APPLICATION OF MEDICINAL SUBSTANCES

Abstract

The application of medicinal substances is a fundamental component of nursing and clinical practice that ensures effective prevention, treatment, and management of diseases. It involves the correct selection, dosage calculation, administration routes, and monitoring of drug effects on the human body. Safe and effective medication use requires a deep understanding of pharmacological principles, patient assessment, and adherence to clinical protocols. In modern healthcare systems, nurses play a key role in medication administration, including oral, intravenous, intramuscular, subcutaneous, inhalation, and topical routes. Each method requires specific technical skills, strict adherence to aseptic techniques, and careful observation of patient responses. Incorrect drug administration can lead to serious complications such as toxicity, allergic reactions, or therapeutic failure, highlighting the importance of precision and responsibility in nursing practice.
