Therapeutic dosing and monitoring of warfarin (Coumadin) Treatment with warfarin should be initiated with standard doses of 5–10 mg. The initial adjustment of the prothrombin time takes about 1 week, which usually results in a maintenance dosage of 5–7 mg/d. The prothrombin time (PT) should be increased to a level representing a reduction of prothrombin activity to 25% of normal and maintained there for long-term therapy. When the activity is less than 20%, the warfarin dosage should be r...

Generalities of Congestive Heart Failure correct answers -Common end point of many forms of heart disease -2% of population in USA; 300,000 deaths -Impaired function renders heart unable to maintain output sufficient for metabolic requirements of body or when it can only do it at elevated filling pressures -Diminished cardiac output (forward failure) or accumulation of blood in venous system (backward failure) or both Initially adaptive compensatory mechanisms for congestive heart failure ...

What does the SA node initiate - - P wave (if none, SA not responsible for electrical conduction) (atrial depolarization) What does the QRS complex represent? - ventricular depolarization (vent contraction) (none=no pulse) (don't see atrial repolarization but it occurs, as it is not the strongest thing to occur) What does the U wave indicate? - indicates hypocalemia, not conductio issue it would be seen with electrolyes (digoxin) Is it normal to not see part of the Q, R, or S complex -...
