    Loop diuretics
  2. Abbreviation for the term that describes an index of how well the kidneys are functioning as filters
    GFR
  3. A general term for drugs that accelerate the rate of urine formation
    Diuretics
  4. The main structural unit of the kidney
    nephron
  5. A term for diuretics that cause the body to lose potassium
    Kaliuretic diuretics
  6. Diuretics that result in the diuresis of sodium and water and the retention of potassium; spironolactone is an example
    Potassium-sparing diuretic
  7. Diuretics that act on the distal convoluted tubule, where they inhibit sodium and water resorption; HCTZ is an example
    Thiazides
  8. Abbreviation for a class of diuretics that inhibit the enzyme carbonic anhydrase; acetazolamide is an example
    CAIs
  9. Drugs that induce diuresis by increasing the osmotic pressure of the glomerular filtrate, which results in a rapid diuresis; mannitol is an example
    Osmotic diuretics
  10. An abnormal intraperitoneal accumulation of fluid
    ascites
  11. Which of the following are indications for the use of diuretics? Select all that apply.
    a. to increase urine output
    b. to reduce uric acid levels
    c. to treat hypertension
    d. to treat open-angle glaucoma
    e. to treat edema associated with heart failure
    • a. to increase urine output
    • c. to treat hypertension
    • d. to treat open-angle glaucoma
    • e. to treat edema associated with heart failure
  12. When providing patient teaching to a patient who is taking a potassium-sparing diuretic such as spironolactone (Aldactone), the nurse should include which dietary guidelines?
    A. There are no dietary restrictions with this medication
    B. The patient should drink 1 to 2 L of fluid per day
    C. The patient should consume foods high in potassium, such as bananas and orange juice
    D. The patient should avoid foods high in potassium
    D. the patient should avoid foods high in potassium
    (this multiple choice question has been scrambled)

    B. Nausea, vomiting, and anorexia
    C. Diarrhea and abdominal pain
    D. Orthostatic hypotension
    A. Muscle weakness and lethargy
    (this multiple choice question has been scrambled)
  15. A patient with severe heart failure has been started on therapy with a CAI, but the nurse mentions that this medication may be stopped in a few days. Which of the following is the reason for this short treatment?
    A. CAIs are not the first choice for treatment of heart failure
    B. CAIs lose their diuretic effect in 2 to 4 days because metabolic acidosis develops
    C. Allergic reactions to the CAIs are common
    D. It is expected that the CAIs will dramatically reduce the fluid overload related to the heart failure
    B. CAIs lose their diuretic effect in 2 to 4 days because metabolic acidosis develops
    (this multiple choice question has been scrambled)
