Check your pulse before you take your digoxin. If your pulse is under 60 beats per minute, wait 5 minutes. Then check your pulse again. If it’s still under 60, call your healthcare provider.
What should be assessed before administering digoxin?
A nurse should assess the apical pulse for a full minute before administering digoxin due to its positive inotropic action (it increases contractility, stroke volume, and, thus, cardiac output), negative chronotropic action (it decreases heart rate), and negative dromotropic action (it decreases electrical conduction …
Why is pulse rate checked before administering digoxin?
Due to the risk for digoxin toxicity, the clinical use of digoxin has decreased and alternative, safer medications are being used. Apical pulse should be taken for a full minute before administration of this medication.
What do I need to know before giving digoxin IV?
Assessment
- Monitor apical pulse for 1 full min before administering. …
- Pedi: Heart rate varies in children depending on age, ask health care professional to specify at what heart rates digoxin should be withheld.
- Monitor BP periodically in patients receiving IV digoxin.
Which is important to monitor in patients taking digoxin?
While taking digoxin you’ll also need to have regular blood tests to monitor your kidney function and the levels of salts (electrolytes), particularly potassium, in your blood.
How do you prepare digoxin?
Digoxin injection can be administered undiluted or diluted with a 4-fold or greater volume of 0.9% Sodium Chloride Injection, 0.18 % Sodium Chloride/4% Glucose Injection or 5% Glucose Injection. A 4-fold volume of diluent equates to adding one 2 ml ampoule of digoxin to 6 ml of injection solution.

What are the signs and symptoms of digoxin toxicity and how would the nurse assess for these symptoms?
These are symptoms of digitalis toxicity:
- Confusion.
- Irregular pulse.
- Loss of appetite.
- Nausea, vomiting, diarrhea.
- Fast heartbeat.
- Vision changes (unusual), including blind spots, blurred vision, changes in how colors look, or seeing spots.
When should digoxin levels be checked?
– When monitoring digoxin therapy, drug levels should be drawn when the patient is at steady-state (ie: 4-5 half lives have passed since the last dose change or since drug initiation). – When monitoring digoxin, blood levels should be drawn no sooner than 6 hours after the most recent dose.
What does digoxin do to pulse?
Digoxin lowers the heart rate by enhancing vagal tone, which leads to slowing of sinoatrial and atrioventricular nodal conduction and thereby a reduction in heart rate.
What pulse rate would indicate digoxin must not be given?
For management of atrial fibrillation the maintenance dose of digoxin can usually be determined by the ventricular rate at rest, which should not usually be allowed to fall persistently below 60 beats per minute.
What should the nurse assess on their patient prior to administering a cardiotonic medication?
Assess closely patient’s heart rate and blood pressure to identify cardiovascular changes that may warrant change in drug dose.
How do you monitor digoxin toxicity?
To determine the total body load of digoxin (in milligrams) for patients experiencing toxicity as a result of chronic ingestion of digoxin, one should multiply the serum digoxin level (in ng/mL) by the volume of distribution of digoxin (7.3 L/kg) by the patient’s ideal body weight (in kg) and divide by 1,000.
What are signs and symptoms of digoxin toxicity?
Some early warning signs of overdose are confusion, loss of appetite, nausea, vomiting, diarrhea, or vision problems. Other signs of overdose are changes in the rate or rhythm of the heartbeat (becoming irregular or slow), palpitations (feeling of pounding in the chest), or fainting.
Why do you need to check the electrolytes Before starting a patient on digoxin?
The electrolyte and renal status of each patient should be ascertained prior to initiating treatment and periodically thereafter. Hypokalemia or hypomagnesemia, for example, may promote the development of digoxin-induced arrhythmias, while impaired renal function may result in higher than anticipated serum drug levels.
How do you check digoxin levels?
How is a digoxin test performed? Your doctor will check your levels of digoxin by testing a sample of your blood. They’ll probably ask you to go to an outpatient clinical laboratory to give a blood sample. The healthcare provider at the lab will draw blood from your arm or hand with a needle.
What is digoxin test?
