A nurse is evaluating a client's understanding of food nutrition labels. Which of the following statements by the client indicates an understanding of the teaching?

Rationale

• Diarrhea: Diarrhea is common in both ulcerative colitis and Crohn's disease because chronic inflammation disrupts absorption and increases motility. UC typically presents with bloody diarrhea, while Crohn’s can present with non-bloody, intermittent diarrhea. Diverticulitis more often presents with left-lower-quadrant pain and constipation rather than chronic diarrhea.

• Steatorrhea: Steatorrhea is strongly associated with Crohn’s disease due to small-bowel involvement leading to fat-malabsorption. UC affects only the colon and does not impair fat absorption, so steatorrhea is not expected. Diverticulitis is a localized colonic infection and does not interfere with digestion or absorption.

• Weight loss: Weight loss occurs in both UC and Crohn’s because chronic inflammation increases metabolic demand and reduces nutritional intake. Malabsorption in Crohn’s disease further contributes to weight loss severity. Weight loss is not typical in diverticulitis unless the condition is prolonged or severe, so it is not strongly associated.

• Anemia: Anemia appears in both UC and Crohn’s disease due to chronic blood loss, reduced intake, and inflammation-driven suppression of erythropoiesis. UC often causes iron-deficiency anemia from recurrent rectal bleeding. Crohn’s may also cause anemia due to B12 or iron malabsorption. Diverticulitis does not typically cause chronic anemia.

• Fever: Fever is a sign of active inflammation and can occur in UC, Crohn’s flares, and acute diverticulitis. UC and Crohn’s involve systemic inflammatory activity during exacerbations. Diverticulitis produces fever due to infection of the diverticulum, making fever consistent across all three in varying degrees.

Rationale for correct choices

• Heart sounds: The presence of S3 and S4 heart sounds may indicate right ventricular strain or acute heart failure, which can occur secondary to a massive pulmonary embolism. This finding aligns with increased cardiac workload due to impaired pulmonary circulation. Heart sounds are not typically altered in pneumonia or pneumothorax unless severe cardiac compromise occurs.

• Respiratory pattern: Tachypnea and labored breathing can occur in all three conditions. In pulmonary embolism, rapid breathing compensates for hypoxemia. In pneumonia, increased respiratory rate results from impaired gas exchange and inflammation. In pneumothorax, rapid breathing occurs due to decreased lung expansion and oxygenation.

• Temperature: Fever (38.9° C/102° F) suggests an infectious process, consistent with pneumonia. Pulmonary embolism and pneumothorax typically do not present with elevated temperature unless secondary infection or inflammatory response is present.

• Lung sounds: Bilateral crackles indicate fluid or exudate in the alveoli. In pneumonia, crackles result from consolidation and inflammation. In pulmonary embolism, crackles may reflect pulmonary infarction or edema from right-sided heart strain. Pneumothorax generally produces absent or decreased breath sounds rather than crackles, so crackles are less indicative.
