25
Aging on the Integumentary system:
- Loss of fat, collagen, and elasticity - Dermis become thinner - Decrease pigment - Formation of brown spots - Decreased circulation - Thinning or graying of hair - Less sweat glands
26
How to maintain healthy skin:
- Proper nutrition - Adequate circulation - Regular cleansing - Careful hand washing - Limited exposure to sunlight - Use of sunscreen - Water!
27
During a health history, the nurse asks what:
- skin allergies - allergic reactions to food, meds, and chemicals - previous skin problems - skin cancer - any change in hygiene products

38
Plague | Give example.
Solid mass, circumscribed border. may have flat top > 1cm psoriasis
39
Wheal
- elevated mass with transient borders - aka hive - no fluids - caused by movement of serous fluid into dermis - no fluid free vesicles examples: urticaria (hives), insect bites
40
Pustule
Pus filled vesicle or bulla Examples: acne, impetigo, carbuncles, furuncles
41
Nodule
solid mass deeper than dermis 0.5 - 2.0 cm circumscribed example: lipoma, squamous cell carcinoma

Tumor
solid mass deep than dermis 1-2 cm may not be circumscribed examples: larger lipoma, carcinoma, neurofibromas
43
Cyst
- encapsulated fluid filled or semisolid mass - in subcutaneous tissue or dermis - examples: sebaceous cyst (acne) or epidermoid cysts
44
Wood's Light Examination
Use of a high pressure mercury lamp that produces long wave ultraviolet rays. Used for fungal and bacterial infections.
45
Tzanck Smear
Secretions from a suspected lesion are applied to a glass slide, stained, and examined under microscopy
46
Biopsy
The removal of a sample of tissue by excision. | Biopsy confirmes or rules out malignancy
