For a week, keep a log of your critical communications. Note who was involved in the communication; the context or situation in which it occurred; the time of the day and day of the week; what the message was; effectiveness of the communication; and what could have been done to improve in your communication.
Note: we are nursing students, we have to do a presentation related to this. The team consists of 6 people. we have to talk about critical communication but related to nursing. Keep it simple and short.
