Study Notes
Atrial Fibrillation Treatment
- Quinidine, Digoxin, or Amiodarone may be administered to a patient diagnosed with atrial fibrillation.
QT Prolongation Risk
- Amiodarone, Quinidine, and other medications can put patients at risk for QT prolongation.
Thrombi Dissolution
- Alteplase promotes lysis of fibrin and dissolution of thrombi.
Heparin Antidote
- Protamine sulfate is the antidote for heparin overdose or bleeding.
Low-Molecular-Weight Heparin Characteristics
- Enoxaparin, a low-molecular-weight heparin, has a longer half-life than heparin.
Anticoagulant Administration
- Warfarin is an oral anticoagulant, whereas heparin and enoxaparin are injectable anticoagulants.
Warfarin Antidote
- Vitamin K is the antidote for warfarin overdose or bleeding.
Enoxaparin Administration
