Common Patient Identification and Consent Mistakes
A misidentification error is treated as a critical, non-negotiable failure regardless of how well the rest of the draw was performed — this is the one mistake category with real patient-safety consequences.
How this procedure is evaluated
Your training program instructor or clinical preceptor observes your technique and decides whether a draw or procedure counts toward your required documentation (at least 30 venipunctures and 10 capillary punctures for NHA CPT eligibility). A technique error doesn't just risk the sample — it can mean the attempt doesn't count toward your total.
The 5 Most Common Mistakes
Asking "Are you Mr. Smith?" instead of "Can you tell me your full name?" — a yes/no question doesn't verify identity.
Relying on a room number or bed assignment alone to identify a patient.
Proceeding with a draw despite a mismatch between the wristband and requisition, assuming it's a clerical error.
Skipping consent because the order "says to draw it" — consent and the physician's order are two separate requirements.
Arguing with or pressuring a patient who refuses, rather than notifying the nurse or ordering provider.
Exactly What Your Instructor Is Checking
These are the specific checkpoints your instructor or preceptor documents for this procedure.
- ✓
Uses two independent identifiers (full name and date of birth), asked as open questions, not yes/no confirmations.
- ✓
Cross-checks identifiers against both the requisition and the patient's wristband when one is present.
- ✓
Stops and escalates rather than drawing when identifiers don't match.
- ✓
Clearly explains the procedure and obtains verbal consent before beginning.
- ✓
Responds appropriately — notifying the care team, not arguing — if the patient refuses.
How to Avoid These Mistakes
These tips come from the most common mistake patterns in Patient Identification and Consent.
- →
This is one of the few procedures where a single error (wrong-patient draw) can cause real harm — treat identification as non-negotiable, every time, with no exceptions for "I already know this patient."
- →
If anything about the identifiers feels inconsistent, it costs almost nothing to double-check and a great deal to get wrong.
