A 5-year-old child with acute post-streptococcal glomerulonephritis is admitted to the pediatric unit. The child presents with periorbital edema, hypertension (BP 140/90 mmHg), and oliguria. Laboratory results show proteinuria and hematuria. Which nursing intervention should be the priority?

Priority is monitoring BP every 2 hours and seizure precautions to prevent hypertensive encephalopathy, the most dangerous complication. Other interventions are contraindicated or lower priority.

Core Nursing Explanation Key Concept Analysis: This question assesses the priority nursing intervention for a child with Acute Post-Streptococcal Glomerulonephritis (APSGN). The core pathophysiology involves inflammation of the glomeruli following a streptococcal infection, leading to impaired kidney function. This results in Fluid retention, Hypertension, and Oliguria. The most critical and immediate threat to this patient is not the kidney damage itself, but the severe complications arising from the resulting hypertension.

Answer Rationale: Key Point! The priority is Monitoring blood pressure every 2 hours and implementing seizure precautions. Severe, uncontrolled hypertension in APSGN can lead to Hypertensive encephalopathy, a life-threatening condition where high pressure in the brain causes cerebral edema, leading to seizures, headaches, and altered mental status. This is the most dangerous acute complication and requires vigilant monitoring and preventive safety measures. The nurse's primary role is to prevent harm, making this the top priority.

Distractor Analysis: Watch out for confusion!
① Encouraging increased fluid intake is contraindicated. The child is already fluid-overloaded (evidenced by edema, hypertension, and oliguria). Adding more fluid would worsen hypertension and edema, potentially leading to heart failure or pulmonary edema.
③ Administering diuretics immediately is not a nursing intervention; it is a medical order. While diuretics may be prescribed, the nurse's priority is first to assess and monitor for the most critical complication (hypertensive crisis). Jumping to medication administration without proper assessment violates the nursing process.
④ While rest is important to reduce metabolic demands on the kidneys, "restrict all physical activity and maintain strict bed rest" is an outdated and overly restrictive approach. Modern management focuses on balancing rest with quiet activity as tolerated. This intervention does not address the most immediate life-threatening risk.

Related Concepts: APSGN is characterized by the classic triad of Hematuria (often described as "cola-colored" or "smoky" urine), Edema (periorbital is common in children), and Hypertension. Management focuses on controlling hypertension (often with medications like calcium channel blockers), managing fluid balance (sodium and fluid restriction), and monitoring for complications.
Concept Summary

Component	Key Points for APSGN
Pathophysiology	Immune complex deposition in glomeruli post-Strep infection → inflammation → impaired filtration → fluid/Na+ retention, hematuria, proteinuria.
Classic Triad	Hematuria, Edema (periorbital), Hypertension.
Priority Complication	Hypertensive Encephalopathy (risk of seizures).
Priority Nursing Action	Frequent BP monitoring & seizure precautions.
Fluid Management	Fluid and sodium restriction, NOT encouragement.
Expected Lab Findings	Elevated ASO titer (evidence of recent Strep infection), Low C3 complement (Normal: 75-135 mg/dL), hematuria, proteinuria.

Side-by-Side Comparison!

Condition	Acute Glomerulonephritis (APSGN)	Nephrotic Syndrome
Primary Problem	Inflammation of glomeruli.	Increased permeability of glomeruli.
Key Lab Finding	Hematuria is prominent.	Massive Proteinuria is prominent (>>3.5 g/day).
Edema Character	Mild to moderate; often periorbital.	Severe, generalized (anasarca), pitting edema.
Blood Pressure	Often Elevated (Hypertension).	Often normal or low (due to hypoalbuminemia).
Serum Albumin	Usually normal.	Very Low (Hypoalbuminemia).
Priority Concern	Hypertensive crisis, encephalopathy.	Infection (due to lost immunoglobulins), thromboembolism (due to hypercoagulable state).

