WEEK 3: Skin, hair, nails, lymphatic, PVS Clinical Reasoning & Evaluating Clinical Evidence Flashcards
Skin hair and nails assessment, what are the order?
Inspection: a thorough visual “look” at the part of the body you are examining- notice bilateral differences/symmetry
Good lighting, pen light, expose the body, instruments
Palpation: using your hands and fingers to touch the client (wash hands, warm hands- consider when to use gloves)
Pressure from light to deep
Get your hands on the area of concern: temp, edema, tenderness, texture
Auscultation: listening with your stethoscope
Bell: low pitched sounds
Diaphragm: high pitched sounds
Percussion: tapping with your finger on the joint of a finger of the opposite hand to elicit a sound
What are the 2 types of sweat glands
Eccrine glands – widely distributed, open directly onto skin surface, help control body temperature
Apocrine glands – found in axilla and groin, stimulated by emotional stress
What are the ABCDE for skin assessment
Melanoma Feature Risks
A for asymmetry
B for irregular borders, especially ragged, notched, or blurred
C for variation or change in color, especially blue or black
D for diameter ≥6 mm or different from other moles, especially changing, itching, or bleeding
E for elevation or enlargement or evolution
What is a macule?
flat, small <1cm
e.g. freckles, flat mole, port wine stains, rickettisial rash, rubella, measles
What is Patches?
flat, large >1cm
What is plaque?
raised, elevated, palpatiable, solid , formed by coalesced papules, larger than 1cm
What is nodules?
> 1cm, extends deeper into skin
e.g cysts, lipomas, fibromas
What is Pustule
fluid filled, purluent fluid
e.g. bacterial infection, folliculitis
What is vesicles?
<1cm, clear fluid
e.g. herpes, allergic contact dermatitis, dermatitis herpetiformis
What is Bulla?
fluid filled, >1cm clear fluid
e.g. pemphigus vulgaris, bullous pemphigoid
What is pustule?
small palpable collection of neutrophils or keratin that appears white
What is Furuncle?
inflamed hair follicle, multiple furuncle together form a carbuncle
What is Wheal?
area of localized dermal edema that evanesces (comes and goes) within a period of 1-2 days. this is primary lesion of urticaria
What is Burrow?
small linear or serpiginous pathways in the epidermis created by the scabies mite
What is a Keloid
A raised scar after an injury has healed.
A keloid is caused by an excess protein (collagen) in the skin during healing
The scar rises after an injury or condition has healed, such as a surgical incision or acne. grows more than hypertrophic scar
what is Hypertrophic Scar
a thick raised scar that’s an abnormal response to wound healing. They more commonly occur in taut skin areas following skin trauma, burns or surgical incisions.
What are the different percussion scan
Resonant
Hyperresonant
Tympany
Dull
Flat
Flat sound
soft, high pitch, short, large pleural effusion
high pitched & short, soft
Typically over solid structures such as bone (spine, scapulae, sternum)
Pleural effusion
Dull
medium, medium pitch, medium duration, e.g. lobar pna
when fluid or solid tissue (mass) replaces air containing lung or pleural space
Pneumonia- alveoli filled with fluid, blood cells
Pleural effusion- pleura filled with serous solution
Hemothorax- pleura filled with blood
Empyema- pleura filled with pus
Tumor or fibrous tissue
Resonant
loud, low pitch, long duration,
Hyperresonant
very loud, lower pitch, longer duration, e.g. COPD, PNA
when lungs are hyperinflated
Loud, lower & longer than resonance
More common in children & very thin adults
COPD
ASTHMA (may be resonant to hyperresonant)
Unilateral: air-filled bulla
Air in lung
tympanitic
loud, high pitch, longer duration, large pnx
loud and high pitched- drum like, longer duration
Excessive air such as pneumothorax
Normal over abdomen; abnormal over chest
What is vellus hair type
Vellus hair – short, fine, less pigmentation
What is terminal hair?
Terminal hair – coarser, pigmented (scalp/eyebrows)
Risk factor for melanoma
Mole changing
Male gender
Hx of melanoma
≥ 50 moles or atypical or unusual moles (dysplastic)
Red or light hair
Actinic lentigines, macular brown (frickles) or tan spots (usually on sun exposed areas)
Heavy sun exposure (especially severe childhood sunburns)
Light eye or skin color (especially freckles/burns easily)
Family history of melanoma
Total body skin inspection should include
Color Moisture Temperature Texture Mobility and turgor Lesions Hair Nails
What is a nevi
the medical term for a mole. Nevi are very common. Most people have between 10 and 40. Common nevi are harmless collections of colored cells. They typically appear as small brown, tan, or pink spots.M
