Details: Case study
You are a Registered Nurse working in the emergency department caring for Zach Forbes who is 15 years of age.
Medical history
Zach visited his local doctor after experiencing increased appetite and excessive thirst. He has been unusually tired
when playing cricket and hasn’t been able to perform at his best. He has lost 10 kilograms of weight over a two week
period and has been frequently urinating at night. The doctor suspected type 1 diabetes and tested his urine, which
was positive for glucose and ketones. A random capillary blood glucose level was 25.0mmol/L and blood ketone level
was 1.5mmol/L. Zach was advised to attend the hospital emergency department immediately.
Social history
Zach lives with his mother (Susan), father (John) and 10 year old brother (Jacob). He is in year 10 at high school
and works at McDonalds on a casual basis. Zach plays cricket on the weekends and trains two days during the week.
Emergency department review
Two hours after review by the local doctor, Zach’s capillary blood glucose level (BGL) was 26.0mmol/L and blood
ketone level was 1.6mmol/L. Other vital signs were within normal limits. After review by the endocrinologist, Zach
was given a provisional diagnosis of type 1 diabetes based on his symptoms and family history of autoimmune disease
(His mother has hyperthyroidism, Graves’ disease). His blood test confirmed that he did not have ketoacidosis.
Treatment plan
Zach was prescribed subcutaneous insulin; Aspart (NovoRapid) Flexpen 8 units TDS and Glargine (Lantus) Solostar
24 units nocte. He was referred to the diabetes service for inpatient review and ongoing care.
