6.1 Safe Administration of Medicines & The 6 Rights
Key Takeaways
- The 6 Rights of Medication Administration (Right Patient, Right Drug, Right Dose, Right Route, Right Time, Right Documentation) form the foundational standard for NMC-registered nurses under the NMC Standards for Medicines Management.
- Patient identity must be verified using three distinct identifiers: full name, date of birth, and unique NHS number (or hospital ID number), cross-checked against the prescription chart and identity wristband.
- High-risk medicines—including insulin, anticoagulants (heparin, warfarin, DOACs), injectable opioids, and concentrated IV potassium—require dual independent verification and explicit rate calculations prior to administration.
- In the event of a medication administration error or near miss, the nurse must immediately assess patient safety, notify the prescriber and nurse-in-charge, complete an incident report (Datix), and uphold the statutory Duty of Candour.
6.1 Safe Administration of Medicines & The 6 Rights
Medicines management is one of the most critical clinical responsibilities of a registered nurse in the United Kingdom. According to the Nursing and Midwifery Council (NMC) Standards for Medicines Management, registered nurses are personally accountable for their practice in managing, preparing, and administering medicinal products. Safe administration requires meticulous clinical judgement, thorough knowledge of pharmacology, precise calculation skills, and strict compliance with legal frameworks and local trust policies.
The 6 Rights of Medication Administration
The 6 Rights of Medication Administration represent the core clinical checklist that every nurse must systematically execute prior to administering any therapeutic substance. Adherence to these six fundamental rights significantly reduces the incidence of preventable adverse drug events (ADEs).
| The Right | Clinical Standard & Nursing Action |
|---|---|
| 1. Right Patient | Confirm identity using three active identifiers (full name, date of birth, and NHS/hospital number) against the prescription chart and identity band. |
| 2. Right Drug | Verify the generic name of the drug against the prescription. Check packaging integrity, batch number, and expiration date. |
| 3. Right Dose | Confirm the dose prescribed matches safe therapeutic guidelines (BNF). Perform independent double-check calculations for complex doses. |
| 4. Right Route | Ensure the prescribed route is appropriate for the patient's condition and formulation. Never alter administration route without prescriber authorisation. |
| 5. Right Time | Administer at the specific scheduled time or within trust-approved windows (typically ±30 minutes). Verify timing relative to food or other drugs. |
| 6. Right Documentation | Record administration immediately after (never before) the drug is given on the paper MAR chart or Electronic Prescribing and Medicines Administration (ePMA) system. |
Electronic Prescribing & Covert Administration
Modern UK hospitals increasingly utilise ePMA systems to enhance prescribing safety and barcode scanning. However, nurses remain accountable for clinical verification regardless of digital prompts.
When a patient lacks decision-making capacity and refuses essential medication, covert administration (disguising medication in food or drink) may only be considered as a last resort. Under the Mental Capacity Act 2005, covert administration requires a formal multidisciplinary team (MDT) best-interest decision, involvement of the pharmacist to confirm stability, explicit documentation, and regular legal review.
Patient Identification & Allergy Verification
Patient identity verification must follow a rigorous, standardized protocol before any drug is removed from storage or administered.
The Three Identifiers
Nurses must cross-reference three unique patient identifiers:
- Full Legal Name (first name and surname)
- Date of Birth (DOB)
- Unique Health Identifier (NHS Number in England/Wales, CHI Number in Scotland, or Hospital Unit Number)
In inpatient settings, the nurse must verbally ask the patient to state their full name and date of birth whenever clinically feasible, while simultaneously checking the physical identity wristband against the Medication Administration Record (MAR). If the patient is confused, unconscious, or paediatric, identity must be confirmed via the wristband and validated by a second practitioner or parent/carer.
Allergy Status Verification
Allergy verification is a critical safety step. Before administering any medication, the nurse must:
- Inspect the prescription chart for recorded known drug allergies (KDA) or "No Known Drug Allergies" (NKDA).
- Check for a red allergy wristband on the patient.
- Verbally question the patient or carer regarding past adverse reactions, distinguishing between mild side effects (e.g., nausea) and true type-I hypersensitivity/anaphylaxis (e.g., urticaria, bronchospasm, angioedema).
- If an unrecorded allergy is identified, withhold the drug, inform the prescriber immediately, and update the alert record.
Routes of Administration & Specific Clinical Guidelines
Medicines are administered through diverse physiological routes, each possessing specific absorption characteristics and procedural rules.

