What is a key consideration for a nurse when a patient starts corticosteroid therapy?

When a patient begins corticosteroid therapy, one of the primary concerns is the altered immune response that can occur as a result of these medications. Corticosteroids, such as prednisone, are known to suppress the immune system, which can increase the risk of infections and hinder the body's ability to respond to stressors. This immunosuppressive effect is particularly important to monitor in patients, as it may lead to complications in wound healing or an increased susceptibility to opportunistic infections.

Other considerations like gastrointestinal upset, increased insomnia, and the risk of dehydration may also be relevant during corticosteroid therapy, but they are not as critical as the impact on the immune system. Altered immune response is a significant aspect because it requires vigilant assessment and potentially adjustments in therapy to ensure the patient's safety and well-being.
