PN2005 Practical Nursing Final Exam 2026 – 120 Questions and Answers on Pharmacology, Medication Administration, Cardiovascular Drugs & Nursing Safety

This document contains approximately 120 exam-style questions and verified answers designed to help students prepare for the PN2005 Practical Nursing Final Exam, a pharmacology-focused course commonly taught in practical nursing and vocational nursing programs. The material is presented in a structured question-and-answer format that reviews medication administration principles, drug classifications, pharmacokinetics, cardiovascular medications, central nervous system drugs, endocrine therapies, and nursing safety practices related to medication use. The study material begins with foundational principles of safe medication administration and pharmacological nursing practice. Key concepts include the “Seven Rights of Medication Administration,” which include the right patient, right drug, right dose, right route, right time, right reason, and right documentation. The document also explains the importance of medication documentation in the Medication Administration Record (MAR) and outlines legal requirements for physician orders such as medication name, dose, frequency, and provider signature. Medication safety procedures such as narcotic counts, which must be performed by two licensed nurses during shift changes, are also emphasized to prevent medication diversion and ensure accountability in clinical settings. Another important section focuses on pharmacokinetics and drug metabolism, which describes how the body processes medications through absorption, distribution, metabolism, and excretion. The material highlights factors that influence medication absorption, including route of administration, tissue hydration, temperature, and surface area of application for topical medications. For example, intravenous administration provides the fastest drug absorption because medication enters the bloodstream directly. The document also discusses the “first-pass effect,” a metabolic process that occurs in the liver and can reduce the bioavailability of orally administered drugs. The guide also reviews drug therapy considerations for elderly patients, an important topic in geriatric pharmacology. Age-related physiological changes can alter drug metabolism and increase sensitivity to medications, requiring careful dose adjustments. The document emphasizes the clinical principle “start low and go slow,” which means initiating treatment with a low dose and gradually increasing it to minimize adverse effects and drug toxicity in older adults. A large portion of the document focuses on cardiovascular pharmacology, including medications used to treat hypertension, heart failure, and angina. Drug classes discussed include ACE inhibitors, beta-blockers, calcium channel blockers, angiotensin II receptor blockers, direct vasodilators, and renin inhibitors. For example, beta-blockers reduce heart rate and blood pressure by blocking the effects of epinephrine and norepinephrine on cardiac receptors. ACE inhibitors such as lisinopril, ramipril, and captopril are commonly used antihypertensive medications that reduce blood pressure by preventing the conversion of angiotensin I to angiotensin II. The document also reviews nitrates used in angina treatment and provides patient teaching guidelines such as taking sublingual nitroglycerin every five minutes up to three doses while seeking medical attention if symptoms persist. Another key section covers diuretics and fluid management medications, particularly loop diuretics such as furosemide. These medications promote diuresis by blocking sodium and potassium reabsorption in the kidneys, helping reduce fluid overload in conditions such as heart failure and severe peripheral edema. Nursing considerations discussed include monitoring potassium levels, assessing daily weight, and administering the medication in the morning to prevent nocturia and sleep disruption. The document also includes extensive coverage of central nervous system medications, including antidepressants, anxiolytics, sedatives, and medications used for neurological disorders. Selective serotonin reuptake inhibitors (SSRIs) are described as commonly prescribed medications for anxiety and depression, with important nursing considerations such as monitoring for suicidal ideation or changes in mental status. Benzodiazepines such as diazepam are identified as anxiolytics used to treat anxiety and muscle spasms, while medications like carbidopa-levodopa are used in the treatment of Parkinson’s disease to improve dopamine activity in the brain. The study guide further reviews endocrine and metabolic medications, including insulin therapy for type 1 diabetes and oral antidiabetic agents such as metformin and glyburide for type 2 diabetes. Emergency management of hypoglycemia is also discussed, including the administration of glucagon for patients experiencing severe hypoglycemic episodes. Additional pharmacological concepts include thyroid hormone production and disorders associated with thyroid dysfunction. Another section focuses on anti-infective medications and antimicrobial therapy, explaining the differences between bactericidal and bacteriostatic antibiotics. The document also reviews antifungal medications such as oral nystatin used to treat oral candidiasis (thrush). Patient teaching considerations related to antibiotic therapy and potential drug interactions are also discussed. Additional content reviews analgesics and opioid medications, including their therapeutic uses and common adverse effects such as respiratory depression, sedation, and constipation. The guide emphasizes safe opioid administration practices and patient education to reduce misuse and ensure effective pain management. The material aligns with widely used nursing pharmacology textbooks such as “Pharmacology for Nurses: A Pathophysiologic Approach” by Michael Patrick Adams and Norman Holland and “Lehne’s Pharmacology for Nursing Care”, which are commonly used in practical nursing and medical-surgical nursing education to teach medication therapy and safe drug administration. This document may be useful for courses such as: PN2005 Nursing Pharmacology Practical Nursing Medication Administration Clinical Pharmacology for Nurses Medical-Surgical Nursing Pharmacology Nursing Drug Therapy and Patient Safety It may also benefit students including: Practical Nursing (PN) students Licensed Practical Nurse (LPN) program students Vocational nursing students Medical-surgical nursing students reviewing pharmacology NCLEX-PN preparation students studying medication safety and drug classes Overall, this document serves as a comprehensive pharmacology exam preparation resource that compiles essential nursing medication knowledge, pharmacokinetic principles, cardiovascular drug therapies, endocrine medications, antimicrobial treatments, and safe medication administration practices into structured exam-style questions and answers. It helps nursing students strengthen their understanding of pharmacology concepts required for practical nursing examinations and safe medication management in clinical practice.
