A nurse is teaching a patient about taking high doses of oral glucocorticoids for an extended period to treat rheumatoid arthritis.Which of the following instructions should the nurse include in the teaching?

Choice A rationaleChecking blood glucose levels for hypoglycemia once yearly is insufficient for a patient taking high doses of oral glucocorticoids for an extended period. Glucocorticoids can cause hyperglycemia by increasing gluconeogenesis and insulin resistance. Therefore, blood glucose monitoring should be more frequent, especially when initiating or adjusting the dosage. Normal fasting blood glucose levels are typically 70-99 mg/dL.Choice B rationaleLimiting the intake of calcium-rich foods is incorrect advice for a patient on long-term glucocorticoid therapy. Glucocorticoids can decrease calcium absorption from the gut and increase bone resorption, leading to osteoporosis. Therefore, patients on these medications should be encouraged to maintain an adequate intake of calcium and vitamin D to help preserve bone density. Normal total serum calcium levels range from 8.6 to 10.2 mg/dL.Choice C rationaleMonitoring for fractures over the next several months is an important instruction for a patient taking high doses of oral glucocorticoids long-term. Glucocorticoids increase the risk of osteoporosis and subsequent fractures, particularly vertebral compression fractures and hip fractures, due to their effects on bone metabolism. Regular monitoring and preventive measures are crucial.Choice D rationaleGlucocorticoids do not boost immunity; instead, they suppress the immune system by inhibiting the production and function of various immune cells and inflammatory mediators. This immunosuppressive effect is why they are used to treat autoimmune diseases like rheumatoid arthritis, but it also increases the risk of infections.
