Chapter 1: The Nursing Process and Drug Therapy

The five-step nursing process—consisting of assessment, human need identification, planning with outcome specification, implementation, and evaluation—provides nurses with a systematic, evidence-based approach to medication management and patient safety. During the assessment phase, nurses gather both subjective data from patient interviews and objective data from physical examination and medical records to establish a comprehensive baseline for drug therapy decisions. Human need statements allow nurses to translate clinical findings into prioritized, patient-centered care goals that extend beyond traditional diagnostic labels. The planning stage involves establishing measurable, realistic outcomes that define both therapeutic efficacy and safety parameters for medication interventions. Implementation encompasses the technical and interpersonal dimensions of nursing care, including accurate medication administration according to established protocols and comprehensive patient education designed to promote understanding, adherence, and prevention of adverse effects. The evaluation phase completes the cyclical process by determining whether interventions achieved desired outcomes and identifying necessary adjustments to the care plan. The chapter emphasizes critical safety competencies, particularly the Nine Rights of medication administration—ensuring correct patient, drug, dose, route, time, documentation, education, evaluation, and response—as fundamental safeguards against medication errors. Understanding the distinction between compliance and adherence reflects modern, patient-centered thinking about medication management. Professional nursing standards, quality improvement initiatives such as QSEN, and evolving assessment frameworks like the Next Generation NCLEX shape contemporary pharmacology practice by requiring nurses to integrate clinical reasoning, evidence-based practice, and interprofessional collaboration into all aspects of drug therapy delivery.
