RNSG 1128 Exam 2 – Introduction to Health Care Concepts
1. Which of the following best describes the concept of tissue integrity?
A) The ability of body tissues to regenerate and repair to maintain normal
physiological processes
B) The process of blood flowing through arteries and capillaries to deliver
nutrients
C) The exchange of oxygen and carbon dioxide in the alveoli
D) The regulation of body temperature through sweating and shivering
Correct Answer: The ability of body tissues to regenerate and repair to maintain
normal physiological processes
•Rationale: Tissue integrity is defined as the ability of body tissues to regenerate
and/or repair to maintain normal physiological processes. It encompasses the
integument being structurally intact and functioning, along with a normal healing
process. It is not primarily about perfusion, gas exchange, or thermoregulation.
2. What is the primary function of the epithelial tissue in relation to tissue
integrity?
A) It provides structural support and binds tissues together
B) It covers and protects body surfaces and lines body cavities
C) It contracts to produce movement
D) It transmits electrical impulses throughout the body
Correct Answer: It covers and protects body surfaces and lines body cavities
•Rationale: Epithelial tissue is the most important tissue related to tissue integrity
because it covers and protects body surfaces and lines body cavities. Connective
,tissue provides structural support, muscle tissue contracts for movement, and
neural tissue transmits impulses.
3. Which of the following is an antecedent for optimal tissue integrity?
A) Prolonged pressure on bony prominences
B) Adequate perfusion and good nutrition
C) Immunologic reaction and trauma
D) Thermal or radiation injury
Correct Answer: Adequate perfusion and good nutrition
•Rationale: Antecedents of tissue integrity include good nutrition, lack of external
trauma, adequate perfusion, and limited pressure on the site. Prolonged pressure,
immunologic reactions, trauma, and thermal injury are categories of impaired skin
integrity, not antecedents of optimal integrity.
4. What is a negative consequence of impaired tissue integrity?
A) Improved wound healing
B) Enhanced body image
C) Pain and infection
D) Increased fluid retention
Correct Answer: Pain and infection
•Rationale: Negative consequences of impaired tissue integrity include pain,
infection, altered body image, and loss of fluid/electrolytes. Impaired tissue
integrity does not lead to improved wound healing, enhanced body image, or
increased fluid retention.
5. Why might infants be at higher risk for impaired tissue integrity?
A) They have increased apocrine gland activity
B) They have thinner, more permeable skin and less subcutaneous fat
C) They have nonfunctional apocrine glands until puberty
D) They have adequate collagen and strong matrix cells
Correct Answer: They have thinner, more permeable skin and less subcutaneous
fat
,•Rationale: Infants have thinner, more permeable skin and less subcutaneous fat,
which predisposes them to fluid loss and less effective temperature regulation.
Adolescents have increased apocrine and sebaceous gland activity causing acne,
and young children have nonfunctional apocrine glands until puberty.
6. What is the primary function of collagen in healthy skin structure?
A) It provides color to the skin
B) It strengthens the skin and provides structural support
C) It produces sweat and sebum
D) It transmits sensory information
Correct Answer: It strengthens the skin and provides structural support
•Rationale: Collagen is a fibrous protein that strengthens the skin and provides
structural support. Adequate collagen is a characteristic of healthy skin structure.
Melanocytes provide color, sweat glands produce sweat, and nerve endings
transmit sensory information.
7. Which interrelated concept directly affects tissue integrity by impacting
oxygen delivery to tissues?
A) Nutrition
B) Perfusion
C) Elimination
D) Sensory perception
Correct Answer: Perfusion
•Rationale: Perfusion is an interrelated concept of tissue integrity because it
directly affects oxygen and nutrient delivery to tissues. When perfusion is
impaired, tissues are at risk for breakdown and impaired healing. Nutrition,
elimination, and sensory perception also affect tissue integrity but through
different mechanisms.
8. Which finding is most consistent with a Stage 1 pressure injury?
A) Full-thickness skin loss with exposed bone
B) Partial-thickness skin loss with a blister
, C) Intact skin with non-blanchable redness
D) Full-thickness skin loss with visible fat
Correct Answer: Intact skin with non-blanchable redness
•Rationale: A Stage 1 pressure injury is characterized by intact skin with non-
blanchable redness of a localized area, usually over a bony prominence. Stage 2
involves partial-thickness skin loss, Stage 3 involves full-thickness skin loss with
visible fat, and Stage 4 involves full-thickness skin loss with exposed bone, tendon,
or muscle.
9. What is the primary purpose of the Braden Scale?
A) To assess cognitive function in older adults
B) To predict the risk for pressure injury development
C) To evaluate wound healing progression
D) To measure body mass index
Correct Answer: To predict the risk for pressure injury development
•Rationale: The Braden Scale is a standardized tool used to assess a patient's risk
for developing pressure injuries. It evaluates six factors: sensory perception,
moisture, activity, mobility, nutrition, and friction/shear. It does not assess
cognitive function, wound healing, or body mass index.
10.Which nutritional deficiency most directly impairs wound healing?
A) Vitamin K deficiency
B) Protein deficiency
C) Sodium deficiency
D) Potassium deficiency
Correct Answer: Protein deficiency
•Rationale: Protein is essential for collagen synthesis, tissue repair, and immune
function. Protein deficiency impairs wound healing and increases the risk of
dehiscence. Vitamin K deficiency affects clotting, and sodium and potassium
deficiencies affect fluid and electrolyte balance but are not directly responsible for
wound healing.
11.What is the primary purpose of the TACO method in wound assessment?
