What should a client with primary adrenal insufficiency understand about hydrocortisone therapy?

A client with primary adrenal insufficiency should understand the importance of monitoring their health closely, particularly for signs of adrenal crisis, which can occur during stress or illness. Low-grade fever can be an indication of infection or another stressor that could compromise the adrenal glands' ability to respond effectively. Therefore, it's crucial for the client to report any low-grade fever to their healthcare provider immediately so that appropriate measures can be taken. This precaution helps ensure timely intervention to prevent potential complications associated with inadequate adrenal hormone levels during stress situations.

Other options, while addressing various aspects of treatment and care, do not emphasize critical aspects of monitoring and reporting symptoms that could indicate a need for urgent medical assessment or adjustment in therapy.
