Infection Control practice questions
How infection spreads and how the exam asks about stopping it.
Infection control is about how germs spread and what a nursing assistant does to stop them. The written exam asks about the chain of infection, hand hygiene, personal protective equipment, standard precautions and the additional precautions used for residents who have a known infection. It also asks about how to handle linen, trash and equipment so that infection does not pass from one person to another. The exam treats these as principles: why a step is done, when it is done, and in what order. Hand hygiene is the single most-tested idea in this domain, and the questions here reflect that. The questions are written for this site and the full explanation for every one is free. Plain English is the rule, because a candidate whose first language is not English should not have to guess what the question means. Nothing on this site is care instruction — the explanations say what the exam expects, not how to treat a person.

What this topic covers
These are the concepts behind the questions in this bank.
The 23 questions above cover the concepts this topic is organised around. Answer each one, read the full explanation, and note what you missed. The result groups nothing into a score — it counts what you got right by topic, which is all an uncalibrated question bank can truthfully tell anyone.
Where these eight topics come from. They are this site's own organisation of the material, chosen so that related questions sit together. They are not the official content areas of any state's written exam, and no mapping between the two is claimed here — that mapping has not been verified against the published candidate handbooks, so it is not stated. Your state's handbook is the authority on how its exam is divided and weighted; how to find yours is set out separately.
