FUNDAMENTAL CONCEPT OF NURSING
For a patient prescribed hydrochlorothiazide ( HCTZ ), the nurse should closely monitor
which laboratory test value?
-
A. Sodium
B. Glucose
C. Calcium
D. Chloride
B. Glucose
-
Thiazide and thiazide-like diuretics are associated with adverse metabolic effects
of hyperglycemia; therefore, close monitoring of blood glucose levels are needed.
Other metabolic disturbances include hyperlipidemia and hyperuricemia.
The nurse is providing education to a patient prescribed spironolactone (Aldactone) and
furosemide (Lasix). What information does the nurse explain to the patient?
-
A. Using two drugs increases blood osmolality and the glomerular filtration rate.
B. This combination promotes diuresis but decreases the risk of low levels of
potassium.
C. The lowest dose of two different types of diuretics are more effective than a large
dose of one type.
D. This combination maintains water balance to protect against dehydration and
electrolyte imbalance.
B. This combination promotes diuresis but decreases the risk of low levels of
potassium.

,Spironolactone is a potassium-sparing diuretic; furosemide is a potassium-losing
diuretic. Giving these together minimizes potassium loss.
Which laboratory test result is a common adverse effect of furosemide (Lasix)?
-
A. Hypokalemia
B. Hypernatremia
C. Hyperchloremia
D. Hypophosphatemia
A. Hypokalemia
-
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.
Why does the health care provider prescribe furosemide (Lasix) 40 mg twice a day by
mouth for a patient with a history of renal insufficiency?
-
A. Furosemide is effective in treating patients with hypoaldosteronism.
B. Furosemide helps the kidney with reabsorption of sodium and water.
C. Furosemide has an antagonist effect to prevent respiratory alkalosis.
D. Furosemide is effective in treating patients with impaired kidney function.
D. Furosemide is effective in treating patients with impaired kidney function.
-
Furosemide effectiveness continues in impaired renal function. When creatinine
clearance decreases below 25 L/min (normal is 125 L/min), the loop diuretics can
still work.
When preparing to administer intravenous furosemide (Lasix) to a patient with renal
dysfunction, the nurse will administer the medication no faster than which rate?
-
A. 2 mg/min
B. 4 mg/min
C. 6 mg/min
D. 8 mg/min
B. 4 mg/min
-
Furosemide controlled infusion rate should not exceed at a rate of 4 mg/min in
patients with renal failure.
A patient asks the nurse about using potassium supplements while taking
spironolactone (Aldactone). What is the nurse's best response?

,-
A. "I will call your health care provider and discuss your concern."
B. "I would recommend that you take two multivitamins every day."
C. "This diuretic is potassium sparing, so there is no need for extra potassium."
D. "You will need to take potassium supplements for the medication to be effective."
C. "This diuretic is potassium sparing, so there is no need for extra potassium."
-
Spironolactone is a potassium-sparing diuretic, and thus the patient does not need
potassium supplementation. Intake of excess potassium may lead to
hyperkalemia.
To treat a patient diagnosed with primary hyperaldosteronism, the nurse would expect
to administer which diuretic?
-
A. Furosemide (Lasix)
B. Acetazolamide (Diamox)
C. Spironolactone (Aldactone)
D. Hydrochlorothiazide (HCTZ)
C. Spironolactone (Aldactone)
-
Spironolactone is the direct antagonist for aldosterone
To treat a patient with pulmonary edema, the nurse prepares to administer which
diuretic to this patient?
-
A. Furosemide (Lasix)
B. Amiloride (Midamor)
C. Triamterene (Dyrenium)
D. Spironolactone (Aldactone)
A. Furosemide (Lasix)
-
Furosemide is a potent, rapid-acting diuretic that would be the drug of choice to
treat pulmonary edema. The other medications are not potent enough to cause the
diuresis necessary to treat this condition.
When teaching a patient about symptoms of hypokalemia, the nurse will instruct the
patient to notify the health care provider if which symptom occurs?
-
A. Diaphoresis
B. Constipation
3|Page
, C. Blurred vision
D. Muscle weakness
D. Muscle weakness
-
Muscle weakness is a common symptom of hypokalemia. The other answers are
incorrect.
A patient prescribed spironolactone (Aldactone) asks the nurse to assist with food
choices that are low in potassium. The nurse would recommend which food choices?
(Select all that apply.)
-
A. Apples
B. Bananas
C. Pineapple
D. Lean meat
E. Winter squash
A. Apples
C. Pineapple
D. Lean meat
-
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
Potassium-sparing diuretics may cause which common adverse reactions? (Select all
that apply.)
-
A. Dizziness
B. Headache
C. Hyperkalemia
D. Mental confusion
E. Muscle weakness
A. Dizziness
B. Headache
C. Hyperkalemia
-
Hyperkalemia, dizziness, and headache are common adverse effects associated
with potassium-sparing diuretics.
The nurse is providing education to a patient on why spironolactone (Aldactone) and
furosemide (Lasix) are prescribed together. What information does the nurse provide to
