1. Which of the following is the most common cause of impairment of
tissue integrity?
a) Infection
b) Physical trauma
c) Nutritional imbalances
d) Altered circulation
**b) Physical trauma**
Rationale: Physical trauma (e.g., car accidents, sports injuries, cuts, blunt
trauma, etc.) is the most common cause of impairment or a break in tissue
integrity. Other causes can be related to thermal factors (e.g., burns,
frostbites), chemical injury (e.g., adverse reactions to drugs), infection,
nutritional imbalances, fluid imbalances, and altered circulation (e.g.,
pressure injuries).
2. What is the goal of wound hygiene (e.g., cleansing, irrigation, and
debridement)?
a) To reduce the contaminant burden without causing further tissue
damage or introducing more contaminants
b) To stimulate the inflammatory response and promote granulation tissue
formation
c) To remove all necrotic tissue and foreign bodies from the wound bed
d) To create a moist environment that facilitates wound healing
**a) To reduce the contaminant burden without causing further tissue
damage or introducing more contaminants**
Rationale: Wound hygiene, including thorough examination of the wound
and surrounding tissues, promotes uncomplicated healing of traumatic
skin wounds and is required prior to wound closure. Wound healing is
impaired by various factors (e.g., bacterial contamination, foreign bodies,
wound ischemia, host factors). All traumatic wounds are assumed to be
contaminated. The goal of wound hygiene is to reduce the contaminant
burden without causing further tissue damage or introducing more
contaminants.ÂÂ
