Which of these is an age-related physiological change that occurs in older adults?
 
  1. Brain mass increases.
  2. GI motility increases.
  3. The kidneys filter better and function more efficiently as a client ages.
  4. Blood flow to the liver decreases.

Correct Answer: 4
Rationale 1: Brain mass typically gets smaller, not larger.
Rationale 2: GI motility decreases, not increases, with age.
Rationale 3: Kidney function declines, not improves, with advancing age.
Rationale 4: Liver blood flow typically decreases with advancing age.
Global Rationale: Liver blood flow typically decreases with advancing age. Brain mass typically gets smaller, not larger. GI motility decreases, not increases, with age. Kidney function declines, not improves, with advancing age.
