The NCLEX uses a Computer Adaptive Testing (CAT) format, which adjusts the difficulty of questions based on the test-taker's ability. The exam covers four main categories: Safe and Effective Care Environment, Health Promotion and Maintenance, Psychosocial Integrity, and Physiological Integrity. The number of questions varies, with a minimum of 75 and a maximum of 265 for the NCLEX-RN, and 85 to 205 questions for the NCLEX-PN.
