Term

Which is an expected outcome associated with administration of digoxin

 

Decreased heart Rate

 

Digoxin has a negative chronotropic effect (Decreased heart rate)

Definition
Term

The patient has a serum digoxin level drawn and it comes back 0.4 mg/ml

The nurse recognizes that this is

 

Below the therapeutic level

 

Therapeutic serum digoxin levels are 0.5 to 2 mg/ml

Definition
Term

A patient is taking digoxin 0.25 mg and furosemide (Lasix) 40 mg when the nurse enters the room the patient states "there are nice halos around the lights

 

Evaluate the patient for other symptoms of digoxin toxicity

 

Yellow and Green halos around objects is red flag symptom of digoxin toxicity

Definition
Term

The patient weighs 44 lbs and is to be digitalized. The digitalizing dose is to be 0.03 mg/kg in three divided doses.

 

0.2 mg

 

44 / 2.2 = 20 kg

0.03mg/kg x 20 = 0.6 mg

0.6mg /3 doses = 0.2 mg/dose

Definition
Term

Which are therapeutic effects of digoxin

 

A positive inotropic, negative chronotropic, and negative dromotropic

 

Digoxin increases cardiac contractility (positive inotropic effect) decreases heart rate (negative chronotropic effect) and decreases conductivity (negative dromotropic effect)

Definition
Term

Which effect would alert the nurse to suspect elderly digitails toxicity

 

Nausea and Vomitting

 

Early symptoms of digitalis toxicity include anorexia, nausea and vomitting (related to GI) fatigue, headache, depression, weakness
