4 True/False Questions
Carbonic anhydrase inhibitors (7) → -Carbonic anhydrase is an enzyme that affects acid-base balance by its ability to form carbonic acid from water and carbon dioxide
-There are very limited and specific uses for these drugs
Potassium sparing diuretics → -Less effective than loop diuretics, but do not cause hypokalemia
-Able to produce diuresis without adversely affecting blood potassium levels
-Normally, sodium and potassium are exchanged in the distal tubule
-Potassium sparing diuretics block this exchange
Spironolactone (Aldactone) → (POTASSIUM SPARING DIURETIC)
S/E: Dehydration, Dizziness, HYPERKALEMIA
Diet low in potassium since we are sparing potassium. Do not use salt substitues b/c they are made of pure potassium. We do not want to cause hyperkalemia.
Hydrochlorothiazide (HCTZ) → (THIAZIDE DIURETIC)
S/E: Generally minor and rarely cause d/c of therapy, Dehydration, Hypotension, Need to check electrolytes for:
