CPR retraining is MOST effective when:

• A. is self-paced and brief
• B. is delivered by computer
• C. occurs every 24 months
• D. involves hands-on practice

Answer: (B)

Hands-on practice is essential because CPR is a psychomotor skill that requires precise, real-world technique. Rehearsing chest compressions and ventilations on a manikin gives learners the tactile feedback needed to achieve the correct depth, rate, and full chest recoil, which are hard to perfect through reading or watching simulations alone. When students practice with feedback from an instructor or a real-time monitoring system, they can correct errors, build muscle memory, and perform more confidently under stress. While computer-based or self-paced modules can reinforce knowledge, they don’t provide the hands-on rehearsal and immediate corrective feedback that make retraining most effective. Regular practice that actively involves performing the skill leads to better retention and real-life performance.
