A nurse is collecting data for a middle aged client who has pyelonephritis. Which of the following finding should the nurse expect?

A. Weight gain: Weight gain is not typically associated with acute pyelonephritis. It may occur in chronic kidney disease or conditions causing fluid retention, but in the context of an acute infection, it is not an expected finding. B. Confusion: Confusion is more commonly seen in older adults with pyelonephritis, especially those with preexisting cognitive impairment or sepsis. In a middle-aged client, this is less likely to be a primary symptom. C. Flank pain: Flank pain is a classic symptom of pyelonephritis, resulting from inflammation and infection of the kidneys. It is usually accompanied by fever, dysuria, and urinary frequency or urgency. D. Hypotension: In the early stages of pyelonephritis, a client is more likely to be hypertensive or have a normal blood pressure. Hypotension is a late and ominous sign indicating the onset of septic shock.
