Psoriasis
28
What 6 things do you do when assessing skin?
1- inspect for color, pigmentation
2- palpate for temp, moisture, texture, thickness, edema, turgor, vascularity, bruising
3- note lesions size, shape, configuration, size, location
4- inspect and palpate the hair for texture, distribution, lesions
5- inspect and palpate the nails for shape contour, consistency
6- teach skin self-exam
29
During the inspection and palpation of the nails, the shape contour should be what?
about 160 degrees
