PHM 104 Final Exam Study Guide (2026) | 500+ Practice Questions & Correct Answers | Pharmacology, Respiratory Drugs, Endocrine Pharmacology, Psychiatry & Diabetes Medications

Prepare for the PHM 104 Final Exam with this comprehensive 2026 study guide, featuring 500+ exam-style practice questions with correct answers and detailed rationales covering the essential principles of cardiovascular pharmacology, respiratory pharmacology, endocrine pharmacology, psychiatric medications, diabetes management, and autonomic pharmacology. Designed for pharmacy, pharmacology, nursing, physician assistant, and other health sciences students, this resource strengthens drug classification, mechanisms of action, therapeutic uses, adverse effects, contraindications, and clinical decision-making while preparing learners for final examinations, professional coursework, and board-style assessments. The questions closely reflect the scope and complexity of PHM 104 examinations, making this guide an excellent review resource for mastering core pharmacologic concepts. This study guide provides comprehensive coverage of respiratory and pulmonary pharmacology, including pulmonary arterial hypertension (PAH) therapies, prostacyclin derivatives, endothelin receptor antagonists, soluble guanylate cyclase stimulators, phosphodiesterase-5 (PDE5) inhibitors, cystic fibrosis medications, CFTR modulators, chronic obstructive pulmonary disease (COPD) pharmacotherapy, phosphodiesterase-4 inhibitors, anticholinergics, beta-2 agonists (SABA, LABA, and ultra-LABA), inhaled corticosteroids, antitussives, mucolytics, antihistamines, alpha-adrenergic agonists, bronchodilators, leukotriene-related therapies, magnesium, omalizumab, terbutaline, cough suppression, allergic rhinitis, motion sickness, nasal decongestants, asthma management, respiratory inflammation, and pulmonary drug mechanisms of action. Each verified answer reinforces medication classifications, therapeutic applications, adverse reactions, and evidence-based pharmacologic management of respiratory diseases. The guide also delivers extensive review of endocrine, metabolic, musculoskeletal, and psychiatric pharmacology, including insulin therapy, rapid-, short-, intermediate-, and long-acting insulin preparations, oral antihyperglycemic agents, metformin, sulfonylureas, meglitinides, GLP-1 receptor agonists, DPP-4 inhibitors, SGLT-2 inhibitors, thiazolidinediones (TZDs), diabetes mellitus pathophysiology, diabetic pharmacotherapy, hypothyroidism, hyperthyroidism, levothyroxine, methimazole, propylthiouracil, thyroid hormone regulation, osteoporosis medications, bisphosphonates, denosumab, raloxifene, teriparatide, abaloparatide, romosozumab, calcitonin, schizophrenia pharmacotherapy, first- and second-generation antipsychotics, extrapyramidal symptoms (EPS), tardive dyskinesia, depression, selective serotonin reuptake inhibitors (SSRIs), serotonin-norepinephrine reuptake inhibitors (SNRIs), tricyclic antidepressants (TCAs), monoamine oxidase inhibitors (MAOIs), tetracyclic antidepressants (TeCAs), benzodiazepines, hypnotics, sedatives, ADHD medications, stimulants, atomoxetine, bipolar disorder treatment, lithium, anticonvulsants, mood stabilizers, pharmacologic mechanisms, adverse drug reactions, contraindications, and clinical therapeutics. The study guide integrates pharmacodynamics, pharmacokinetics, receptor pharmacology, evidence-based prescribing principles, and examination-focused clinical scenarios to prepare students for academic success and professional healthcare practice. This study guide is ideal for PHM 104 students, pharmacy students, pharmacology students, Doctor of Pharmacy (PharmD) students, nursing students, physician assistant (PA) students, medical students, biomedical sciences students, pharmaceutical sciences students, allied health students, and learners preparing for pharmacology examinations and healthcare professional licensing assessments.
