Pharmacology

Course Description

NUR3145 – Pharmacology is a 3-credit, 45-contact-hour upper-division nursing course covering the drug therapy a nurse administers, monitors, and teaches. It appears in both prelicensure BSN curricula and RN-to-BSN programs, and is a required course in essentially every Florida baccalaureate nursing program.

The course is built on two foundations. Pharmacokinetics — absorption, distribution, metabolism, and excretion — explains what the body does to a drug. Pharmacodynamics explains what the drug does to the body: receptor interaction, mechanism of action, and dose-response relationships. Everything else follows from these, which is why students who treat the course as memorization struggle and those who learn the mechanisms do not.

From there the course works systematically through the major drug classifications — cardiovascular, respiratory, neurologic, psychiatric, endocrine, anti-infective, analgesic, gastrointestinal, and chemotherapeutic agents — examining for each the mechanism, therapeutic use, adverse effects, contra­indications, interactions, and the specific nursing implications: what to assess before administering, what to monitor after, and what to teach the patient.

Two threads run throughout. Safe medication administration is treated as the practical core of the course, since medication error is among the most common and most preventable sources of patient harm. And lifespan variation — how drug handling differs in neonates, children, pregnancy, and older adults — is integrated rather than isolated, because dosing errors concentrate at the extremes of age.

Offered at approximately 22 Florida institutions, spanning the State University System (FAMU, FAU, FGCU, FIU, FSU, UCF, USF, UWF) and the state colleges awarding the BSN (Daytona State, Florida Gateway, Florida SouthWestern, Hillsborough, Indian River State, Lake-Sumter, Pensacola State, Santa Fe, South Florida State, Seminole State, State College of Florida, Valencia).

Major Topics

Required Topics

• Endocrine agents — insulin and oral antidiabetics, thyroid drugs, and corticosteroids.
• Gastrointestinal agents — acid suppressants, antiemetics, and laxatives.
• Antineoplastic and immune agents — chemotherapy principles, immunosuppressants, and safe handling.
• Lifespan considerations — pediatric, pregnancy and lactation, and geriatric pharmacology including polypharmacy and Beers criteria.

Optional Topics

• Pharmacogenomics and precision medicine.
• Complementary and alternative therapies.
• Antimicrobial stewardship.
• Substance use disorder and medication-assisted treatment.
• Emergency and critical care medications.
• Medication reconciliation and transitions of care.

Resources & Tools

• Pharmacology and the Nursing Process (Lilley, Collins & Snyder), Elsevier — among the most widely adopted texts.
• Pharmacology: A Patient-Centered Nursing Process Approach (McCuistion et al.), Elsevier.
• Focus on Nursing Pharmacology (Karch), Wolters Kluwer — a common alternative.
• Drug references — Davis's Drug Guide, Lexicomp, Micromedex, and Epocrates; students are expected to use an authoritative reference rather than general web search.
• Institute for Safe Medication Practices (ISMP) — high-alert medication lists and error-prevention guidance.
• ATI or HESI pharmacology modules and practice assessments, used by most Florida programs.
• Florida Board of Nursing and Chapter 464, F.S. — scope of practice for medication administration.
• Florida PDMP (E-FORCSE) — the state prescription drug monitoring program, relevant to controlled substance content.
• Simulation laboratory with medication administration systems and barcode scanning where available.

Career Pathways

Pharmacology is a required competency across nursing rather than a specialization in itself.

• Registered Nurse (SOC 29-1141) — medication administration is core to the role in every setting.
• Critical Care, Emergency, and Perioperative Nursing — areas where pharmacologic knowledge is most heavily exercised.
• Oncology Nursing — requires additional chemotherapy certification.
• Nurse Educator — teaching pharmacology in prelicensure programs.
• Advanced Practice Registered Nurse — nurse practitioners hold prescriptive authority in Florida, and graduate pharmacology builds directly on this course.
• Clinical Research Nurse and Pharmaceutical Industry roles — clinical trials and medical science liaison work.

Florida employers include AdventHealth, Orlando Health, BayCare, Baptist Health, Tampa General, Memorial Healthcare, Lee Health, and the VA system.

Special Information

Prerequisites

Prerequisites vary and are program-driven; verify locally. Admission to the nursing program is the universal requirement. Beyond that, institutions commonly require anatomy and physiology (BSC2085/BSC2086), microbiology (MCB2010), and often chemistry, with a minimum grade of C. Seminole State lists NUR3825 as a prerequisite or corequisite. Prelicensure programs typically place this course in the first or second nursing semester; RN-to-BSN programs may waive or substitute it for students whose ADN covered the content.

Course-title variation across Florida

This SCNS number carries a wide range of local titles: Pharmacology, Pharmacology for Nursing Practice (FAMU), Pharmacology in Nursing Practice (USF), Pharmacologic Basis (FIU), and Pharmacology and Alternative Therapeutics (Florida SouthWestern) among them. Under SCNS the courses are equivalent at the same level regardless of title, but the FSW title signals a genuine difference in emphasis — that section integrates complementary and nutritional therapies more substantially than most. Students comparing programs should read the description, not just the title.

Position in the curriculum

Pharmacology is foundational to medical-surgical nursing and every subsequent clinical course. Programs generally require it early and often require a minimum grade to progress. It is also heavily represented on the NCLEX-RN, where pharmacological and parenteral therapies constitute a substantial content category.

Dosage calculation competency

Many Florida nursing programs require a separate dosage calculation examination with a high passing threshold — frequently 90% or above, sometimes 100% — independent of the course grade, and often with a limited number of attempts. Students should confirm their program's policy early, because failing it can halt progression regardless of overall performance.

Difficulty and study approach

Pharmacology is widely regarded as one of the hardest courses in a nursing curriculum, and the reason is volume: hundreds of drugs, each with mechanisms, effects, and nursing implications. The students who do well generally learn by drug class rather than individual drug — understanding what beta blockers do as a class makes the individual agents largely predictable — and connect each drug back to the underlying pathophysiology. Rote memorization of drug lists scales poorly and is the most common failure pattern. Plan sustained weekly study rather than pre-exam cramming.
