NURS 5315 Obesity 2026/2027: 42 Exam Questions & Answers | Leptin, Ghrelin, GLP-1, Metabolism & Obesity Pathophysiology

This NURS 5315 Obesity 2026/2027 exam preparation document contains 42 multiple-choice questions with correct answers and detailed rationales covering the physiological, hormonal, neurological, metabolic, genetic, environmental, and behavioral mechanisms associated with obesity. The material begins with energy balance and progresses through hypothalamic appetite regulation, orexigenic and anorexigenic signaling, basal metabolic rate, physical activity, gut hormones, adipose tissue, metabolic risk, and clinical obesity scenarios. The uploaded document does not identify a university or institution, so “University Not Specified” is used rather than attributing the material to an unsupported institution. NURS 5315 Obesity 2026 A central focus is the neuroendocrine regulation of hunger, satiety, and body weight. Questions address the hypothalamus, orexigenic neurons, food-reward pathways, dopamine and the nucleus accumbens, alongside major appetite-regulating hormones such as leptin, ghrelin, peptide YY (PYY), GLP-1, insulin, adiponectin, orexin, and endocannabinoids. The document specifically reviews ghrelin as an appetite-promoting hormone primarily produced by the stomach and leptin as an adipose-derived signal involved in longer-term energy regulation. These themes are consistent with Endotext's discussion of gut-brain signaling and the roles of leptin, ghrelin, GLP-1 and PYY in energy homeostasis and appetite regulation. NCBI The document provides extensive practice on leptin signaling and leptin resistance, including elevated circulating leptin in obesity, impaired responsiveness to leptin, appetite regulation, inflammation, free fatty acids, and metabolic dysfunction. It also examines adiponectin and its relationship with insulin sensitivity and lipid metabolism. Endotext similarly describes leptin as a hormone secreted primarily by white adipose tissue and notes that obesity with leptin resistance is generally associated with increased leptin, while lower adiponectin levels in obesity are associated with insulin resistance and other cardiometabolic abnormalities. NCBI Students will also review GLP-1 physiology and pharmacology, including insulin secretion, satiety, gastric emptying, and semaglutide as a GLP-1 receptor agonist. The questions connect these mechanisms to clinical scenarios involving obesity and type 2 diabetes, including early satiety and gastrointestinal effects after GLP-1 receptor activation. The supporting physiology is described in Endotext, which discusses GLP-1 as a nutrient-responsive gut hormone that promotes satiety, reduces food intake, and can slow gastric emptying. NCBI Additional topics include white versus brown adipose tissue, thermogenesis, basal metabolic rate, muscle mass, physical activity, gut microbiota, genetic predisposition, Prader-Willi syndrome, environmental and socioeconomic influences, chronic stress and cortisol, insulin resistance, visceral versus peripheral fat distribution, and metabolic syndrome risk. The final portion applies these concepts through patient-based questions involving elevated ghrelin, leptin resistance, semaglutide, endocannabinoid signaling, low adiponectin, chronic stress, and visceral obesity. NURS 5315 Obesity 2026 Broader peer-reviewed literature likewise describes obesity as multifactorial, involving interactions among genetics, inflammation, insulin resistance, the gut microbiome, hormones, central neurotransmitters, and peripheral metabolic signals. PubMed Relevant students: This resource is particularly relevant for NURS 5315 students, nursing students, advanced nursing students, nurse practitioner students, pathophysiology students, endocrinology students, and other health-sciences students reviewing obesity physiology and metabolic regulation. It can be used for exam preparation, self-testing, active recall, revision of obesity-related hormones, and practice applying physiological concepts to clinical scenarios.
