Laboratory Testing

Question 1

Creatine

Answer 1

• measures kidney function and protein status

- Normal: 0.8 - 1.5 mg/dL

Question 2

Creatine

Answer 2

• measures kidney function and protein status

- Normal: 0.8 - 1.5 mg/dL

Question 3

Serum Albumin

Answer 3

• plasma protein produced by liver
• low levels = pressure sore severity, infection, starvation
• Normal: 3.5 mg/dL
• takes 21 days to asseess diet benefits

Question 4

Prealbumin

Answer 4

• transport protein
• Normal: 16-40 mg/dL
• affected by renal failure

Question 5

Serum Transferrin

Answer 5

• sensitive indicator of protein status

- malnutrition if levels are less than 170 mg/dL

Question 6

C-reactive protein

Answer 6

-increases associated with systemic inflammation

Question 7

Serum Cholesterol

Answer 7

-

Question 8

Hemoglobin & Hematocrit

Question 9

INR

Answer 9

monitors coumadin levels

Question 10

PTT

Answer 10

monitor heparin levels

Question 11

Blood Urea Nitrogen (BUN)

Answer 11

• 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

Question 12

BUN/Creatinine ratio

Answer 12

> 10:1 = skin tugor, urine ouput, and weight fluctuation indicators of dehydration

Question 13

Total Lymphocyte Count (TLC)

Answer 13

-indirect measurement of nutritional status and immune function
-Normal: 3000-3500 cells/uL
increased = infection
decreased = malnutrition

Question 14

Blood Glucose

Answer 14

-increased levels are associated with ulceration risk and impaired wound healing
Normal: 70-110, goal of

Question 15

Serum Albumin

Answer 15

• plasma protein produced by liver
• low levels = pressure sore severity, infection, starvation
• Normal: 3.5 mg/dL
• takes 21 days to asseess diet benefits
