I would strongly recommend that you get a tutor. Spelling and sentence structure are very important when you are documenting. If you have problems spelling words commonly used in English, you will certainly have difficulty spelling medical terms. If you cannot spell the medical jargan correctly, others will not know what you are trying to say. Communication is huge when it comes to nursing. You have to be able to clearly communicate to others involved in patient care. Also, you will probably encounter trouble from other co-workers and staff if you cannot spell properly. The doctors, RN's etc. will treat you like crap because they will likely judge your intelligence by your grammar.
