1

Sodium (Na)

135-145 mEq/L

Regulates the amount of water that’s in and around the cells
-Blood pressure and volume maintenance
-Plays a major role in nerve conduction

2

Potassium (K)

3.5-5.0 mEq/L

Regulates water and acid-base balance
-Heart needs potassium to maintain rhythm and regulate BP

3

Calcium (Ca)

8.5-10.2 mg/dL

-Bone/teeth structure
-Cell signaling
-Blood clotting,
-Muscle contraction/nerve function

4

Magnesium (Mg)

1.5-2.5 mEq/L

-Nerve and muscle function
-Heart rhythm
-Immune function
-Production of blood glucose levels, energy, and protein

5

Phosphorus (P)

2.5 to 4.5 mg/dL

-formation of bones and teeth
-growth and repair of cell tissues
-used in the body’ process of making use of carbs and fats

6

Albumin

3.5-5.5 g/dL

-main protein produced by the liver, maintains intravascular colloid osmotic pressure (aka helps the fluid stay in your vasculature and not leak into tissues)

7

PT (prothrombin time)

11-13.5 seconds

8

PTT/aPTT
(Activated) Partial Thromboplastin Time

PTT= 60-70 seconds
aPTT= 30-40 seconds

test that takes a patient’s blood and add’s a substance and then measure’s the amount of time it takes for the blood to clot

9

INR
(International normalized ration)

2.0-3.0

Test used to measure the time it takes for blood to clot
-often used for people taking Warfarin

10

Platelets

150,000-450,000 µL

cells found in the blood that bind together to form clots during injury- help w healing but also responsible for producing blood clots

11

FSP/FDP/d Dimer

Less than or equal to 500 ng/mL

D Dimer test is used to indicate the presence of fibrin degradation products (FDP)
-when levels are above the expected, this means pt may have a blood clot or PE

12

pH

7.35-7.45

13

HCO3 (this is bicarbonate)

22-28 mmHG

14

paCO2

35-45 mmHG

15

SaO2

97% or above

16

WBC

4,500-11,000

-cells of the body involved in protecting against infectious disease and foreign invaders

17

Absolute Neutrophil Count (ANC)

2500-6000

measure of the number of neutrophil granulocytes present in the blood; taken from the overall WBC count

18

Hgb (hemoglobin)

Women: 12.0-15.5
Men: 13.5-17.5

Measure of the protein in the blood that carries O2 throughout the body

19

Hct (hematocrit)

Women: 37-48%
Men: 45-52%

determines the percentage of RBCs in the blood

20

CK-MB

0% of total CK
30-170 u/L

cardiac enzyme that is released into the bloodstream when the heart muscle suffers ischemia
-helps diagnose MI

21

Troponin

<0.5 ng/ML

cardiac enzyme that is released into the bloodstream when the heart muscle suffers ischemia
-helps diagnose MI

22

Lipid Panel
Cholesterol, LDL, HDL, Triglycerides

-Cholesterol: <200 mg/dL

-LDL:
<130 mg/dL

-HDL:
females- >55 mg/dL
males- > 45 mg/dL

-Triglycerides:
males- 40-160 mg/dL
females- 35-135 mg/dL

23

BUN

??????

results from breakdown of protein in liver, creating the byproduct of urea nitrogen

24

Creatinine

*generally 0.8-1.4*

0.6-1.2 mg/dL in males
0.5-1.1 mg/dL in females

-results from protein and muscle breakdown

25

Urinalysis

pH: 6.5-7.5
WBC: can indicate infection
RBC: can indicate infection
Ketones and
Nitrates: any presence of these can indicate DM, fat metabolism, infection, cancer

26

Phenytoin

10-20 ug/mL

used for management of seizures

27

Digoxin

0.5-0.8 ng/mL

cardiac glycoside; increased force of myocardial contraction
-decreases heart rate

28

Lithium

5-15 mcg/mL

bronchodilator
-long term control of COPD or asthma

30
