Question 3 of 5
The nurse is educating an older adult patient with reduced cortisol levels. Which statement indicates that the patient accurately understands the nurse's teaching?

Rationale: Cortisol is a mineralocorticoid produced by the adrenal glands. Cortisol acts to increase glucose levels in the blood. Cortisol also helps counteract the inflammatory response. The reduced production of cortisol hinders the older adult in dealing with stress.
Question 4 of 5
The nurse is caring for an 80-year-old patient with a history of type 2 diabetes and hypothyroidism. The physician wants to evaluate the patient's blood glucose levels and orders a fructosamine assay. Which factor best explains why the physician chose this test over other blood glucose tests?
Correct Answer: A
Rationale: Fructosamine measures glycated serum proteins, reflecting glucose control over 2-3 weeks, shorter than the 2-3 months of hemoglobin A1c, making it ideal for recent monitoring, especially in conditions like hypothyroidism that may affect A1c reliability.
