Application
The knowledge and skills specified in this unit are typically required by a person involved directly in the provision of out-of-hospital care in the ambulance environment. These workers must be able to apply a comprehensive knowledge of anatomy, physiology, pathophysiology and pharmacology to client assessment and care. The application of knowledge and skills described in this competency unit relate to functioning under supervision to plan and practise client assessment within relevant state/territory clinical practice guidelines. The unit provides a knowledge base required to formulate diagnostic reasoning and the application of client care treatments. This knowledge base also underpins successful application of ambulance care competency units in the HLT07 Health Training Package, including those for client care, access and egress. Successful assessment of the essential knowledge described in this competency unit (and its co-requisite) is required before undertaking supervised client assessment and delivery of care at the level of skill described. |
