ICP & IUPC Monitoring: Nurse's Role in Advanced Devices

Master intracranial and intrauterine pressure monitoring for the 2026 NCLEX-RN.

What's New in 2026?

New NCLEX expectation: "Monitor and maintain internal monitoring devices (e.g., intracranial pressure monitor, intrauterine pressure catheter)."

The 2026 test plan now includes questions about ICP monitors and IUPCs. However, focus on the nurse's role—not the technical specifications or device mechanics.

Intracranial Pressure (ICP) Monitoring

Normal ICP Values

5-15

mmHg (Normal)

15-20

mmHg (Elevated)

>20

mmHg (Critical)

Nursing Responsibilities with ICP Monitors

✓Monitor readings: Assess ICP values and trends continuously
✓Maintain sterile technique: Prevent infection at insertion site
✓Keep head elevated 30°: Promotes venous drainage and reduces ICP
✓Avoid neck flexion/rotation: Can obstruct venous return
✓Minimize stimulation: Reduce noise, bright lights, unnecessary procedures
✓Report waveform changes: Dampened or absent waveforms indicate malfunction

Red Flags: Immediate Intervention Required

🔴 Dampened or absent waveform
🔴 ICP > 20 mmHg persistently
🔴 Sudden increase in ICP readings
🔴 Signs of infection (fever, purulent drainage, redness)
🔴 CSF leakage from insertion site

Intrauterine Pressure Catheter (IUPC) Monitoring

Normal Uterine Pressure Values

5-25

mmHg (Resting)

30-80

mmHg (Contractions)

200+

mmHg (Tetanic)

Nursing Responsibilities with IUPC

✓Monitor contraction strength & frequency: Assess labor progression
✓Maintain sterile technique: Prevent intrauterine infection
✓Position client: Avoid kinks in catheter tubing
✓Monitor for complications: Uterine perforation, infection, placental abruption
✓Assess fetal response: Monitor FHR for signs of fetal distress

Practice Questions: Advanced Monitoring Devices

Question 1: ICP Waveform Assessment

The nurse is caring for a client with an intracranial pressure (ICP) monitor. Which assessment finding requires immediate intervention?

A. ICP reading of 12 mmHg
B. Dampened waveform on the monitor
C. Client reporting a mild headache
D. Temperature of 37.2°C (99.0°F)

✓ Correct Answer: B

Rationale: A dampened waveform may indicate malfunction or obstruction of the monitoring system, requiring immediate assessment and intervention. Normal ICP is 5-15 mmHg (A is normal). Mild headache (C) may be expected. Temperature (D) is normal.

Question 2: IUPC Monitoring During Labor

A client in active labor has an intrauterine pressure catheter (IUPC) in place. The nurse notes uterine contractions registering 200 mmHg with a frequency of every 2 minutes and minimal relaxation between contractions. Which action should the nurse take first?

A. Continue monitoring as this indicates strong, productive labor
B. Notify the provider immediately as this suggests tetanic contractions
C. Increase oxytocin infusion to augment labor
D. Position the client on her left side to improve placental perfusion
