Quick answer Clarify the 30-mg every-6-hour order.
Why this is correct The ketorolac label reduces both the individual and daily dose for adults 65 years or older, renally impaired clients, and clients under 50 kg. Increasing dose or frequency raises serious adverse-event risk without improving efficacy.
Easy analogy or mental picture A slower exit and greater sensitivity require a smaller load, not a bigger one.
Memory hook Age 65 or renal impairment: 15 mg q6h, maximum 60 mg/day.
NCLEX decision rule Apply the most restrictive age, weight, and renal rule before administration and count total ketorolac duration across routes.
Why the other choices are wrong Higher or more frequent dosing increases renal, gastrointestinal, and bleeding risk; ketorolac therapy is not indefinite.
