The flashcards below were created by user mysty19 on FreezingBlue Flashcards. What would you like to do?


  1. Metabolic Alkalosis
    • heavy loss of acid or increased HCO3
    • increased pH
  2. Metabolic Acidosis
    • high acid content of blood=a loss Na HCO3
    • decreased pH
  3. Respiratory Alkalosis
    • decreased CO2
    • increase pH
    • hyperventilation
  4. Respiratory Acidosis
    • increased CO2
    • decreased pH
    • hypoventilation
  5. Bicarbonate (HCO3) abg
    22-26 mEq/L
  6. O2 Sat abg
    95%- 99%
  7. PaO2 abg
    80-100 mmHg
  8. PaCO2 abg
    35-45 mmHg
  9. pH abg
    7.35 -7.45
  10. BUN/Creatinine Ratio
    • 6:1 - 20:1
    • Increaed- dehydration or protein breakdown
    • Decreased- low protein intake, overhydration, liver failure
    • increase in both indicates renal failure
  11. Creatinine
    • 0.3-1.3 mg/dl
    • increased-damage to large number of nephrons(kidney's)
    • decreased- indicates atrophy of muscle tissue
  12. BUN
    • 5-25 mg/dl
    • increased- diseased or damaged kidneys
    • decreased renal perfusion (shock,CHF)
    • dehydration (lack of volume can't excrete waste)
    • high protein diet
    • bleeding in GI tract
    • decreased- over hydration
    • increase ADH
    • liver dysfunction
    • increased plasma volume(pregnancy)
  13. calcium (Ca2+)
    • 9-11 mg/dl
    • cell permeability
    • blood coagulation
    • nerve impulse transmission to myocardium and skeletal muscle
    • hypo-insufficient vit D, hypomagnesia, hyperphosphatemia(Ca2+ binds w/phosphate) hypoparathyroidism (controls Ca2+) protein malnutrition, renal failure
    • hyper- hyperparathyroidism, breast and lung CA, prolonged immobilization
  14. potassium (K+)
    • 3.5-5 mEq/L
    • Major intracellular electrolyte
    • neuromuscular and nerve impulse transmission
    • hypo-metabolic alkalosis, loop diuretics
    • hyper- tissue trama, renal failure, RBC hemolysis, potassium sparing diuretics
  15. sodium (Na+)
    • 135-145 mEq/L
    • nerve impulses
    • Regulation of ECF
    • major extracellular electrolyte
    • hyper-excess aldosterone secretion=saves salt
    • hypo- SIADH (dilution, not actually low)
  16. phosphate (PO43-)
    2.8-4.5 mg/dl
  17. Magnesium (Mg2+)
    • 1.5-2.5 mEq/L
    • Decreased levels= K+ leaving cell to be excreted by kidney
    • hyper-excess antacid/laxitive
    • hypo-ETOH abuse, renal disease
  18. chloride (cl-)
    • 95-105 mEq/L
    • bound with K+
    • maintenace of ECF
    • hypo-metabolic alkalosis
    • hyper- acidosis
  19. partial thromboplastin time (PTT)
    • 60-70 seconds
    • therapeutic 1.5-2 times normal
    • regulate heparin therapy
  20. prothrombin time (PT)
    • 11-12.5 seconds
    • therapeutic 1.5-2 times normal
    • regulate coumadin therapy
  21. platelet count
    • 1000/mm3
    • 150-400
    • values may increase with strenuous exercise high altitudes or oral birth control
    • may decrease with hemorrhage DIC infections prosthetic heart valves some drugs asa
  22. white blood cell count (WBC)
    • 1000/mm3
    • 5-10
    • stress exercise anesthetics and convulsions can increase values
  23. red blood cell count (RBC)
    • million/mm3
    • Male-4.7-6.1
    • Female-4.2-5.4
    • exercise and high altitudes can increase values
    • pregnancy usually lower
  24. Hematocrit (Hct)
    • Male-42%-52%
    • Female- 37%-47%
    • pregnant->33%
  25. Hemoglobin (Hgb)
    • g/dl
    • Male-14-18
    • Female-12-16
    • slight decreases if pregnant
    • high altitude living increases values
