Skin Integrity and Wound Care Questions Questions
Question 1 of 5
The skin has __ layers, in addition to the subcutaneous tissue layer
Correct Answer: B
Rationale: Two,' because the skin comprises two primary layers the epidermis and dermis excluding the subcutaneous tissue layer, which is beneath the skin proper. The epidermis, the outermost layer, acts as a waterproof barrier and protects against pathogens, while the dermis, below it, houses blood vessels, nerves, and glands, providing strength and elasticity. The subcutaneous layer, or hypodermis, is a separate entity of fat and connective tissue, not counted as a skin layer but as underlying support. 'One' is incorrect, as it ignores the dermis. 'Three' might confuse the subcutaneous layer as a skin layer, which it isn't in standard terminology. 'Four' exceeds the anatomical structure entirely. This distinction is vital in nursing for assessing skin integrity and wounds, as each layer's condition affects healing and care strategies, making 'Two' the accurate choice based on established skin anatomy.
Question 2 of 5
Who of the following is most at risk for a pressure ulcer?
Correct Answer: C
Rationale: Joe Swanson, because he is a paraplegic,' as immobility is the primary risk factor for pressure ulcers. Paraplegia limits movement, causing prolonged pressure on skin over bony prominences (e.g., sacrum), reducing blood flow and leading to tissue breakdown. 'Obesity' increases pressure but allows repositioning unless bedridden. 'Minor brain impairment' may affect awareness, not mobility directly. 'Infant' risks skin fragility, but frequent care mitigates pressure. In nursing, assessing mobility is key Joe's paralysis heightens vulnerability, requiring interventions like turning schedules. C's direct link to sustained pressure distinguishes it as the highest risk per pressure ulcer etiology.
Question 3 of 5
In the process of developing evidence-based practice, after reviewing current research studies, the next step is to:
Correct Answer: A
Rationale: Evidence-based practice (EBP) follows a systematic process: ask, acquire, appraise, apply, assess. After reviewing research (appraise), validating findings in practice is next testing applicability (e.g., a new dressing technique) in real settings. Using data for safety or evaluating outcomes follows application. Searching for evidence is prior. Validation ensures relevance before broader use, aligning with EBP models like Johns Hopkins, making it the correct next step for LPNs integrating research into care.
Question 4 of 5
In setting up her nurses' training, Florence Nightingale carried out her belief that:
Correct Answer: C
Rationale: Nightingale's training at St. Thomas' Hospital emphasized nursing as a skilled profession taught by nurses (Choice C), per her'Notes on Nursing.' Fresh air and nutrition (Choices B, D) were key beliefs, but her legacy was formalizing nurse-led education, elevating standards beyond lay care. This focus professionalized nursing, distinguishing it from medicine, and remains foundational, making it the correct answer reflecting her training philosophy.
Question 5 of 5
A nurse is planning illness prevention activities for patients. The best activity would be:
Correct Answer: B
Rationale: Prevention focuses on avoiding illness onset. Vision screenings detect issues early (e.g., glaucoma), aligning with primary prevention per CDC guidelines. Wound dressing is treatment, not prevention. Referrals and prenatal care are valuable but secondary or specific. Screenings proactively reduce disease burden across populations, a key nursing role, making it the correct and most effective prevention activity.
