How many questions are on the test?
You will face 175 total items. Only 150 of these count toward your final score. The remaining 25 are unscored pilot questions.
How much time do I have to finish?
You get exactly 180 minutes to complete the session. This gives you about one minute per item.
Is the test computer-adaptive like the NCLEX?
No. This is a fixed-form assessment. Every candidate answers the exact same number of questions regardless of performance.
What topics are covered?
The content is divided into four official domains. Assessment makes up 35% (53 items) and Planning and Management is 33% (50 items). Health Promotion covers 23% (34 items), while Professional Responsibilities accounts for 9% (13 items).
What score do I need to pass?
We do not have the exact passing threshold. You must check the official candidate handbook from the credentialing body for current scoring details.
What happens if I fail?
Retest policies change frequently. Review the PNCB official handbook for specific waiting periods and reapplication rules.
How much does it cost to take?
Pricing details vary by your membership status. Please consult the Pediatric Nursing Certification Board documentation for the most accurate fee structures.
How can I improve my chances of passing?
Focus your study time heavily on Assessment and Planning and Management, as these two areas make up 68% of your score. Work through our 2200+ practice questions to build your stamina for the three-hour time limit.
Are the unscored questions identified?
No. The 25 pilot items are mixed randomly with the 150 scored items. You must treat every prompt as if it counts.
How do I apply to test?
Application steps and eligibility requirements are managed directly by the board. Refer to the PNCB website and handbook to start your registration.

Judge the difficulty yourself

These are three CPN practice questions at exam difficulty. See where you land. The app has 2,200+, timed and scored.

Question 1

A 12-year-old transgender female has been on puberty-suppressing medications for two years. The nurse recognizes the patient is at increased risk for which complication?

β–Έ Why A is the answer

Prolonged use of GnRH agonists delays the expected pubertal surge in sex steroids, which is critical for normal bone mineral density accrual during early adolescence. Monitoring bone health through lifestyle education and periodic DEXA scans is essential. Option B is incorrect because hyperlipidemia is typically associated with gender-affirming hormones like testosterone, not puberty blockers. Option C is incorrect because a transgender female (assigned male at birth) does not have ovaries. Option D is incorrect because liver toxicity is primarily a risk associated with testosterone therapy, not puberty blockers.

πŸ”‘ Key takeaway

Prolonged use of puberty blockers can delay bone mineral density accrual, requiring routine monitoring.

Question 2

A 16-year-old is admitted with a Glasgow Coma Scale score of 4 after a motor vehicle collision. The patient is ventilator-dependent and hemodynamically unstable.

β–Έ Why A is the answer

Hospitals are mandated to notify the procurement organization of all imminent deaths, typically defined by specific clinical triggers such as a Glasgow Coma Scale of 5 or less in a ventilator-dependent patient. Option A is correct because early notification allows the organization to evaluate suitability before death is declared. Option B is incorrect; the family should not be approached until the patient is formally evaluated. Option C delays necessary evaluation and violates early notification protocols. Option D is premature and does not address the immediate regulatory requirement for procurement organization notification.

πŸ”‘ Key takeaway

Early clinical triggers require hospitals to notify the procurement organization before brain death is formally declared.

Question 3

The nurse is preparing to perform a Finnegan score on a two-day-old neonate exposed to fentanyl. The infant is currently in a brightly lit room with loud alarms sounding nearby and is crying continuously. What is the most appropriate nursing action?

β–Έ Why C is the answer

Finnegan scoring is designed to measure the baseline severity of withdrawal symptoms, but scores can be falsely elevated by external stressors. When an infant is in a brightly lit room with excessive noise, the nurse should first optimize the environment by dimming lights, reducing noise, and attempting to console the infant before finalizing the score. Option C is correct because it ensures the score reflects true withdrawal rather than acute environmental overstimulation. Option A and Option D are incorrect because scoring a highly stimulated infant leads to inaccurate, inflated totals that may trigger unnecessary medications. Option B is incorrect because medication decisions must always be based on accurate, standardized scoring, not situational distress.

πŸ”‘ Key takeaway

Finnegan scoring should reflect the infant's true withdrawal state after optimizing nonpharmacologic environmental interventions.
