Working as an NP is different in a number of ways, depending on your specialty. In primary care (FNP, PedsNP) you are frequently seeing patients in a clinic just like a doctor, where the focus is identifying and treating illness and prescibing meds. Your nursing knowledge comes with the additional health prevention, education, and encouragement in the patient being in control of treatment that an NP provides. In hospitals, you would also see patients working toward a diagnosis and medication management issues. Your holistic approach is what nursing brings to the table. Your nursing assessment skills are focused on diagnosis and medication/treatment in a different way that a nurse following patients on the floor, or seeing patients before the MD at a clinic would do. The additional training emphasizes the assessment, diagnosis and medication management of patients, while incorporating holistic approaches to care.
There is no typical day, as there is no typical NP setting (as there isn't a real typical day for MDs). Clinic NPs see patients every 15-20 minutes like a doctor in a clinic would. Inpatient NPs do rounds on their patients like a doc, would have a clinic schedule as well perhaps, and may assist in surgeries if they are Cardiothoracic or other specialized NPs. There are probably more NPs working in clinics than hospitals but this has been changing recently, as NP hospitalist skills become more widely accepted and utlilized and with the cut in resident hours. NPs have been increasingly hired as hospitalists to see patients.
I work both intpatient and outpatient, seeing inpatients in the morning, outpatients in clinic in the afternoons. Plus, there are NPs that also do research trials and other things that are part of their job. The field is what you develop. I wrote and developed my job description and practice independently with an MD backup if I need to consult on a case (which everyone, even MDs, have).
Hope this helps. Please try to e-mail, shadow or talk to as many NPs as you can to get their differing perspectives. When I went into this, everyone I e-mailed was happy to give my their insight.
