11. The "normal" oxygen saturation in older adults may be 90% or greater in arterial blood.1 pointTrueFalseMaybe

Answer

The statement suggests that the normal oxygen saturation level in older adults may be 90% or greater in arterial blood.

1. Understanding Normal Values: Generally, normal oxygen saturation levels for adults, including older adults, range from 95% to 100%. However, levels of around 90% in older adults can sometimes still be considered acceptable due to various factors such as chronic respiratory conditions.

2. Implications of the Statement: The statement implies that if an older adult has an oxygen saturation of 90%, it may be a cause for concern, but for some individuals with pre-existing health conditions, it might not be.

3. Concluding Consideration: Given this context, the question of whether the oxygen saturation can be 90% or greater touches on the variability of individual health situations.

Final Answer

True. Normal oxygen saturation in older adults may be 90% or greater in arterial blood under specific circumstances, although levels are typically expected to be higher.
