✍️ Sample CRNFA Questions & Answers

1. Preoperative marking of the surgical site is performed to prevent which type of adverse surgical event?
Wrong-site, wrong-side, or wrong-procedure surgery

Surgical site marking is a Joint Commission Universal Protocol requirement specifically designed to prevent wrong-site, wrong-side, and wrong-procedure surgeries.

2. Which electrosurgical mode uses a continuous waveform to achieve tissue cutting with minimal hemostasis?
Cut mode

The cut mode delivers a continuous, unmodulated waveform that rapidly vaporizes tissue, producing a clean cut with minimal lateral thermal spread.

3. Which type of needle holder is most appropriate when suturing delicate cardiovascular tissue?
Castroviejo needle holder

The Castroviejo needle holder is a fine, spring-loaded instrument designed for delicate cardiovascular and ophthalmic suturing.

4. Which suture material is most appropriate for a contaminated abdominal wound requiring fascial closure?
Polydioxanone (PDS) — monofilament slowly absorbable

Monofilament slowly absorbable sutures like PDS are preferred in contaminated wounds because they provide prolonged tensile strength and their monofilament structure harbors fewer bacteria than braided sutures.

5. During a laparoscopic procedure, the surgeon asks the CRNFA to adjust the monopolar ESU settings. Which finding on the ESU display indicates that the dispersive pad alarm is activated?
The contact quality monitor indicator shows poor pad contact

Modern ESUs with contact quality monitoring display a poor contact warning when the dispersive pad has inadequate skin contact, preventing unsafe current return.

6. A fire has started on the sterile drape from an ESU spark near supplemental oxygen. The CRNFA's immediate priority is to:
Remove the burning drape from the patient, stop oxygen flow, and extinguish the fire away from the patient

The RACE/PASS OR fire response prioritizes removing the burning material from the patient and cutting off the oxygen supply (the oxidizer) before using an extinguisher away from the patient's airway.
