What’s on the CPN cheat sheet
- Assessment (35%) — age-based vital signs, growth parameters and milestones, the developmental approach and Pediatric Assessment Triangle, pain scales by age, and classic body-system findings — the largest domain.
- Planning & Management (33%) — weight-based dosing and safe-dose checks, respiratory, GI, cardiac, neuro, endocrine and heme/onc priorities, dehydration and fluids, and family-centered care.
- Health Promotion (23%) — growth and development frameworks, anticipatory guidance and injury prevention, nutrition and feeding, and the CDC immunization schedule.
- Professional Responsibilities (9%) — advocacy, ethical and legal practice including mandatory reporting and consent, and interdisciplinary collaboration and delegation.
How to use it in your final week
- Front-load Assessment (35%) and Planning & Management (33%) — together about two-thirds of the scored items, so give the vital-signs table, developmental approach, and body-system findings the most passes.
- Drill the age-based vital-sign ranges and the immunization timeline until recall is instant — these are the facts that flip fastest under a 3-hour clock.
- Rehearse a weight-based dosing check: convert pounds to kilograms (lb ÷ 2.2), calculate mg/kg, and confirm the dose sits inside the safe range before you'd ever give it.
- Read the whole sheet the morning of the exam, then pair it with one short timed practice block so your pacing and your recall peak together.
The cheat sheet is your review layer — your CPN practice test drives the exam-readiness ring at the top of this page. Download it, review, then take a full practice exam (or drill with the study guide and flashcards) to see where you stand.
CPN cheat sheet FAQ
Yes — the CPN cheat sheet downloads as a PDF at no cost and with no sign-up. It sits alongside Career Employer's free CPN practice test, study guide, and flashcards, so your whole pediatric-nursing review lives in one place.
It compresses the highest-yield pediatric facts into a quick reference organized by the four PNCB domains: age-based vital signs, developmental milestones, the immunization schedule, weight-based dosing, and the classic body-system findings (croup vs. epiglottitis, bulging fontanelle, currant-jelly stools). Everything is grouped the way the PNCB weights the exam so you review in blueprint order.
No — the sheet is a condensed cram and review layer, not a full course. You still need a scaled score of 400 (on a 200–800 scale), so use the sheet to lock in facts and the practice test to build the margin the criterion-referenced standard rewards.
It is built from the current PNCB CPN Detailed Content Outline and CDC pediatric schedules, and we review it against those official sources regularly. Pediatric immunization dates and PNCB fees change, so confirm anything time-sensitive on pncb.org and cdc.gov.
