Good nurses are responsible. Nurses play a large role in the assessment of patients’ conditions and treatment of both serious and minor conditions.Nurses must responsibly carry out their duties at all times. They have to be able to keep track of and record minor changes in a patient’s health or behavior, because neglecting to notice something could end up having serious consequences. Nurses also must be responsible when it comes to their job demands and be flexible with their time. Nurses typically do not work regular set schedules and since emergencies can occur at any time, they are often required to work overtime, nights, weekends, and holidays.
