    • overweight: 25-29.9
    • obese I: 30-34.9
    • obese II: 35-39.9
    • extreme obese III: >40
  9. Na
    • 135-147 mEq/L
    • sxs hyper: AMS, decreased urine output, lethargy, seizures, thirst

    sxs hypo: AMS, seizures, disorientation, muscle cramps

    Trileptal and tegretol decrease Na

    indicates fluid balance
  10. K
    3.5-5mEq/L

    sxs hyper: cardiac arrhythmia, bradycardia, hypotension

    sxs of hypo: cardiac arrhythmia, muscle weakness/cramp, fatigue

    ACEI/ARB increase K, diuretics decrease K
  11. Mg
    1.5-2.3 mEq/L

    sxs hyper: cardiac arrhythmias, sedation, lethargy, muscle weakness

    sxs hypo: cardiac arrhythmias, tetany, muscle irritability, N/V

    renally excreted
  12. Ca
    8.6-10.2 mg/dL

    sxs hyper: weakness, anorexia, constipation, N/V

    sxs hypo: muscle cramps, tingling fingers, tetany, seizures

    important in neuromuscular fxn, bone formation, need to correct for low albumin
  13. BUN/SCr
    BUN: 8-18 mg/dL

    SCr: 0.6-1.2 mg/dL
  14. CrCl
    75-125 mL/min
  15. Kidney dysfunction
    • Stage I: kidney dmg w/ normal gfr
    • ClCr >90

    • Stage II: dmg with mild reduction in GFR
    • ClCr 60-80

    • Stage III: dmg with moderate reduction in GFR
    • ClCr 30-59

    • Stage IV: dmg with severe reduction in GFR
    • ClCr 15-29

    • Stave V: Kidney Failure
    • ClCr <15
  16. AST (Aspartate aminotransferase)
    ALT (Alanine aminotransferase)
    • AST: 0-40 IU/L
    • Found primarily in heart/liver, increased in MI and acute hepatic necrosis

    • ALT: 0-40 IU/L
    • Found primarily in liver, more sensitive to hepatic dmg than AST
  17. AlkPhos (alkaline phosphatase)
    30-120 IU/L

    Increased in hepatitis, liver diease, pancreatitis, bone disorders

    • Use 2ndary GGT test
    • high AlkPhos+GGT = liver disease
    • high AlkPhos + Normal GGT = bone disorder
  18. Albumin
    4-6 g/dL

    decreased: overhydration, malnutrition, cancer, severe burns, pregnancy, cirrhosis, hepatitis, liver failure

    hypoalbuminemia: leads to edema and ascites
  19. Amylase
    Lipase (more specific)
    amylase: 30-100 IU/L

    Lipase: 0-160 IU/dL

    high in pancreatic injury, acute pacreatitis, obstruction of pancreatic duct by gallstone/tumor
  20. TSH/T3/T4
    TSH: 0.3-5 uIU/L

    • T4 5-12 ug/dL
    • Free T4 0.8-2.2 ng/dL

    T3: 75-200 ng/dL
  21. RBC
    M: 4.3-5.9 x 10^6/mm^3

    F: 3.5-5 x 10^6/mm^3

    use Hgb and Hct to monitor qualitative changes in RBCs
  22. Hgb/Hct
    • Hgb:
    • M: 14-18 g/dL
    • F: 12-16 g/dL

    • Hct:
    • M: 40-50%
    • F: 34-47%

    increased in dehydration
  23. MCV (mean cell volume)
    75-100 fL/cell

    describes cell size (MCV = Hct/RBC)

    • if H/H are low:
    • MCV low: microcytic anemia, iron deficiency
    • MCV high: macrocytic anemia, folic acid deficiency
  24. Platelets
    150-400 x 10^3/mm^3

    • high: thrombosis/clot formation
    • low: excessive bleeding (can be drug induced, heparin, bactrim, ASA)

    targeted by Plavix (anticoag)
  25. WBC
    3.5-10 x 10^3/mm^3

    high: leukocytosis from infxn, sepsis, leukemia

    low Leukopenia, drug induced or disease, at risk for infxn

    "left shift": increase in bands (immature WBC to fight off an infxn)
  26. ANC
    Neutropenia: <2000

    ANC <1000 at risk for infxn

    Agranulocytosis: <500 (high risk of infxn)
  27. Phenytoin
    10-20 mcg/mL

    • If low albumin, adjust levels
    • adjusted PHT = PHT/(0.2*alb + 0.1)

    toxicity: slurred speech, ataxia, confusion, nausea, nystagmus
  28. Vancomycin
    10-20mcg/mL

    toxicity: ototoxicity, nephrotoxicity, vertigo, dizziness, tinnitus
