What laboratory values are expected for an 80-year-old male client?

For an 80-year-old male client, the expected laboratory values can often reflect the changes that occur with aging, including the body's adaptation to various physiological stressors. Option C highlights an increase in protein in the urine and slightly increased serum glucose levels, which can be indicative of age-related changes such as renal function decline or the onset of diabetes mellitus, conditions that are more prevalent in older adults.

Increased protein in the urine (proteinuria) can occur due to glomerular damage, reduced clearance, or other renal issues that could arise with age. This is significant as it can indicate underlying kidney disease or conditions that affect kidney function. Higher serum glucose levels might suggest that the client is experiencing insulin resistance or other changes that often occur as part of the aging process, including reduced pancreatic beta-cell function.

By contrast, the other options present laboratory values that might not align as closely with typical age-related changes. For example, increased WBC with decreased RBC (while one might expect some variations in blood cell counts with age, significant changes in WBC might suggest infection or hematologic issues), increased serum bilirubin and liver enzymes may indicate liver dysfunction or disease, and a decreased serum sodium accompanied by increased urine specific gravity could suggest possible issues with fluid balance
