Adult medical-surgical nursing — the physiological-integrity core of the NCLEX-RN. Recognize and respond across the big systems: cardiac (MI, heart failure, dysrhythmias), respiratory (COPD, asthma, chest tubes), renal and fluid-electrolyte balance (the classic K+/Na+/Ca2+ traps), endocrine (diabetes, thyroid, adrenal), GI, neuro (stroke, ICP, seizures), and perioperative care. Each question is a realistic clinical judgment: which finding to report first, which patient to see first, what the abnormal value means. Explanations teach the pathophysiology behind the right call, name the misconception behind the tempting distractor, and end with a portable rule. Original items from the public NCSBN test plan — never real exam questions. Independent study practice; educational only, not medical advice.
• Meets you at your level — never too easy, never too hard.
