We also know that everyone likes to study differently, so we offer three different ways to use your DHA Cardiac Interventional Radiography practice exams:

  • Timed DHA Cardiac Interventional Radiography Practice Test Mode: Timed tests are just like the DHA Cardiac Interventional Radiography exam. Our system sets the test time to the same time limit, or time limit per question, that you will experience with the actual exam on test day. This is a great method of practicing your pacing, especially if you're concerned about completing your exam within the time limit.

  • Untimed DHA Cardiac Interventional Radiography Practice Test Mode: With this option, you can take your time and thoroughly consider each question before answering. This rush-free mode is recommended for those dipping their toes into exam prep or just starting on their journey to take the DHA Cardiac Interventional Radiography. It is a great way to test your knowledge with no time limit and highlight blind spots you will need to come back to in your studies - one of the many advantages of taking DHA Cardiac Interventional Radiography practice exams with Exam Edge!

  • DHA Cardiac Interventional Radiography Study Guide Mode: Not sure where to even begin with your studying? Try a practice test in explanation mode. The questions act as a study guide, giving you the option to see the answers as you take the test. Study guide mode is an effective way to review the DHA Cardiac Interventional Radiography exam subject matter before you take the exam in a timed format.

DHA Cardiac Interventional Radiography - Features Sample Questions

Pacemakers can be affected by a type of interference called EMI.  Which of the following can be a source of EMI?

Correct Answer:
industrial generators.
**pacemakers and electromagnetic interference (emi)**

pacemakers, critical devices implanted to regulate heartbeats, can be vulnerable to a phenomenon known as electromagnetic interference (emi). emi refers to the disruption that occurs in an electronic device when it is exposed to an electromagnetic field. this interference can potentially cause the pacemaker to malfunction, leading to incorrect heart pacing which can be detrimental to the user.

sources of emi are varied and can be found in everyday environments. here's a look at some common sources: * **industrial generators:** these devices, often used in factories or large industrial settings, generate substantial electromagnetic fields that can disrupt the functioning of a pacemaker. the size and power of these generators make them a significant source of emi, and it is advisable for pacemaker users to maintain a safe distance. * **mri machines:** magnetic resonance imaging (mri) machines are well-known for their strong electromagnetic fields. due to this, they pose a high risk of interfering with pacemakers. patients with pacemakers need to inform their healthcare providers about their device before undergoing an mri scan. * **electrolysis tools:** used primarily for hair removal, these devices emit electromagnetic fields that can potentially interfere with pacemakers. patients are typically advised to avoid or use these tools cautiously. * **cell phones:** while modern smartphones are generally considered safe to use with pacemakers, keeping them at a recommended distance (generally about six inches) from the pacemaker site can help minimize any risk of interference. * **microwaves:** older microwave ovens were notorious for emi. however, advancements in technology have significantly reduced the risk. nonetheless, maintaining a prudent distance from older models during operation is wise. * **security scanners:** used at airports and other security-sensitive areas, these devices can emit electromagnetic fields. walking through them at a normal pace or requesting a manual check can reduce exposure for pacemaker users.

while these sources can contribute to emi, the actual risk to an individual largely depends on the strength of the electromagnetic field, the distance from the source, and the specific model and settings of the pacemaker. it is crucial for pacemaker users to consult with their healthcare providers for personalized advice and conduct daily activities with an awareness of environments that could pose risks. additionally, most pacemaker manufacturers provide detailed guidelines on how to navigate environments with potential emi sources.

What is Takayasu’s arteritis?

Correct Answer:
a less common form of vasculitis which affects large arteries. 


takayasu’s arteritis is an infrequent and chronic inflammatory disease of the large arteries, characterized primarily by the inflammation of the aorta—the main artery that carries blood away from the heart to the rest of the body—and its major branches. the inflammation leads to narrowing, occlusion, or dilation of the arteries, potentially disrupting blood flow and causing damage to organs and tissues.

the exact cause of takayasu’s arteritis is unknown, but it is believed to involve autoimmune processes in which the body’s immune system mistakenly attacks its own arteries. the condition is most commonly diagnosed in women, particularly those of asian descent, and typically presents in individuals who are under 40 years of age.

symptoms of takayasu’s arteritis can vary significantly depending on which arteries are affected and the extent of the disease. common symptoms include fatigue, weight loss, fever, night sweats, joint and muscle pain, and fainting. more severe complications can arise if the disease leads to reduced blood flow to critical organs. for instance, narrowed arteries to the arms or legs can cause pain and weakness, while involvement of the renal arteries can lead to high blood pressure and kidney damage.

diagnosis of takayasu's arteritis often involves a combination of clinical evaluation, blood tests to look for markers of inflammation, and imaging studies such as angiography, mri, or ct scans to directly visualize the condition of the arteries. early diagnosis and treatment are crucial to prevent serious complications.

treatment typically involves medications to reduce inflammation, such as corticosteroids and other immunosuppressive drugs. in some cases, surgical intervention may be necessary to repair or bypass affected arteries. the management of takayasu’s arteritis is usually a long-term process, focusing on controlling symptoms, reducing arterial inflammation, and managing any complications that arise.

as highlighted, takayasu’s arteritis is one of the conditions for which a coronary angiogram might be indicated. this diagnostic procedure can help visualize the coronary arteries and assess the impact of the arteritis on heart function, especially if there is a suspicion of decreased blood flow to the heart which could compromise myocardial performance.
