chain of infection - ANS-infectious agent, reservoir, portal of exit, mode of transmission,

washing

Dose - ANS-How much of the medications is administered
Mechanism of Action - ANS-Certain responses expected in the body can also be

Side Effects - ANS-Negative effects or actions other than the desired actions
Contraindiciations - ANS-Situations where you wouldn't administer the medication
because it may do more harm than good. Preexisiting conditions commmonly result in a
