A nurse is assessing a child who has rubeola. Which of the following findings should the nurse expect?

A. Mild hematuria. One of the hallmark signs of glomerulonephritis is hematuria (presence of blood in the urine). Mild hematuria is common and is often associated with glomerular injury, which allows red blood cells to pass through the glomerular filtration barrier.

B. Hyponatremia. Hyponatremia (low sodium levels) is not typically associated with glomerulonephritis. However, in severe cases of kidney dysfunction, fluid retention can lead to dilutional hyponatremia, but it is not a primary finding in glomerulonephritis.

C. Absent urine protein. Proteinuria (presence of protein in the urine) is a common finding in glomerulonephritis due to damage to the glomerular filtration barrier. It is typically present, though the amount may vary.

D. Decreased blood potassium. Hyperkalemia (increased potassium levels) is more commonly seen in acute kidney injury and glomerulonephritis due to decreased kidney function. Decreased potassium levels are not typical in this condition.

A. "Ask the child to hold their breath while the IV catheter is placed." Holding breath can increase anxiety and is not necessary for IV insertion. Instead, distraction techniques (e.g., deep breathing, counting) are more effective.
B. "Explain the procedure to the child in detail." Preschoolers have limited understanding of medical procedures. Instead, use simple, age-appropriate language and possibly a demonstration with a toy.
C. "Apply vapocoolant spray before the IV insertion." Vapocoolant spray or topical anesthetics (e.g., EMLA cream) help reduce pain and anxiety associated with IV insertion.
D. "Place the IV catheter on the dominant arm." IV placement is typically based on vein accessibility, not dominance. However, placing it on the non-dominant arm may be preferable to avoid interference with activities.
