Question 1

Primary intention wound healing is characterized by:

Accepted Answer

Approximating wound edges with sutures or staples

Answer

Primary intention healing occurs when wound edges are directly approximated (sutured or stapled), resulting in minimal scarring and faster healing.

Question 2

A Penrose drain operates by which mechanism?

Accepted Answer

Passive gravity and capillary action

Answer

A Penrose drain is a soft rubber tube that uses passive gravity and capillary action to allow fluid to drain from the wound — no suction device is needed.

Question 3

A Jackson-Pratt (JP) drain maintains drainage by:

Accepted Answer

Negative pressure created by compressing the bulb reservoir

Answer

The Jackson-Pratt drain uses a collapsible bulb that creates low-level negative pressure (suction) when compressed and reconnected to the drain tubing.

Question 4

Wound dehiscence is defined as:

Accepted Answer

Separation of the approximated wound edges

Answer

Dehiscence refers to the partial or complete separation of wound edges after closure, most commonly seen within the first postoperative week.

Question 5

Which systemic condition MOST significantly impairs postoperative wound healing?

Accepted Answer

Uncontrolled diabetes mellitus

Answer

Uncontrolled diabetes impairs wound healing through microvascular disease, impaired neutrophil function, and altered collagen synthesis, greatly increasing infection and dehiscence risk.