Anatomy, Physiology & Pharmacology Points Physiology: The glomerulus acts as a filter. Inflammation (glomerulonephritis) damages this filter, allowing red blood cells (RBCs) and some protein to pass through (hematuria/proteinuria) while impairing the removal of waste and regulation of fluid/electrolytes, leading to fluid retention and hypertension.
Pharmacology: Antihypertensives (e.g., Nifedipine - a calcium channel blocker) are first-line for hypertension in APSGN. Diuretics (e.g., Furosemide) may be used cautiously to reduce edema, but are not first priority over monitoring.
Memory Tips Mnemonic for APSGN Triad: "HEH" – Hematuria, Edema, Hypertension.
Priority Rule: Think "BP before Bed rest" or "Pressure before Pee" – Monitoring Blood Pressure for hypertensive encephalopathy is always the priority over managing oliguria or enforcing bed rest.
High-Frequency NCLEX Topics This is a classic High Yield pediatric renal disorder. The NCLEX loves to test:
1. Identifying priority assessments/interventions (ABCs – Airway, Breathing, Circulation; here, hypertension threatens cerebral circulation).
2. Differentiating between Glomerulonephritis and Nephrotic Syndrome (see comparison table).
3. Understanding contraindicated actions (e.g., giving more fluids to an overloaded patient).
Watch Out for Question Variations! * Instead of asking for the priority intervention, the question might ask: "Which finding requires immediate notification of the provider?" Answer: A sudden spike in BP or a complaint of severe headache/visual changes (signs of encephalopathy).
* The question could shift to patient/parent education: "Which statement by the parent indicates understanding of the child's care?" Correct answer would relate to sodium restriction or recognizing signs of worsening hypertension.
* It could be integrated with medication: The nurse is administering an antihypertensive. The priority action before administration is to assess the current blood pressure.

Nursing Clinical Practice Guide Clinical Scenario: You are the nurse admitting Liam, a 5-year-old, to the pediatric unit. His mother reports he had a "strep throat" two weeks ago. Now, his face, especially around his eyes, is puffy this morning, he has barely urinated, and his urine looks like cola. His initial BP is 142/92 mmHg.

Nursing Intervention Strategy:
1. Assessment: Immediately obtain a full set of vital signs, with emphasis on accurate BP measurement using a correct-sized cuff. Perform a focused neurological assessment (level of consciousness, headache, visual disturbances, irritability). Accurately measure and document intake and output (I&O). Assess edema (periorbital, dependent).
2. Planning & Implementation: The care plan prioritizes neurological safety and BP control. Place the child on seizure precautions (pad side rails, have suction/oxygen available). Schedule BP checks every 2-4 hours as ordered. Collaborate with the provider to obtain orders for antihypertensive medication. Implement fluid and sodium restrictions as prescribed (e.g., no added salt, avoid processed foods). Provide quiet, non-strenuous activities.
3. Patient/Family Education: Educate the parents on the importance of BP monitoring, the signs of hypertensive emergency (severe headache, vomiting, blurred vision, confusion), and the reason for fluid/salt restriction. Reassure them that most children with APSGN recover fully with proper management.
4. Evaluation: Evaluate for stable or decreasing BP, resolution of edema, adequate urine output, and absence of neurological symptoms.

Patient Safety and Precautions: Never encourage fluid intake in the oliguric phase. Handle the child gently due to possible hypertension-related headache and irritability. When diuretics are administered, monitor for electrolyte imbalances (hypokalemia with furosemide) and orthostatic hypotension.
Nursing Procedure & Medication Flow Blood Pressure Monitoring in a Child: Use a cuff width that is 40% of the arm circumference and length that covers 80-100% of the arm. Have the child sit quietly with feet flat. Take multiple readings if needed. Document the limb used and patient position.
Seizure Precautions Setup: Lower the bed, raise padded side rails, ensure the call light is within reach, and have emergency equipment (suction, oxygen, ambu bag) readily available in the room.
Medication: Nifedipine (Procardia): This is a common first-line antihypertensive. Nursing considerations: Monitor for side effects like flushing, headache, dizziness, and peripheral edema. Check BP before administration. For the liquid form, ensure accurate dose measurement.
A Word from Your Senior Nurse "In pediatrics, your assessment skills are everything. A child with APSGN might just seem 'puffy and cranky,' but that crankiness could be the first sign of a headache from skyrocketing blood pressure. You are the one at the bedside every two hours, charting that trend. Seeing a BP start to creep up and intervening early—calling the provider, administering ordered meds—is what prevents a seizure and a trip to the PICU. Remember, your priority is always to protect the brain and the heart. When you see edema + hypertension + oliguria, think 'fluid overload' and 'protect from pressure.' That clinical reasoning will guide you to the right answer every time."
