Hello Sathithya!

You most probably can! As because you have a nursing background only. After a BSc in critical care technology, you can go try for enrolling in BSc Nursing (Post Basic). If possible obtain a certificate in General Nursing and Midwifery (GNM) and register yourself in Registered Nurses and Registered Midwives (RNRM).

You can work as a critical care nurse after this and also as Chief Nursing Officer, Rehabilitation Specialist, Nursing Manager, Paramedic Nurse, Community Health Specialist and Nursing Supervisor

Hope this answer is helpful:)
