    Hypokalemia - Deficiency of K+ in serum

    Hypocalcemia - Deficiency of Ca+ in serum
  21. Acid-base Disorders
    Respiratory Acidosis - Too much CO2 not removed from the body via hypoventilation

    Respiratory Alkalosis - Low levels of CO2 in the body via hyperventilation

    Metabolic Acidosis - Excessive acidity in the blood via kidney disease

    Metabolic Alkalosis - High levels of alkaline substance caused by vomiting
  22. Cardiovascular Dysfunction

    • Hypertensin
    • Shock
  23. Renal Dysfunction
    Infection or inflammation in the nephritism, glomerulonephritis and pylonephritis
  24. Changes in urine output
    • Oliguria - decreased
    • Anuria - no urine
  25. Increase ammonia levels
    Uremia/toxemia - accumulation of nitrogenous waste products
  26. Increase in flood fluid levels

    Remove excess abdominal fluid back into circulation
  33. How do diurectics help Edema?
    Pull excess fluid out of interstitial tissues and back into the systemic circulation
  34. How does diuretics help Nephrolithiasis?
    Promote excretion of salts
  35. Type of Diurectic
    Osmotic Diurectics work on the PCT
  36. Anuria
    Failure of kidney to produce urine
  37. Osmotic Diurectics used to treat intra-ocular & intra-cranial pressure
    Mannitol - Osmitrol

    Do Not dispense if crystals are present
  38. Drugs for Sodium Re-absorption Inhibitors and mechanism/side effect
    Bumetanide - Burinex

    Furosemide - Lasix

    Blocks re-absorption of Na+ @ Loop of Henle "Loop Diurectics"

    SE: Hypokalemia
  39. Anuria
    Failure of the kidneys to produce urine
  40. Thiazide & thiazide-like diurectics:
    Side Effects
    Blocks re-absoprtion of Na+ @ DCT

    Chlorothiazide - Diuril

    Chlorthalidone - Hygroton

    Metolazone - Zaroxolyn

    Hydrochlorothiazide - Orectic, Esidrex, Hydrodiuril, Microzide

    SE: Photosensitivity for Metolazone & Hydrochlorothiazide
  41. Mannitol
  42. Bumetanide
  43. Furosemide
  44. Chlorothiazide
  45. Chlorthalidone
  46. Metolazone
  47. Hydrochlorothiazide
    • Oretic
    • Esidrex
    • Hydrodiuril
    • Microzide
  48. Aldosterone Antagonists:
    Side Effect
    Promotes elimination of Na+ and reabsorption of K+

    Spironolactone - Aldactone

    SE: Gynecomastia (man boobs)

    Eplenerone - Inspra

    SE: K+ Sparring

    Triametene - Dyrenium

    SE: Photosensitivity
  49. Diuretic Combinations:
    (whole sentance)
    Since the primary side effect of the thiazides is hypokalemia & primary side effect of the aldosterone antaonists is hyperkalemia, combining the two diurectics increases the therapeutic effects and decreases side effects. These agents are primarily active in the distal tubule.
  50. Diurectic Combinations Drugs
    • Triamterene and Hydrochlorothiazide
    • - Dyazide, Maxzide
  51. Additional Diurectic
    Lozol - Indapamide
  52. Carbonic Anhydrase Inhibitors
    Inhibits carbonic anhydrase in the PCT to cause re-absorption of C2O4

    Acetazolamide - Diamox

    • Reduces eye pressure for patient going into surgery
    • Acute Mountain Sickness
  53. Anti-Diurectics
    Suppresses urine and rate of excretion

    • Vasopressin - Pitressin
    • Diabetes insipidue & vascoconstrictor in shock

    • Desmopressin - DDAVP, Stimate
    • Nocturnal Enuresis, Diabetes Insipidus
  54. What's the 4 functions of the renal system?
    • 1. Filters blood to remove waste
    • 2. Regulates water balance through hormone production
    • 3. Regulates electrolyte balance
    • 4. Regulates acid base balance
