nursing lab values

sodium

135-145 mEq/L

maintains osmotic pressure and acid-base balance

assists with transmission of nerve impulses

absorbed from the small intestine.

potassium (k)

3.5-5.1 mEq/L

regulates cellular water ba;ance,electrical conductionin muscle cells.

used to regulate cardiac, renal, gi function.

pts with elevated wbc may have altered k levels.

chloride

98-107 mEq/L

most abundant anion in extracellular fluid

functions to counter balance cations (sodium)

aids in digestion and maintaining osmotic pressure

bicarbonate

22-29 mEq/L

responsible for maintaining the ph of body fluids

prolonged tourniquet application before blood draw increases bicarb level

aPPT

20-36 SEC

used to moniter heparin ( anticoagulant) therapy

PT

male: 9.6-11.8 sec female: 9.5-11.3 sec

measures the amount time it takes for clot formation.

platelet count

150k-400k

high altitudes, chronic cold weather and excercise increase platelet counts

male: 65-175 mcg/dl

female: 50-170 mcg/dl

mostly found in hemoglobin

rbc

formed by bonemarrow life span of 120 days

removed from blood from speen, liver and bone marrow

creatine kinase (ck)

26-174 units/L

troponins

troponin i: > 1.5 indicates MI

troponin t: > 0.2 indicates MI

regulartory proteins found in striated muscle (skeletal & myocardial)

albumin

3.4-5g/dl

a main plasma protein of blood

ammonia

35-65 mcg/dl

a waste product from nitrogen breakdown during protein metabolism.

bilirubin

low density lipids

< 130 mg/dl

bad cholesterol

high density lipid

30-70 mg/dl

good cholesterol

protein

6-8 g/dl

reflects total amount of albumin and globins in serum

uric acid

2.5-8 mg/dl

elevated amounts deposit in joints and soft tissue and cause gout.

fasting gluclose

gluclose tolerance test, oral

baseline: 70-110

30 min: 70-110

60 min:110-170

90 min: 100-140

creatine

0.6-1.3 mg/dl

very specific indicator of renal function

bun

8.6-10 mg/dl

blood urea nitrogen

calcium

8.5-10.5

aids in clotting by converting prothrombin to thrombin

magnesium

1.6-2.6

needed ofr blood clotting process

phosphorus

2.7-4.5
