NURS 3110 Allergic Rhinitis & Common Cold Pharmacology 2026 – 40+ Drug Therapy Exam Questions and Answers | Antihistamines, Decongestants & Cough Medications Review

This comprehensive NURS 3110 pharmacology study guide contains more than 40 exam-focused questions, answers, and medication illustrations covering drugs used for allergic rhinitis, the common cold, cough suppression, and upper respiratory symptom management. The document is specifically designed for nursing students preparing for pharmacology exams, ATI assessments, medical-surgical nursing tests, NCLEX-RN preparation, and respiratory system medication reviews. It provides a structured overview of major drug classifications, mechanisms of action, therapeutic uses, adverse effects, contraindications, and nursing considerations for commonly prescribed respiratory medications. Key pharmacology topics covered include first-generation and second-generation H1 receptor antagonists, mast cell stabilizers, intranasal corticosteroids, nasal decongestants, anticholinergic medications, opioid and nonopioid antitussives, expectorants, and mucolytic agents. Major medications discussed throughout the document include diphenhydramine, chlorpheniramine, dimenhydrinate, promethazine, cetirizine, loratadine, fexofenadine, olopatadine, cromolyn, fluticasone, mometasone, triamcinolone, phenylephrine, pseudoephedrine, oxymetazoline, ipratropium, codeine, hydrocodone, benzonatate, dextromethorphan, guaifenesin, and acetylcysteine. The guide also reviews medication side effects, serious adverse reactions, rebound congestion, respiratory depression, bronchospasm, sedation risks, hypersensitivity reactions, glaucoma precautions, urinary retention concerns, and pediatric growth suppression associated with long-term corticosteroid use. This resource is highly beneficial for BSN students, ADN students, practical nursing (LPN/LVN) students, pharmacology students, respiratory nursing students, nurse practitioner trainees, and healthcare learners who need to strengthen their understanding of respiratory pharmacology and safe medication administration. It is also useful for ATI remediation, NCLEX review, classroom exam preparation, nursing clinical rotations, and quick pharmacology revision before competency testing.
