furosemide is a potassium-losing diuretic. Giving these together minimizes electrolyte imbalance
3. 3.ID: 526957047
Which laboratory value depicts a known side effect of furosemide (Lasix)?
A. Hyperchloremia
B. Hypernatremia
C. Hypokalemia Correct
D. Hypophosphatemia
Furosemide is a potent loop diuretic, resulting in the loss of potassium as well as water, sodium, and chloride
4. 4.ID: 526957044
A patient is admitted to the hospital with pneumonia and has a history of chronic renal insufficiency. Why does the physician order furosemide (Lasix) 40 mg twice a day?
A. Furosemide will not cause potassium loss.
B. Furosemide is effective in treating patients with pulmonary congestion.
C. Furosemide is effective in treating patients with renal insufficiency. Correct
D. Furosemide will increase PO2 levels.
Furosemide is effective in patients with creatinine clearance as low as 25 L/min (normal is 125 L/min)
5. 5.ID: 526956379
The nurse would question the use of mannitol for which patient?
A. A 67-year-old patient who ingested a poisonous substance
B. A 21-year-old patient with a head injury
C. A 47-year-old patient with anuria Correct
D. A 55-year-old patient who receives cisplatin to treat ovarian cancer
Mannitol is not metabolized but excreted unchanged by the kidneys. Potential water intoxication could occur if mannitol is given to a patient without urine output and thus renal function
6. 6.ID: 526957050
When preparing to administer furosemide (Lasix) intravenously to a patient with renal dysfunction, the nurse plans implementation based on knowledge that the medication should be administered no faster than which rate?
A. 2 mg/min
B. 4 mg/min Correct
C. 6 mg/min
D. 8 mg/min
Furosemide infusion rates should not exceed 4 mg/min in patients with renal dysfunction. Otherwise, furosemide may be administered at 20 mg/min, but that is not an option in this question.
7. 7.ID: 526957041
A patient asks about taking potassium supplements while taking spironolactone (Aldactone). What is the nurse's best response?
A. "You are correct about your concern. I will make sure that you get some right away."
B. "I will call your doctor and let him know of your concern."
C. "Potassium supplements are usually not necessary with this type of diuretic."
D. "You are on a diuretic that is potassium-sparing, so there is no need for extra potassium." Correct
Spironolactone is a potassium-sparing diuretic and thus the patient does not need potassium supplementation. Although it is true that potassium supplements are not necessary with this type of diuretic, providing the patient with an explanation of why the potassium is not needed is a better response.
8. 8.ID: 526957034
The nurse would expect to administer which diuretic to treat a patient diagnosed with primary hyperaldosteronism?
A. spironolactone (Aldactone) Correct
B. hydrochlorothiazide (HydroDIURIL)
C. acetazolamide (Diamox)
D. furosemide (Lasix)
Spironolactone is the direct antagonist for aldosterone.
9. 9.ID: 526956373
The nurse prepares to administer which diuretic to treat a patient with acute pulmonary edema?
A. spironolactone (Aldactone)
B. amiloride (Midamor)
C. triamterene (Dyrenium)
D. furosemide (Lasix) Correct
Furosemide is a potent, rapid-acting diuretic that would be the drug of choice to treat acute pulmonary edema. The other medications are not potent enough to cause the strong diuresis necessary to treat this acute situation
10. 10.ID: 526956376
When evaluating for therapeutic effects of mannitol, what does the nurse anticipate?
A. Decreased intracranial pressure Correct
B. Decreased excretion of therapeutic medications
C. Increased urine osmolality
D. Decreased serum osmolality
Mannitol is an osmotic diuretic that pulls fluid from extravascular spaces into the bloodstream to be excreted in urine. This will decrease intracranial pressure, increase excretion of medications, decrease urine osmolality, and increase serum osmolality.
11. 11.ID: 526956364
When assessing a patient taking triamterene (Dyrenium), the nurse would specifically monitor for which adverse effect?
A. Hypokalemia
B. Hypoglycemia
C. Hyperkalemia Correct
D. Hypernatremia
Triamterene is a potassium-sparing diuretic, and therefore hyperkalemia is a possible adverse effect
12. 12.ID: 526956369
When teaching a patient about signs and symptoms of hypokalemia, the nurse will instruct the patient to notify the health care provider if which occurs?
A. Diaphoresis
B. Leg cramps Correct
C. Constipation
D. Blurred vision
Leg cramps are a common clinical manifestation of hypokalemia. The other answers are incorrect.
13. 13.ID: 526957000
A patient taking spironolactone (Aldactone) requests assistance with dietary choices. The nurse would recommend which food choices? (Select all that apply.)
A. Lean meatCorrect
B. Bananas
C. Apples
D. Squash
<div>Spironolactone is a potassium-sparing diuretic that could potentially cause hyperkalemia. Bananas are high in potassium and should be avoided in patients taking spironolactone.</div>
Awarded 0.33 out of 1.0 possible points.
14. 14.ID: 526956387
Acetazolamide (Diamox) is used to treat which disorders? (Select all that apply.)
A. Edema associated with heart failureCorrect
B. Metabolic acidosis
C. High-altitude sickness
D. Open-angle glaucoma
<div>Acetazolamide causes excretion of bicarbonate, which would worsen metabolic acidosis. It is used to treat high-altitude sickness, edema secondary to heart failure, and open-angle glaucoma and rarely as an antiepileptic drug.</div>
15. 15.ID: 526956382
Potassium-sparing diuretics may cause which adverse reactions? (Select all that apply.)
A. HyperkalemiaCorrect
B. DizzinessCorrect
C. HeadacheCorrect
D. Hypermagnesemia
E. Muscle cramps
<div>Hyperkalemia, dizziness, and headache are common side effects associated with potassium-sparing diuretics.</div