Definition. A digoxin test checks how much digoxin you have in your blood. Digoxin is a type of medicine called a cardiac glycoside. It is used to treat certain heart problems.
How do you administer digoxin orally?
For oral dosage form (tablets): Adults—Your doctor will give your first few doses intravenously (rapid digitalization) and then, you’ll be switched to oral tablets for maintenance therapy. A maintenance dose of 0.125 to 0.5 milligram (mg) once a day will be given depending on your body weight and medical condition.
How do you administer digoxin tablets?
Take this medication by mouth with or without food, usually once daily or as directed by your doctor. If you are using the liquid form of this medication, carefully measure the dose using the dropper provided by the manufacturer. Do not use a household spoon because you may not get the correct dose.
How do you administer digoxin to an infant?
Digoxin comes as a tablet or liquid. If using liquid, draw up the correct amount of medicine in the medicine dropper or a syringe. Give a small squirt of the medicine inside the cheek. To avoid choking, let your child swallow each squirt before giving more.
Does digoxin affect blood pressure?
Results: Diastolic blood pressure significantly decreased and systolic blood pressure significantly increased during overnight sleep in the digoxin phase compared to placebo. Digoxin had no effect on either systolic or diastolic blood pressure during daytime.
When should digoxin be withheld?
Withhold dose and notify health care professional if pulse rate is <,60 bpm in an adult, <,70 bpm in a child, or <,90 bpm in an infant. Notify health care professional promptly of any significant changes in rate, rhythm, or quality of pulse.
Does digoxin control rate or rhythm?
Although symptom relief is comparable with both methods, rhythm-control therapy confers increased exercise tolerance. Digoxin is one of the medications used to manage heart rate, which is considered controlled when the ventricular response is 60 to 80 bpm at rest and 90 to 115 bpm during moderate exercise.
What are nursing considerations for digoxin?
Nursing Considerations Across the Lifespan
Serum digoxin levels should be monitored, with a normal therapeutic range from 0.8 to 2 ng/mL. Serum potassium levels should also be closely monitored for patients on digoxin because hypokalemia increases the effect of digoxin and can result in digoxin toxicity.
What are the indications for digoxin?
Digoxin is indicated in the following conditions: 1) For the treatment of mild to moderate heart failure in adult patients. 2) To increase myocardial contraction in children diagnosed with heart failure. 3) To maintain control ventricular rate in adult patients diagnosed with chronic atrial fibrillation.
What are the signs and symptoms of digoxin toxicity and why are older adults at a higher risk?
Chronic digoxin toxicity frequently occurs in the elderly as a result of decreased clearance of digoxin, due to either declining renal function or drug-drug interactions. Nausea, malaise, and weakness are common findings in chronic digoxin toxicity.
What is the antidote to digoxin?
In the case of severe digoxin intoxication, an antidote digoxin immune Fab (Digibind) is available. Digibind binds and inactivates digoxin.
What are the contraindications of digoxin?
Digoxin is contraindicated in the following conditions[5]:
- Acute myocardial infarction.
- Hypersensitivity to the drug.
- Ventricular fibrillation.
- Myocarditis.
- Hypomagnesemia.
- Hypokalemia.
- Wolf-Parkinson-White syndrome.
What do you give for digoxin toxicity?
Digoxin-specific antibody antigen-binding fragments (DSFab), brand name Digibind or Digifab, are an effective antidote that directly binds digoxin. DSFab is indicated for life-threatening toxicity including: Ventricular arrhythmias.
Does digoxin cause hyperkalemia or hypokalemia?
Digoxin toxicity causes hyperkalemia, or high potassium. The sodium/potassium ATPase pump normally causes sodium to leave cells and potassium to enter cells. Blocking this mechanism results in higher serum potassium levels.
Why is calcium contraindicated in digoxin toxicity?
One therapy that is used in patients with hyperkalemia is the administration of calcium to directly antagonize the cardiac effects of potassium. However, intravenous calcium is actually contraindicated in patients experiencing digoxin toxicity due to the risk of serious arrhythmias.
What lab value indicates digoxin toxicity?
Therapeutic levels of digoxin are 0.8-2.0 ng/mL. The toxic level is >,2.4 ng/mL.