Key Administration Routes
- Oral (PO): Assess swallowing ability. Modified-release (MR, XL) or enteric-coated (EC) tablets must never be crushed, as crushing alters bioavailability and causes rapid dose dumping.
- Subcutaneous (SC): Administered at a 45° to 90° angle into subcutaneous fat (e.g., abdomen, outer upper arm, anterior thigh). Rotate injection sites systematically to prevent lipohypertrophy (especially with insulin).
- Intramuscular (IM): Administered at a 90° angle into deep muscle mass. The ventrogluteal site (gluteus medius and minimus) is the primary recommended site for adult IM injections due to its thick muscle depth and absence of major blood vessels or nerves (unlike the dorsogluteal site). Utilize the Z-track technique to prevent fluid leakage into subcutaneous tissue.
- Intravenous (IV): Requires specific trust IV training. Must adhere strictly to infusion rates, compatibility charts, and flush protocols using 0.9% sodium chloride.
- Transdermal: Apply patches to clean, dry, hairless skin. Always remove the old patch before applying a new one, rotate sites, and avoid exposing patches (e.g., fentanyl) to direct heat sources (hot baths, heating pads), which accelerate drug absorption and risk fatal overdose.
- Epidural: Epidural lines must use neuraxial-specific connectors (NRFit) and yellow colour-coded tubing to completely physically prevent accidental connection of IV lines into the intrathecal space.
High-Risk Medicines & Controlled Drugs Management
Certain classes of medications carry a heightened risk of causing severe patient harm or mortality when administered incorrectly. These are designated as High-Risk (or High-Alert) Medicines.
High-Risk Medication Groups (PINCH)
- P - Potassium & Concentrated Electrolytes: Intravenous concentrated potassium chloride is a fatal cardiac arrest risk if infused rapidly; it must only be administered via pre-mixed diluted solutions on dedicated infusion pumps.
- I - Insulin: High risk of severe hypoglycemia. Always measure capillary blood glucose before administration. Draw up using dedicated insulin syringes (calibrated in Units, never mL).
- N - Narcotics / Opioids: Risk of respiratory depression. Require baseline respiratory rate checks and availability of naloxone.
- C - Chemotherapy / Cytotoxics: Requires specialized handling, personal protective equipment (PPE), and cytotoxic spill kits.
- H - Heparin & Anticoagulants: High risk of major hemorrhage. Require routine monitoring of coagulation profiles (aPTT, INR) and independent dual checking.
Controlled Drugs (CD) Regulations
Under the Misuse of Drugs Act 1971 and the Misuse of Drugs Regulations 2001, Schedule 2 Controlled Drugs (e.g., morphine, diamorphine, oxycodone, fentanyl) are subject to strict legal controls in UK healthcare facilities:
- Storage: Stored in a locked, solid metal Controlled Drugs cabinet securely fixed to a solid wall, accessed via a dedicated CD key held by the nurse-in-charge.
- Stock Verification: Stock balances must be counted and verified by two registered nurses (or authorized practitioners) during shift handovers and prior to every administration.
- CD Register: Every transaction (receipt, administration, or disposal) must be recorded immediately in a bound, page-numbered Controlled Drugs Register. The entry details date, time, patient name, dose given, amount discarded, balance remaining, and signatures of both checking nurses.
- Wastage: Any leftover or unadministered portion of a CD must be destroyed in the presence of a second nurse using a CD denaturing kit and recorded in the register.
Medication Errors, Near Misses & Duty of Candour
Despite stringent protocols, medication errors and near misses can occur. A near miss is an event that had the potential to cause harm but was intercepted prior to administration. A medication error is any preventable event that leads to inappropriate medication use or patient harm.
Step-by-Step Response to a Medication Error
- Immediate Patient Assessment: Assess the patient's clinical status, monitor vital signs, and initiate emergency life support or antidote administration if required.
- Prescriber Notification: Inform the prescribing doctor and nurse-in-charge immediately to receive corrective treatment orders.
- Incident Reporting: Complete an internal electronic incident report (e.g., Datix) before the end of the shift. Incident reports are non-punitive tools used for systemic Root Cause Analysis (RCA) and quality improvement.
- Statutory Duty of Candour: Under Regulation 20 of the Health and Social Care Act 2008, healthcare professionals have a legal and ethical obligation to be open and honest with patients/carers when an incident results in harm. The nurse must ensure the patient is informed promptly, given a clear factual explanation, provided a formal written apology, and supported appropriately.
