Lab values

Question 1

Prothrombin time (PT) normal values

Answer 1

11-14 seconds

Question 2

what do the prothrombin/PTT measurements mean

Answer 2

if the blood takes longer than 14 seconds to clot, then the blood is thin. If blood takes shorter than 11 seconds to clot, then it is considered thick

Question 3

clotting/coagulation factors PT measures

Answer 3

I, II, V, VII, X

Question 4

Partial thromboplastin time normal values

Answer 4

25 to 35 seconds

Question 5

Clotting/coagulation factors that PTT measures

Answer 5

XII, XI, IX, VIII, X, V, II, I (fibrinogen)

Question 6

INR normal values

Answer 6

.8-1.2

Question 7

What is INR

Answer 7

the ratio of the patient’s clotting ability against the normal clotting ability. INR= PT patient/PT normal

Question 8

Platelet count normal values

Answer 8

150,000-450,000/ul of blood

Question 9

Fibrinogen normal values

Answer 9

150-400 mg/dl

Question 10

Normal Co2 level

Answer 10

35-45 mmHg

Question 11

goal for co2 level

Answer 11

keep it above 10 mmHg

Question 12

What is BUN used for?

Answer 12

To determine how well your kidneys are working.
It does this by measuring the amount of urea nitrogen in the blood. Urea nitrogen is a waste product that’s created in the liver when the body breaks down proteins. Normally, the kidneys filter out this waste, and urinating removes it from the body.

Question 13

Bun normal range

Answer 13

5-20 mg/dl

Question 14

Reticulocyte normal values

Answer 14

.5-2.5%

Question 15

What is reticulocyte a test of

Answer 15

immature red blood cells

Question 16

What does a low retic count tell you

Answer 16

iron deficiency anemia

Question 17

What does an elevated retic count tell you

Answer 17

hemolytic anemia, acute blood loss

Question 18

What does a low retic count tell you

Answer 18

anemia w infection, renal disease

Question 19

normal neutrophil count

Answer 19

1.5-8.5 the risk of infection goes up the lower the neutrophil count is

Question 20

Normal wbc

Answer 20

4,500-11,000

Question 21

What do neutrophils tests for

Answer 21

acute bacterial infection, inflammation, tissue death

Question 22

pH normal level

Answer 22

7.35-7.45

Question 23

Normal RBC values for men and women

Answer 23

4. 7-6.1 in males

4. 2-5.4 in females

Question 24

What is anion gap?

Answer 24

The difference between cations and anions in the blood

Question 25

What is the anion gap equation

Answer 25

(Na + K) - (Cl + HC03)

Question 26

What does a high anion gap mean

Answer 26

a larger proportion of our negative charge is not accounted for by the equation, meaning in a case of metabolic acidosis, the cause may be due to lactic acid build up (shock), ketoacidosis (diabetic), or methanol consumption.

Question 27

What does a normal anion gap acidosis mean

Answer 27

Normal anion gap acidosis: bicarb is decreased but body is compensating with Cl (kidneys inc CL reabsorption)

Question 28

What can cause normal anion gap

Answer 28

bicarp loss (diarrhea)

Question 29

Platelet normal value

Answer 29

> 100,000

Question 30

What does a chem 10 measure

Answer 30

Na, K, mg, Cl, bicarb, BUN, creatinine, glucose, calcium, phosphorus

Question 31

Potassium normal values

Answer 31

3.5-5.5meq
