A nurse has notified an 80-year-old client's physician that the client's laboratory values indicating kidney function have fallen below the minimum reference range
The nurse should be aware of what consideration that affects the interpretation of laboratory values in elderly clients? A) Levels of most laboratory values in older adults are more stable than those of younger people.
B) Laboratory values are considered an unreliable indicator of health status in older adults.
C) Laboratory values must be measured after a period of fasting in order to be considered accurate in older adults.
D) An older adult may have "normal" laboratory values that would be considered abnormal in a younger adult.
D
Feedback:
The norms of some lab values change somewhat with age. An abnormality in a younger person may be normal for an older person or vice versa. Not all lab values require fasting. Laboratory values of older clients have the potential to be volatile and unstable.
