Lab Values Quiz for Nursing Students
Practice common normal lab values, test your recall, and review a quick nursing lab values reference for NCLEX prep.
What is the normal range for Partial Pressure of O₂ (PaO₂)?
Why lab values matter in nursing school and NCLEX prep
Lab values are one of the most commonly tested topics on the NCLEX — and one of the areas where students lose the most points. Knowing normal ranges is not enough. You need to recognize abnormal values quickly, connect them to clinical situations, and prioritize your nursing response.
Active recall practice — quizzing yourself rather than passively rereading — is one of the most effective ways to memorize lab values. NurseZee's lab values quiz generates randomized questions across electrolytes, CBC, renal, coagulation, ABG, and cardiac labs, with explanations that teach you why each value matters, not just what the number is.
The Quick Reference section gives you a searchable, organized lab values study guide you can review anytime. Use both modes together: quiz to test, reference to reinforce.
