Six ways a practice question fails, and how we catch them

Each question is tied to one section of its exam's current outline and is filed under that section; the study guide works through a few of each section's questions. Two exams in the same field get a firmer rule: the hospice RN and advanced practice exams overlap, so each topic gets written up on one of them. Dosing decisions that fall to an APRN are written up on the advanced practice pages and nursing care on the RN pages. Both exams can ask about opioids, but on this site the same scenario is never used twice.

Every wrong option is then argued for as if it were the key. If a reasonable case survives, the option or the stem is rewritten until it does not. Questions that ask for the first, best or priority action get the closest look, because that is where two answers can both look right. A rationale that calls a wrong option "also reasonable" counts as a fault, not as nuance.

Under each option there is a short note written for that option alone: why it is right, or which common misunderstanding makes it look right. Notes are checked against their own option, so a rationale cannot drift to the option next to it, and none of them borrows numbers that the source documents do not support.

Before publication each question is compared with a large body of practice questions already in circulation, both by wording and by idea: the same clinical scenario leading to the same key counts as a copy even when no sentence matches. Matches are replaced, and the replacement is checked the same way.

A separate review, run independently of the work that prepared the question, reads the question, its key and every note once more. Anything it flags is fixed or replaced, and the change goes back through the steps above. Fact pages are reviewed against their source documents in the same pass.
