Can you read the prescription, interpret it and
recognise the drug? Wrong drug can kill or be ineffective
Right drug

Right patient

Right dose

IV admin: a rapid bolus creates high blood levels IM admin: muscles are well supplied with blood
so this route provides quite quick uptake SC admin: minimal blood supply to the site so
slow uptake of the drug. Creates a depot of drug.
Doses that reach correct blood levels after SC administration may be toxic if administered by routes that have more rapid uptake
Right route

Right timeRedosing schedules must be accurate to avoid toxic accumulation of drug
or blood concentrations falling too far for intervals
