Laboratory Testing Flashcards
1
Q
Creatine
A
- measures kidney function and protein status
- Normal: 0.8 - 1.5 mg/dL
2
Q
Creatine
A
- measures kidney function and protein status
- Normal: 0.8 - 1.5 mg/dL
3
Q
Serum Albumin
A
- plasma protein produced by liver
- low levels = pressure sore severity, infection, starvation
- Normal: 3.5 mg/dL
- takes 21 days to asseess diet benefits
4
Q
Prealbumin
A
- transport protein
- Normal: 16-40 mg/dL
- affected by renal failure
5
Q
Serum Transferrin
A
- sensitive indicator of protein status
- malnutrition if levels are less than 170 mg/dL
6
Q
C-reactive protein
A
-increases associated with systemic inflammation
7
Q
Serum Cholesterol
A
-
8
Q
Hemoglobin & Hematocrit
A
9
Q
INR
A
monitors coumadin levels
10
Q
PTT
A
monitor heparin levels
11
Q
Blood Urea Nitrogen (BUN)
A
- urea is by-product of protein metabolism by kidney
- indicators renal function
- Normal: 5-25 mg/dL
- elevated levels are associated with decreased wound healing
12
Q
BUN/Creatinine ratio
A
> 10:1 = skin tugor, urine ouput, and weight fluctuation indicators of dehydration
13
Q
Total Lymphocyte Count (TLC)
A
-indirect measurement of nutritional status and immune function
-Normal: 3000-3500 cells/uL
increased = infection
decreased = malnutrition
14
Q
Blood Glucose
A
-increased levels are associated with ulceration risk and impaired wound healing
Normal: 70-110, goal of
15
Q
Serum Albumin
A
- plasma protein produced by liver
- low levels = pressure sore severity, infection, starvation
- Normal: 3.5 mg/dL
- takes 21 days to asseess diet benefits
