What You'll Learn
Pharmacology is a crucial topic in the NCLEX-PN exam, as it covers the knowledge and skills required to safely and effectively administer medications to patients. This section evaluates a nurse's understanding of drug classifications, mechanisms of action, adverse effects, contraindications, and dosage calculations. Mastering pharmacology is essential for providing high-quality, evidence-based nursing care and ensuring positive patient outcomes.
Key Concepts
Pharmacokinetics
The study of how the body affects a drug, including absorption, distribution, metabolism, and excretion.
Pharmacodynamics
The study of how a drug affects the body, including its mechanism of action, receptor binding, and physiological effects.
Drug Classifications
The grouping of drugs based on their therapeutic uses, chemical structures, or mechanisms of action (e.g., antibiotics, analgesics, antihypertensives).
Adverse Drug Reactions
Unwanted or harmful effects that occur with the use of a drug, including side effects, allergic reactions, and drug interactions.
Therapeutic Index
The ratio of the minimum toxic dose to the minimum effective dose, which indicates a drug's safety margin.
Common Mistakes to Avoid
- Failing to consider drug interactions when administering multiple medications to a patient
- Overlooking contraindications and precautions when selecting appropriate drugs for a patient's condition
- Inaccurate dosage calculations, leading to over- or under-dosing of medications
- Lack of understanding of how a drug's pharmacokinetics and pharmacodynamics affect its therapeutic effects and adverse reactions
- Inadequate patient education about the proper use, storage, and potential side effects of prescribed medications
