The CPN (Certified Pediatric Nurse) is a nursing certification awarded by PNCB.
PNCB publishes the official exam outline, eligibility rules and fees — see PNCB's official page before you book.
In our 1060-card CPN deck the heaviest topics are Pathology (31%), Management (24%), Assessment (17%) — that is how this deck is weighted, not the official blueprint, so use it to plan practice and check PNCB's exam outline for the real weighting. This guide shows where the material gets hardest, which topics to practise first, and a 5-step plan built on active recall.

Our CPN cards carry difficulty ratings. The spread tells you how much of the deck is quick recall versus genuinely demanding:

These are genuine cards from the heaviest-weighted topics above. Answer each one before you reveal it — that is what active recall means in practice.
A 10-year-old with suspected coarctation of the aorta is admitted. Where should the nurse prioritize blood pressure measurements to assist in confirming this diagnosis?
Show answer →Measure BP in all four extremities (both upper and both lower). Rationale: In coarctation of the aorta, BP will be significantly higher in the upper extremities than in the lower extremities (a gradient >20 mmHg is diagnostic). You may also find bounding pulses in the arms and weak or absent femoral pulses. Exam Tip: PNCB focuses on the clinical application of vitals. Discrepancies between limb BPs are a classic indicator of obstructive cardiac lesions.
During a well-child visit, the nurse notes the caregiver has difficulty filling out intake forms. Which screening approach is most effective for assessing health literacy in this pediatric setting?
Show answer →Use the Newest Vital Sign (NVS) tool or a single-item screener like How confident are you filling out medical forms? Rationale: Health literacy is a primary SDOH. Low literacy is linked to medication errors and poor outcomes. Clinical Pearl: Use Plain Language and the Teach-Back method regardless of screening results (Universal Precautions for Health Literacy). Avoid assuming literacy based on educational level or verbal fluency. PNCB focuses on the nurse's responsibility to ensure the caregiver understands the plan of care.
A 4-year-old child is being evaluated for dehydration. Using the PALS formula for the lower limit of acceptable systolic blood pressure (5th percentile), what is the minimum SBP for this child?
Show answer →Formula for ages 1-10 years: 70 + (2 x age in years). For a 4-year-old: 70 + (2 x 4) = 78 mmHg. Exam Strategy: Hypotension is a late sign of shock in pediatrics. PNCB expects you to recognize that a child can be in compensated shock with a normal BP. The 70 + 2n rule is a high-yield calculation for identifying the threshold of decompensation.

These 3 topics alone account for roughly 72% of our 1060-card CPN deck. Time spent here pays off more than anywhere else.
Answer questions before flipping to the answer — that struggle is what builds retention. Start with the 30 free CPN cards, then work through the full deck one category at a time.
After a full pass, re-drill only the cards you missed. Small categories are quick wins — closing a weak topic can be an afternoon's work.
Our deck rates 530 cards as hard. If those feel comfortable in your final two weeks, you are studying above test level.
