: (C)

Explanation

The four surgical contamination classes are clean, clean-contaminated, contaminated, and dirty or infected. The other sequences describe depth, healing behavior, or different wound distinctions rather than contamination classes.

7. A wound extends through the entire epidermis and dermis into subcutaneous fat. Which depth classification applies?

A. Partial-thickness wound

B. Closed wound

C. Superficial wound

D. Full-thickness wound

Answer: (D)

Explanation

A full-thickness wound involves the entire epidermis and dermis and may extend into fat or deeper structures. A partial-thickness wound involves the epidermis and only part of the dermis.

8. Which statement best describes the relationship among the phases of wound healing?

A. The proliferative phase begins only after maturation and remodeling have ended

B. The maturation phase replaces inflammation before any new tissue formation occurs

C. The inflammatory, proliferative, and maturation phases occur as completely separate stages

D. The inflammatory, proliferative, and maturation phases overlap during repair

Answer: (D)

Explanation

Wound healing progresses through inflammatory, proliferative, and maturation and remodeling phases that overlap. They are not completely separate stages with one phase waiting for the entire previous phase to end.

9. During the early inflammatory response, which sequence of cellular activity is expected?

A. Erythrocytes act early, followed by keratinocytes that later release growth factors

B. Macrophages act early, followed by neutrophils that later remove bacteria and debris

C. Neutrophils act early, followed by macrophages that later predominate and release signaling factors

D. Fibroblasts act early, followed by epithelial cells that later control bleeding

Answer: (C)

Explanation

Neutrophils initially remove bacteria and debris, while macrophages become predominant later and release cytokines and growth factors. Fibroblasts and epithelial cells have important roles in later repair rather than this early inflammatory sequence.

10. Which combination of processes characterizes the proliferative phase of wound healing?

A. Angiogenesis, fibroplasia, granulation tissue formation, epithelialization, and contraction

B. Vasoconstriction, reduced blood flow, tissue cooling, and clot breakdown

C. Collagen reorganization, scar strengthening, and long-term remodeling

D. Hemostasis, neutrophil recruitment, macrophage activation, and cytokine release

Answer: (A)

Explanation

The proliferative phase replaces lost tissue through angiogenesis, fibroplasia, granulation tissue formation, epithelialization, and wound contraction. Hemostasis and inflammatory-cell recruitment belong mainly to the inflammatory phase, while collagen reorganization characterizes maturation and remodeling.

11. Why can a mature scar remain weaker than uninjured tissue even after remodeling has continued for a year or longer?

A. Epithelial cells replace collagen, producing tissue that lacks any structural organization

B. Collagen is removed completely, preventing the scar from gaining any mechanical strength

C. Collagen is reorganized and strength increases, but full original tissue strength is not necessarily regained

D. Remodeling ends within several days, so the scar cannot undergo prolonged strengthening

Answer: (C)

Explanation

Maturation and remodeling may last a year or longer as collagen is reorganized and the scar gradually gains strength. However, the repaired tissue does not necessarily regain the full strength of uninjured tissue.

12. Which wound-management approach best represents healing by primary intention?

A. Delaying closure while observing a wound for several days after cleaning

B. Allowing a tissue-deficient wound to heal through granulation and contraction

C. Closing a clean wound by approximating its edges with sutures, staples, or adhesive

D. Leaving a contaminated wound open until bacterial contamination has decreased

Answer: (C)

Explanation

Primary intention closes a clean wound with minimal tissue damage by bringing its edges together, which limits tissue loss and scarring. Leaving a wound open for granulation describes secondary intention, while delayed closure describes tertiary intention.

13. A large traumatic wound has substantial tissue loss, and its edges cannot be brought together. Which healing process is most likely to occur?

A. Tertiary intention, involving closure after a short period of observation

B. Direct regeneration, involving rapid restoration without an open wound

C. Primary intention, involving immediate edge-to-edge closure with sutures

D. Secondary intention, involving granulation, epithelialization, and contraction

Answer: (D)

Explanation

Secondary intention is used when tissue loss or extensive trauma prevents approximation of the wound edges, so healing proceeds through granulation, epithelialization, and contraction. Primary intention requires direct closure, whereas tertiary intention involves delayed closure after initial wound management.

14. A heavily contaminated wound is left open for cleaning and observation and then closed after bacterial contamination decreases. What type of healing does this describe?

A. Secondary intention

B. Immediate epithelial repair

C. Tertiary intention

D. Primary intention

Answer: (C)

Explanation

Tertiary intention involves initially leaving a heavily contaminated wound open and closing it later, often after three to five days. Primary intention closes a clean wound promptly, while secondary intention allows an open wound to heal without planned delayed closure.

