1. The nurse is preparing to administer the first dose of hydrochlorothiazide
(HydroDIURIL) 50 mg to a patient who has a blood pressure of 160/95 mm Hg. The
nurse notes that the patient had a urine output of 200 mL in the past 12 hours. The
nurse will perform which action?
a. Administer the medication as ordered.
b. Encourage the patient to drink more fluids.
c. Hold the medication and request an order for serum BUN and creatinine.
d. Request an order for serum electrolytes and administer the medication. -
ANSWER ANS: C
Thiazide diuretics are contraindicated in renal failure. This patient has oliguria and
should be evaluated for renal failure prior to administration of the diureticespecially in
the absence of known renal failure for this patient. Drinking more fluids will not
increase urine output in patients with renal failure.

2. The nurse is preparing to administer doses of hydrochlorothiazide (HydroDIURIL)
and digoxin (Lanoxin) to a patient who has heart failure. The patient reports having
blurred vision. The nurse notes a heart rate of 60 beats per minute and a blood
pressure of 140/78 mm Hg. Which action will the nurse take?
a. Administer the medications and request an order for serum electrolytes.
b. Give both medications and evaluate serum blood glucose frequently.
c. Hold the digoxin and notify the provider.
d. Hold the hydrochlorothiazide and notify the provider. - ANSWER ANS: C
When thiazide diuretics are taken with digoxin, patients are at risk of digoxin toxicity
because thiazides can cause hypokalemia. The patient has bradycardia and blurred
vision, which are both signs of digoxin toxicity. The nurse should hold the digoxin
and notify the provider. Serum electrolytes may be ordered, but the digoxin should
not be given.

3. The nurse is teaching a patient about taking hydrochlorothiazide. Which statement
by the patient indicates a need for further teaching?
a. I may need extra sodium and calcium while taking this drug.
b. I should eat plenty of fruits and vegetables while taking this medication.
c. I should take care when rising from a bed or chair when Im on this medication.
, d. I will take the medication in the morning to minimize certain side effects. -
ANSWER ANS: A
Patients do not need extra sodium or calcium while taking thiazide diuretics.
Thiazide diuretics can lead to hypokalemia, so patients should be counseled to eat
fruits and vegetables that are high in potassium. Patients can develop orthostatic
hypotension and should be counseled to rise from sitting or lying down slowly.
Taking the medication in the morning helps to prevent nocturia-induced insomnia.

4. The nurse is caring for a patient who is to begin receiving a thiazide diuretic to
treat heart failure. When performing a health history on this patient, the nurse will be
concerned about a history of which condition?
a. Asthma
b. Glaucoma
c. Gout
d. Hypertension - ANSWER ANS: C
Thiazides block uric acid secretion and elevated levels can contribute to gout.
Patients with a history of gout should take thiazide diuretics with caution; they may
need behavioral and/or pharmacologic changes to their gout treatment.

5. The nurse is caring for a patient who develops marked edema and a low urine
output as a result of heart failure. Which medication will the nurse expect the
provider to order for this patient?
a. Digoxin (Lanoxin)
b. Furosemide (Lasix)
c. Hydrochlorothiazide (HydroDIURIL)
d. Spironolactone (Aldactone) - ANSWER ANS: B
Furosemide is a loop diuretic and is given when the patients condition warrants
immediate removal of body fluid, as in heart failure. Digoxin improves cardiac
function but does not remove fluid quickly. The other diuretics may be used when
immediate fluid removal is not necessary.

6. The nurse is caring for a patient who is receiving furosemide (Lasix) and an
aminoglycoside antibiotic. The nurse will be most concerned if the patient reports
which symptom?
a. Dizziness
b. Dysuria
c. Nausea
d. Tinnitus - ANSWER ANS: D
