I suggest you read up on a neuro assessment, pay careful attention to changes in level of consciousness, know how to assess for glasgow coma scale (eye opening, verbal response, motor response). Look for level of reaction, i.e. alert, drowsy, unconscious etc.. Assess for language, i.e., clear, slurred, dysphasia, etc... Assess for muscle strength, i.e. equal bilat., strong, moves against gravity,purposeful movement, twitching, paralysis,etc... Assess pupils are they equal and reactive, dilated, fixed. I am sure that you will be given a orientation so just watch what the other nurses do, ask a lot of questions. Good luck with your new job.
