In a child with acute glomerulonephritis, which finding should the nurse expect?

In a child with acute glomerulonephritis, periorbital edema is a common finding. This condition often follows a streptococcal infection and is characterized by inflammation of the glomeruli. The inflammation leads to fluid retention, which is particularly noticeable around the eyes, resulting in swelling. This fluid retention can be attributed to changes in the kidney’s ability to filter blood properly, leading to the accumulation of excess fluid in the interstitial spaces of the body.

The other symptoms listed do not typically align with acute glomerulonephritis. For instance, hyperactivity is not a common presentation and does not correlate with the physical changes associated with this kidney condition. While a mild fever may occur, it is not generally above 101°F and is not a defining characteristic of the disease. Additionally, excessive urination is generally associated with other conditions, such as diabetes, rather than acute glomerulonephritis, where there is usually reduced urine output due to the kidney's impaired function.

Therefore, periorbital edema is a hallmark sign due to the combination of fluid retention and the location of the swelling, making it the expected finding in such a pediatric patient.
