Diuretics Flashcards
What is the primary action of diuretics in the treatment of hypertension?
Diuretics help reduce blood pressure by promoting the excretion of sodium and water, leading to decreased blood volume.
Which class of diuretics is commonly used as a first-line treatment for hypertension?
Thiazide diuretics.
Name a commonly used thiazide diuretic.
Hydrochlorothiazide.
True or False: Loop diuretics are more potent than thiazide diuretics.
True.
What is a common loop diuretic used for hypertension?
Furosemide.
Fill in the blank: Potassium-sparing diuretics help retain ______ while promoting diuresis.
potassium.
What is a potential adverse effect of thiazide diuretics?
Hypokalemia (low potassium levels).
List one contraindication for using loop diuretics.
Anuria (lack of urine production).
Which diuretic can cause hyperkalemia as a side effect?
Potassium-sparing diuretics.
True or False: Thiazide diuretics can increase blood glucose levels.
True.
What nursing education should be provided regarding diuretic therapy?
Patients should be educated about the importance of monitoring blood pressure and electrolyte levels.
Which electrolyte imbalances are most commonly associated with diuretic use?
Hypokalemia and hyperkalemia.
What is the mechanism of action of potassium-sparing diuretics?
They inhibit sodium reabsorption in the renal tubules while conserving potassium.
Name one adverse effect associated with loop diuretics.
Dehydration.
Multiple choice: Which of the following is NOT a diuretic? A) Hydrochlorothiazide B) Furosemide C) Lisinopril D) Spironolactone
C) Lisinopril.
What should patients taking diuretics be advised to monitor regularly?
Their weight and signs of dehydration.
True or False: Diuretics can be used in combination with other antihypertensive medications.
True.
Which diuretic is often used for patients with heart failure?
Loop diuretics.
Fill in the blank: Thiazide diuretics are most effective when used for ______ hypertension.
mild to moderate.
What is the role of diuretics in managing edema?
They reduce fluid retention by increasing urine output.
Name a potassium-sparing diuretic.
Spironolactone.
What is a common side effect of potassium-sparing diuretics?
Gynecomastia (breast tissue growth in males).
True or False: Patients on diuretics should limit their fluid intake.
False; they should maintain adequate hydration unless otherwise directed.
What is the significance of monitoring renal function in patients taking diuretics?
To prevent potential kidney damage and adjust dosages as needed.
What dietary recommendation is often given to patients taking thiazide diuretics?
Increase potassium-rich foods to prevent hypokalemia.
Multiple choice: Which of the following diuretics is primarily used for its potassium-sparing effects? A) Hydrochlorothiazide B) Furosemide C) Spironolactone D) Bumetanide
C) Spironolactone.
