The Rights of Medication Administration: How Nurses Prevent Drug Errors

Medication errors are a leading cause of avoidable harm in health care. The World Health Organization launched its Global Patient Safety Challenge, Medication Without Harm, to reduce severe, avoidable medication-related harm worldwide. Most nurses give dozens of doses every shift. The “rights” of medication administration are the checks that stop a slip from becoming a tragedy.

The rights, explained

Nursing schools teach five, six, seven or ten rights. The core five, plus the most widely added ones, are:

1. Right patient. Use at least two identifiers (such as full name and date of birth, or hospital number), checked against the wristband and the prescription. Never use the bed number or room. Ask the patient to say their name; don’t ask “Are you Mrs Ade?”
2. Right drug. Check the label three times: when taking it from storage, when preparing it, and at the bedside. Watch for look-alike, sound-alike names (e.g. hydralazine and hydroxyzine; metformin and metronidazole).
3. Right dose. Check the calculation; question any dose that seems unusual, especially for children. Have a colleague double-check high-alert drugs. See our drug calculation guide.
4. Right route. Oral, IV, IM, subcutaneous, nasogastric, inhaled. Some drugs are fatal by the wrong route; for example, vincristine must never be given intrathecally, and oral liquids should be drawn up in oral (not IV) syringes.
5. Right time. Give within the window set by policy. Timing matters especially for antibiotics, insulin, anti-Parkinson medicines, anticoagulants and pain relief.
6. Right documentation. Record immediately after giving, never before. If a dose is withheld or refused, document why and inform the prescriber.
7. Right reason. Know why the patient is getting it. If a patient on digoxin has a heart rate of 48, or a patient on an antihypertensive has a BP of 85/50, stop and check.
8. Right response. Monitor the effect: did the pain score fall, the blood glucose improve, the rash appear?
9. Right to refuse. A patient with capacity may refuse. Explain the consequences, document, and inform the prescriber.
10. Right education. Tell the patient what the medicine is for and what side effects to report.

Check allergies every time

Before giving any new drug, check the allergy status on the chart and wristband, and ask the patient. Know the cross-sensitivities, for example penicillins and other beta-lactams. If in doubt, don’t give it; ask. See our anaphylaxis guide.

High-alert medicines

Some drugs cause disproportionate harm when errors happen. The Institute for Safe Medication Practices (ISMP) and WHO highlight groups including:

• Insulin: never abbreviate “units” as “U” or “IU” (a “U” can be misread as 0, giving a tenfold dose). Use insulin syringes or pens only.
• Anticoagulants: heparin, warfarin, newer oral anticoagulants.
• Opioids: especially IV, and confusion between morphine and hydromorphone.
• Concentrated potassium chloride: never IV push; use pre-mixed bags.
• Chemotherapy.
• Sedatives and neuromuscular blocking agents.
• Methotrexate for non-cancer use, usually given once weekly; daily dosing in error has caused deaths.
• Magnesium sulfate and oxytocin in maternity care.

Why errors happen

Most medication errors are not caused by careless nurses but by systems that make errors easy: interruptions, short staffing, unclear handwriting, similar packaging, missing information and fatigue. Some practical defences:

• Protect the drug round: many hospitals use “do not disturb” tabards or signs during medicine rounds.
• Prepare medicines for one patient at a time, and give them straight away.
• Never give a drug someone else drew up, and label every syringe you prepare.
• Speak up if a prescription is unclear, illegible or seems wrong. Questioning a prescription is a professional duty, not a challenge to the prescriber.
• Use technology where available (barcode scanning, smart pumps), but don’t let it replace thinking.
• Medication reconciliation at admission, transfer and discharge to catch missed or duplicated drugs.

If you make an error

1. Check the patient first. Assess and take observations.
2. Tell the nurse in charge and the prescriber immediately. Follow their instructions (e.g. extra monitoring, an antidote).
3. Tell the patient honestly. Many regulators, including the NMC in the UK, set out a professional duty of candour.
4. Document the facts in the notes.
5. Report through your incident reporting system.

Hiding an error is far more serious than making one, and patients can be harmed while it is hidden. Good organisations use incident reports to fix systems, not to punish individuals. Errors also affect nurses: if you are struggling afterwards, seek support.