15. Which local condition most directly impairs wound healing by reducing oxygen and nutrient delivery to the tissue?

A. Controlled systemic inflammation

B. Adequate tissue perfusion

C. Tissue ischemia

D. Balanced nutritional intake

Answer: (C)

Explanation

Tissue ischemia is a local factor that limits oxygen and nutrient delivery needed for repair. Adequate perfusion supports healing, while nutrition and systemic inflammation represent broader patient-related considerations.

16. Which condition is classified as a systemic factor that can impair wound healing?

A. Retained foreign body

B. Diabetes mellitus

C. Poor surgical technique

D. Wound-site hematoma

Answer: (B)

Explanation

Diabetes mellitus is a systemic factor because it reflects the patient’s general condition and can interfere with repair. Hematoma, surgical technique, and foreign bodies are local factors arising at or near the wound.

17. What does dehiscence mean in the context of wound healing?

A. Formation of a tract connecting the wound to an epithelial surface

B. Separation or breakdown of a previously closed wound

C. Protrusion of abdominal contents through a disrupted wound

D. Extension of a scar beyond the original wound margins

Answer: (B)

Explanation

Dehiscence is the separation or breakdown of a wound that had previously been closed. Protrusion of abdominal contents is evisceration, while extension beyond the wound margins describes a keloid.

18. A patient’s abdominal contents protrude through a disrupted postoperative wound. What complication is present, and what is the appropriate response?

A. Keloid formation requiring treatment of excess scar tissue

B. Herniation requiring delayed elective assessment

C. Evisceration requiring urgent surgical care

D. Dehiscence requiring routine scar observation

Answer: (C)

Explanation

Evisceration is the protrusion of abdominal contents through a disrupted abdominal wound and is a surgical emergency. Dehiscence describes wound separation without necessarily exposing abdominal contents, while a keloid is an abnormal scar extending beyond the original wound.

19. How does a hypertrophic scar differ from a keloid?

A. A hypertrophic scar stays within the original wound boundaries, whereas a keloid extends beyond them

B. A hypertrophic scar results from infection, whereas a keloid results from tissue ischemia

C. A hypertrophic scar forms a draining tract, whereas a keloid produces wound hemorrhage

D. A hypertrophic scar opens a closed wound, whereas a keloid protrudes abdominal contents

Answer: (A)

Explanation

A hypertrophic scar remains confined to the original wound boundaries, while a keloid grows beyond those margins. Wound separation and abdominal-content protrusion are different complications, and infection or ischemia do not define this scar distinction.

20. Which sequence best represents the general progression of wound management?

A. Reconstruct the defect, assess the patient, document the wound, and begin cleaning after closure

B. Irrigate and debride, discharge the patient, classify the wound, and consider closure later

C. Assess and stabilize, examine and document, clean and irrigate, debride when indicated, close or reconstruct, and follow up

D. Examine and document, close the wound, assess circulation, irrigate afterward, and follow up

Answer: (C)

Explanation

Wound management progresses from patient assessment and stabilization through wound examination, cleaning, indicated debridement, closure or reconstruction, and follow-up. Closing before assessing and preparing the wound reverses important clinical priorities.

21. A patient has a contaminated wound containing visibly dead tissue. Which intervention specifically removes the devitalized tissue?

A. Primary closure brings wound edges together immediately

B. Flap coverage replaces tissue lost from the wound

C. Irrigation flushes visible contamination from the wound

D. Debridement removes clearly devitalized tissue from the wound

Answer: (D)

Explanation

Debridement is directed at removing clearly devitalized tissue, while irrigation is used to remove visible contamination. Irrigation therefore does not perform the same function as debridement.

22. Which set of components best fulfills the recommended structure of a 15-mark wound answer?

A. Patient history, physical examination, laboratory results, imaging findings, treatment consent, and discharge advice

B. Healing phases, wound photographs, instrument lists, anesthesia options, operating-room setup, and billing details

C. Mechanism, irrigation technique, suture selection, dressing choice, antibiotic regimen, and follow-up schedule

D. Definition, causes, classification, healing phases and types, factors, complications, and management principles

Answer: (D)

Explanation

A complete 15-mark wound answer should cover the definition, causes, classification, healing phases and types, relevant factors, complications, and management principles. A clinical procedure list does not provide the full examination structure expected for the answer.

23. Which diagram set best supports a structured examination answer on wounds?

A. A bacterial classification tree, a tissue microscopy plate, a fracture diagram, and a rehabilitation schedule

B. A patient-positioning diagram, a vital-sign chart, a medication table, and a discharge checklist

C. A wound-depth sketch, a suture-knot sequence, an anesthesia map, and a postoperative dressing chart

D. A three-phase healing timeline, a primary-versus-secondary intention comparison, and a wound-management flowchart

Answer: (D)

Explanation

The recommended diagrams cover biological healing phases, the distinction between primary and secondary intention, and the clinical management sequence. A healing timeline explains biology, whereas a management flowchart organizes clinical actions.
