On re-examination, Mr Thomas appears more lucid, but is still quiet and withdrawn.

He displays occasional episodes of irritability, but no wandering or other potentially dangerous behaviours have been reported by Mrs Thomas or care staff.  He is eating small amounts of food and taking liquids orally with assistance, to supplement the subcutaneous fluids.  He is less agitated now that the IV line is not constantly connected.

As Mr Thomas is more responsive at this examination, you decide to administer the cognitive screening tests.

He scores: 20/39 on KICA and 17/30 on MMSE, indicating a moderately impaired cognitive state.
