Final answer:
Stopping hydrocortisone abruptly can lead to circulatory collapse as a withdrawal effect, due to the body's sudden lack of external glucocorticoids, which can cause an adrenal crisis.
Step-by-step explanation:
When hydrocortisone use is discontinued abruptly, the nurse must assess for the side effect of circulatory collapse. Hydrocortisone is a synthetic form of cortisol, a hormone essential for regulating metabolism, immune response, and stress. Its prolonged external provision can suppress the body's natural adrenal functions. Suddenly stopping this medication can cause the body to experience symptoms akin to those of Addison's disease due to the abrupt withdrawal of external glucocorticoids.
This may manifest as an adrenal crisis characterized by weakness, nausea, hypotension, severe abdominal pain, and, in severe cases, circulatory collapse due to the rapid decrease in cortisol levels. This collapse is potentially life-threatening and requires immediate medical attention. Gradual tapering off hydrocortisone allows the adrenal glands time to resume their normal production of cortisol and minimise the risk of withdrawal symptoms.
