  8. Phosphate lab values
    2.5 - 4.5 mg/dL
  9. Digoxin
    • heart medication
    • treats heart failure and heart rhythm problems
    • must be tested to monitor concentration, as it has a narrow safe range
  10. Digoxin levels
    • normal is 0.5 - 2
    • Toxic os >2
  11. low levels of digoxin
    • s/s of persistent HF
    • SOG
    • changes in heartbeat
  12. high, or toxic digoxin
    • YELLOW-tinted vision
    • N/V
    • confusion
  13. Antidote for Digoxin
    • Digibind (Digoxin Immune Fab)
    • Binds to and inactivates digoxin
  14. Lithium
    • treats manic episodes of bipolar disorder
    • serum level needs to be monitor
  15. Lithium levels
    • normal  0.6 - 1.2 mEq/L
    • Toxic > 1.5
    • Lethal > 3.4
  16. treatment for high lithium levels
    • No antidote, hold med
    • correct water and sodium deficits
  17. Normal range for specific gravity
    1.002 - 1.030

    The higher the number, the more dehydrated you may be
  18. range for hemoglobin
    • Men: 14 - 18 g/dL
    • Women:  12 - 16 g/dL
  19. Hematocrit
    • Men: 38 - 50%
    • Women: 35 - 45%
  20. Normal range of platelets
    150 - 450
  21. Neutrophils
    • 45 - 70%
    • most abundant WBC
  22. Lymphocytes
    20 - 40%
  23. RBC
    • Male:  4.3 - 5.7
    • Female:  3.9 - 5.0
  24. ESR
    • Erythrocyte sedimentation rate
    • Rate at which RBC sediment (settle to bottom of tube) in a period of an hour
    • Non-specific measure of inflammation
  25. Normal range for ESR
    • Male: 15 mm/hr
    • Female: 22 mm/hr
  26. PPT
    • Partial thromboplastin time... measures time it takes for blood to clot
    • 25 - 35 seconds
  27. PT/INR
    • INR is international normalized ration
    • Calculation based on results of PT and used to monitor effectiveness of warfarin
    • Desired is 2.0 - 3.0
  28. Dilantin
    anticonvulsant drug

    • dose is 10-20 mcg/mL
    • Toxic is >30
    • Btwn 40 and 50: lethargy and confusion
    • Higher than 50: coma and seizures
  29. Antidote for dilantin
    • no specific antidote
    • treatment is supportive
  30. Theophylline
    bronchodilator

    • dosage depends on patient
    • Therapeutic level: 10 - 15 mcg/mL
    • Toxic: >20 mcg/mL
  31. Antidote for theophylline
    • Administer activated charcoal, which enhances elimination
    • Very effective, but important to control N/V in order for charcoal to work
  32. Glucose levels
    • fasting: 70 - 100
    • casual: <200
    • critical: <50 to 400
  33. Hgb A1c
    • Hemoglobin A1c
    • measures how much glucose is stuck to RBC's, also tells how well pt diabetes has been controlled in last 2-3 months

    • Normal range 4 - 5.9%
    • Ideal for diabetics
  34. Total cholesterol
    • <200 is desirable
    • 200 - 239 is borderline high
    • 240 and above is high risk
  35. PaO2
    80 - 100 mmHg

    • PaO2 is partial pressure of O2 in arterial blood in mmHg measurement
    • SaO2 is arterial O2 that is saturated on RBC
  36. PaCo2
    • 35 - 45 mm Hg
    • <35 is Alkaline
    • >45 is Acidic
  37. HCO3 normal range
    22 - 26 mEq/L

    • <22 is Acidic
    • >26 is Alkaline
  38. What happens when PaCo2 is high
    • When PaCO2 levels are abnormally high (like COPD), pH drops which means it goes acidic
    • Respiratory acidosis result
  39. What is PaCO2 is low?
    • This can be triggered by hyperventilation for instance...
    • Causes pH to rise cause your blowing off too much CO2, becoming alkaline
    • Leads to respiratory alkalosis
  40. What if HCO3 levels increase
    • The pH will rise since HCO3 is an alkaline substance
    • Metabolic alkalosis
  41. What if HCO3 levels decrease
    • pH will drop (since HCO3 is alkaline) and will become acidic
    • Metabolic acidosis develops
