Nursing Clinical Practice Guide
Clinical Scenario: You are the nurse for Mr. Johnson, a 68-year-old man in the ICU with MSOF secondary to septic shock. He is intubated, sedated on a Propofol drip, on Norepinephrine for blood pressure support, and receiving continuous renal replacement therapy (CRRT). During your hourly rounding, you note that his sedation has been weaned per protocol, but he is not following commands as he was 4 hours ago. He is now agitated, trying to pull at his endotracheal tube (ETT), and his eyes are not tracking your movement. His vitals show: BP 92/58 (on norepinephrine), HR 112, SpO2 94% on ventilator (FiO2 50%, PEEP 10), and a urine output of 20 mL/hr via Foley catheter.
Nursing Intervention Strategy:- 1Immediate Assessment (First 60 seconds)• Airway & Breathing: Ensure ETT is secure at the lip (e.g., 23 cm), listen for bilateral breath sounds, check ventilator for disconnection or high-pressure alarms. Suction if needed.
• Circulation: Check the norepinephrine drip IV site for patency and infiltration. Confirm the pump is running at the ordered rate.
• Disability (Neurological): Perform a rapid Glasgow Coma Scale (GCS) assessment. Note pupil size, equality, and reactivity.
• Exposure/Environment: Check bedside glucose monitor. Rule out obvious causes like a kinked Foley catheter causing bladder distension/pain.
- 2Immediate Actions & Communication• Call for help. Inform the charge nurse and the covering physician/resident immediately. Your report: "This is Nurse [Your Name] in ICU bed 5. I have a rapid change in neuro status. Patient is now agitated, not following commands, GCS dropped from 10 to 6. Vitals are stable on current support. Requesting immediate evaluation."
• Prepare for escalation: Have the emergency cart nearby. Be prepared to assist with procedures like a stat CT scan or adjustment of therapies.
- 3Ongoing Monitoring & Collaborative Care• Anticipate orders for: Stat ABG, CBC, comprehensive metabolic panel (including sodium, glucose, BUN, creatinine, ammonia), and possibly a head CT.
• Reassess neurological status every 5-15 minutes until the cause is identified and treated.
• Implement safety measures: Apply soft wrist restraints per protocol to prevent self-extubation, ensure the bed alarm is on, and consider a sitter if available.
Patient Safety and Precautions:
• Do NOT automatically increase sedation to control agitation without assessing the cause. Sedation could mask the neurological decline.
• Caution with Restraints: Use only as a last resort to prevent immediate harm, document rationale, and follow hospital policy for frequent neurovascular checks of restrained limbs.
• Medication Safety: If new medications are ordered (e.g., Mannitol for suspected increased ICP), verify dose, indication, and monitor for side effects like electrolyte shifts.
Nursing Procedure & Medication Flow
Procedure: Rapid Neurological Assessment in ICU- 1StimulusUse voice, then gentle tactile stimulus (shake shoulder). Use painful stimulus (e.g., trapezius pinch) only if no response to lighter stimuli.
- 2GCS Scoring• Eyes (1-4): 4=Spontaneously, 3=To voice, 2=To pain, 1=None.
• Verbal (1-5): In intubated patients, score as "T" (tube), but document best response (e.g., nods, mouthing words).
• Motor (1-6): 6=Obeys commands, 5=Localizes to pain, 4=Withdraws from pain, 3=Abnormal flexion (decorticate), 2=Abnormal extension (decerebrate), 1=None.
- 3PupilsUse a penlight. Document size in mm, shape, equality, and reactivity to light (brisk, sluggish, fixed).
- 4DocumentationChart findings precisely, using quotes for patient responses. Note time of change and all actions taken.
A Word from Your Senior Nurse: "In the high-stakes environment of the ICU, you are the patient's constant guardian. A machine can monitor numbers, but you interpret what they mean in the context of the whole person. That moment when you recognize a subtle change—like a shift from calm restlessness to purposeful agitation—is where nursing judgment saves lives. On the NCLEX, they are testing your ability to think like this nurse. Don't just look for the 'sickest' number; look for the finding that signals the system is losing control. Trust your ABCs, trust your neuro check, and never hesitate to escalate. That vigilance is the heart of critical care nursing."
