A patient has 2+ pitting edema of the lower extremities
bilaterally. Auscultation of the lungs reveals crackles
bilaterally, and the serum potassium level is 6 mEq/L.
Which diuretic agent ordered by the prescriber should the
nurse question?
a.Bumetanide (Bumex)
b.Furosemide (Lasix)
c.Spironolactone (Aldactone)
d.Hydrochlorothiazide (HydroDIURIL) - Answer-
c.Spironolactone (Aldactone)
Spironolactone is a non-potassium-wasting diuretic;
therefore, if the patient has a serum potassium level of 6
mEq/L, indicating hyperkalemia, an order for this drug
should be questioned. Bumetanide, furosemide, and
hydrochlorothiazide are potassium-wasting diuretics and

would be appropriate to administer in a patient with
hyperkalemia.
A nurse preparing to administer morning medications
notes that a patient with a history of hypertension has
been prescribed the angiotensin-converting enzyme (ACE)
inhibitor captopril (Capoten) concurrently with
spironolactone (Aldactone). Morning laboratory results
reveal a serum sodium level of 144 mg/dL, a serum
potassium level of 5.1 mEq/L, and a blood glucose level of
128 mg/dL. Which intervention is appropriate?
a.Administer the medications as ordered.
b.Ask the patient about the use of salt substitutes.
c.Contact the provider to report the laboratory values.
d.Request an order for furosemide (Lasix). - Answer-
c.Contact the provider to report the laboratory values.
Spironolactone should not be administered with ACE
inhibitors, which can also elevate potassium levels.
Because the potassium level is elevated, the nurse should
not administer the medication and should obtain
clarification of the order. There is no need to repeat the
potassium level test that was just done this morning.

Requesting an order for furosemide is appropriate only
after the provider has been notified of the laboratory
values.
A patient with hypertension is taking furosemide (Lasix) for
congestive heart failure. The prescriber orders digoxin to
help increase cardiac output. What other medication will
the nurse expect to be ordered for this patient?
a.Bumetanide (Bumex)
b.Chlorothiazide (Diuril)
c.Hydrochlorothiazide (HydroDIURIL)
d.Spironolactone (Aldactone) - Answer-d.Spironolactone
(Aldactone)
Spironolactone is used in conjunction with furosemide
because of its potassium-sparing effects. Furosemide can
contribute to hypokalemia, which can increase the risk of
fatal dysrhythmias, especially with digoxin administration.
The other diuretics listed are all potassium-wasting
diuretics.

minute, intercostal retractions, and frothy, pink sputum.
The nurse caring for this patient will expect to administer
which drug?
a.Furosemide (Lasix)
b.Hydrochlorothiazide (HydroDIURIL)
c.Mannitol (Osmitrol)
d.Spironolactone (Aldactone) - Answer-a.Furosemide
(Lasix)
Furosemide, a potent diuretic, is used when rapid or
massive mobilization of fluids is needed. This patient
shows severe signs of congestive heart failure with
respiratory distress and pulmonary edema and needs
immediate mobilization of fluid. Hydrochlorothiazide and
spironolactone are not indicated for pulmonary edema,
because their diuretic effects are less rapid. Mannitol is
indicated for patients with increased intracranial pressure
and must be discontinued immediately if signs of
pulmonary congestion or heart failure occur.
A patient who is taking digoxin is admitted to the hospital
for treatment of congestive heart failure. The prescriber
has ordered furosemide (Lasix). The nurse notes an
