Which phase of wound healing involves fibroblast activity and collagen deposition?

A. Inflammatory

B. Proliferative

C. Maturation

D. Remodeling

Answer: B

Rationale: The proliferative phase includes fibroblast proliferation and collagen formation, helping fill the wound. The slides list inflammatory, proliferative, maturation as the phases of healing.

Full‑thickness wounds require which process to heal?

A. Re‑epithelialization

B. Granulation tissue formation

C. Immediate closure

D. Minimal contraction


Answer: B

Rationale: Full‑thickness wounds “must be filled with granulation tissue to heal.”

Chemical burns are caused by:

A. Electricity

B. Strong acids/alkalis

C. Radiation

D. Flame

Answer: B  

Rationale: Chemical burns result from corrosive substances.

 A superficial burn shows:

A. Mild erythema with blanching

B. Charred tissue

C. Bone exposure

D. No pain

Answer: A  

Rationale: Slides: mild erythema, blanches, painful.

Entire arm equals:

A. 9%

B. 18%

C. 27%

D. 36%

Answer: B  

Rationale: Each arm = 18%.

200

Healing by second intention is characterized by:

A. Edges approximated with sutures

B. Delayed closure

C. Gradual filling of dead space with connective tissue 

D. Minimal scarring


Answer: C

Rationale: Second intention healing requires filling of dead space with connective tissue. The slides state: “Second intention—requires gradual filling in of dead space with connective tissue.”


200

Re‑epithelialization stops when:

A. Cells reach the wound edge

B. Cells meet from opposite sides

C. Granulation forms

D. Scab falls off

Answer: B  

Rationale: Slides: migration halts when epidermal cells meet.


200

Electrical burns are dangerous because they:

A. Only affect skin

B. Cause deep internal injury

C. Are always superficial

D. Heal rapidly

Answer: B  

Rationale: Electrical burns often damage deep tissues.


200

Deep superficial burns show:

A. No pain

B. Large blisters + severe erythema

C. Black eschar

D. Bone exposure

Answer: B  

Rationale: Slides: large blisters, severe erythema.


200

Anterior trunk equals:

A. 9%

B. 18%

C. 27%

D. 36%

Answer: B  

Rationale: Diagram shows 18%.

300

First‑intention healing requires:

A. Wound edges left open

B. Wound edges brought together in correct anatomical position  

C. Granulation tissue formation

D. High infection risk

Answer: B

Rationale: First intention occurs when edges are approximated properly.


300

 Contraction during healing is most associated with:

A. Partial‑thickness wounds

B. Full‑thickness wounds

C. First‑intention healing

D. Chemical burns

Answer: B  

Rationale: Full‑thickness wounds undergo contraction as part of healing.


300

Smoke‑related injuries affect the:

A. Respiratory system

B. Renal system

C. Musculoskeletal system

D. Endocrine system

Answer: A  

Rationale: Slides list smoke‑related injuries under inhalation injuries.

300

Full‑thickness burns show:

A. Moist surface

B. Dry, leathery surface with little pain

C. Redness only

D. Rapid healing

Answer: B  

Rationale: Slides: dry surface, little/no pain.


300

Perineum equals:

A. 1%

B. 5%

C. 9%

D. 18%

Answer: A  

Rationale: Rule of nines: perineum = 1%.

400

Third‑intention healing is associated with:

A. Rapid epithelialization

B. Minimal scarring

C. Delayed closure and high infection risk 

D. No granulation tissue

Answer: C

Rationale: Slides describe third intention as “delayed closure; high risk for infection with resulting scar.”

400

Partial‑thickness wounds involve:

A. Epidermis only

B. Epidermis + upper dermis

C. Entire dermis

D. Subcutaneous tissue

Answer: B  

Rationale: Slides: damage to epidermis and upper dermis.

400

Radiation burns commonly occur from:

A. Sun exposure

B. Steam

C. Flame

D. Electricity

Answer: A  

Rationale: UV exposure is a common radiation burn source.


400

Deep full‑thickness burns involve:

A. Epidermis only

B. Dermis only

C. Muscle and bone

D. Minimal tissue loss

Answer: C   Rationale: Slides: involves muscle and bone.

400

Entire left leg equals:

A. 9%

B. 14%

C. 18%

D. 27%

 Answer: C  

Rationale: Each leg = 18%.

500

Which phase involves vasodilation and leukocyte migration?

A. Inflammatory

B. Proliferative

C. Maturation

D. Remodeling

Answer: A   Rationale: The inflammatory phase begins immediately with vasodilation and leukocyte activity.



500

Partial‑thickness wounds heal primarily through:

A. Granulation

B. Re‑epithelialization

C. Contraction

D. Scar formation

Answer: A  

Rationale: Slides: partial‑thickness wounds heal by re‑epithelialization within 5–7 days.


500

 Thermal burns include:

A. Chemicals

B. Flame and heat

C. Radiation

D. Electricity

Answer: B   Rationale: Thermal burns are heat‑related.

500

 Hard, inelastic eschar is seen in:

A. Superficial burns

B. Partial‑thickness burns

C. Full‑thickness burns

D. Deep full‑thickness burns

Answer: D  

Rationale: Slides: deep full‑thickness burns have hard, inelastic eschar.
