A nurse is caring for four clients in an emergency department. The nurse should plan to see which of the following clients first?

A. A client who is confused, is febrile, and has foul-smelling urine: These symptoms suggest a urinary tract infection potentially progressing to sepsis, which is serious but does not take priority over signs of possible stroke or brain injury. B. A client who has sickle cell disease and reports severe joint pain: Severe pain is expected in sickle cell crises and requires prompt management, but it is not as time-sensitive as neurologic deterioration. C. A client who has slurred speech, is disoriented, and reports a headache: These findings suggest a possible stroke or other neurological emergency such as a brain hemorrhage or increased intracranial pressure, which requires immediate evaluation and intervention. D. A client who has a dislocated left shoulder: Although painful and requiring attention, a shoulder dislocation is not immediately life-threatening and does not take precedence over potential neurologic compromise.
