A 5-year-old child with acute post-streptococcal glomerulonephritis is admitted to the pediatric unit. The child presents with periorbital edema, hematuria, and hypertension. Which nursing intervention should be the highest priority?

Highest priority is monitoring BP every 2 hours and implementing seizure precautions due to risk of hypertensive encephalopathy and seizures from severe hypertension in APSGN. Other interventions (increasing fluids, diuretics, high-protein diet) are less urgent or contraindicated.

Clinical Context and Pathophysiology

Acute post-streptococcal glomerulonephritis (APSGN) is an immune-mediated inflammatory condition affecting the renal glomeruli, typically developing 1 to 2 weeks after a group A beta-hemolytic streptococcal infection of the pharynx or skin. The condition is triggered by the deposition of circulating immune complexes within the glomerular basement membrane, which activates the complement system and leads to a marked reduction in serum complement C3 levels ^[3][4]. This inflammatory cascade results in glomerular swelling, reduced capillary lumen size, and a consequent decrease in the glomerular filtration rate (GFR).

The classic clinical presentation, as seen in this 7-year-old child, includes the triad of edema, hematuria, and hypertension. Periorbital edema is often the first noticeable sign, resulting from sodium and water retention due to the impaired GFR ^[3]. Hematuria, which can be microscopic or gross, arises from the structural damage to the glomerular capillary walls, allowing red blood cells to pass into the urine ^[1][4]. Hypertension is a direct consequence of the expanded intravascular volume (hypervolemia) caused by salt and water retention, not from increased systemic vascular resistance ^[3][4]. This pathophysiological sequence is critical for understanding the prioritization of nursing care.

Analysis of the Highest Priority Intervention

The correct answer is 1. Monitor blood pressure every 2 hours and implement seizure precautions. In a child with APSGN, hypertension is the most immediate and life-threatening complication. The hypervolemia-induced elevation in blood pressure can be severe and rapid in onset, placing the child at significant risk for hypertensive encephalopathy, a condition that can manifest as severe headache, vomiting, visual disturbances, and generalized seizures ^[3]. The nurse’s highest priority is to detect and prevent neurological deterioration. Frequent blood pressure monitoring, as specified every 2 hours, allows for the early identification of worsening hypertension. Implementing seizure precautions—such as padding the side rails, ensuring suction equipment and oxygen are at the bedside, and keeping the bed in the lowest position—is a proactive safety measure to protect the patient from injury should a seizure occur ^[1]. This intervention directly addresses the most acute risk to the patient’s airway, breathing, and neurological status, aligning with the nursing principle of prioritizing physiological integrity and safety.

Why Other Options Are Incorrect

- 2. Encourage increased fluid intake to promote kidney function: This intervention is contraindicated in the acute phase of APSGN. The underlying problem is not dehydration but hypervolemia due to the kidneys' inability to excrete sodium and water effectively ^[3]. Encouraging fluids would worsen the fluid overload, exacerbating hypertension, edema, and the risk of complications like pulmonary edema, a rare but critical finding reported in severe pediatric cases ^[1]. Fluid management typically involves restriction, not encouragement.

- 3. Administer diuretics as ordered to reduce edema: While administering diuretics is a crucial medical intervention for managing hypervolemia and hypertension in APSGN, it is not the highest nursing priority action. Medication administration is a dependent nursing function that requires a valid provider order. The question asks for the nursing intervention of highest priority, which focuses on independent assessment and safety measures. The nurse must first establish a baseline and continuously monitor the parameter (blood pressure) that the diuretic is intended to treat. Furthermore, seizure precautions are an independent, critical safety intervention that does not require an order and protects the patient from a direct consequence of the primary problem.

- 4. Provide a high-protein diet to replace protein lost in urine: This intervention is not indicated and reflects a misunderstanding of the disease process. While proteinuria is a common finding in APSGN, it is generally mild to moderate and not of the magnitude that causes significant protein depletion ^[3][4]. The primary dietary concern in the acute phase is not protein replacement but the restriction of sodium and fluid to manage hypertension and edema. A high-protein diet would place an unnecessary metabolic load on the already inflamed and functionally compromised kidneys.

Clinical Reasoning and NCLEX-RN Application

This question tests the ability to apply the nursing process in an acute pediatric setting. The nurse must analyze the clinical data (periorbital edema, hematuria, hypertension) and recognize that the hypertension is the most immediate threat to the child's safety due to the risk of neurological complications ^[3]. The priority nursing action is an independent intervention that involves continuous assessment (frequent BP monitoring) and a safety measure (seizure precautions) to mitigate the most serious potential harm. This approach follows the clinical reasoning hierarchy of addressing the most life-threatening risk first, a core concept for the NCLEX-RN examination. The case report of a child with PSGN presenting with severe respiratory distress and irritability underscores the rapid and severe nature of complications that can arise when fluid overload and hypertension are not promptly managed ^[1].
