    • < 3.5 HYPOKALEMIA diarrhea, vomiting, diuretic therapy
    • >5 meq HPERKALEMIA burns, renal failure
  2. What is the normal lab value and extremes for:

    TOTAL serum calcium (Ca)
    • NORMAL: 8.9-10.1 mg/dL
    • HYPOCALCEMIA: <8.9 mg/dl (acute pancreatitis)
    • HYPERCALCEMIA: >10.1 mg/dl (hyperparathyroidism)
  3. What is the normal lab value and extremes for:

    IONIZED calcium (Ca)
    • NORMAL: 4.4 -5.3 mg/dl
    • HYPOCALCEMIA: <4.4 massive transfusion
    • HPERCALCEMIA:>5.3 Acidosis
  4. What is the normal lab value and extremes for:

    serum phosphates

    serum chloride
    • NORMAL: 98-108 meq/l
    • HYPOCHLOREMIA: <98 prolonged vomiting
    • HYPERCHLOREMIA: >108 hypernatremia
  7. In ABG, what are the normal values...

    pH:
    PaCo2
    Bicarb
    02
    • pH: 7.35-7.45
    • PaCo2: 35-45 mm Hg
    • Bicarb: 22-26 meq/l
    • O2: >92%
  8. Respiratory acidosis:
    Increase in Hydrogen ions, PH less than 7.35, carbonic acid excess, CO2 pressure increased above 45 mmhg.Causes: Pneumonia, PE, Aspiration, near drowning, COPD, asthma, emphysema, overdose, brain injury , chest injuryS/S: confusion, Lethargy, headache, convulsions, ABG abnormal, Pulse/ RR may increase or decreaseTx: May be mechanical ventilation, oxygen, breathing tx etc.
  9. Acidosis Respiratory:
    Metabolic:
    • PH<7.35, PCO2>45,
    • HCO3 = normal,
    • BE= Normal

    • Metabolic: PH<7.35,
    • PCO2= Normal,
    • HCO3<21meq,
    • BE<3.0
  10. Alkalosis Respiratory:
    Metabolic:
    • PH>7.45,
    • PCO2<36,
    • HCO3=Normal,
    • BE = Normal

    • Metabolic: PH>7.47,
    • PCO2=Normal,
    • HCO3>29meq,
    • BE>3.0
  11. Respiratory alkalosis
    Carbonic acid deficit, PH>7.45 , decrease in H+ ions, CO2 <3mmhg

    Causes: Hyperventilation, salicylate overdose, over-ventilation, brain stem injury, Hyperthyroidism, infections

    S/S: SOB, light headed, LOC changes, fainting, blurred vision

    Tx: Breathing into a paper bag, correct underlying causes
  12. Hypovolumia signs and symptoms
    • Dry skin,
    • Hypotension,
    • Tachycardia,
    • Low urine output, Increased urine Specific gravity,

    • Dry skinWt. lossBP decreasesIncreased HRLow urine outputConcentrated urine Increased specific gravityDizzy/weak pulse
  13. Hypovolumia RISK FACTORS
    vomiting, diarrhea, polyuria, fever, NG suction, bleeding, third spacing, anorexia, nausea
  14. Hypervolumia RISK FACTORS
    excessive intake of NACL, rapid administration of IV fluids, cirrhosis of liver, renal failure, & CHF.
  15. Hypervolumia SIGNS AND SYMPTOMS
    Sudden Wt. gain, distended Jugular veins, tachycardia, bounding pulse, output increased/decreased, edema, rales/crackles
  16. Hyponatremia
