Free plastic surgery MCQ exam model for clinical students

Explanation:

• Release contractures → Correct because Z-plasty lengthens scar tissue.

• Close large wounds → Incorrect because grafts or flaps are used.

• Increase blood supply → Incorrect because it mainly reorients scar.

• Treat infections → Incorrect because it is not for infection.

• Improve wound healing → Incorrect because it is a reconstructive technique.

Explanation:

• Is transferred without its own blood supply → Correct because grafts rely on recipient bed for vascularization.

• Has its own blood supply → Incorrect because this defines a flap.

• Contains muscle → Incorrect because this describes myocutaneous flaps.

• Is used only for cosmetic surgery → Incorrect because grafts are widely used in reconstruction.

• Cannot survive on granulation tissue → Incorrect because grafts survive well on granulation tissue.

Explanation:

• Trauma and burns → Correct because tissue loss commonly requires reconstruction.

• Cosmetic enhancement → Incorrect because it is elective aesthetic surgery.

• Congenital anomalies → Incorrect because they are common but less than trauma.

• Aging changes → Incorrect because this is aesthetic surgery.

• Obesity → Incorrect because it is not an indication.

Explanation:

• Graft failure → Correct because inadequate vascularization or movement causes loss.

• Infection → Incorrect because it is less common than failure.

• Hematoma → Incorrect because it is a contributing factor, not most common outcome.

• Hypertrophic scar → Incorrect because it is a late complication.

• Contracture → Incorrect because it develops later.

Explanation:

• Thermal burns → Correct because flames and hot liquids commonly affect face.

• Chemical burns → Incorrect because they are less common.

• Electrical burns → Incorrect because they cause deep tissue injury but are less frequent.

• Radiation burns → Incorrect because they are rare.

• Friction burns → Incorrect because they are uncommon.

Explanation:

• Form follows function → Correct because restoring function takes priority over appearance.

• Cosmetic outcome only → Incorrect because function is primary.

• Speed of surgery → Incorrect because careful planning is needed.

• Avoiding scars → Incorrect because scars are inevitable.

• Minimal hospital stay → Incorrect because outcome is more important.

Explanation:

• Improve appearance → Correct because cosmetic surgery enhances aesthetic look.

• Save life → Incorrect because it is reconstructive/emergency surgery goal.

• Restore function → Incorrect because it is reconstructive surgery goal.

• Treat malignancy → Incorrect because this is oncologic surgery.

• Prevent infection → Incorrect because it is general surgical care.

Explanation:

• Split-thickness skin graft → Correct because it has high take rate and large coverage.

• Full-thickness skin graft → Incorrect because it is used for smaller defects.

• Composite graft → Incorrect because it is used for small areas.

• Free flap → Incorrect because it is a flap, not graft.

• Pedicled flap → Incorrect because it retains blood supply.

Explanation:

• Reconstruction and aesthetic correction of tissues → Correct because plastic surgery focuses on restoring form and function.

• Removal of tumors only → Incorrect because this is surgical oncology.

• Management of fractures → Incorrect because this is orthopedics.

• Treatment of infections → Incorrect because this is general surgery/medicine.

• Internal organ surgery → Incorrect because this is general surgery.

Explanation:

• Cleft lip and palate → Correct because it requires reconstructive surgery.

• Polydactyly → Incorrect because it is treated by orthopedics or general surgery.

• Club foot → Incorrect because it is orthopedic.

• Hypospadias → Incorrect because it is urologic surgery.

• Neural tube defects → Incorrect because they are neurosurgical.
