Quiz 1/Exam 1 Flashcards
what happens to the subcutaneous layer as we age
As we age we lose the subcut layer, vascular supply is less and there is less nerve endings (skin thins – bc of less nerve endings and elderly person may not feel a wound)
Less protection from cold bc of subcut layer dim as we age
what % of our body is skin
15-20
functions of skin
Protection from injury or invasion
Insulation
Maintenance of homeostasis (sweating)
Assist in metabolism (Vit D production, aids in waste removal of urea and other waste products)
Attachment of muscles (ex. erector pili and frontalis)
Cutaneous sensation
a flat, circumscribed area that is a change in the color of skin, less than 1 cm in diameter

men
melanoma travels where first
lymph and blood
distinguishing from malignant to benign lesions (what are char. of malignant)

risk factors melanoma for men (# of moles)
17 or more moles increases risk for men they have 4.6 x risk for melanoma, 50% of melanoma dev in existing moles
risk factors melanoma for women (# of moles)
12 or more moles , risk is 5.2 x greater
overall risk factors for skin Ca
History ****** Age >50 Regular dermatologist absent M-mole changing M-male gender

elevation or evolution
acne is a
pustule
a wart is a
papule
elevated, irregular-shaped area of cutaneous edema; solid, variable diameter

alcohol wipes or gels/lotions
A chronic, relapsing, proliferative skin disorder with an unknown cause (possibly genetic and/or immunological), flare ups asst. with winter and no sunlight
psoriasis (immune disorder= genetic)
psoriasis is aggravated by stress or change in homeostasis
Assymetrical pxful joint with noticeable skin lesion = (often the DIP of fingers, toes, and SI jts)

3 triage categories of pt condition
minimal
serious - (broken into urgent, immediate and delayed)
expectant
typically, if motion causes the px you can expect the issue to be related to
MSK
which type of triage is “requiring additional treatment before other needs or categories of patients attended to”
serious
medical trumps PT services
which type of triage is “can attend to other needs as well as treat primary condition (can attend to them later – maybe see PCP within a month or so)”
minimal
which type of triage is, “efforts are futile to tx”
expectant

physicians
what are some key competencies she mentioned for a direct access PT to have
Know when to refer (diff dx) know red flags, know how to rule in or rule out know drug interactions ability to read imaging prevention care
if a pt has hx of Ca and px in spine that is difficult to determine a cause…you
refer out
px in upper right quadrant is
gallbladder
px in LOWER right quadrant is
appendix
what is sensitivity
if it has high sensitivity it means it is ruling out the condition (if the sensitive test was neg you rule out)
what is specificity
if it has high specificity it means you are ruling in the condition (if specific test is pos you rule in)
bone scans are highly sensitive, what does this mean
if the test is neg, it rules out the condition
if something has very low sensitivity it means
if the test is neg, it doesn’t do a very good job at ruling out the condition
if something has high specificity it means
if the test is pos, it does a good job at ruling IN the condition
if something has LOW specificity it means
if the test is pos, it DOESNT do a good job at ruling IN
what is likelyhood ratio
Combines sensitivity and specificity
Gives probability before and after test result
Positive LR = increase in odds for the condition to be present
Negative LR = decreases odds for the condition to be present
LR of 1 = test neither proves nor disproves the condition
glucose below ___ you don’t touch them
60
what is macrocytic anemia
it when their red blood cell distribution is high (they have very large RBC, but there isn’t enough of them)
often associated with alcoholism
BBS ratings that indicate high risk of falls
BBS scores of 31 to 45 correlated with significantly higher rates of falls.
symbiosis vs pathogenic infection
symbiosis is good (microflora in gut)
pathogenic is bad - like strep
