Which assessment finding would be most concerning and require immediate intervention? The nurse is evaluating a preschool child diagnosed with nephrotic syndrome who has been receiving corticosteroid therapy for 2 weeks. ## 보기 1. Periorbital edema that is more pronounced in the morning 2. Blood pressure of 140/90 mmHg with complaints of headache **✔ 정답** 3. Weight gain of 2 pounds over the past week 4. Proteinuria of 3+ on dipstick urinalysis **정답: 2** ## 해설 Hypertension (140/90 mmHg) with headache in a child with nephrotic syndrome indicates potential complications like hypertensive encephalopathy requiring immediate intervention. Other findings (edema, weight gain, proteinuria) are typical and less urgent. ## 심화 해설 Clinical Context In a child with nephrotic syndrome receiving corticosteroid therapy, the nurse must prioritize assessment findings that indicate a life-threatening complication. While edema, weight gain, and proteinuria are expected manifestations of the disease process, a sudden elevation in blood pressure with neurological symptoms signals a hypertensive emergency. Correct Answer Analysis Posterior reversible encephalopathy syndrome (PRES) is an acute neurological condition most often associated with severe hypertension, renal dysfunction, and exposure to immunosuppressive agents [4]. The blood pressure reading of 140/90 mmHg in a preschool-aged child represents significant hypertension, and when coupled with a complaint of headache, it becomes the most concerning finding. This clinical presentation is a classic prodrome for PRES, which can progress to seizures, visual disturbances, and altered mental status if the hypertension is not immediately controlled [4]. The reported mortality for PRES ranges from 10 to 19%, and up to 40–44% of patients experience persistent neurological deficits, making this a finding that demands urgent intervention [4]. Distractor Analysis - **Option 1:** Periorbital edema that is more pronounced in the morning is a classic, expected finding in nephrotic syndrome due to fluid shifts and hypoalbuminemia. While it requires monitoring and comfort measures, it does not represent an immediate threat to life. - **Option 3:** A weight gain of 2 pounds over one week reflects ongoing fluid retention, which is consistent with the disease pathophysiology. This finding indicates that the edema is progressing, which warrants ongoing assessment and possible adjustment to fluid management, but it is not an emergency in the absence of respiratory distress or other critical signs. - **Option 4:** Proteinuria of 3+ on dipstick is a hallmark diagnostic criterion for nephrotic syndrome and an expected finding during a relapse. The persistence of proteinuria indicates that remission has not yet been achieved with the current corticosteroid regimen, but it does not by itself necessitate immediate, emergent intervention. Pathophysiology and Clinical Reasoning The development of hypertension in a child with nephrotic syndrome can be multifactorial, stemming from fluid overload, altered renin-angiotensin-aldosterone system activity, and the vasoconstrictive effects of corticosteroid therapy. The updated KDIGO 2025 Clinical Practice Guideline for the management of nephrotic syndrome in children emphasizes the importance of monitoring for treatment complications, which includes the hypertensive effects of corticosteroids . The nurse's recognition that a severe headache in the setting of hypertension is a neurological red flag is the critical clinical judgment point. This symptom suggests that the cerebral autoregulatory mechanisms are being overwhelmed, leading to endothelial dysfunction and vasogenic edema in the brain, which is the underlying mechanism of PRES [4]. Immediate intervention involves notifying the healthcare provider for prompt antihypertensive therapy to prevent irreversible neurological injury.

PRES mortality ranges from 10–19%, and 40–44% of patients may have persistent neurological deficits. Immediate blood pressure control is critical to prevent progression to seizures, visual disturbances, or altered mental status. CautionExpected findings like periorbital edema, gradual weight gain, and proteinuria do not require immediate intervention. Prioritize neurological assessment and blood pressure reduction over managing chronic disease manifestations. ## 핵심 개념 - **Posterior Reversible Encephalopathy Syndrome (PRES)** — An acute neurological condition associated with severe hypertension, renal disease, and immunosuppressive therapy, presenting with headache, seizures, and visual changes. - **Nephrotic Syndrome** — A kidney disorder characterized by massive proteinuria, hypoalbuminemia, hyperlipidemia, and edema. - **Hypertensive Emergency** — Severely elevated blood pressure with evidence of acute target organ damage, such as neurological symptoms. ## 같은 주제 문제 - [A 6-year-old child with nephrotic syndrome is being assessed by the nurse.
