The nurse identifies several nursing problems for an older adult client with gastroenteritis who is experiencing fever, chills, anorexia, and diarrhea. The client has a history of a stroke with left-sided hemiplegia and is dependent on care provided by the spouse. Which problem should the nurse determine has the highest priority?

A. Fluid volume deficit. Gastroenteritis, characterized by fever, chills, anorexia, and diarrhea, can lead to significant fluid loss, especially in an older adult who may already have compromised fluid balance due to other factors such as stroke-related immobility. Fluid volume deficit is a critical problem that requires immediate attention to prevent complications such as hypovolemic shock. B. Bowel incontinence. While bowel incontinence is a concern, it is not as immediately life- threatening as fluid volume deficit. C. Caregiver role strain. While important for the client's overall well-being, caregiver role strain is a secondary concern compared to the client's physiological needs. D. Impaired bed mobility. Impaired bed mobility is a long-term issue that requires attention but is not as urgent as addressing the immediate physiological needs of fluid volume deficit.
