Back on the wards, some of Wales’s youngest nurses are dealing with all kinds of medical challenges that are thrown their way.

In Carmarthen, there’s no easing in for very newly qualified Caitlin, who has to learn fast in her first week in A&E. Across the ward, her friend and colleague, 22-year-old Mikey, battles to keep a patient with severe hypothermia alive.

On the Stroke Unit in Aberystwyth, a visit from Nelly the therapy dog lifts not just the patients’ spirits, but the nurses' too, while nurse Gina helps keep morale high on the ward with her funny banter.
