Lab Values Flashcards
Albumin
3.5-5.5
Deficit decreases oncotic pressure and fluid shifts from vascular area to tissue
ABGs
pH 7.35-7.45
CO2 35-45
HCO3 22-26
O2 90-100
Blood values
Males: Hematocrit 42-52% Females: 35-45% RBC: 4.6-6.2 WBC: 5,000-10,000 Hgb: 13-18 male, 12-16 female
BUN
10-20
High value can cause confusion, disorientation, convulsions
Calcium
9-10.5 mEq/dL
Chloride
98-106 mEq/L
Cholesterol
Total < 200
Tri 50
Creatinine
0.5-1.2
CVP
3-12 cm water pressure
Fluid intake
1200-1500 ml in 24hr
ESR
0-20 mm/h
Indicates inflammatory or degenerative tissue destruction; patient may have acute febrile disease and may therefore be somewhat lethargic, confused, and weak
Intraocular pressure (IOP)
10-21 mm Hg
Lecithin/sphingomyelin (L/S)
Ratio of 3:1: Lungs adequately developed but c section for preterm infants
Magnesium
1.3-2.1mEq/L
Neonate
Resp 30-50
Phosphorous
3-4.5mEq/dL
Platelet count
150,000-400,000
Potassium
3.5-5 mEq/L Found in intracellular fluid Hypokalemia Weakness, premature PVCs, bradycardia Encourage foods high in potassium (avocados, broccoli, dairy products, dried fruit, cantaloupe, bananas)
PT
Coumadin
PTT
1.5-2x greater than normal
Heparin
Sodium
136-145 mEq/L
Found in extra cellular fluid
Hyponatremia=net gain of water because it moves from ECF to ICF causing cells to swell
Confusion, Tacycardia, orthostatic hypotension, decreased DTRs, seizures
Administer hypertonic fluid, Restrict water, encourage high salt foods and fluids (cheese, milk)
Hypernatremia=loss of water Confusion, tachycardia, orthostatic hypotension, decreased DTRs, thirst, oliguria, seizures Administer hypotonic (.45%) or isotonic fluids (0.9%), encourage water, discourage sodium intake
Troponin
0-0.3 normal
Specific gravity
1.010-1.020
Low would be more concentrated
Urine output
30 ml/hr
