Infection Control Practice Test

Welcome to the Infection Control practice page for the Certified Nursing Assistant (CNA) exam. This drill is published by ExamEdge Prep against the official Prometric / state DOH blueprint and covers the Infection Control knowledge area in detail.

The exam runs 60-70 written + skills demo and requires ~75% per state to pass. Most candidates report needing 60–120 hours of focused review across the entire blueprint; this page contributes roughly five to seven percent of that prep time. Working the Infection Control objectives in isolation is the proven approach used by veteran tutors — CNA questions in this knowledge area mix recognition (definitions, components, classifications) with applied scenarios that require you to weigh competing options under realistic time pressure. If you are pairing this drill with a textbook or LMS, log your incorrect answers in a single-row spreadsheet so the patterns surface after two or three sittings.

What’s tested in Infection Control

The Infection Control domain on the CNA carries one of the heaviest weightings on the published blueprint. Expect to see questions that test (1) terminology and core definitions, (2) procedural sequencing — what to do first, second, and last in a multi-step process — and (3) judgment calls where two answer choices look defensible but only one is the best answer for the role being tested. The Prometric / state DOH emphasizes scenario-based items that simulate the day-to-day decisions of a credentialed practitioner; rote memorization will not be enough above the cut score.

Common pitfalls candidates fall into on this section include misreading qualifiers ("always," "never," "first," "primarily"), assuming generic best practice instead of the practice the exam blueprint specifically endorses, and burning time on items they should flag and return to. The questions on this page have been written with those traps embedded so you can see them coming on test day.

How to use this Infection Control practice set

Work each question without looking at the explanation. Mark the items you are unsure of even when you guess correctly — those are the high-leverage ones to study. After submitting, review every explanation, even on the items you got right; the rationale often introduces an exam-relevant nuance that will appear on a future drill in this series. Then move on to the next variant in the Infection Control sequence and repeat with a 24-hour gap so spaced repetition can do its work.

The investment to credential, including the CNA exam fee, is non-trivial. Most candidates spend $80-$130 USD plus study materials, application fees, fingerprinting, background checks, and the opportunity cost of study time. A retake doubles the financial cost and adds 30–90 days of delay before you can sit again. The honest payoff for thirty extra hours of high-quality drill is a first-attempt pass; this page is a piece of that thirty hours.

Recommended next steps

After completing this practice variant, move to a different domain on the same exam to build breadth, then return to Infection Control the following day for retention. The full exam outline for the CNA credential is published by Prometric / state DOH; you can download the candidate handbook directly from the agency. ExamEdge Prep tracks the published outline and updates these drills whenever the blueprint changes — typically every 36 months for IT certifications and every five to seven years for state licensing exams.
