NUR 138 Diabetes Management, Insulin Therapy & GI Pharmacology Final Exam Questions and Answers (100+ Q&A) | Metformin, Insulin Types, GERD, PPIs & Antidiabetic Drugs | Nursing Pharmacology

This comprehensive NUR 138 pharmacology study guide contains more than 100 detailed exam questions and correct answers focused on diabetes management, insulin therapy, antidiabetic medications, gastrointestinal pharmacology, GERD treatment, proton pump inhibitors (PPIs), antacids, and nursing medication safety commonly tested on final exams and NCLEX-style assessments. The material provides extensive review content covering insulin classifications, metformin, sulfonylureas, glinides, thiazolidinediones, alpha-glucosidase inhibitors, incretin-based therapies, acid-reducing medications, ulcer treatments, and evidence-based nursing interventions for endocrine and gastrointestinal disorders. The document offers nursing students an in-depth understanding of blood glucose regulation, insulin pharmacokinetics, diabetes medication administration, and management of hypoglycemia and hyperglycemia. Key concepts include glucose metabolism, glycogenolysis, glucagon function, exogenous insulin therapy, rapid-acting insulin timing, IV administration of short-acting insulin, insulin glargine characteristics, NPH insulin preparation, and diabetic medication safety. Students will also review essential nursing considerations related to metformin use, contrast dye precautions, hypoglycemia monitoring, insulin sensitivity, liver glucose production, and adverse effects associated with oral antidiabetic medications. Special emphasis is placed on pharmacologic management of gastrointestinal disorders including GERD, peptic ulcer disease, acid reflux, and gastric mucosal protection. The study guide reviews antacids, H2 receptor antagonists, proton pump inhibitors, sucralfate, misoprostol, simethicone, and medication interactions affecting acid suppression therapy. Nursing priorities such as timing of medication administration, prevention of drug interactions, osteoporosis risk from long-term PPI use, management of hypotension during IV cimetidine therapy, and contraindications for medications like misoprostol during pregnancy are presented using NCLEX-style question-and-answer formatting to strengthen medication safety and clinical judgment skills. Additional topics include Barrett esophagus, chronic GERD complications, thyroid tumor warnings associated with liraglutide, renal precautions with magnesium hydroxide, and nursing interventions related to antacid use and ulcer prevention. The guide also explains mechanisms of action for major diabetic and gastrointestinal drug classes while reinforcing patient teaching, adherence strategies, and monitoring responsibilities required for safe nursing care. The concepts covered in this resource align with evidence-based pharmacology and nursing practice standards discussed in authoritative references including Lehne’s Pharmacology for Nursing Care, Pharmacology and the Nursing Process by Lilley, Harrington & Snyder, American Diabetes Association (ADA) Standards of Care, and American College of Gastroenterology (ACG) guidelines for GERD management. Additional support for the pharmacologic principles presented can be found in peer-reviewed journals such as the Journal of Clinical Nursing, Diabetes Care, and the American Journal of Nursing, which emphasize medication safety, patient education, glycemic control, and evidence-based management of gastrointestinal disorders. This study document is highly relevant for NUR 138 students, pharmacology nursing students, BSN students, RN candidates, practical nursing students, NCLEX preparation learners, medical-surgical nursing students, endocrinology nursing students, healthcare trainees, clinical placement students, and nursing professionals preparing for pharmacology exams, diabetes management assessments, or medication administration competency evaluations.
