Chapter 28: Diuretic Drugs Test, Furosemide, Pharmacology for Nurses: Practical Applications

The key terms in this Pharmacology course include Diuretic Drugs, Furosemide, Hypokalemia, Pharmacology for Nurses: Practical Applications


Which laboratory test result is a common adverse effect of furosemide?

Hypokalemia

Hypophosphatemia

Hypernatremia

Hyperchloremia

Furosemide is a potent loop diuretic, and the most common adverse effect of loop diuretics is electrolyte imbalances. This results in major electrolyte losses of potassium and sodium and, to a lesser extent, calcium.


To treat a patient diagnosed with primary hyperaldosteronism, the nurse would expect to administer which diuretic?

Spironolactone

Hydrochlorothiazide

Acetazolamide

Furosemide

Spironolactone is the direct antagonist for aldosterone.


A patient prescribed spironolactone asks the nurse to assist with food choices that are low in potassium. The nurse would recommend which food choices? (Select all that apply.)

Lean meat

Pineapple

Winter squash

Bananas

Apples

Spironolactone is a potassium-sparing diuretic that could potentially cause hyperkalemia. Bananas and winter (not summer) squash are high in potassium and should be avoided in patients taking spironolactone.


Acetazolamide is used to treat which conditions? (Select all that apply.)

Edema associated with heart failure

High-altitude sickness

Cardiac dysrhythmias

Open-angle glaucoma

Dry eye syndrome

Acetazolamide causes excretion of bicarbonate, which would worsen metabolic acidosis. It is used to treat high-altitude sickness, edema secondary to heart failure, open-angle glaucoma, and rarely as an antiepileptic drug. It is not used for treatment of dry eye syndrome or cardiac dysrhythmias.


Potassium-sparing diuretics may cause which common adverse reactions? (Select all that apply.)

Headache

Muscle weakness

Mental confusion

Hyperkalemia

Dizziness

Hyperkalemia, dizziness, and headache are common adverse effects associated with potassium-sparing diuretics.


When teaching a patient about symptoms of hypokalemia, the nurse will instruct the patient to notify the health care provider if which symptom occurs?

Diaphoresis

Blurred vision

Constipation

Muscle weakness

Muscle weakness is a common symptom of hypokalemia. The other answers are incorrect.


When assessing a patient taking triamterene, the nurse would monitor for which possible adverse effect?

Hypoglycemia

Hypernatremia

Hyperkalemia

Hypokalemia

Triamterene is a potassium-sparing diuretic, and therefore hyperkalemia is a possible adverse effect.
