How does the nurse make sure dosage and administration is correct?
indication - pain vs inflammation
route of administration
safety of intravenous agents

What measures can a nurse take to reduce adverse events wrt drugs?
identifying high-risk patients, ensuring proper administration, teaching patients to avoid activities that might precipitate and adverse event
What do you have to know about the drugs to minimize adverse EFFECTS?
the major adverse effects the drug can produce
when the reactions are likely to occur
what the early signs are of an adverse reaction
interventions that can minimize discomfort and harm
How can a nurse minimize adverse INTERACTIONS
taking a through drug history, advising patient to avoid OTC drugs that can interact w prescribed
