A nurse is teaching a newly licensed nurse about physiological changes in the digestive system that occur with aging.
The nurse should include older adults might experience which of the following physiological changes?
Increased muscle tone of the bowel.
Increased gastric acid production.
Decreased pH of the stomach.
Decreased intestinal peristalsis.
The Correct Answer is D
Choice A rationale
Aging usually leads to a decrease in muscle tone of the bowel rather than an increase, which can result in slower bowel movements and constipation.
Choice B rationale
Gastric acid production tends to decrease with age, not increase. This can affect the digestion and absorption of nutrients, and also increase the risk of stomach infections.
Choice C rationale
The pH of the stomach tends to become less acidic (increase) as one ages, not decrease. This is often due to the reduced production of gastric acid.
Choice D rationale
Decreased intestinal peristalsis is a common physiological change in older adults. This slowing down of the intestinal movements can lead to constipation and other digestive issues.

Correct Answer is C
Explanation
Choice A rationale
Returning the opened medication to the medication cart is inappropriate because once a medication is opened and refused by a client, it must be disposed of properly. This action helps maintain safety and prevents contamination.
Choice B rationale
Reporting the incident to the provider is not necessary in this context as the refusal to take medication can be managed by the nurse by following the facility's protocol.
Choice C rationale
Filling out an incident report is required because the client's refusal to take the medication is considered a significant event. Incident reports are used to document and analyze such events to improve patient care and safety.
Choice D rationale
Notifying the facility's ethics committee is unnecessary for a medication refusal incident, as it does not involve an ethical dilemma requiring their intervention.
Correct Answer is D
Explanation
Choice A rationale
Collecting two stool specimens from the same area of the stool is incorrect because specimens should be taken from different areas to ensure a representative sample of the stool for testing.
Choice B rationale
Using toilet paper to transfer the stool specimen is not recommended as it can contaminate the sample and interfere with test results.
Choice C rationale
Applying four drops of developing solution to each stool specimen is incorrect. The usual procedure involves applying a specific number of drops as indicated by the test instructions, which may vary.
Choice D rationale
Waiting 30 seconds after applying the developing solution is correct. This waiting period allows the test to react and provide accurate results for the presence of occult blood.
