Patient care technician screening questions: certifications, phlebotomy, EKG and unit fit
On this page
Patient care technician screening questions should find out which certifications the candidate holds and whether they are current (PCT certification, CNA, BLS, phlebotomy, EKG), which of the unit's tasks they have actually done on their own (vital signs, blood draws, 12-lead EKGs, glucose checks, mobility and personal care), on what kind of unit and with how many patients, and whether they know where their scope ends. In most hospitals the PCT is the person who notices first that a patient looks different. Screen for that judgment as hard as for the skills list.
This bank is for hospitals, dialysis clinics and agencies placing PCTs, sometimes called patient care assistants or nursing assistants. For nursing facility aides on a state registry, use the CNA screening questions; for dedicated lab or outpatient draw roles, use the phlebotomist screening questions. Clinic roles with front-office duties are closer to the medical assistant questions.
What "PCT" means depends on the employer
There is no single federal PCT license. The employer sets the requirements, and state law steps in for specific tasks. Ask the client for their list before the first call. The credentials you will most often see, as stated by the issuing bodies and regulations as of October 2026:
| Credential or rule | What it requires | Source |
|---|---|---|
| NHA Certified Patient Care Technician/Assistant (CPCT/A) | High school diploma or equivalent, plus a PCT training program within the last 5 years, or 1 year of supervised PCT work within the last 3 years (or 2 within 5). Renewed every 2 years with 10 continuing education credits. | NHA |
| Basic Life Support (BLS) | The AHA BLS Provider course completion card is valid for two years. | American Heart Association |
| Dialysis patient care technicians | High school diploma or equivalent, a training program approved by the medical director and governing body under an RN's direction, and certification under a state or national program within 18 months of hire. National programs include NNCC's CCHT and BONENT's CHT. | 42 CFR 494.140(e) |
| Phlebotomy in California | Unlicensed people performing venipuncture for a clinical laboratory need state phlebotomy certification: Limited Phlebotomy Technician (skin puncture only), CPT I (skin puncture and venipuncture) or CPT II (adds arterial puncture). | CDPH Laboratory Field Services |
| Phlebotomy in Washington | No one may practice as a medical assistant-phlebotomist unless certified. | RCW 18.360.020 |
Whether a PCT may do a task, such as removing a urinary catheter or discontinuing an IV, depends on state nursing rules and the hospital's policy. Do not promise a candidate a task list the unit has not confirmed.
Knockout questions
| Question | What a strong answer sounds like | Red flag |
|---|---|---|
| 1. Which certifications do you hold, who issued them, and when do they expire? | A list with issuers and dates: "NHA CPCT/A to next June, AHA BLS to March, state CNA active." | "Certified" with no issuer, or a BLS card from an online-only course the hospital does not accept. |
| 2. (California and other regulated states) Do you hold the state phlebotomy certificate this role needs? | Names the level, such as CPT I, and the expiry. | Has done blood draws in a regulated state without the certificate. |
| 3. (Dialysis) Are you certified as a hemodialysis technician, or when were you hired into your first dialysis job? | Holds a CCHT or CHT, or is inside the 18-month window with an exam date. | Past 18 months in dialysis and still not certified. |
| 4. The unit works [12-hour nights, every third weekend, holidays on rotation]. Can you work that schedule? | Yes, with the shifts they work now. | Days only, for a nights posting. |
| 5. The job involves repositioning and transferring patients and standing for long shifts. Can you do that, with or without accommodation? | Yes, and names the lift equipment they use. | None from the answer. Do not ask about injuries or health. |
Unit and skills questions
| Question | What a strong answer sounds like | Red flag |
|---|---|---|
| 6. What unit were you on, how many patients did you have, and what did a normal shift include? | "Telemetry, 32 beds, 8 to 10 patients on days: vitals every four hours, glucose checks, draws, baths, ambulation." | "A hospital" with no unit or patient numbers. |
| 7. How many blood draws did you do in a typical shift, and how do you identify the patient and label the tubes? | A number, two patient identifiers, labels at the bedside in the patient's presence, the order of draw. | Labels tubes at the nurses' station afterwards. |
| 8. Walk me through a 12-lead EKG. | Patient ID, explains, preps skin, places the six chest leads by landmarks and the four limb leads, keeps the patient still, checks the tracing, gives it to the nurse right away. | Cannot describe lead placement. |
