While a child is hospitalized with acute glomerulonephritis, the parents ask why blood pressure readings are taken so often. Which response by the nurse is most accurate?

A. Sodium intake with meals and snacks affects the blood pressure: While sodium can influence blood pressure, this statement does not directly answer the parents’ question or explain the need for frequent monitoring during acute illness. B. Hypotension leading to sudden shock can develop at any time: Hypotension is not a typical complication of acute glomerulonephritis. The concern in this condition is usually fluid retention and hypertension, not shock from low blood pressure. C. Elevated blood pressure must be anticipated and identified quickly: Acute glomerulonephritis often leads to fluid retention and decreased kidney function, which can cause rapid-onset hypertension. Early detection is essential to prevent complications like seizures, heart failure, or encephalopathy. D. Blood pressure fluctuations means that the condition has become chronic: Fluctuations in BP do not necessarily indicate a chronic process. Acute glomerulonephritis is often self-limiting, and BP changes are common during the acute phase.
