2. The nurse is preparing to administer doses of hydrochlorothiazide (HydroDIURIL) and digoxin

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. - CORRECT 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. - CORRECT 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.
