Final answer:
The correct instruction for a client with type 1 diabetes who has influenza is to increase the frequency of self-monitoring their blood glucose levels. It is essential to maintain insulin therapy and to seek medical advice before making any changes to their regimen. The option (A) is correct.
Step-by-step explanation:
For a client with type 1 diabetes mellitus who has influenza, they must increase the frequency of self-monitoring their blood glucose levels. Influenza can alter blood glucose levels due to changes in eating patterns, the stress of illness, and the potential for nausea and vomiting. It is vital for individuals with type 1 diabetes to closely monitor their blood glucose and maintain their insulin regimen to manage their condition appropriately.
Discontinuing insulin or adjusting the dose without medical advice can lead to serious complications. Clients should not reduce insulin doses unless instructed by a healthcare provider, even if they are unable to eat their usual amount. Instead, they should work with their healthcare team to manage their diabetes during illness. Therefore, option (A) is correct.
