angio technologist Interview Questions and Answers

1. What is your understanding of angiography?

   • Answer: Angiography is a medical imaging technique used to visualize the inside of blood vessels and organs of the body, with a particular focus on the arteries and veins. It involves injecting a contrast medium into the bloodstream and then using X-ray imaging to create images of the blood vessels, allowing doctors to diagnose a variety of conditions, such as blockages, aneurysms, and tumors.

2. Describe your experience with different types of angiography.

   • Answer: (This answer will vary depending on the candidate's experience. A good answer would mention several types, such as coronary angiography, cerebral angiography, peripheral angiography, and potentially others like CT angiography or MRI angiography, explaining their differences and applications.) For example: "I have extensive experience in coronary angiography, performing numerous procedures to visualize coronary arteries for the diagnosis of coronary artery disease. I am also proficient in peripheral angiography, assisting in the diagnosis and treatment of peripheral arterial disease. I have some experience with cerebral angiography, though it is less frequent in my current role."

3. Explain the role of contrast media in angiography.

   • Answer: Contrast media are iodine-based solutions injected into the bloodstream. They temporarily increase the radiopacity of the blood vessels, making them clearly visible on X-ray images. This allows for precise visualization of the vessels' structure and patency.

4. What are the potential complications of angiography?

   • Answer: Potential complications include bleeding at the puncture site, hematoma formation, allergic reactions to the contrast media (ranging from mild rash to anaphylaxis), infection, kidney damage (especially in patients with pre-existing renal insufficiency), stroke (in cerebral angiography), and arterial dissection or spasm. It's crucial to carefully assess patients beforehand and monitor them closely throughout and after the procedure.

5. How do you prepare a patient for an angiography procedure?

   • Answer: Patient preparation includes reviewing their medical history, assessing for allergies (especially to iodine), checking renal function, obtaining informed consent, explaining the procedure and potential risks, instructing them on fasting requirements (if necessary), and ensuring they are comfortable and have any necessary medications administered.

6. Describe your experience with different types of catheters used in angiography.

   • Answer: (This will vary based on experience, but should include a description of various catheter types, sizes, and uses – e.g., Judkins catheters, pigtail catheters, etc. and when each type is appropriate). For example: "I'm familiar with a range of catheters, including Judkins catheters for coronary angiography, which are designed to selectively catheterize coronary arteries, and pigtail catheters for aortography, which allow for complete visualization of the aorta."

7. How do you ensure the safety and sterility of the procedure?

   • Answer: Maintaining sterility is paramount. This involves strict adherence to sterile technique throughout the procedure, including proper hand hygiene, use of sterile gloves, gowns, drapes, and instruments. The procedure room must be properly cleaned and disinfected before each procedure. The equipment used must be sterile and checked before use. All materials in contact with the patient's body are sterile single-use items.

8. What are the key differences between digital subtraction angiography (DSA) and conventional angiography?

   • Answer: DSA uses computer processing to subtract the background images from the contrast-enhanced images, resulting in clearer visualization of the blood vessels. Conventional angiography relies on direct image acquisition and subtraction is done manually, creating lower quality images and more radiation exposure.

9. How do you handle emergencies during an angiography procedure?

   • Answer: Emergency preparedness is vital. I would remain calm and quickly assess the situation. This could involve anything from managing a puncture site bleed (pressure, haemostasis) to recognizing and responding to an allergic reaction (administering medication as directed by the physician), to managing a potential cardiac event (CPR). Immediately notifying the physician is crucial, alongside obtaining assistance from other members of the medical team.

10. What is your understanding of radiation safety and how do you minimize radiation exposure to both the patient and yourself?

    • Answer: Radiation safety is a major concern. I understand ALARA principles (As Low As Reasonably Achievable). This involves optimizing exposure settings on the imaging equipment, utilizing lead shielding for both the patient and myself, proper positioning techniques to minimize unnecessary exposure, and maintaining appropriate distance from the radiation source. Using pulse-spray techniques on the injector minimizes radiation exposure and improves image quality. I always follow safety protocols, including the use of personal radiation monitoring devices.

11. How do you maintain and troubleshoot angiography equipment?

    • Answer: (This will depend on experience and specific equipment. A good answer will mention routine checks, preventative maintenance, and familiarity with basic troubleshooting). For example: "I am familiar with routine quality control checks on the X-ray equipment, including daily calibration and image quality assessments. I can troubleshoot minor issues such as injector malfunctions or image distortion, but for major repairs, I would contact the biomedical engineering department."

12. Describe your experience with post-procedural patient care.

    • Answer: Post-procedural care involves monitoring vital signs, assessing the puncture site for bleeding or hematoma, ensuring patient comfort, administering any necessary medications (e.g., pain relievers), providing clear post-procedure instructions, and educating the patient about potential complications and follow-up care.

13. How do you maintain accurate records and documentation during and after an angiography procedure?

    • Answer: Accurate documentation is critical for patient safety and legal reasons. I meticulously document all aspects of the procedure, including patient demographics, medical history, contrast media used, catheterization details, any complications encountered, medications administered, post-procedure findings, and instructions given to the patient. This is typically done electronically using a picture archiving and communication system (PACS) and an electronic medical record (EMR).

14. How do you handle patient anxiety or fear before and during the procedure?

    • Answer: I approach each patient with empathy and understanding. Before the procedure, I explain the process clearly, answering any questions and addressing concerns. During the procedure, I maintain open communication, reassuring the patient and offering support. I may use distraction techniques or provide emotional support as needed. Collaboration with the physician and nursing staff ensures patient comfort and reduces anxiety.

15. What are some of the ethical considerations involved in angiography?

    • Answer: Ethical considerations include obtaining informed consent, maintaining patient confidentiality, ensuring patient safety and minimizing risks, respecting patient autonomy, and acting with integrity and honesty. Ethical dilemmas might arise if a patient is unable to provide informed consent, or if there is a conflict between patient wishes and medical necessity.

16. What are your strengths as an angio technologist?
