NCLEX Week 1 Prep Q&A (80+ Questions) – Electrolytes, Lab Values, Fluid Imbalances

This expert-verified NCLEX prep document for Week 1 contains over 80 essential questions and answers focused on high-yield topics in fluid and electrolyte balance, acid-base regulation, and lab value interpretation—key areas frequently tested on the NCLEX-RN. Tailored for nursing students preparing for licensure or exams, this guide offers concise facts and clinical reasoning cues that are crucial for safe and effective practice. The document covers core electrolytes (sodium, potassium, calcium, magnesium, phosphorus, chloride), including normal ranges, causes of hypo- and hyper-conditions, hallmark signs and symptoms (e.g., Chvostek’s, Trousseau’s, ECG changes), and nursing interventions such as fluid therapy, replacement protocols, medication administration (e.g., diuretics, calcium gluconate, Kayexalate), and dietary considerations. In addition, students will find values and clinical implications of albumin, BUN, creatinine, and their connection to liver, kidney, and nutritional status. Each entry includes pathophysiological associations (renal failure, Addison's, Cushing’s, dehydration, SIADH), reinforcing testable cause-effect logic essential for NCLEX-style questions. This guide is ideal for: Students in BSN and ABSN programs NCLEX-RN and NCLEX-PN candidates Fundamentals of Nursing and Med-Surg review Clinical skills labs and ATI/HESI prep Whether you're brushing up on lab interpretation, fluid shifts, or metabolic markers, this document gives you a fast and reliable foundation to boost retention and exam performance.
