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.

Correct Answer is A
Explanation
Choice A reason:
The urea breath test is typically used to diagnose Helicobacter pylori (H. pylori) infection in the stomach. H. pylori can lead to gastritis and ulcers, which can interfere with nutrient absorption and contribute to imbalanced nutrition.
Choice B reason:
Impaired dentition related to gingivitis is not directly related to the need for a urea breath test. This diagnosis pertains to dental health, not gastric health.
Choice C reason:
Diarrhea related to Clostridium difficile infection is not directly related to the need for a urea
breath test. This diagnosis pertains to a bacterial infection in the colon, not H. pylori infection in the stomach.
Choice D reason:
Risk for impaired skin integrity related to peptic ulcers is also not directly related to the need for a urea breath test. This diagnosis pertains to potential skin breakdown due to ulcers, not the
assessment of H. pylori infection.
Correct Answer is D
Explanation
Choice A reason:
Severe diarrhea can be a symptom of both Crohn's disease and ulcerative colitis and does not specifically indicate one over the other.
Choice B reason:
Involvement of the rectal mucosa is more indicative of ulcerative colitis rather than Crohn's disease, as Crohn's disease can affect any part of the digestive tract.
Choice C reason:
The presence or absence of blood in stool is not a definitive indicator of either Crohn's disease or ulcerative colitis, as both conditions can involve bleeding.
Choice D reason:
This statement is correct. A pattern of distinct exacerbations and remissions is more characteristic of Crohn's disease, whereas ulcerative colitis often presents with continuous, chronic symptoms.
