RDA Practice Exam – California RDA Test Prep & Free Practice Test (2026)

Instruments used during medical procedures and surgeries pose the greatest risk of transmitting infections due to them coming in contact with blood, body fluids, and tissues. These instruments are called "critical instruments" and require thorough sterilization and disinfection before each use to prevent the spread of infections. The other options, non-critical, semi-critical, and minimal risk instruments, do not come in direct contact with bodily fluids and therefore pose a lower risk of transmitting infections. However, they still require proper cleaning and disinfection to maintain a safe environment for patients.
