The 5 Rights of Medication Administration

Medication administration is the most frequent high-risk task nurses perform. A single error—a misplaced decimal, a similar-sounding name, or a distracted check—can result in severe patient harm or death. The 5 Rights of Medication Administration function as the universal safety protocol for nurses, pharmacists, and prescribers. Adherence to these rights is not merely a recommendation; it is the legal standard of care. This guide details the critical checkpoints and cognitive frameworks required to ensure medication safety in high-pressure clinical environments.

The Medication Safety Framework

The “Rights” serve as the final barrier between a potential error and the patient. According to the Institute for Safe Medication Practices (ISMP), robust safety cultures integrate these rights with system safeguards like barcode scanning and independent double-checks.

1. Right Patient

Objective: Ensure the recipient matches the prescriber’s order.

Verification Protocol

• Two Identifiers: Mandatory use of Full Name and Date of Birth (DOB). Compare the patient’s verbal statement to the wristband and the Medication Administration Record (MAR).
• Barcode Scanning: Scan the wristband immediately prior to administration. This electronic match reduces identification errors by up to 41%.
• Special Populations: For non-verbal, comatose, or confused patients, verify identifiers with a second nurse or family member, and confirm the Medical Record Number (MRN) matches the band.

Alert: Never use room numbers as identifiers. Patients transfer rooms frequently.

2. Right Drug (Medication)

Objective: Confirm the medication selected matches the order.

The Three Checks

Nurses must verify the label against the MAR at three distinct points:

1. Retrieval: When pulling the medication from the Automated Dispensing Cabinet (ADC).
2. Preparation: When preparing the dose (cutting, crushing, drawing up).
3. Bedside: Immediately before administration to the patient.

Look-Alike Sound-Alike (LASA) Drugs

Drugs with similar names (e.g., Humalog vs. Humulin, Hydralazine vs. Hydroxyzine) pose high risks. Use Tall Man Lettering (e.g., hydrOXYzine) to distinguish them. Always verify the indication; if a patient has hypertension, Hydroxyzine (for anxiety/itching) is likely incorrect.

3. Right Dose

Objective: Verify the dosage is safe and matches the order.

Calculation & Verification

• Unit Conversion: Convert units accurately (e.g., grams to milligrams). Errors here often result in 10-fold overdoses.
• Weight-Based Dosing: Critical in pediatrics. Verify the patient’s current weight in kilograms. Calculate safe range (mg/kg/day).
• High-Alert Medications: Drugs like Insulin, Heparin, and Chemotherapy require an Independent Double-Check. A second nurse must independently calculate and verify the dose before administration.

The “Leading Zero” Rule

Never use a trailing zero (5.0 mg); always use a leading zero (0.5 mg). Misreading “5.0” as “50” is a common, fatal error.

4. Right Route

Objective: Administer via the prescribed and safe path.

Critical Considerations

• IV vs. IM vs. Oral: Ensure the formulation matches the route. Injecting an oral suspension IV can cause embolisms.
• Enteral Tubes: Verify tube placement (pH aspirate, X-ray) before administering meds. Do not crush Extended-Release (ER), Sustained-Release (SR), or Enteric-Coated (EC) tablets; this alters absorption rates and can cause toxicity.
• Injections: Select appropriate needle gauge and length based on tissue depth and viscosity.

5. Right Time

Objective: Maintain therapeutic blood levels.

Administration Windows

• Time-Critical Medications: Administer within 30 minutes of scheduled time (e.g., Insulin, Antibiotics). Delays compromise efficacy.
• Non-Time Critical: Typically administered within 1-2 hours of scheduled time (e.g., Daily vitamins).
• PRN (As Needed): Verify the time of the last dose to ensure the prescribed interval has passed.

The “Plus 5” Rights

Modern safety standards extend beyond the original five.

• Right Documentation: Document immediately after (never before) administration. Include site of injection and patient response.
• Right Reason (Indication): Verify the patient has the condition the drug treats. (e.g., Don’t give antihypertensives if BP is low).
• Right Response (Evaluation): Did the drug work? (e.g., Pain score decreased). Did it cause harm? (e.g., Respiratory depression).
• Right to Refuse: Patients may decline medication. Nurse must educate on risks, document refusal, and notify the provider.
• Right Education: Patient understands what they are taking and why.
