Sample Questions

 

Multiple Choice
Identify the choice that best completes the statement or answers the question.

____ 1. What is the function of the stratum corneum?
1)
Provides insulation for temperature regulation
2)
Provides strength and elasticity to the skin
3)
Protects the body against the entry of pathogens
4)
Continually produces new skin cells

ANS: 3
The stratum corneum is the outermost layer of the epidermis and is composed of numerous thicknesses of dead cells. Functioning as a barrier to the environment, it restricts water loss, prevents entry of fluids into the body, and protects the body against the entry of pathogens and chemicals. The subcutaneous layer is composed of adipose and connective tissue that provide insulation, protection, and an energy reserve (adipose). The dermis is composed of irregular fibrous connective tissue that provides strength and elasticity to the skin. The stratum germinativum is the innermost layer of the skin that produces new cells, pushing older cells toward the skin surface.

____ 2. Skin integrity and wound healing are compromised in the client who takes blood pressure medications because antihypertensives:
1)
Can cause cellular toxicity.
2)
Increase the risk of ischemia.
3)
Delay wound healing.
4)
Predispose to hematoma formation.

ANS: 2
Blood pressure medications decrease the amount of pressure required to occlude blood flow to an area, creating a risk for ischemia. Chemotherapeutic agents delay wound healing because of their cellular toxicity. Anticoagulants can lead to extravasation of blood into subcutaneous tissue, predisposing to hematoma formation with minimal pressure or injury.

____ 3. What is the primary difference between acute and chronic wounds? Chronic wounds:
1)
Are full-thickness wounds, but acute wounds are superficial.
2)
Result from pressure, but acute wounds result from surgery.
3)
Are usually infected, whereas acute wounds are contaminated.
4)
Exceed the typical healing time, but acute wounds heal readily.

ANS: 4
The length of time for healing is the determining factor when classifying a wound as acute or chronic. Acute wounds are expected to be of short duration. Wounds that exceed the anticipated length of recovery are classified as chronic wounds.

____ 4. A patient with quadriplegia presents to the outpatient clinic with an ischial wound that extends through the epidermis into the dermis. When documenting the depth of the wound, how would the nurse classify it?
1)
Partial-thickness wound
2)
Penetrating wound
3)
Superficial wound
4)
Full-thickness wound

ANS: 1
Partial-thickness wounds extend through the epidermis into the dermis. Superficial wounds involve only the epidermal layer of skin. Full-thickness wounds extend into the subcutaneous tissue and beyond. Penetrating is a descriptor sometimes added to indicate that the wound includes internal organs.

PTS: 1 DIF: Easy REF: pp. 1226-1227
KEY: Nursing process: Assessment | Client need: PHSI | Cognitive level: Application
