Prepare for NU150 Exam 1 at Galen College of Nursing with this comprehensive 2026 study guide, featuring 200+ exam-style practice questions with verified answers and detailed explanations covering the foundational principles of pharmacology, medication administration, diabetes management, insulin therapy, and diuretic pharmacology. Designed for first-semester nursing students, this resource strengthens clinical reasoning, medication safety, dosage administration, and nursing interventions while preparing learners for classroom examinations, clinical assessments, and NCLEX-style testing. The questions closely reflect the format and difficulty of NU150 exams, making this an excellent review resource for nursing success. This study guide provides comprehensive coverage of pharmacokinetics, pharmacodynamics, pharmaceutics, drug absorption, distribution, metabolism, excretion (ADME), half-life, adverse drug reactions, cumulative drug effects, drug idiosyncrasies, teratogenic medications, synergistic, additive, and antagonistic drug interactions, medication safety, injection techniques, intradermal (ID), subcutaneous (SQ), intramuscular (IM) administration, insulin preparation, medication calculations, and nursing responsibilities during medication administration. Each verified answer reinforces essential pharmacologic principles required for safe nursing practice and successful examination performance. The guide also offers extensive review of diuretic pharmacology, including loop diuretics, thiazide diuretics, potassium-sparing diuretics, furosemide, hydrochlorothiazide, spironolactone, hypertension, edema, heart failure, electrolyte imbalances, hypokalemia, hyperkalemia, dehydration, sulfa allergies, lithium interactions, ACE inhibitor interactions, potassium-rich foods, aldosterone antagonists, weight monitoring, and nursing assessments related to fluid and electrolyte balance. In addition, students review diabetes mellitus, including Type 1 and Type 2 diabetes, insulin deficiency, insulin resistance, HbA1c interpretation, diabetic ketoacidosis (DKA), hypoglycemia, hyperglycemia, insulin administration, rapid-, short-, intermediate-, and long-acting insulin, insulin onset, peak, and duration, metformin, sulfonylureas, contrast media precautions, glucagon administration, insulin storage, lipodystrophy prevention, and evidence-based diabetes management. Additionally, the study guide integrates clinical nursing scenarios, medication administration principles, patient education, pharmacology review, nursing interventions, laboratory monitoring, therapeutic drug effects, and NCLEX-style critical thinking questions to help students build confidence in both classroom examinations and clinical practice. This study guide is ideal for NU150 students, Galen College of Nursing students, Fundamentals of Nursing students, Pharmacology students, Practical Nursing (PN/LPN) students, Associate Degree Nursing (ADN) students, Bachelor of Science in Nursing (BSN) students, pre-nursing students, Registered Nursing (RN) students, and learners preparing for NCLEX-RN or NCLEX-PN examinations.
