A nurse is reviewing the laboratory values of a school-age child who has nephrotic syndrome. Which of the following laboratory values should the nurse expect?

Choice A reason: A blood pressure reading of 150/90 mmHg is significantly high for a 7-year-old child and indicates hypertension, which can be a serious complication of acute glomerulonephritis. It is a priority to report this finding to the provider as it may require immediate intervention.

Choice B reason: A BUN level of 20 mg/dL is within the normal range for children and is not typically a cause for immediate concern. However, it should be monitored along with other kidney function tests.

Choice C reason: Urine protein of 12 mg/dL is a common finding in acute glomerulonephritis due to increased permeability of the glomerular membrane. It is important but not as urgent as the blood pressure finding.

Choice D reason: 2+ pedal edema is a sign of fluid retention, which is expected in acute glomerulonephritis. While it should be addressed, it is not as immediately concerning as severe hypertension.

Choice A reason:

This option addresses electrical safety, which is important for preventing shocks and strangulation hazards in toddlers. However, it does not directly prevent burn injuries from hot water, which is the focus of the question. While hiding wires reduces overall household risks, it does not mitigate scalding hazards. Therefore, this choice is not the correct answer in the context of hot water burn prevention.

Choice B reason:

Turning pot handles toward the back of the stove is a well-known safety measure to prevent toddlers from pulling down hot pots and pans. This reduces the risk of scalds and burns in the kitchen environment. However, the question specifically emphasizes hot water burns, which are more commonly caused by tap water and bathing accidents. Thus, while helpful, this measure does not directly address the hazard highlighted in the scenario.

Choice C reason:

Encouraging outdoor play outside peak sun hours is a measure aimed at reducing sunburn and heat exposure. Sunburn is technically a type of burn, but it is not related to hot water scalds. The question focuses on preventing injuries from household hot water sources, making this option less relevant. While beneficial for overall child safety, it does not answer the specific teaching point.

Choice D reason:

Setting the water heater to 49°C (120°F) is the most effective intervention to prevent scald injuries from hot water in toddlers. Toddlers are at high risk of burns during bathing or when exposed to hot tap water. Lowering the water heater temperature reduces the severity of burns if accidental exposure occurs. This measure directly addresses the hazard in the question, making it the correct answer.