| 9. A blood pressure comes back at 82/50 on a patient who was 130/80 this morning. What do you do? | Rechecks manually, looks at the patient, tells the RN at once, documents. | Charts it and moves on. |
| 10. A diabetic patient's fingerstick is 54. What do you do? | Tells the RN immediately, follows the hypoglycemia protocol only as directed, stays with the patient. | Gives juice and does not tell anyone, or waits until rounds. |
| 11. How do you get a high fall-risk patient to the bathroom safely? | Checks the plan of care, bed low, non-skid socks, gait belt or lift as ordered, stays within reach. | Leaves them alone "for privacy" against the plan. |
| 12. A patient is on contact precautions for C. diff. What do you do differently? | Gown and gloves, dedicated equipment, soap and water handwashing rather than gel alone, bleach-based cleaning per policy. | Uses hand gel only. |
Judgment and scope questions
| Question | What a strong answer sounds like | Red flag |
|---|---|---|
| 13. A nurse asks you to do something you have not been trained or checked off on. What do you do? | Says so politely, offers to help in another way, asks to be trained. | Does it "to help out." |
| 14. A patient refuses a bath and their morning vitals. What do you do? | Respects the refusal, tries again later, reports to the RN, documents. | Insists, or charts it as done. |
| 15. (Dialysis) Your patient's blood pressure drops and they say they feel dizzy mid-treatment. What do you do? | Alerts the nurse, follows the unit's hypotension protocol, monitors closely. | Keeps the treatment running unchanged. |
| 16. You get a needlestick. What happens next? | Washes the site, reports immediately, goes to employee health for evaluation. | Would not report it to avoid paperwork. |
A 12-minute phone-screen flow
- Minutes 0 to 2: unit, shifts, patient ratio, the task list and pay differentials.
- Minutes 2 to 5: knockouts 1 to 5, with only the state and setting items that apply.
- Minutes 5 to 9: question 6, then 7 or 8 depending on the unit's task list.
- Minutes 9 to 11: question 9 and question 13.
- Minutes 11 to 12: next step: interview with the unit manager and copies of certification cards.
The nurse phone screen questions are a good template for the manager interview if the PCT is on a path into nursing school, which many are.

Legal cautions
This section summarizes rules as of October 2026 and is not legal advice.
- Health and vaccination questions. OSHA's bloodborne pathogens standard requires employers to make the hepatitis B vaccine available at no cost within 10 working days of initial assignment, and an employee who declines signs a declination. Vaccination and immunity records belong in employee health after an offer, not in the phone screen. Ask whether the candidate can do the job's tasks, with or without accommodation.
- Pregnancy and lifting. Do not ask whether a candidate is pregnant or plans to be. Describe the lifting and ask the standard accommodation question; see the Pregnant Workers Fairness Act in hiring.
- Everything else. Age, national origin, religion and family questions are off limits; see illegal interview questions.
Questions people ask
Is a patient care technician the same as a CNA?
They overlap but are not the same. A CNA is listed on a state nurse aide registry under federal and state nursing facility rules, while patient care technician is usually a hospital or dialysis job title whose requirements are set by the employer and any state rules for specific tasks such as phlebotomy. Many hospitals accept either a CNA or a PCT certification.
What are the requirements for the NHA patient care technician certification?
According to the National Healthcareer Association, candidates for the Certified Patient Care Technician/Assistant need a high school diploma or equivalent, plus either a PCT training program completed within the last five years or supervised PCT work experience (one year within the last three years, or two years within the last five). Certification is renewed every two years with 10 continuing education credits.
Do dialysis patient care technicians need to be certified?
Yes, for Medicare-certified dialysis facilities. Under 42 CFR 494.140(e), patient care dialysis technicians need a high school diploma or equivalent, must complete a training program approved by the medical director and governing body, and must be certified under a state or national certification program within 18 months of being hired.
Can a patient care technician draw blood in California?
California requires unlicensed people who perform venipuncture for a clinical laboratory to hold a current phlebotomy certification, such as Certified Phlebotomy Technician I, issued through the Department of Public Health's Laboratory Field Services. Check the facility's policy and the state's rules before assigning blood draws to a PCT.
