In the scenario of an 82-year-old male in end-stage renal failure with dyspnea, which symptom might also be expected?

In the case of an 82-year-old male experiencing end-stage renal failure and dyspnea, weight gain is a common symptom to anticipate. This occurs largely due to the body's inability to effectively eliminate excess fluid and waste products. As the kidneys fail, fluid retention can lead to edema (swelling) and increased body weight, which can exacerbate respiratory symptoms such as dyspnea. The accumulation of fluid can be particularly problematic for those in renal failure, as it can contribute to pulmonary congestion and further respiratory distress.

In contrast, increased urine output is typically not expected in end-stage renal failure because the kidneys are less capable of producing urine as they become severely impaired. Hyperactive bowel sounds might suggest gastrointestinal disturbances unrelated to renal failure, while a reduced respiratory rate could indicate respiratory distress or other underlying issues but would not commonly be directly linked to fluid retention associated with end-stage renal failure.
