I just took the midcurricular HESI two days ago. It was hard.
1. Know how to prioritize your nursing diagnoses. If you have 5 patients, then which is most urgent?
2. Pharmacology - luckily, they stuck to the more commonly prescribed drugs. For the exit exam, I am planning on picking out the "TOP 5" for each system... respiratory, psych, etc...
3. Nutrition. There were a LOT of nutrition questions - maybe it just seemed that way because I wasn't prepared for it, but I really was overwhelmed by them. Of course some of them were integrated with pharm questions. Like what foods would you tell a patient to avoid if they were taking XXX?
4. Therapeutic communication - be honest, firm, and caring.
5. ALWAYS THINK ABOUT MASLOW'S HEIRARCHY OF NEEDS. There were a lot of questions I missed because I was more concerned with hospital policy than I was with the basic needs of the patient. These questions can be very tricky.
6. Basic assessment - obviously. Glasgow, DTRs, BP readings, pulses, etc... Diabetes and hypertension were biggies.
7. Know grains, micrograms, all the conversions for dosage calculations.
Hope this helps and good luck!!!
