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?
Age over 40 years
Daily walking 2 to 3 miles
Low-fat diet
Male gender
The Correct Answer is A
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.

Correct Answer is C
Explanation
Choice A reason: Throat irritation is a common albuterol side effect due to its deposition in the oropharynx during inhalation. It is not life-threatening and can be managed with rinsing or spacer use. This does not require immediate intervention compared to cardiovascular effects, as it does not compromise vital organ function.
Choice B reason: Uncontrollable shaking (tremors) is a frequent albuterol side effect, resulting from beta-2 receptor stimulation in skeletal muscles. It is usually transient and benign, not requiring immediate intervention. Monitoring is sufficient unless severe, as it does not pose an acute threat compared to cardiac irregularities.
Choice C reason: An irregular rapid heart rate (tachycardia or arrhythmia) is a serious albuterol side effect, as beta-2 agonists can stimulate beta-1 receptors in the heart, causing cardiovascular instability. This warrants immediate intervention, as it risks cardiac compromise, especially in emphysema patients with compromised respiratory and cardiac reserves.
Choice D reason: Increased anxiety is a possible albuterol side effect due to its stimulatory effects on the central nervous system. While distressing, it is not immediately life-threatening. It requires monitoring but is secondary to cardiovascular complications, which pose a greater acute risk in emphysema patients with wheezing.
Correct Answer is B
Explanation
Choice A reason: Anorexia is common in hepatitis due to systemic inflammation but is nonspecific, occurring in many conditions. Clay-colored stools directly indicate impaired bile excretion from liver dysfunction, a hallmark of hepatitis, making it a more diagnostic finding.
Choice B reason: Clay-colored stools are highly indicative of hepatitis, as liver inflammation impairs bile production or excretion, reducing bilirubin in feces. This causes pale stools, reflecting hepatic dysfunction, making it a key finding to confirm hepatitis over nonspecific symptoms like anorexia.
Choice C reason: Brown, foamy urine is not typical of hepatitis. Dark urine from bilirubinuria may occur, but foamy urine suggests proteinuria, unrelated to liver dysfunction. Clay-colored stools are more specific, indicating bile flow obstruction, a direct sign of hepatitis pathology.
Choice D reason: Hematemesis indicates gastrointestinal bleeding, not a primary hepatitis feature. While advanced liver disease may cause variceal bleeding, clay-colored stools are an earlier, more specific sign of hepatitis-related bile impairment, making them the priority finding in acute cases.
