The nurse is reviewing risk factors for cholelithiasis in a client’s history. Which factor most significantly increases the client’s risk for developing gallstones?

Choice A reason: Age over 40 increases cholelithiasis risk due to reduced gallbladder motility and increased bile cholesterol saturation, promoting gallstone formation. Aging alters bile composition, with higher lithogenic potential, making older adults more susceptible to cholesterol gallstones, a primary type in Western populations.

Choice B reason: Daily walking of 2 to 3 miles reduces cholelithiasis risk by promoting physical activity, which enhances gallbladder motility and reduces bile stasis. Exercise lowers cholesterol levels in bile, decreasing stone formation, making this a protective factor rather than a risk.

Choice C reason: A low-fat diet decreases cholelithiasis risk by reducing dietary cholesterol intake, which lowers bile cholesterol saturation. This promotes healthier bile composition, reducing the likelihood of cholesterol gallstone formation, making it a protective dietary habit rather than a risk factor.

Choice D reason: Male gender is associated with a lower risk of cholelithiasis compared to females, who have higher estrogen levels that increase bile cholesterol. Men have less lithogenic bile, making gender a protective factor, not a significant risk, unlike age-related changes.

Choice A reason: Frequent small meals reduce gastroesophageal reflux by minimizing gastric distension, which decreases pressure on the lower esophageal sphincter. This prevents acid reflux into the esophagus, alleviating heartburn and irritation, making it an effective dietary strategy for managing GERD symptoms.

Choice B reason: Switching to decaffeinated coffee and tea may reduce reflux triggers, as caffeine relaxes the lower esophageal sphincter. However, small meals are more effective, as they directly reduce gastric volume and sphincter pressure, providing broader symptom relief than caffeine avoidance alone.

Choice C reason: Avoiding milk and cream is relevant for some GERD patients, as high-fat foods delay gastric emptying, increasing reflux. However, frequent small meals address the root cause of reflux by reducing gastric pressure, making this a more universally effective strategy than specific food avoidance.

Choice D reason: Listing high-dairy snack foods reinforces avoidance but is less direct than recommending small meals. Dairy may trigger reflux in some, but frequent small meals broadly reduce gastric distension and sphincter pressure, offering a more immediate and effective GERD management strategy.
