In which domain is 'Performing chest compressions' categorized?

'Performing chest compressions' is categorized in the psychomotor domain because this domain encompasses physical skills and the ability to perform motor functions. The psychomotor domain focuses on the development of manual or physical skills, which requires practice and coordination.

Chest compressions, an essential part of cardiopulmonary resuscitation (CPR), involve specific movements and techniques that are necessary to effectively provide mechanical support to a person whose heart has stopped beating. Mastering these skills requires hands-on practice and the ability to demonstrate the correct technique, which are key components of the psychomotor domain.

The other domains—affective, cognitive, and emotional—do not accurately capture the physical action involved in performing chest compressions. While these domains may relate to the emotional response to the situation or the understanding of why chest compressions are necessary, they do not address the actual physical execution of the skill itself. Thus, the psychomotor domain is the appropriate classification for 'performing chest compressions.'
