subcutaneous tissue
|
|

4 layers: germaine gladly licks c----
1. stratum germanitivum 2. stratum granulosum 3. stratum lucidum 4. stratum corneum |
|
you get a new layer of (epidermal) skin every___?
|
3-4 weeks
|
|
Which layer(s) of the epidermis contains dividing cells?

How would you assess skin, objectively?

2. erythema (redness) - inflamm/infec 3. jaundice (yellowness) - liver funcn (along with yellow sclera) 4. cyanosis (blue) - poor circ/o2 along with blue muc memb |
|
hyperpyrexia vs hyperthermia
|
hyperpyrexia = thermostat set high, body will keep trying to reach temp, sponge baths will not help
hyperthermia = heat from outside sources causes body temp incrse - may be treated with sponge baths |
|
Profuse sweating? excessive dryness?

|
profuse sweating
|
|
When assessing hair, what do you look for?
|
color
texture distribution lesions |
|
How do you inspect nails
|
shape and contour - check for clubbing
Color - capillary refill Consistency cuticle - no inflammation, attached |
|
How do you check for finger clubbing? What does a positive result for finger clubbing indicate?
|
place first phalanges of forefinger together. no space between = clubbing.
clubbing is a result of chronic hypoxia. Usually indicates pulmonary or cardiovascular disease. |
|
what is the difference between primary and secondary skin lesions? |
primary skin lesions - caused by disease/abnormality
secondary skin lesion - caused by primary skin lesion (ie scab from eczema) |
|

|
zosteriform - from herpes zoster
|
