diureticespecially in the absence of known renal failure for this patient.

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.


✓~ 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.


✓~ 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.

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


✓~ 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.
