Hello! Thank you for your question.
When an EMR is providing medical care to a patient it can be stressful, whether or not they no what they are doing or they don't know what they are doing. Yes, if the EMR doesn't know what he or she is doing, it can be stressful. Even if the EMR has been doing their job for 10 years, it can still be very stressful, due to the atmosphere, the cituation, or even because the patient simply is not listening to the EMR.
I hope this helped you! Anymore questions? Just ask.
