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
Documenting the medication administration is important but should be done after administering the medication. Documentation ensures proper tracking and accountability but does
not address immediate patient safety concerns like checking for allergies.
Choice B rationale
Mixing the medication at the client's bedside may ensure that the medication is prepared correctly and the client receives it promptly, but it doesn't address the critical step of
ensuring the client's safety by checking for allergies first.
Choice C rationale
Checking the client for allergies is crucial before administering any medication, including powdered forms. Allergic reactions can be severe or life-threatening, so it’s essential to
ensure that the client isn’t allergic to the medication. This step ensures the safety and well-being of the client and prevents potential adverse reactions.
Choice D rationale
Determining the client's response to the medication is important for assessing the medication's effectiveness and identifying any adverse reactions, but it occurs after administration.
Checking for allergies precedes all these steps to prevent any initial harm.
Correct Answer is D
Explanation
Choice A rationale
A sigmoid colostomy usually produces stool that is more formed compared to an ileostomy. This is because the colostomy is created from the sigmoid colon, where water absorption occurs.
Choice B rationale
The stoma should not be painful after the procedure. Pain may indicate complications, and the stoma itself lacks nerve endings.
Choice C rationale
The stoma should be a bright red or pink color, indicating good blood supply. A purple color could suggest ischemia or poor blood flow.
Choice D rationale
A sigmoid colostomy is typically located in the left lower abdomen because the sigmoid colon is situated in this area of the body.
