1. Definition of Medication Administration

Medication administration is the process of safely preparing, giving and monitoring a prescribed medication to a patient using the correct drug, dose, route and timing, while following appropriate patient-safety principles.

Medication administration is not simply the act of giving a tablet or injection. It includes assessment before administration, checking the medication order, identifying the patient, evaluating contraindications and allergies, administering the medication correctly, monitoring the response and documenting the care.

2. Objectives of Medication Administration

• Provide the prescribed therapeutic effect.
• Prevent medication-related complications.
• Maintain patient safety.
• Reduce medication errors.
• Achieve the desired pharmacological response.
• Monitor therapeutic and adverse effects.
• Educate patients about their medications.
• Promote adherence to the treatment plan.

3. Nurse's Responsibility in Medication Administration

Medication administration is a professional responsibility that requires knowledge of pharmacology, patient assessment, medication safety and clinical judgment.

• Understand the medication and its therapeutic purpose.
• Verify the medication order.
• Identify the patient correctly.
• Check allergies.
• Assess relevant vital signs and laboratory values.
• Check contraindications and precautions.
• Calculate the dose accurately when required.
• Use the correct route and technique.
• Monitor therapeutic response.
• Identify and report adverse reactions.
• Document medication administration accurately.
• Educate the patient.

Important:

A nurse should not administer a medication that is unclear, incomplete, unsafe or inconsistent with the patient's clinical situation without obtaining clarification through the appropriate clinical process.

4. Rights of Medication Administration

Medication-safety frameworks commonly teach the traditional medication rights. Modern practice often expands these rights to include additional safety checks.

Traditional Five Rights

Right	Meaning
Right Patient	Confirm that the medication is intended for the correct patient.
Right Medication	Verify the medication name and formulation.
Right Dose	Verify that the dose is correct.
Right Route	Administer by the prescribed and appropriate route.
Right Time	Administer according to the prescribed schedule and applicable timing requirements.

Additional Medication Rights

• Right documentation
• Right reason/indication
• Right response
• Right assessment
• Right education
• Right to refuse
• Right evaluation

Right Patient → Right Medication → Right Dose → Right Route → Right Time → Right Documentation → Right Response

NORCET Exam Tip:

Do not memorize only five rights. In clinical practice, medication safety requires multiple independent checks before, during and after administration.

5. Medication Safety Principles

• Use at least two appropriate patient identifiers according to institutional policy.
• Check allergies before administration.
• Review the medication order carefully.
• Compare the medication label with the medication record/order according to facility policy.
• Check expiration date.
• Inspect the medication for contamination, damage or unusual appearance.
• Never administer an unidentified medication.
• Never use a medication from an improperly labelled container.
• Perform required calculations carefully.
• Use appropriate measuring devices.
• Reduce interruptions during medication preparation.
• Use barcode medication administration when available and applicable.
• Monitor the patient after administration.
• Document promptly and accurately.

6. Medication Order / Prescription

Before administering medication, the nurse should ensure that the medication order is complete, legible/electronically clear and clinically appropriate within the nurse's scope and institutional policy.

Important Components

• Patient identification
• Medication name
• Dose
• Route
