Medication Administration
The rights, the three checks, high-alert drugs, and what to do when you get it wrong.
The rights
Older texts list five. Most Canadian programs now teach ten, and the exam tests the additions as often as the originals.
| Right | The question you ask |
|---|---|
| Patient | Two identifiers — never the room number |
| Medication | Does the label match the order? |
| Dose | Is this a reasonable dose for this person? |
| Route | Is this form giveable by that route? |
| Time | Within the acceptable window? |
| Documentation | Charted after giving, never before |
| Reason | Why is this person on this drug? |
| Response | Did it do what it was meant to? |
| To refuse | The patient may decline |
| Education | Do they know what they're taking? |
Right to refuse trips people up. A competent adult may refuse any medication. You educate, you document, you notify the prescriber. You do not persuade, hide it in food, or give it anyway.
The three checks
Check the label against the order:
- When you take it from the drawer or cart
- When you prepare or pour it
- Before you give it, at the bedside
Three checks against one source is not three checks. The order is the source of truth each time.
Two identifiers
Name and date of birth, or name and medical record number. Never the room number and never the bed number — patients move, and that is precisely when errors happen.
Ask the patient to state their name rather than asking "Are you Mrs. Kaur?" Unwell people say yes to almost anything.
High-alert medications
These cause disproportionate harm when they go wrong, and most require an independent double-check:
- Insulin
- Anticoagulants (heparin, warfarin)
- Opioids
- Concentrated electrolytes, especially potassium chloride
- Chemotherapy
- Neuromuscular blocking agents
Never give concentrated potassium chloride as an IV push. It is fatal. It is always diluted and infused, and this is one of the most consistently tested single facts in nursing pharmacology.
Before you give it
Some drugs need an assessment first, and skipping it is the error:
| Drug | Check first | Hold if |
|---|---|---|
| Digoxin | Apical pulse, full minute | < 60 bpm in an adult |
| Beta blockers | Heart rate and blood pressure | Per parameters ordered |
| Antihypertensives | Blood pressure | Per parameters ordered |
| Insulin | Blood glucose | Hypoglycaemic |
| Opioids | Respiratory rate, sedation | RR < 12 or heavily sedated |
| Warfarin | INR | Above range |
When an error happens
- Assess the patient first. Always. Not the chart, not the phone.
- Notify the prescriber
- Complete an incident report
- Document the facts in the chart — what happened, what you assessed, who you notified
The incident report is a quality document, not part of the medical record. Do not chart "incident report filed" in the patient's notes.
Reporting an error is not optional and it is not a character failing. Systems improve from reported errors and cannot improve from hidden ones.
