Flashcards in Basic Lab Test Deck (38):
1

what is a normal range of serum K+

3.5-5.0

2

what are some potential errors that could result in a falsely high level of K+

improper technique of blood draw, results in RBC hemolysis.....

3

how would we define abnormal in terms of standard deviation

anything outside 2 (+/-) from the SD

4

Normal range for WBC

4,000-10,000 or (4.0-10.0mm^3)

5

what would a raised WBC indicate

moderate/severe bacterial infection

6

how would we treat elevated WBC

antibiotics/ surgery

7

What would a depressed WBC indicate

suppression of bone marrow (where its made)

8

what are some examples that would suppress bone marrow cause a low WBC count

HIV/AIDS, chemotherapy, toxins, MONO (viral infection) overwhelming sepsis

9

WBC differential is used for what

certain subcategories would indicate different diseases

10

Hematocrit range?

36-45% (roughly 3x's Hgb)

11

how can we calculate Hct after sample blood taken and spun in centrifuge

Volume RBC's / total volume X 100

12

how can the Hct calculation be a problem? or incorrect

We are assuming the RBC have normal amount Hgb; anemia (normal #RBC but don't carry Hgb) If RBC are small in size- the Hct may be low, but Hgb normal. If RBC's are macrocytic Hct normal, but Hgb may be low

13

hemoglobin range

12.5-16

14

platelet count range

150,000-400,000

15

Serum Glucose Normal

60-100

16

BUN

8-25 mg/dl

17

Creatinine

.8-1.4 mg/dl

18

Sodium serum levels

134-146 mEq/l

19

Chloride

97-110

20

HCO3-

18-28

21

HOw would chronic hypoxia affect Hgb levels?

it would raise levels

22

what conditions would cause chronic hypoxia

living at high altitude & COPD

23

what is polycythemia

too many RBC's

24

how does polycythemia affect Hgb

raises

25

What is a normal Albumin range

3.5-5.5

26

How could dehydration affect a Hct

raise it because of the concentration of RBC's would technically be higher not the actual #'s

27

What would a comprehensive metabolic panel measure

Serum electrolytes, Liver panel, Renal function, and Glucose

28

What would you expect in a specific gravity if your urine was isotonic with normal serum osmolarity of 295 mOsm/l

1010

29

List abnormal constituents in the urine

protein, glucose, bilirubin, blood, casts, crystals, RBC/WBC

30

You are looking at normal levels of total protein (6-8.5) Albumin (3.5-5.5) and Globulin (1.5-4.5). What is this an indication of

liver function is normal

31

What four things would you measure to test whether or not liver inflammation is present?

Enzymes: AST, ALT, bilirubin, Alkaline Phosphatase(bone too)

32

What would cause increased levels of enzymes in the liver

hepatitis, tumor, bile blockage, alcohol

33

Normal total protein count

6-8.5

34

Globulin count (also immune system)

1.5-4.5

35

AST

0-40

36

ALT

0-55

37

Bilirubin

.0-1.2

38

alkaline phosphatase

25-150
