Exploring nursing roles: using physical assessment in the respiratory unit.

The role of the nurse continues to change, with the point where nursing stops and medicine begins becoming increasingly blurred. Arguably, the main driver for this change could be the recent reduction in junior doctors' working hours. However, modern nursing is ripe for innovation and nurses are taking on more and more tasks and skills that were traditionally part of the doctor's remit. One example is physical assessment, which has very little evidence to support its use in any setting. Analysis of the utilization of physical assessment in the respiratory unit indicates that although it could facilitate earlier recognition of peri-arrest symptoms, its usage highlights training and legal issues. Furthermore, this article will explore whether the continual adoption of tasks, such as physical assessment, constitute mere role extension, with nurses becoming physicians' assistants rather than advanced autonomous practitioners.
