As far as medications for the ICU- it's more of class systems of meds that you want to learn and how they will be functioning. Beta-blockers, Ace Inhibitors, diuretics, calcium channel blockers, know how morphine is beneficial, what meds are used for rates, others for pressures. Go over your rhythms, pathophysiology (CHF, Afib RVR, etc.). That is a good starting place. Good luck! It will be a great learning experience!
