The Blood Draw You Are Not Trained For
You are a newly hired RN on a busy outpatient infusion unit, three weeks off orientation. The unit is short-staffed; two nurses called in sick. There are nine patients waiting, several with port-a-caths due for lab draws before their infusions can be released by pharmacy. The charge nurse hands you a vacutainer set and a Huber needle and says, 'You've watched me do this a dozen times - just get Mrs. R's labs from her port, we're drowning, and pharmacy won't release her chemo without a CBC.' You have never performed a port access independently; your competency checklist for central venous access is not signed off. Mrs. R is anxious and asks you, 'Have you done this before?'
1. What do you do, and how do you handle Mrs. R's direct question?

Decline the independent port access and answer Mrs. R honestly.
The task: Watching a procedure is not competency. Port access is a skill with real harm potential (infection, extravasation, air embolism, needle dislodgement), and your unit's checklist exists precisely because unsupervised practice is unsafe. Staffing pressure does not create competence. Say clearly to the charge nurse: 'I'm not signed off on port access; I can't do this independently. Who can?'
The patient's question: Answer truthfully and without alarming her: 'I'm going to have a nurse who is trained and checked off on this do your draw - I'll stay with you.' Never say 'yes, I've done this many times' when you have not. Deceiving a patient about your competence is both an ethical breach and a safety issue.
Solve the staffing problem, don't just refuse: offer to do what you are competent at (start peripheral lines where appropriate, verify orders, prepare supplies, chaperone, run the queue), and ask the charge nurse to escalate for a float or to sequence the port patients to the one credentialed nurse. Refusing one task while offering alternatives is collaboration, not obstruction.
2. The charge nurse responds, 'Everyone here learned by doing. If you won't, Mrs. R's chemo gets delayed and that's on you.' How do you respond, and what do you document?

Hold the line, reframe the accountability, and protect yourself with a record.
- Reframe: the delay is caused by a staffing gap and an uncredentialed assignment, not by your refusal to practice outside your competence. Say so calmly: 'I'm not willing to put a patient at risk to save time. I'll help find a credentialed nurse or escalate.'
- Escalate up the chain - nursing supervisor/house manager - and state the facts: number of port patients, one credentialed nurse, your competency status, and the potential delay. Ask for a float or a plan.
- Do not be worn down by repetition. Persistence from a superior is not new authority; the competency requirement does not change because the shift is busy.
- Documentation: an objective, non-blaming note or incident/assignment-against-objection record - time, who assigned the task, that you stated you were not competency-validated, that you requested a credentialed nurse, the escalation, and the outcome for Mrs. R. Avoid editorializing about the charge nurse's character; record facts.
- Follow up afterward with your manager/educator about getting signed off properly so this does not recur.
