Airbags, Catalytic Converters and Cars: What Thieves Targeted Across Montgomery County

Digoxin, watch the heart and the potassium.

Digoxin increases cardiac contractility, meaning the strength of the heart's contraction while slowing electrical conduction through AV or atrioventricular node Digoxin has a narrow therapeutic index, meaning the difference between a therapeutic dose and a toxic dose can be relatively small.

Before administering digoxin, assess the apical pulse for one full minute.

For adults, it can commonly test the nursing rules to hold digoxin and notify the provider if the pulse is below 60 beats per minute, although the patient's prescribed parameters always take priority.

Important lab values include the serum, digoxin level, potassium, magnesium, and renal function.

Classic signs of digoxin toxicity include nausea, vomiting, loss of appetite, fatigue, confusion, and bradycardia, dysrhythmias, and visual disturbances such as blurred or yellow-green vision.

Here's an important exam connection.

Hypokalemia meaning low potassium can increase the risk of digoxin toxicity.

Severe, life-threatening toxicity may be treated with digoxin immune fab, an antibody fragment that binds circulating digoxin.

An exam trap that you may encounter is digoxin plus nausea plus an unusually slow pulse should make you think toxicity, not simply an upset stomach.
