A nurse is caring for a 28-year-old client with acute post-streptococcal glomerulonephritis following a recent throat infection, who presents with periorbital edema, hypertension (160/95 mmHg), oliguria, and hematuria. Which nursing intervention should be the highest priority?

Hypertension is a life-threatening complication in acute glomerulonephritis, requiring immediate monitoring and antihypertensive therapy to prevent stroke or heart failure. Other options like increased fluids or high-protein diet are not priority in this acute setting.

Core Nursing Explanation Key Concept Analysis: This question tests the nurse's ability to prioritize care for a patient with Acute Post-Streptococcal Glomerulonephritis (APSGN). The core pathophysiology involves an immune complex-mediated inflammation of the glomeruli following a streptococcal infection (e.g., strep throat). This inflammation damages the glomerular filtration membrane, leading to three key problems: 1) Sodium and water retention (causing edema and hypertension), 2) Decreased Glomerular Filtration Rate (GFR) (causing oliguria and azotemia), and 3) Loss of membrane integrity (causing hematuria and proteinuria).

Answer Rationale: Key Point! The highest priority is managing Hypertension (160/95 mmHg). In APSGN, hypertension is often severe and rapid in onset due to fluid overload and activation of the renin-angiotensin-aldosterone system (RAAS). Uncontrolled hypertension can lead to acute, life-threatening complications such as Hypertensive encephalopathy (headache, seizures, altered mental status) or Pulmonary edema. Therefore, vigilant monitoring and timely administration of prescribed antihypertensives are critical to prevent these complications and protect end organs.

Distractor Analysis:
• Watch out for confusion! Option ② (Encourage increased fluid intake) is incorrect and potentially harmful. The patient has Oliguria and edema, indicating the kidneys are not effectively excreting fluid. Increasing fluid intake would worsen fluid overload, hypertension, and edema. Fluid restriction is typically part of the management.
• Option ③ (Administer high-protein diet) is incorrect. While proteinuria may occur, a high-protein diet is not indicated in the acute phase. It can increase the metabolic waste products (like BUN) that the already compromised kidneys must filter, potentially worsening azotemia. A moderate or low-protein diet may be recommended.
• Option ④ (Provide frequent ambulation) is not the priority. While preventing complications like DVT is important, the patient's acute symptoms (edema, hypertension, oliguria) require more immediate medical and nursing management. Ambulation might not even be advisable if the patient is severely hypertensive or feeling unwell.

Related Concepts: The nursing priorities in APSGN follow the ABC (Airway, Breathing, Circulation) framework, with hypertension being a critical Circulation issue. Other key interventions include monitoring intake and output (I&O), daily weights, assessing for signs of worsening renal function (rising BUN/Creatinine), and administering antibiotics if needed to eradicate the streptococcal infection.
Concept Summary • Pathophysiology: Immune complexes deposit in glomeruli → Inflammation → ↓GFR, sodium/water retention, hematuria.
• Classic Triad: Edema (especially periorbital), Hypertension, Cola-colored urine (hematuria).
• Priority Nursing Dx: Risk for injury related to hypertension; Excess fluid volume.
• Key Labs: Elevated ASO titer (confirms recent strep infection), Elevated BUN/Creatinine, Hematuria on urinalysis.
Side-by-Side Comparison!

Feature	Acute Glomerulonephritis (APSGN)	Nephrotic Syndrome
Primary Problem	Inflammation of glomeruli	Increased permeability of glomeruli
Key Lab Finding	Hematuria (RBCs in urine)	Massive Proteinuria (>3.5g/day)
Edema Cause	Sodium/water retention (↓GFR)	Low serum albumin (protein loss)
Blood Pressure	Often Hypertensive	Variable (may be normal or low)
Dietary Management	Fluid & Sodium restriction	Moderate protein, Sodium restriction

