Using the Threat Probability Task to Assess Anxiety and Fear During Uncertain and Certain Threat
Published on: September 12, 2014
Abstract:
Last week I was working an evening shift when one of my clients had a serious unexpected incident. The client's family was present at the time and asked many questions and took notes. I felt I was being watched and judged. I was unsure about what information I should or could provide the family, but remembered someone once saying that it is better to say nothing in this type of situation. However, I felt it was important that I keep the family informed and offer empathy and care. Because I was unsure of what to do in this situation, I contacted an RNABC nursing practice consultant and reviewed our hospital policies and procedures. I know I did the right thing by keeping the family informed.
