2

What is a normal total red blood cell count in men?

4.5-6.2 million/mm3

3

What happens if total red blood cell count is low?

may be anemic, or may have lost blood volume

4

What happens if total red blood cell count is high?

May be dehydrated or at risk for blood clots

5

What is a normal hematocrit level in women?

38-46%

6

What is a normal hematocrit level in men?

42-54%

7

What happens if hematocrit is low?

may have anemia, blood loss, or malnutrition

8

What happens in hematocrit is high?

may be dehydrated or at risk for blood clots

9

What is a normal hemoglobin level in women?

12-16 g/dL

10

What is a normal hemoglobin level in men?

14-18 g/dL

11

What happens if hemoglobin is low?

possible blood loss or nutritional deficiency

12

What happens if hemoglobin is high?

possible dehydration or risk for blood clot

13

4500-11000/mm3

14

What happens if white blood cell count is low?

risk for infection

15

What happens if white blood cell count is high?

possible infection, inflammatory response, or anemia

16

What is a normal platelet (throbocyte) count?

150,000-400,000

17

What happens if platelet (thrombocyte) count is low?

delayed clotting

18

What happens if platelet (thrombocyte) count is high?

potential for blood clots

19

What is a normal total lymphocyte (TLC) count?

>1,800 cells/mm3

20

What happens if total lymphocyte (TLC) count is low?

decrease immune function, may have protein deficiency, can delay wound healing

21

What is a normal serum albumin count?

3.5-5.5 g/dL

22

What happens if serum albumin is low?

may be malnourished, may cause tissue edema, may be a sign of metabolic stress or inflammation.... correlated with pressure ulcer severity

23

What happens if serum albumin is high?

may be dehyrdated

24

What is a normal serum prealbumin level?

16-40 mg/dL

25

What happens is serum prealbumin is low?

may be malnourished, may be a sign of metabolic stress or inflammation, mortality rate increases as prealbumin decreases

26

27

What happens if serum transferrin is low?

may have protein deficiency or may be malnourished

28

What happens if serum transferrin is high?

may have iron deficiency

29

What happens if blood glucose is high?

may have poorly controlled diabetes

31

What is a normal urine glucose level?

32

What happens if urine glucose is present?

may have poorly controlled diabetes or kidney disease

33

What is a normal BUN (blood urea nitrogen) level?

8-20 mg/dL

34
