10 Essential Topics for CEN Exam

1. Rule of Nines

  • Critical for burn patients.
  • Suggestion: Draw a stickman during the test to remember different zones for burn percentage calculations.
  • Likely to encounter a burn-related question.

2. STEMI Patterns

  • Recognize different STEMI patterns: Inferior, septal, anterior, lateral.
  • Practice with a 4x3 EKG grid to familiarize with lead names and infarct patterns.
  • Expect at least one question on this topic.

3. Organophosphates

  • Remember either "MUDDLES" or "SLUDGE" for organophosphate toxidrome symptoms.
  • Symptoms involve fluids from various orifices; important symptoms include meiosis, urination, diarrhea, lacrimation, excitation, and salivation.

4. Placenta Previa vs. Placental Abruption

  • Differentiate based on pain:
    • Placenta Previa: Painless or low-grade pain.
    • Placental Abruption: Significant pain; prioritize fetus as it may be in distress.

5. Measles vs. Chickenpox

  • Differentiate by:
    • Starting point: Measles (face), Chickenpox (trunk).
    • Appearance: Measles are similar, Chickenpox in various stages.
    • Run together: Measles runs together, Chickenpox does not.

6. Torsion vs. Epididymitis

  • Differentiate by time of onset:
    • Torsion: Sudden onset, ischemic pain, within 4-6 hours.
    • Epididymitis: Gradual onset, infection over a couple of days.

7. Priorities of Care (ABCs)

  • Always revert to ABCs unless there’s massive external hemorrhage.
  • Know when to put circulation first; TNCC emphasizes hemorrhage interventions first if necessary.

8. Nursing Process

  • Remember the process: Assess, Plan, Intervene, Evaluate.
  • The test follows this traditional nursing process.

9. Medication Dosages

  • Generally, the test avoids specific dosages due to variability.
  • Standard pediatric dosing: Epinephrine is 0.01 mg/kg.

10. Pediatric Fluid Resuscitation

  • Standard: 20 ccs per kilogram.
  • Focus on resuscitation, not maintenance fluids in the ER context.

Conclusion

  • These 10 topics are frequently seen on the CEN exam.
  • Study and understand these to potentially secure extra points.
