Show Answers:

  1. Sodium
    135-145 meq/L
  2. Potassium
    3.5-5.0 meq/L
  3. Calcium
    8- 10 mg/dL
  4. Magnesium
    1.8-2.4 mg/dL
  5. Phosphorus
    2.5-4.5 mg/dL
  6. Creatinine
    0-1 mg/dL

    The blood creatinine level shows how well your kidneys are working. A high creatinine level may mean your kidneys are not working properly. The amount of creatinine in the blood depends partly on the amount of muscle tissue you have
  7. BUN
    • 10-30 ug/dL (6-20 mg/dL)
    • BUN measures the ammount of urea in your blood and tells you how well the kidneys are working
    • Increased: low blood flow to kidneys from dehydration, heart failure. high protein diet
    • Decreased: malnutrition, severe liver damage, over hydration
  8. paCO2
    35-45 mmHg

    The ammount of CO2 dissolved in arterial blood.
  9. paO2
    greater than 80 mmHg

    The partial pressure of oxygen dissolved in arterial blooed
  10. HC03 (bicarb)
    22-26 mmHg

    • Altered levels of Bicarb mean the body is having trouble maintaining acid base balance.
    • Increased could be from: severe vomiting, metabolic alkalosis, Cushing Syndrome.
    • Decreased could be from: chronic diarrhea, metabolic acidosis, Aspirin OD.
  11. RBC in males
    4.6-6.2 mil/mm3
  12. RBC in females
    4.2-5.4 mil/mm3
  13. WBC
    4800-10800 mm3
  14. Hemoglobin in males
    Hematocrit in males
    • 13-18 g/dL
    • 42-52%

    percentage of blood volume occupied by RBC.
  15. Hemoglobin in women
    hematocrit in women
    • 12-16 g/dL
    • 37-48%
  16. Glycosolated Hemoglobin (Hgb A1C)
    5% (up to 7% in a diabetic)
  17. Erythrocyte Sedementation Rate (ESR)
    • less than 20 mm/hr
    • It is a test that indirectly measures how much inflammation is in the body.

    • Increased: systemic infection, Tb, Infection of heart valves
    • Decreased: CHF, polycythemia, sickle cell
  18. Bleeding Time
    • 4-7 min
    • Bleeding time is a blood test that looks at how fast small blood vessels in the skin close to stop you from bleeding.
  19. Platelets
    150,000-450,000 mm3
  20. Prothrombin time (PT)
    • 11-14 seconds
    • A prothrombin time test can be used to check for bleeding problems. PT is also used to check whether medicine to prevent blood clots is working.
    • **PT is used to check coumadin/warfarin
  21. Partial Thromboplastin time
    • less than 40 seconds
    • too long of a PTT: DIC, Hemophilia A or B, Vitamin K deficiency, liver disease
    • ** check PTT for heparin
  22. albumin
    • 3.8-5.0 g/dL
    • Albumin is a protein made by the liver. A serum albumin test measures the amount of this protein in the clear liquid portion of the blood.
    • decreased levels: kidney disease, liver disease, low protien diet
  23. Ammonia
    • 11-35 umol/L
    • high levels: liver disease, kidney failure, heart failure, severe bleeding from stomach and intestines
  24. Total bilirubin
    0-1.5 mg/dL
  25. Urine Specific Gravity
    • 1.010-1.030
    • Urine specific gravity is a laboratory test that measures the concentration of all chemical particles in the urine.
    • decreased: kidney infection, renal failure, excessive fluid intake
    • increased: Syndrome of inappropriate antidiuretic hormone, dehydration, heart failure
  26. Urine pH
    • 4.5-7.5
    • high pH (alkaline): gastric suction, UTI, kidney failure
    • low pH (acid): diabetic ketoacidosis, starvation, diarrhea
  27. therapeutic digoxin level
    0.8-2.0 ng/mL
  28. therapeutic lithium level
    0.8-1.2 meq/L
