Infection-control precautions: what am I still missing?

The most useful starting point is transmission route, the barrier that interrupts it, and safe transport. If that is not clear, slow down before comparing the answer choices.

I would keep the practice narrow: connect each precaution to the route it is designed to block. That gives you something observable to review after the set.

A common trap is memorizing disease lists without understanding how exposure occurs. Naming that pattern before practice can make it easier to catch in the moment.

Try explaining the decision out loud in one sentence. The explanation should connect directly to transmission route, the barrier that interrupts it, and safe transport.

I would bring this to RN review with one example where the framework worked and one where it still felt ambiguous.
