cath lab radiology technician Interview Questions and Answers

1. What is your experience with various types of catheters and guidewires?

   • Answer: I have extensive experience with a wide range of catheters, including diagnostic catheters (e.g., Judkins, pigtail, multipurpose), interventional catheters (e.g., balloon angioplasty catheters, stents, drug-eluting stents), and guidewires (e.g., hydrophilic, support, stiff). I am familiar with their respective uses, limitations, and proper handling techniques, including selection based on patient anatomy and procedure type. I understand the importance of maintaining sterility and preventing complications.

2. Describe your knowledge of cardiac anatomy and physiology.

   • Answer: My understanding of cardiac anatomy includes the chambers of the heart, valves, coronary arteries, and major veins. I'm familiar with the conduction system and its role in maintaining heart rhythm. My knowledge of physiology encompasses the mechanics of blood flow, cardiac output, and the regulation of heart rate and blood pressure. This understanding is crucial for accurate catheter placement and interpretation of fluoroscopic images.

3. How proficient are you with fluoroscopy equipment and image acquisition?

   • Answer: I am highly proficient in operating fluoroscopy equipment, including adjusting parameters such as kVp, mA, and pulse rate to optimize image quality while minimizing radiation exposure to both the patient and myself. I understand the principles of image intensification and digital subtraction angiography (DSA). I can efficiently acquire and process images, ensuring proper labeling and documentation.

4. Explain your understanding of radiation safety protocols.

   • Answer: I am well-versed in ALARA principles (As Low As Reasonably Achievable) and adhere strictly to radiation safety protocols. This includes proper use of lead shielding, time optimization, distance maximization, and maintaining accurate radiation exposure records. I am familiar with the regulations and guidelines set by regulatory bodies like the FDA and our institution's radiation safety department.

5. How do you handle emergency situations in the cath lab?

   • Answer: In emergency situations, I prioritize patient safety and remain calm and focused. I follow established emergency protocols, which include immediately notifying the physician, assisting with resuscitation efforts, and maintaining accurate documentation of the event. I am trained in basic life support (BLS) and advanced cardiac life support (ACLS), and I know how to respond effectively to various emergencies like cardiac arrest or bleeding.

6. Describe your experience with hemodynamic monitoring.

   • Answer: I am experienced in monitoring hemodynamic parameters such as blood pressure, heart rate, cardiac output, and oxygen saturation. I understand the significance of these measurements and can identify and respond to abnormal readings. I am proficient in using various hemodynamic monitoring equipment and interpreting the data to assist the physician in making informed decisions.

7. How do you maintain a sterile field during procedures?

   • Answer: Maintaining a sterile field is paramount. I strictly adhere to established sterile techniques, including proper hand hygiene, gowning and gloving procedures, and meticulous preparation of the equipment and supplies. I'm vigilant in identifying and addressing any potential breaches in sterility to prevent infection. I understand the importance of maintaining the integrity of sterile packages and drapes.

8. What is your experience with post-procedure patient care?

   • Answer: My responsibilities include monitoring the patient's vital signs, assessing for complications (bleeding, hematoma formation, allergic reactions), and providing post-procedure education. I assist in transferring the patient to the recovery area and ensure smooth communication with the nursing staff.

9. How familiar are you with different types of cardiac procedures performed in the cath lab?

   • Answer: I'm familiar with a wide range of procedures, including diagnostic coronary angiography, coronary intervention (PCI, angioplasty, stent placement), peripheral interventions, pacemaker and ICD implantations, and electrophysiology studies. I understand the steps involved in each procedure and can anticipate the necessary equipment and supplies.
