Which of the following is a key piece of information needed for documenting medication administration?

Dosage is a key piece of information needed for documenting medication administration because it specifies the exact amount of the medication that was given to the patient. Accurate documentation of dosage is crucial for several reasons: it ensures that the patient receives the correct amount of medication, helps in monitoring the effectiveness of the treatment, and prevents potential overdose or underdose scenarios. Recording the dosage also facilitates communication among healthcare providers, ensuring continuity of care and reducing the risk of medication errors. Knowing the precise dosage is essential for tracking medication administration trends and assessing the patient's response to therapy over time.