Anatomy, Physiology & Pharmacology Points • Glomerulus Function: The glomerulus is the kidney's filtering unit. Damage here directly impairs filtration (↓GFR) and allows blood/protein to leak into urine.
• RAAS System: Kidney damage can trigger RAAS, causing vasoconstriction and aldosterone release, further increasing blood pressure and fluid retention.
• Common Antihypertensives: ACE inhibitors (e.g., lisinopril) or ARBs are often used as they reduce pressure in the glomeruli (decrease intraglomerular pressure), providing renal protection.
Memory Tips • Acute GN Triad: Remember "Hypertension, Edema, Hematuria" = "HEH" (like a surprised gasp when you see the BP!).
• Priority: Think "Blood Pressure before Protein." Managing hypertension (BP) is always more urgent than dietary protein adjustments.
High-Frequency NCLEX Topics NCLEX loves to test priority-setting in renal patients. APSGN is a classic scenario where you must choose the intervention that addresses the most immediate, life-threatening problem (hypertension) over other plausible but less critical measures like diet or ambulation.
Watch Out for Question Variations! • Instead of asking for a priority intervention, a question might ask: "Which finding requires immediate notification of the provider?" Answer: A sudden spike in BP or a change in mental status (sign of hypertensive encephalopathy).
• The question could shift to patient education: "The nurse should teach the client to report which symptom?" Key answers: Severe headache, blurred vision, decreased urine output, or recurrence of dark urine.

Nursing Clinical Practice Guide Clinical Scenario: You are the nurse on a medical-surgical unit. Your patient, a 28-year-old previously healthy male, was admitted yesterday with APSGN. He has significant periorbital edema, complains of a headache, and his BP has been labile, ranging from 150/92 to 165/98 mmHg. His urine output for the last shift was only 200 mL (oliguria).

Nursing Intervention Strategy:
1. Assessment: Perform focused assessments every 4 hours (or more frequently per order): Neurological checks (for encephalopathy), lung sounds (for crackles indicating pulmonary edema), precise I&O, daily weight on the same scale at the same time, and monitoring edema.
2. Planning & Implementation:
• Hypertension Management: Administer scheduled antihypertensives on time. For PRN medications, know the parameters (e.g., give for SBP >160). Ensure a quiet environment, limit stimuli, and assist with stress-reduction techniques.
• Fluid Management: Implement fluid restriction as ordered (e.g., 1500 mL/day). Provide mouth care to alleviate thirst. Educate the patient on the reason for the restriction.
• Diet: Collaborate with dietary services to provide a low-sodium, moderate-protein diet. Educate on reading food labels for sodium content.
3. Evaluation: Evaluate the effectiveness of interventions by tracking trends: Is the BP trending down? Is daily weight decreasing (indicating fluid loss)? Is urine output improving?
Patient Safety and Precautions:
• Key Point! Never encourage fluid intake in a patient with oliguria and edema without a specific order. This is a common nursing error.
• Monitor for signs of Hyperkalemia (muscle weakness, EKG changes) due to reduced renal potassium excretion. Hold potassium-sparing diuretics or potassium supplements if hyperkalemia is suspected and notify the provider.
• When administering diuretics (like furosemide), monitor for electrolyte imbalances (hypokalemia, hyponatremia) and orthostatic hypotension.
Nursing Procedure & Medication Flow Administering Antihypertensives in Renal Patients:
1. Check BP immediately before administration.
2. Verify the medication, dose, and route. Common drugs: ACE inhibitors (monitor for cough, angioedema), beta-blockers (monitor heart rate), calcium channel blockers.
3. Administer as prescribed. For IV antihypertensives, use an infusion pump and monitor BP frequently (e.g., every 5-15 minutes initially).
4. Reassess BP 30-60 minutes after oral administration (per facility policy) to evaluate effect.
5. Educate the patient to change positions slowly to prevent falls due to postural hypotension.
A Word from Your Senior Nurse "In renal cases like this, your eyes and ears are your best tools. That periorbital edema and that high blood pressure reading aren't just numbers on a chart—they're your patient's kidneys crying out for help. Prioritizing BP management isn't just about following an order; it's about preventing a stroke in a young person. Always connect the dots: strep throat → immune reaction → kidney inflammation → fluid backup → high BP. When you understand the 'why,' choosing the priority action becomes second nature, both on the NCLEX and at the bedside."
