Hi, there
I just took the Naplex too and I barely passed because I studied all wrong. I coached four of my friends on how to pass and they did significantly better than I did with just my information as a study guide (125+!). They found it "really easy" and I honestly wished I my friends that took the test before me break it down for me this way. Like I was generally upset with my friends that passed before me agreeing with my study guide for my other friends. So, this is just my "opinion" on how I would have spent much less time, and done much better. Remember n=4, so it could just be random luck.
So some mistakes I made:
a) You're not a doctor. You don't diagnose. Spending any time learning patho-physiology was a complete waste of time. The big ole 1000 page RX prep or apha or other books, WAY too much time reading useless info about the disease states. My friends and I had ZERO questions related to understanding the disease states. Not how it starts, why it gets worst, progression end stage.. etc...
b) Understanding patient charts and making conclusions was a complete waste of time. Yes, the test does present questions in "patient chart" format, but it's not interpretation. It's more like "of the 4 drugs on april 1st, which medication can be simplified into a combination (i.e. using a patient chart to ask a simple brand/generic)" or "drug on 4/1 is used to treat the patient's : select all disease that apply" and the diseases are all listed for you on patient chart (i.e. just a simple drug and indication match). Think of the patient chart as a list of information and NOT a case for you to practice clinical skills on.
Study differences:
a) Most DEFINITELY do calculations well. It's supposedly worth 33% of your grade (no clue where they got that number but it's the gist based on multiple official study guides). I think 1-2 hours reviewing mEq (5 questions), mOsm (2 questions), and mMols (2 questions), and TPN (calorie calculations) should satisfy these needs. This forum has a nice guide. you can find many other free calculation prep. 30 minutes or more on refreshing your dimensional analysis skills. Very little effort for a significant chunk of your test!
b) BRAND - GENERIC - INDICATION. I have the top 200 drugs community and health systems known by heart. That WASN'T enough. Half of the drugs on there I went "What the f*** is that?" Not that I forgot, but I literally have never seen it in my studying. Some I barely recalled from mentioning in my school or rotations, but I didn't take the time to learn them. So pull up your oncology and HIV notes. Those drugs aren't generally top 200 anywhere. Some drugs I recognized as the "lesser known" brand name. So when the drug cards list 2-4 brand names for the drug, KNOW them all! My list for my friends was in total 420 drugs. With that list, they only said there were 1 or 2 drugs they didn't recognize. Flash card them. Very effective, and time well spent.
c) LEARN ALL COMBOS: About 20 of my questions were combinations: Diabetes, hypertension, and lipids. I was particularly stumped with the niacin combos.
d) make a list of disease states by name and first line. Such as Addisons, Graves, and Cushing.
e) I got lucky and know enoxaparin very well due to one of my rotation. I had 7 questions on that and my friends said they all had 4-5 each at least. Exact dosage/regimen (not sure if this is considered calculations). You don't need to diagnose. Chart says "PE" or "DVT." If not, then it's prophylaxis dose. Know all of them. Know WHERE you can give it. Know ClCr adjustments.
f) Finally, side effect and drug drug interaction. It is an important part of your test. Hopefully over time you know the major ones. However, this is a massive amount of information to be "complete." You can spend a lifetime studying this and still miss stuff. So, for the most bang for your time, I'd focus on the A-E, and then spend left over time on this topic. Maybe your test will have more on this topic than others, but honestly, you can study this forever and forget just as much as you learn. For the sake of time, if you already know brand/generic/indication from B, learn CLASS adverse effects interactions.
Hope this helps. It would have helped me immensely.
