The medication administration rights are a structured safety check around giving a medicine. MedMaths uses six core rights — right patient, medicine, dose, route, time and documentation — while also teaching broader safeguards such as indication, response, patient choice, barcode workflows and medicine-specific checks. The exact number of “rights” varies between organisations, so the local approved process remains authoritative.
The rule to remember
A maths answer is not an administration instruction.
A calculation can be correct while the order is questionable or the available dosage form cannot safely deliver the intended dose. Stop and resolve the problem rather than making the medicine fit the maths.
What are the six rights of medication administration?
Use the approved patient-identification process before administration.
Match the active order to the exact medicine and relevant product/formulation.
Confirm the authorised dose, units, maths, required limits and a safe way to deliver it.
Use the authorised route and a formulation that supports that route.
Check the active schedule, frequency, last dose and any relevant PRN/time-critical rules.
Document what actually happened after administration or non-administration.
Veterans Health Administration guidance uses this six-right model. Other nursing frameworks use five, seven, eight or more rights and may name additional concepts such as right reason/indication, right response, education, assessment or refusal. The numbered list is a memory framework, not a complete medication-safety system.
Right patient: identify the person using the approved process
In Joint Commission settings in the United States, use at least two approved patient identifiers. A room or bed number is a location, not an acceptable identifier. Australian processes commonly require at least three approved identifiers. Use the process required in your setting rather than assuming one universal identifier count.
Right medicine: match the exact current product context
Do not match by package colour or a familiar medicine name alone. Compare the active/latest authorised order with the product selected, including the relevant medicine name, formulation and strength. Allergy and adverse drug reaction information, expiry/label information and other medicine-specific checks remain part of the wider safety process.
Right dose: the number must also be safely deliverable
A useful right-dose check asks four linked questions:
- Is this the current authorised dose?
- Are the units and medication maths correct?
- Does the result meet any applicable authorised medicine-specific range, maximum or protocol check?
- Can the intended dose actually be delivered safely with the exact product/formulation available?
A “no” or “not sure” at any of these points is a stop-and-resolve signal. A correct calculation does not override a questionable order, changed clinical state, unsuitable dosage form or medicine-specific administration requirement.
Review the MedMaths calculation-checking method →Example: the maths says 1.5 capsules — what happens next?
Imagine a fictional order and the available stock strength correctly calculate to 1.5 capsules. Keep 1.5 capsules as the mathematical result. It is not permission to round to 1 or 2 capsules, open the capsule, divide its contents or otherwise improvise.
If the result looks wrong, unusual or incompatible with the dosage form, do not make the product fit the number.
Recheck the active order, units, calculation and exact current product/strength/formulation.
If the intended medicine, dose, route or frequency is unclear or questionable, use the authorised prescriber clarification process. Do not infer what was meant.
If the intended dose is confirmed but the available dosage form cannot safely deliver it, involve pharmacy or the authorised medicines-information process. A different strength, suitable liquid, dispersible formulation, pharmacy-prepared product or validated product-specific method may be appropriate depending on the medicine.
Any required change to the authorised medicine/order/product/route/instructions must be authorised and documented according to local policy.
If a new strength or concentration is supplied, discard the old calculation and start again using the exact product that will actually be used.
Prescriber clarification and pharmacy advice solve different problems
Clarifies or confirms the intended medicine, dose, route, frequency and clinical order when the order is unclear or questionable.
Supports medication-order review and helps determine how a confirmed intended dose can be supplied/prepared/administered using an appropriate product or formulation.
Local workflows and scopes vary. MedMaths does not dictate who must rewrite a chart or which alternative formulation should be used. The safe principle is to resolve the intended order and the formulation problem through the authorised clinical process before administration.
Do not assume tablets, capsules and liquids are interchangeable
Not every tablet can be split or crushed, and not every capsule can be opened. Modified-release, gastro-resistant and other specialised formulations can be particularly sensitive to manipulation. Even when a capsule may be opened, that does not automatically mean its contents can be divided to manufacture a partial dose.
An oral liquid can sometimes solve a dosage-form problem, but liquid is not an automatic substitute. Switching formulation can change bioavailability, release profile, dosing frequency, equivalent dose, excipient exposure or monitoring requirements. Use the exact authorised product and product-specific guidance.
Review tablet and capsule calculation boundaries →Right time: check more than the clock
Right time includes the active schedule/frequency and, when relevant, the previous administration, PRN indication/minimum interval and any medicine-specific or local time-critical process. Do not invent one universal “early/late” window for every medicine.
Right route: route and formulation belong together
Oral, enteral-tube, intravenous, subcutaneous and intramuscular routes are not interchangeable. A formulation that is suitable for one route may not be suitable for another. Do not convert routes or manipulate products by assumption.
Right documentation: record what actually happened
Do not pre-document a medicine as administered. After administration, document what actually occurred using the local workflow. If the medicine was refused, withheld, omitted or not given, record the appropriate non-administration outcome rather than creating a misleading record.
Reason and response: the six rights are not the whole system
Broader nursing frameworks commonly ask why the medicine is being given and what response should be assessed afterwards. The indication should make sense in the current clinical context, and required effects, observations or adverse reactions may need monitoring after administration. Patient education and informed refusal also remain important even when the six core rights match.
Barcode scanning and independent checks
Barcode medication administration can add a useful patient/product verification layer where it is available and required, but it does not replace reading the active order and label or using clinical judgement. Do not use proxy barcodes or other workarounds simply to make a mismatch alert disappear.
Some high-risk medicines or processes require an independent second check. Follow the exact local policy/protocol rather than assuming that every medicine needs “two nurses” or that a double check makes an otherwise questionable order safe.
Three different problems can produce the same uncomfortable result
Recalculate using the verified current values and compatible units.
Stop and use the authorised prescriber clarification process. Do not guess the intended dose.
Resolve the product/formulation through pharmacy or the authorised medicines-information process before proceeding with an authorised plan.
Remember
Right dose = right amount + appropriate product/formulation + a safe authorised way to give it.
If something does not make sense, do not make it fit. Stop, recheck and resolve the problem through the authorised clinical process.
