The Rights of Medication Administration

These rights are the cornerstone of safe medication practices, acting as a checklist to prevent errors:

Right Patient: Verifying the patient's identity is paramount. Use multiple identifiers, such as name, date of birth, and medical record number, to ensure the medication is administered to the correct individual.
Right Medication: Carefully compare the medication order with the medication label. Be aware of look-alike, sound-alike drugs and double-check the generic and brand names.
Right Dose: Ensure the prescribed dose is within the safe dosage range for the patient. If unsure, consult with a pharmacist or physician before administering.
Right Route: Administer the medication via the route specified in the medication order (e.g., oral, intravenous, subcutaneous). Different routes affect absorption rates and bioavailability.
Right Time: Adhere to the prescribed administration schedule. Medications are often timed to maintain therapeutic blood levels or to coincide with meals or other treatments.
Right Documentation: Accurately record the administration of medication, including the date, time, dose, route, and any relevant patient observations.
Right Reason: Understand the reason the patient is receiving the medication. This knowledge helps in monitoring for therapeutic effects and potential adverse reactions.
Right Response: Monitor the patient for the intended effect of the medication and document the response. This helps determine if the medication is working as expected and if any adjustments are needed.
Right to Refuse: Patients have the right to refuse medication. If a patient refuses, explore the reasons for refusal, provide education, and document the refusal in the patient's record.
Right Education: Provide the patient with adequate information about the medication, including its purpose, how to take it, potential side effects, and any precautions.

Routes of Administration

Medications can be administered through various routes, each with its own advantages and disadvantages:

Oral (PO): Medications are swallowed and absorbed through the gastrointestinal tract. This is a convenient and common route, but absorption can be affected by food, other medications, and gastrointestinal motility.
Sublingual (SL): Medications are placed under the tongue and absorbed directly into the bloodstream. This route bypasses the first-pass metabolism in the liver, resulting in faster absorption.
Buccal: Medications are placed between the cheek and gum, similar to sublingual administration.
Intravenous (IV): Medications are injected directly into a vein, providing immediate absorption and precise control over dosage.
Intramuscular (IM): Medications are injected into a muscle. Absorption is generally faster than subcutaneous administration but slower than intravenous.
Subcutaneous (Subcut): Medications are injected into the subcutaneous tissue, the layer of fat beneath the skin. Absorption is slower than intramuscular administration.
Topical: Medications are applied to the skin or mucous membranes. Absorption is typically localized, but systemic absorption can occur.
Inhalation: Medications are inhaled into the lungs, allowing for rapid absorption into the bloodstream.
Rectal (PR): Medications are inserted into the rectum. This route is useful when oral administration is not possible.
Transdermal: Medications are applied to the skin via a patch, allowing for sustained release of the medication over a prolonged period.

Accurate Documentation

Meticulous documentation is essential for maintaining patient safety and ensuring continuity of care. Documentation should include:

The medication name, dose, route, and time of administration.
The patient's response to the medication, including any adverse effects.
Any relevant patient observations or assessments.
Any instances where medication was withheld or refused, along with the reason.
