Integumentary SystemDifficulty 2/5

A sacral pressure injury shows visible subcutaneous fat without exposed bone, tendon or muscle. How is it staged?

  1. AStage 2, because the wound extends below the epidermis
  2. BStage 3, because full-thickness loss exposes subcutaneous fat
  3. CStage 4, because the wound base is deep and irregular
  4. DUnstageable, because the depth cannot be determined visually
Show answer and rationale

Correct: B. Stage 3 is full-thickness skin loss in which fat is visible but bone, tendon and muscle are not. Stage 4 exposes those deeper structures, and a wound is unstageable only when slough or eschar obscures the base.

  • A — Stage 2 is partial thickness with exposed dermis and no visible fat.
  • C — Stage 4 requires exposed bone, tendon or muscle.
  • D — The base is visible, so the injury can be staged.
Integumentary SystemDifficulty 3/5

Using the rule of nines for an adult, what percentage of total body surface area is burned when the entire anterior trunk and one entire arm are involved?

  1. A22.5 percent, counting the anterior trunk as 18 and half an arm
  2. B18 percent, counting the trunk as 9 and the arm as 9
  3. C27 percent, counting the anterior trunk as 18 and the arm as 9
  4. D36 percent, counting the whole trunk as 27 and the arm as 9
Show answer and rationale

Correct: C. In the adult rule of nines the anterior trunk is 18 percent and an entire upper limb is 9 percent, giving 27 percent.

  • B — The anterior trunk is 18 percent, not 9.
  • D — The whole trunk anterior and posterior is 36 percent, not 27.
  • A — An entire arm is 9 percent, not 4.5.
