When assigning a nurse to cover the ICU for the day, which nurse is best suited to help the ICU team?

• A. The RN who is orienting to the ED from a medical unit
• B. The RN who frequently functions as charge nurse of the ED
• C. The RN who has floated between the ED and ICU
• D. The RN who is interested in training for the ICU

Answer: (C)

Staffing the ICU with someone who already operates with high-acuity, cross-unit experience helps the team function smoothly and keeps patients safe. The nurse who has floated between the ED and ICU brings practical familiarity with both environments: they know ICU equipment and care standards (ventilator management, vasopressor infusions, central line care), recognize early signs of deterioration, and can communicate effectively with the ICU team and ED staff. This background lets them ramp up quickly, align with ICU workflows, and support the team without a lengthy orientation.

The other options lack that immediate, hands-on critical care readiness. An ED nurse orienting from a medical unit may not have current ICU-specific skills. A nurse who frequently serves as ED charge nurse excels in leadership and coordination but not necessarily in delivering direct critical care. A nurse interested in ICU training shows motivation but needs time and experience before reliably covering critical care shifts.
