Flashcard# 1.CV. Digoxin

For which heart conditions is digoxin primarily prescribed?

Congestive heart failure and atrial fibrillation.

Flashcard# 2.CV. Digoxin

How does digoxin help patients with atrial fibrillation?

It slows the heart rate by reducing the conduction rate of electrical impulses through the atrioventricular (AV) node.

Flashcard# 3.CV. Digoxin

What is one of the classic signs of digoxin toxicity in the eyes?

Yellow or greenish visual halos.

Flashcard# 4.CV. Digoxin

Which gastrointestinal symptoms can indicate digoxin toxicity?

Nausea, vomiting, and loss of appetite.

Flashcard# 5.CV. Digoxin

Why might a patient on digoxin experience confusion or delirium?

These are potential central nervous system effects of digoxin toxicity.

Flashcard# 6.CV. Digoxin

Why is it important to monitor potassium levels in patients on digoxin?

Hypokalemia increases the risk of digoxin toxicity.

Flashcard# 7.CV. Digoxin

Why should patients with ventricular fibrillation avoid taking digoxin?

Digoxin can exacerbate ventricular fibrillation, making it more difficult to treat.

Flashcard# 8.CV. Digoxin

Which diuretics, when taken with digoxin, may increase the risk of toxicity?

Loop and thiazide diuretics, as they can cause potassium loss.

Flashcard# 9.CV. Digoxin

Before administering digoxin, what vital sign should the nurse check?

Heart rate

10.

Flashcard# 10.CV. Digoxin

What is the generally accepted lower limit for heart rate, below which a nurse might withhold a digoxin dose and notify the physician?

Generally, 60 beats per minute, but this may vary based on specific patient parameters and physician orders.

11.

Flashcard# 11.CV. Digoxin

When monitoring a patient on digoxin, which lab values should be routinely checked?

Serum digoxin, potassium, magnesium, and renal function tests.

12.

Flashcard# 12.CV. Digoxin

How should a nurse instruct a patient on how to take their pulse before administering digoxin at home?

Use two fingers (not the thumb) to press lightly on the inside of the wrist below the thumb. Count the beats for a full minute.

13.

Flashcard# 13.CV. Digoxin

Why is it important for patients to take digoxin at the same time each day?

To maintain consistent therapeutic blood levels.

14.

Flashcard# 14.CV. Digoxin

What should the nurse advise regarding an accidentally missed dose of digoxin?

Take the missed dose as soon as remembered unless it's almost time for the next dose. Never double up on doses.

15.

Flashcard# 15.CV. Digoxin

What kind of diet may benefit patients taking digoxin?

A diet rich in potassium, unless otherwise contraindicated.

16.

Flashcard# 16.CV. Digoxin

How should digoxin be stored?

In its original container, away from light and moisture, and out of the reach of children.

17.

Flashcard# 17.CV. Digoxin

If a patient complains of nausea while on digoxin, what might be the initial intervention?

Check the patient's latest serum digoxin level to rule out toxicity.

18.

Flashcard# 18.CV. Digoxin

What should a nurse advise if a patient experiences visual disturbances while on digoxin?

Notify the healthcare provider immediately as this could be a sign of toxicity.

19.

Flashcard# 19.CV. Digoxin

Why is consistent monitoring of renal function crucial in patients on digoxin?

Digoxin is primarily excreted unchanged by the kidneys; reduced renal function can increase the risk of toxicity.

20.

Flashcard# 20.CV. Digoxin

Which over-the-counter medication should patients be cautioned about taking without doctor consultation due to potential interactions with digoxin?

Antacids, as they can interfere with digoxin absorption.
