After speaking with a lot of school mates who've taken the NCLEX recently (with in the last 6 months or so) they have all stated to our school powers that be that the majority of the meds on their test were meds you see advertised on TV! Nexium, Plavix, Lunesta all the ED meds, the new diabetes meds, psych meds..those types that are advertised on tv.
Our instructors seem to think the reasoning is, if the general public knows about these meds from watching tv, then prospective nurses should too.
Since we are graduating in 6 months, our teachers have all given us the advice of paying attention to the meds on tv (that is in addition to knowing the common meds). Hope that helps.
