Drug Interactions: Other medications the patient is taking can influence dosage.
Common Dosage Forms
Medications come in various dosage forms, including:Each form has its unique considerations for dosage and administration.
Role of Nurses in Medication Dosage
Nurses play a pivotal role in the administration of medication dosages: Assessment: Evaluating the patient's condition before administering medication.

Conclusion
Understanding and accurately administering medication dosages is a fundamental aspect of nursing practice. Ensuring the right dosage requires a comprehensive understanding of the medication, patient-specific factors, and vigilant monitoring. By adhering to best practices and leveraging technology, nurses can play a crucial role in promoting patient safety and effective treatment outcomes.
