Final answer:
The nurse should instruct the client with type 1 diabetes and acute bronchitis to continue taking insulin as prescribed.
Step-by-step explanation:
When instructing the client with type 1 diabetes mellitus and acute bronchitis, the nurse should include the following statement: 'Continue taking your insulin as prescribed.' This is because type 1 diabetes is a chronic autoimmune disorder in which the immune system attacks the insulin-secreting beta cells of the pancreas, resulting in a lack of insulin in the body. Insulin injections are critical for survival in type 1 diabetics, regardless of any other illnesses or conditions they may have.
