Patient Safety & Quality AssuranceQuestion 65 of 100
Which pair of medications is most likely to be involved in a look-alike/sound-alike selection error?
a.amoxicillin and metformin
b.predniSONE and predniSOLONE
c.lisinopril and warfarin
d.ibuprofen and cetirizine
Explanation
predniSONE and predniSOLONE differ by only a few letters near the end of a long shared stem, sit next to each other alphabetically, and are stocked in similar strengths, which is the classic recipe for a wrong-drug selection. The other pairs share neither spelling, sound nor shelf position, so a technician reaching for one is unlikely to grab the other.
