1532597815 | *Diuretics | Agents that increase Urine Output, increases the excretion of solutes and water, Main purpose: eliminate excess fluid from the body | 0 | |
1532597816 | *Primary goal of diuretic therapy | reduce extracellular fluid volume in order to: Lower blood pressure, Rid body of excess interstitial fluid | 1 | |
1532639615 | *Kidneys | are paired retroperitoneal organs, Perfused by renal artery, Active organ (not a passive filter) | 2 | |
1532639616 | *Nephron | is the Functional unit of the kidney, is composed of the glomerulus, proximal tubule, loop of henle, distal tubule and collecting duct. | 3 | |
1532639617 | *Glomerulus (filtrate) | filtration of fluid from the blood to the tubule occurs here, more than 99% is reabsorbed and less than 1% is excreted as urine | 4 | |
1532639618 | *Oliguria | Urine output < 30 - 60 mL/hr | 5 | |
1532639619 | *Anuria | No urine output | 6 | |
1532639620 | *Polyuria | Urine output > 60 mL/hr | 7 | |
1532639621 | *Na+ (Sodium) | 70% of this is reabsorbed in the proximal tubules, 20% in loops of Henle, 10% in distal tubules, Inhibition causes less H2O retention | 8 | |
1532639622 | *Aldosterone | Increases Na+ and H2O reabsorption in the Distal Tubule | 9 | |
1532639623 | Spironolactone | is a diuretic that increases Na+ and H2O loss by inhibiting aldosterone | 10 | |
1532639624 | *Diuretics | are relevant to respiratory and critical care clinicians to treat hypertension and congestive heart failure (CHF) | 11 | |
1532639625 | *Osmotic (diuretic group) | impairs proximal tubule and descending limb of loop of Henle to reabsorb NaCl | 12 | |
1532639626 | *Carbonic Anhydrase inhibitors (diuretic group) | treats glaucoma, metabolic alkalosis, and altitude sickness, potential for metabolic acidosis-limits use, Hypokalemia is a common adverse effect, Decrease HCO3- and NaCl reabsorption (within proximal tubule) | 13 | |
1532639627 | *Thiazides (diuretic group) | block NaCl reabsorption at the Distal Tubule, Not much difference between minimal and maximal doses | 14 | |
1532639628 | *Loop(diuretic group) | inhibit NaCl reabsorption at the Thick Ascending Limb of Henle, "High-ceiling" diuretics, Up to 20% of NaCl and H2O is lost | 15 | |
1532639629 | *Potassium-Sparing (diuretic group) | block exchange of Na+ for K+ and H+, Weak action, in collecting duct, May cause hyperkalemia | 16 | |
1532639630 | *Adverse Effects of Diuretics | Hypovolemia (low fluid volume), electrolyte and acid-base disorders are most common | 17 | |
1535669539 | *Chloride and bicarbonate | Cl- and HCO3- are passively reabsorbed in the proximal and distal tubules | 18 | |
1535669540 | *Potassium | most filtered K+ is reabsorbed in the proximal tubules, found in urine | 19 | |
1535669541 | *Mannitol | is an Osmotic Diuretic and is typically a selected agent because of its lower toxicity | 20 | |
1535669542 | *Hypovolemia | when sodium and fluid excretion exceed intake | 21 | |
1535669543 | *Hypokalemia | low potassium levels in the body | 22 | |
1535669544 | *Glucose changes | the average increase in serum glucose is 6.5 to 9.6 mg/dL, associated with diabetic ketoacidosis | 23 | |
1535669545 | *Ototoxicity | hearing loss, reducing the infusion rate or administering the drug orally may alleviate the hearing loss | 24 |

Need Notes?
While we strive to provide the most comprehensive notes for as many high school textbooks as possible, there are certainly going to be some that we miss. Drop us a note and let us know which textbooks you need. Be sure to include which edition of the textbook you are using! If we see enough demand, we'll do whatever we can to get those notes up on the site for you!
