Pharmacology and Medication Safety: Nursing Fundamentals Exam 1(2026–2027 Updated) – 30+ Q&A with Verified Answers | Drug Administration, Opioids, & Eye Medications

This comprehensive pharmacology and medication safety study guide is fully updated for the 2026–2027 nursing curriculum. It contains key exam questions with verified answers, covering essential topics for nursing fundamentals including: Six Rights of Medication Administration (right patient, medication, dose, route, time, documentation), additional safety rights (right reason, response, education), high-alert medications (opioids, insulin, anticoagulants – requiring barcode scanning and independent double checks), medication reconciliation (verifying home medications at admission, transfer, discharge), adverse effects (unintended secondary effects at therapeutic doses), side effects vs. toxic effects (toxic effects result from excessive dosing or accumulation), drug interactions (drug-drug, drug-food, drug-herbal), contraindications (conditions making drug use unsafe – glaucoma, pregnancy), weight-based dosing in pediatrics due to immature liver and kidney function, older adult medication considerations (decreased renal/hepatic function, increased sensitivity to CNS depressants), nursing process in pharmacology (assessment, diagnosis, planning, implementation, evaluation), patient education in medication administration (purpose, how to take, side effects, adherence), opioid analgesics (moderate to severe pain – bind to opioid receptors in CNS), common adverse effects of opioids (respiratory depression, sedation, constipation, nausea/vomiting, hypotension), antidote for opioid overdose (naloxone/Narcan), Schedule I controlled substances (no accepted medical use, high abuse potential – heroin, LSD), Schedule II (high abuse potential, accepted medical use, written prescriptions), Schedule IV (example: benzodiazepines – diazepam, lorazepam), antiglaucoma agents (decrease intraocular pressure), mydriatics/cycloplegics (eye exams – dilate pupils), reducing systemic absorption of eye medications (apply pressure to nasolacrimal duct for 1-2 minutes), key considerations for eye medication patient education (correct eye drop technique, full course of therapy, reporting side effects), and opioid administration nursing consideration (assess pain and respiratory rate before administration; hold if RR 12/min). High-yield for nursing fundamentals, pharmacology exams, and NCLEX-RN preparation.
