Physical Assessment of the Integumentary System

2 Integument means covering. Integument means covering. The skin and its accessory organs, hair, nails and glands comprise the integumentary system of the body. The skin and its accessory organs, hair, nails and glands comprise the integumentary system of the body. The skin is composed of several different tissue types and is considered an organ.

5 The Three Layers of the Integument Epidermis – the outermost layer of the skin, made of stratified squamous epithelium. Epidermis – the outermost layer of the skin, made of stratified squamous epithelium. Dermis – the inner layer of the skin, made of dense fibrous connective tissue. Dermis – the inner layer of the skin, made of dense fibrous connective tissue. Subcutaneous tissue – thick, fat-containing tissue. Below the skin; the tissues between the dermis and the muscles. Subcutaneous tissue – thick, fat-containing tissue. Below the skin; the tissues between the dermis and the muscles.Human Case Study-Evaluating and Managing Integumentary Conditions.

6 Epidermal Appendages Hair is threads of keratin Hair is threads of keratin Sebaceous glands secrete the oil, sebum Sebaceous glands secrete the oil, sebum Sweat glands Sweat glands –Eccrine glands secrete sweat –Apocrine glands secrete thicker, milky secretion as in anogenital, nipples, and illae areas Nails are hardened keratin Nails are hardened keratin.Human Case Study-Evaluating and Managing Integumentary Conditions.

7 Receptors in the skin The sensory receptors in the dermis are for cutaneous sensations which include: touch, pressure, heat, cold, and pain. The sensory receptors in the dermis are for cutaneous sensations which include: touch, pressure, heat, cold, and pain. The purpose of sensory receptors is to provide the CNS with information about the external environment and its effect on the skin.

17 Hair and scalp Inspection Inspect distribution & quality Inspect distribution & quality Texture Texture Inspect the Scalp: Inspect the Scalp: –Lesions –Excoriations –Lumps –Bruises –Lice.

18 Nails Color, Shape & Contour Color, Shape & Contour Texture Texture Integrity Integrity Thickness Thickness Capillary refill Capillary refill.Human Case Study-Evaluating and Managing Integumentary Conditions.

19 Palpation Temperature Temperature –Assess with dorsum of hand –Warmth reflects circulation –Compare sides Moisture Moisture –Refers to the skin’s hydration level in terms of both wetness & oiliness –Diaphoresis, dehydration Texture Texture –Should feel smooth, soft, & resilient

20 Palpation continued Tenderness Tenderness Thickness Thickness –Callus –Atrophic Edema Edema –Not a “normal finding” –Common in some disorders Cardiovascular Cardiovascular Renal failure Renal failure Cirrhosis Cirrhosis

21 Edema grading –May be pitting –1+ Barely Visible –2+ Indentation < 5mm –3+ Indentation of 5 to 10mm –4+ Indentation of 10mm or >

22 Palpation continued Turgor Turgor –Reflection of skin’s elasticity & hydration –Turgor is decreased (less elasticity) as the skin “tents” and stands by itself Hygiene, odor Hygiene, odor Vascularity or bruising Vascularity or bruising.Human Case Study-Evaluating and Managing Integumentary Conditions.

23 Lesion Types Types of Lesions Types of Lesions –Primary – those developing from previously unaltered skin –Secondary – those which develop over time because of a factor such as scratching or infection

24 If any Lesions present, note the: Color Color Shape and configuration Shape and configuration Size Size Elevation Elevation Excudate Excudate Location and distribution Location and distribution Table 12-3 to 12-11, pages 250-265, Jarvis Table 12-3 to 12-11, pages 250-265, Jarvis

25 Self-Care Behaviors Teach skin self-examination, using the ABCDE rule A—asymmetryB—borderC—colorD—diameter E—elevation and enlargement

26 Developmental Considerations Infants Infants –Lanugo (fine downy hair) from 3 months gestation to a few months after birth –Thin, smooth, highly permeable and elastic skin –Increased sebum through the first few weeks of life –Temperature regulation inefficient.Human Case Study-Evaluating and Managing Integumentary Conditions.

27 Developmental Considerations Aging Adults Aging Adults –Skin loses elasticity and underlying fat reserves –Vascularity diminishes –Decreased response of sweat glands –Lifetime of environmental trauma –Wound healing decreased –Melanocytes decreases melanin production –Loss of self-esteem.
