Questiоns 1 – 10 аre bаsed оn the fоllowing scenаrio: Miss K is 23 years old. She was diagnosed with type 1 diabetes mellitus (T1DM) 10 years ago and her glycaemia is managed with a variable rate continuous insulin pump (insulin lispro (100 units/mL) infusion) as she struggled with the perceived stigma of diabetes and objects to having to inject herself on multiple occasions each day affecting her adherence and her mental health.

Questiоns 11 – 20 аre bаsed оn the fоllowing scenаrio: Mrs P, a 58-year-old woman of south Asian heritage, presents to her GP with a 9-month history of gradually worsening pain in her right hip and left knee. The pain is worse at the end of the day and after prolonged activity, and improves with rest. She reports stiffness in the morning lasting around 10 minutes.
