Nurse Dwyer

Nurse Dwyer assisted Dr Sharma when he performed allergy tests on Percy Sugden at Weatherfield General in August 1991. Percy was undergoing the tests to determine the cause of a recent asthma attack. The nurse made a note of the extracts which Dr Sharma applied to Percy's arm and was also on hand when the doctor returned to deliver the results to Percy. While waiting for the doctor to return to Percy's bedside, Nurse Dwyer reminded Percy not to scratch his arm and told him he'd get a good conduct medal when he gave his assurance that he'd followed the instruction.

The results, as delivered by Dr Sharma, were that Percy was mildly allergic to grass pollen and extremely allergic to cats, thus revealing the origin of his asthma attack to be his landlady Winnie Dyson's pussy Fluffy.
