The nurse who is caring for a group of elderly residents in a long-term care facility understands that the aging process influences the recommended dietary allowance (RDA) needs in this population
What statement by the nurse is most accurate concerning elderly adults?
1. "Normal aging causes a decline in skin turgor, producing an increase in metabolism of vitamins."
2. "Normal aging causes an increase in renal excretion of fat-soluble vitamins in the urine."
3. "Normal aging causes a stagnation of liver enzymes that aid in the dissection of water-soluble vitamins."
4. "Normal aging causes a reduction of gastric absorption, producing vitamin deficiencies."
Correct Answer: 4
Rationale 1: Although normal aging includes a decline in skin turgor, this does not affect the metabolism of vitamins.
Rationale 2: The normal aging process does not increase renal excretion of fat-soluble vitamins in the urine.
Rationale 3: Aging does not cause a stagnation of liver enzymes that aid in the dissection of water-soluble vitamins.
Rationale 4: As part of the normal aging process, gastric absorption is reduced, causing decreased absorption of vitamins.
Global Rationale: With normal aging, the absorption of food diminishes and the quantity of ingested food is often reduced, leading to a higher risk of vitamin deficiencies in older adults. Although normal aging includes a decline in skin turgor, this does not affect the metabolism of vitamins. The normal aging process does not increase renal excretion of fat-soluble vitamins in the urine. Aging does not cause a stagnation of liver enzymes that aid in the dissection of water-soluble vitamins.
