What condition should be emphasized when taking a medical history of a client prescribed corticosteroids?

When taking a medical history of a client prescribed corticosteroids, it is particularly important to emphasize infections. This is because corticosteroids can significantly suppress the immune system, making patients more vulnerable to infections. Patients on corticosteroids experience changes in immune function, which can lead to an increased risk of both opportunistic infections and reactivation of latent infections. Therefore, understanding the client's history regarding any previous infections and their current health status is crucial in managing their care effectively.

Other conditions such as diabetes, hypertension, and cardiovascular disease also have important considerations when prescribing corticosteroids, as these medications can exacerbate these conditions. However, the direct impact of corticosteroids on immune suppression and the heightened risk of infections is a more immediate concern that should be prioritized in the medical history assessment.
