A nurse is assessing a 45-year-old client diagnosed with acute glomerulonephritis. Which assessment finding would be the MOST concerning and require immediate intervention?

Severe hypertension (180/110 mmHg) with headache indicates hypertensive crisis requiring immediate intervention to prevent stroke or seizures. Other findings are expected in acute glomerulonephritis but less urgent.

Core Nursing Explanation Key Concept Analysis: This question assesses the nurse's ability to prioritize life-threatening complications in a patient with Acute Glomerulonephritis (AGN). AGN is an inflammatory condition of the glomeruli, often post-streptococcal, leading to impaired kidney function. The primary pathophysiological concerns are fluid retention, hypertension, and azotemia (buildup of nitrogenous waste). The most critical, immediate threat is Key Point! hypertensive emergency, which can lead to encephalopathy, seizures, or stroke.

Answer Rationale: Option ③ is correct because a blood pressure of 180/110 mmHg accompanied by a severe headache is a classic sign of hypertensive encephalopathy. This is a medical emergency. The headache indicates increased intracranial pressure due to severe, uncontrolled hypertension. Immediate intervention (e.g., IV antihypertensives, neurological monitoring) is required to prevent permanent brain damage or death. This finding supersedes other expected, though abnormal, manifestations of AGN.

Distractor Analysis:
Watch out for confusion! Option ① (Mild periorbital edema) is a common and expected finding in AGN due to sodium and water retention. It requires monitoring but is not an immediate crisis.
Option ② (Urine output of 400 mL/8hrs) equates to 50 mL/hr, which is above the threshold for oliguria (

Nursing Clinical Practice Guide Clinical Scenario: You are the nurse on a medical-surgical unit. Mr. Johnson, 45, was admitted yesterday with a diagnosis of acute glomerulonephritis following a recent strep throat infection. During your morning assessment, he reports a sudden, severe pounding headache and appears restless. You immediately check his vital signs.

Nursing Intervention Strategy:

1. Immediate Assessment (ABCs):
   • Airway/Breathing: Ensure patent airway. Listen for crackles (signs of pulmonary edema).
   • Circulation: Re-check BP in both arms. Assess heart rate, rhythm, and peripheral pulses.
   • Neurological: Perform a focused neuro check: Level of consciousness (LOC) using AVPU or GCS, pupil size and reaction, presence of nausea/vomiting, visual disturbances, or focal weakness. Key Point! Document baseline thoroughly.
2. Immediate Action:
   • Stay with the patient. Call for help (use call light) and notify the provider immediately with SBAR report: Situation (client with AGN), Background (new severe headache), Assessment (BP 180/110, neuro findings), Recommendation (requesting urgent orders).
   • Elevate the head of the bed to 45-90 degrees to promote venous return and decrease intracranial pressure.
   • Ensure a quiet, calm environment with dim lighting to minimize stimulation.
3. Anticipate Provider Orders:
   • IV access for emergency medication administration.
   • STAT labs (electrolytes, BUN, creatinine).
   • IV antihypertensive medication (e.g., labetalol drip) with continuous BP monitoring.
   • Possible transfer to a higher level of care (e.g., ICU).

Patient Safety and Precautions:

• Medication Caution: When administering IV antihypertensives for a hypertensive emergency, the goal is a controlled, gradual reduction (e.g., lowering mean arterial pressure by no more than 25% in the first hour). Too rapid a drop can cause cerebral or renal hypoperfusion.
• Fall Risk: A patient with a severe headache and potential dizziness from high BP or medications is at high fall risk. Keep bed in low position, side rails up, and call light within reach.
• Fluid Management: Strict intake and output (I&O) monitoring and daily weights are essential. Adhere to fluid restriction orders (if present) to manage volume overload.

Nursing Procedure & Medication Flow Managing Hypertensive Emergency in AGN:

1. Assessment: Continuous cardiac and BP monitoring. Neurological checks every 15-30 minutes initially.
2. Medication Administration:
   • Drug Example: Labetalol IV: It is both an alpha and beta blocker. It lowers BP without causing significant reflex tachycardia.
   • Administration: Often given as an IV bolus (e.g., 20 mg over 2 min) or as a continuous infusion. Monitor for bradycardia and bronchospasm (caution in asthma patients).
3. Evaluation: Monitor BP response every 5-15 minutes during initial treatment. Assess for resolution of headache and improvement in neurological status. Document all findings and interventions.

A Word from Your Senior Nurse "Remember, in conditions like glomerulonephritis, the kidneys are the primary problem, but the brain and heart are the primary targets of the complications. Your vigilant assessment is the first line of defense. That severe headache isn't just a complaint—it's a red flag waving, telling you that the pressure inside the patient's skull is rising. Catching this early and acting decisively can prevent a catastrophic stroke. On the NCLEX and in practice, always link the patho (inflamed glomeruli → fluid retention → high BP) to the potential outcome (hypertensive encephalopathy). Think like a nurse who saves brains, not just one who charts vital signs!"
