A nurse is performing an abdominal assessment of an older adult patient. When collecting and analyzing data, the nurse should be cognizant of what age-related change in gastrointestinal structure and function?
Increased gastric motility
Increased gag reflex
Decreased mucus secretion
Decreased gastric pH
The Correct Answer is C
Choice A reason:
In older adults, gastric motility tends to decrease rather than increase.
Choice B reason:
The gag reflex may diminish with age, making older adults more prone to swallowing difficulties.
Choice C reason:
This statement is correct. With aging, there is a decrease in mucus secretion in the gastrointestinal tract, which can lead to dryness and potential discomfort.
Choice D reason:
Gastric pH tends to increase with age, which can affect the digestion and absorption of certain nutrients.
