How many questions are on the test?
You will face 175 total questions. Out of these, 150 are scored and count toward your final result. The remaining 25 are unscored pretest items used to evaluate future test material.
How much time do I have to finish?
You get exactly 180 minutes to complete the test. This gives you roughly one minute per question.
Is the test computer-adaptive like the NCLEX?
No. It is a fixed-form assessment. Every candidate answers the exact same number of questions regardless of how many they get right or wrong.
What topics are covered?
The content is divided into four official domains. Assessment makes up 35% (53 items) and Planning and Management covers 33% (50 items). Health Promotion accounts for 23% (34 items), while Professional Responsibilities makes up the final 9% (13 items).
What is the passing score?
The exact passing score is not a simple percentage. For details on how the scaled score is calculated, check the PNCB official handbook.
What is the pass rate?
The first-time pass rate was roughly 76–77% in 2022–2023. In 2021, the first-time pass rate was about 78%.
Are there different question types?
The test uses standard multiple-choice items. For specific details on alternative item formats or exhibits, refer to the PNCB candidate manual.
How should I study for this format?
Focus heavily on Assessment and Planning and Management, as they make up 68% of your score. You can build your stamina by using our 2200+ practice questions under timed conditions.
Can I take breaks during the 180 minutes?
The clock does not stop if you take a break. For specific testing center rules regarding restroom breaks, review the official PNCB guidelines.
What happens to the 25 unscored questions?
They are mixed randomly throughout your session. You will not know which items are scored and which are unscored. Treat every item as if it counts.

What the questions actually look like

The format is one thing; the questions are another. Here are three realistic examples. The app has 2,200+, timed and scored.

Question 1

A nurse applies a wrap-around pulse oximeter tightly to a toddler's great toe using circumferential medical tape. The monitor shows a falsely low SpO2 with a bounding waveform.

Why C is the answer

Applying the sensor too tightly causes localized venous congestion, which the oximeter misinterprets as arterial pulsations. This creates a bounding waveform but artificially lowers the SpO2 reading. Loosening the tape restores normal capillary flow and eliminates the artifact. Elevating the foot does not relieve the localized mechanical constriction caused by the tape. Changing the site is unnecessary if the current site is simply wrapped too tightly. Modern pulse oximeters do not require manual calibration for individual sensors.

🔑 Key takeaway

Applying an oximeter probe too tightly creates venous pulsations that falsely lower the SpO2 reading.

Question 2

During a routine visit, a 13-year-old completes the PHQ-9A. The adolescent has a total score of 4 but indicates a positive response to question 9 regarding thoughts of being better off dead. How should the nurse proceed?

Why A is the answer

A positive response on the ninth question indicates potential suicidal ideation and requires an immediate safety assessment to determine the risk level. Even with a low total score indicating minimal depression, safety is the priority. Reassuring the parent ignores the suicide risk. Referring for severe depression is incorrect because the total score is low. Prescribing medication is not indicated for a score of four and skips the necessary risk evaluation.

🔑 Key takeaway

Any positive response to the suicidality item requires immediate safety assessment regardless of total score.

Question 3

An 8-year-old with a well-controlled seizure disorder has an Individualized Healthcare Plan (IHP), but the teacher refuses to administer rescue medication on field trips due to the absence of an IEP. How should the nurse resolve this barrier?

Why C is the answer

While an Individualized Healthcare Plan (IHP) outlines clinical care, incorporating it into a Section 504 Plan provides federal legal protection, ensuring the school must accommodate the student on field trips without requiring an IEP. Explaining that an IEP is legally required is incorrect because IEPs are reserved for students requiring specialized academic instruction, which a well-controlled seizure disorder does not necessitate. Requiring a parent to attend all field trips violates the student's right to equal access and places an unfair burden on the family. Filing a formal complaint does not immediately solve the systemic accommodation issue for the upcoming trip.

🔑 Key takeaway

Integrating an IHP into a Section 504 plan provides federal legal enforcement for school accommodations.
