Chronic wound - ansA wound that has failed to proceed orderly through the healing process.
>28 days.
Acute wound - ansA wound that progresses through the phases of wound healing in a rapid,
uncomplicated manner. Surgical or traumatic wound.
Recalcitrant wound - ansA wound that fails to respond to interventions within 2-4 weeks.
What is a standard of care? - ansMeasures of care established by a professional organization
that are generally accepted by the profession.
What is non-adherence? - ansWhen a patient does not comply with or adhere to interventions
that the healthcare provider deems necessary.
What is informed consent? - ansA process of communication between the patient and the
healthcare provider that often leads to agreement or permission for care, treatment, or
services.
What documentation must be present prior to discharging a patient for continued non-
adherence? - ansEvery instance of non-adherence including your evaluation of reasons for
non-adherence Every instance of patient education and counseling, including diagnosis,
recommended treatment plan, risks and benefits of the plan, prognosis if the plan is not
followed, alternate options, and the patient's response.
What is the Health Insurance Portability and Accountability Act (HIPAA)? - ansA set of
national standards for the protection of a patient's individually identifiable health information
in any form or media, whether electronic, paper, or oral.
What are some recommended interventions when dealing with a non-adherent patient? -
ansSet up mutually compatible goals. Negotiate a treatment plan with the patient. Discuss any
problems the patient is having with the plan. Make complex plans easier to understand and
follow.
Describe the structure of the dermis. - ansThick, dense, fibroelastic, connective tissue that is
highly vascularized.
What is the function of the macrophage? - ansIngest dead tissue and cells, repair injured
tissues and act as a defense mechanism.

Latest Exam Study Guide 2025/2026.
What is the function of the neutrophil? - ansAttack and ingest microorganisms through
phagocytic activity.
What effect does a higher TEWL (transepidermal water loss) in dark skin have? -
ansCompromises the epidermal barrier function making the skin more susceptible to irritants
and possibly drier.
What is the function of desmosomes? - ansBind keratinocytes together and provide strength
to each layer of the skin as the keratinocytes move to the surface.
How is thermoregulation accomplished by the skin? - ansThrough vasodilation (expanding of
blood vessels) and vasoconstriction (narrowing of blood vessels) to dissipate and retain heat
and through the release of sweat.
What are the most common types of white blood cells? - ansLymphocytes and neutrophils
What is the function of the red blood cell? - ansTo attract and move oxygen from the lungs to
the body's cells through hemoglobin.
Describe the structure of the epidermis. - ansConsists of 5 layers of mostly dead cells, is
avascular, and averages 0.1 mm in thickness.

clotting during injury.
What is the function of the fibroblast? - ansDevelop connective tissue and produce collagen
and elastin.
How can you distinguish ligaments from tendons? - ansLigaments are broader, flatter, and
more loosely woven than tendons and the striations feel like tape with embedded threads.
What is the function of Langerhans cells? - ansAre the first line of defense against
environmental antigens by capturing, uptaking, and processing antigens that stimulate an
immune response.
What is the function of the epidermis? - ansProvide a barrier against toxic substances and
microorganisms, prevent water loss, and repel water.
What can disrupt the acid mantle of the skin? - ansOver washing of the skin, frequent use of
alkaline soaps, exposure to incontinence and perspiration, and some skin conditions.
What structures are found in the reticular layer of the dermis? - ansNerves, sweat glands,
sebaceous glands, and hair follicles.
Where is the basement membrane located and what is its function? - ansLocated between the
epidermis and dermis Provide structural support to the skin and facilitate the exchange of
fluid and cells between the skin layers
Describe the appearance of subcutaneous tissue. - ansPale yellow, waxy, globular, oily
substance that glistens
What are the functions of the dermis? - ansNourishment, protection, sensation, and
thermoregulation.
What causes dark skin to be thicker compared to light skin? - ansThe presence of more
compact collagen bundles in higher amounts and a longer BMZ.
What is the difference between constitutive and facultative skin color? - ansThe amount of
melanin in the skin before exposure to UV radiation and hormones (constitutive) vs the
amount after exposure to UV radiation and hormones (facultative)
What substance does the keratinocyte produce and what is the function of that substance? -
ansKeratin, a fibrous protein that makes the epidermis tough.
What is the largest component of the dermis and what is its function? - ansExtracellular
matrix Provides structural support, regulates cellular functions, lubricates cells, and provides
a transport system for nutrients and waste products.
