ARRT CI Exam Questions & Answers 2024/2025

ARRT CI Exam Questions & Answers 2024/2025 About how long does a coronary angiography last? - ANSWER-30 to 60 minutes. A coronary angiography is used to check the blood flow from the arteries into the heart. A contrast material is inserted through at catheter and the patient is then x-rayed to check how well the contrast material is flowing. The doctor can then check for any blockages. The procedure will last only about 30 to 60 minutes. The catheter is first inserted into ______ for a pulmonary angiogram? - ANSWER-Vein Which of the following is not a type of pacemaker? a. Triple atrium pacemaker b. Single pacemaker c. Dual pacemaker d. Biventricular pacemaker. - ANSWER-Triple atrium pacemaker Which of the following is the total volume for carotid angiography in the Arch? a. 30-50ml b. 11-12ml c. 4-6ml d. 8-9ml - ANSWER-30-50ml An EKG is performed for which of the following reasons? a. Determine unexplained chest pain b. Determine the reason for headache c. Determine changes in mood d. Determine stomach pain - ANSWER-a. Determine unexplained chest pain Ondansetron (Zofran) is a medication used to treat or prevent nausea and vomiting. What is the proper IV dose of this medicine for the average adult patient? - ANSWER-4mg, repeat x 1 if necessary Regarding the coagulation profile, what is the normal time range for bleeding time? - ANSWER-2-9 minutes Normal time range for Prothrombin time in adult - ANSWER-10 - 13 seconds Normal time range for Partial thromboplastin time in adult - ANSWER-22 - 35 seconds. Normal time range for Thrombin time in adult - ANSWER-18 - 25 seconds Which of the following is done by sending an electric shock to the heart using electrodes? a. Angioplasty b. Cardioversion c. Shunt detection d. Ventricular volume measurement - ANSWER-Cardioversion Which of the following is the typical field size (cm) for the Anteroposterior calf vessels view of a lower limb angiogram? a. 50 b. 30 c. 20 d. 40 - ANSWER-d. 40. For the Anteroposterior calf vessels view of a lower limb angiogram, the typical parameters are: Contrast volume (mL): 10 - 20 Injection rate (mL/s): 5 Frame rate (frames per second): 1 Field size (cm): 40 Inject delay (s): 0 X-ray delay (s): Increase as necessary Which size guide wire is typically used with balloons for peripheral interventions? a. 0.035 inch b. 0.018 inch c. 0.021 inch d. 0.001 inch - ANSWER-a. . 035 inch The small guide wires are typically. 018 inch. They may be as small as .014 inch. The larger guide wires used with balloons are .035 inch. Why would a right ventriculogram be performed? - ANSWER-To determine if there is and why there is an abnormal blood flow on the right side of the heart A right heart ventriculography evaluates images of both the right atrium and right ventricle. It is performed to determine if there is and why there is an abnormal blood flow on the right side of the heart. Abnormal results include: weakened pumping functions, abnormal pressures, abnormalities in the right side of the heart valves, abnormalities in the right atrium, and abnormal connections between both sides of the heart. Risks include: cardiac arrhythmias, cardiac tamponade, embolism, heart attack, infection, hemorrhage, kidney damage, stroke, and low blood pressure. This procedure can also be done with coronary angiograms. To prepare for a ventriculography, patients should be instructed to do what? - ANSWER-Not to eat or drink 6 to 8 hours before the procedure A ventriculography is used to take images of the chambers of the heart. During the procedure contrast dye is injected into the chambers of the heart. The contrast dye is able to show if there are any problems with the shape and size of the heart. To have good images of the heart chambers patients should not eat or drink 6 to 8 hours before the procedure. Ondansetron is a medication used to reduce nausea and vomiting. What type of medication is this? a. Benzodiazepine b. Benzodiazepine antagonist c. Antiemetic d. Opioid. - ANSWER-c. Antiemetic. Drugs used to treat or prevent nausea and vomiting are called antiemetics. Ondansetron (Zofran) and Promethazine are examples of antiemetics. What type of arrhythmia is caused by a disorganized and erratic firing of impulses from the heart's ventricles a. Sinus node dysfunction b. Atrial flutter c. Ventricular tachycardia d. Ventricular fibrillation. - ANSWER-d. Ventricular fibrillation Arrhythmia is also known as dysrhythmia. It is an irregular heartbeat. There are several different types. Some types include: premature ventricular contractions, premature atrial contractions, atrial flutter, ventricular fibrillation, sinus node dysfunction, ventricular tachycardia, and paroxysmal supraventricular tachycardia. The most inner part of the guidewire is called the what? a. The central wire b. The distal tip c. The pit d. The core. - ANSWER-d. The core. A guidewire is made of three essential parts: the core, the distal tip and the outer covering. The most inner part of the guidewire is known as the core and extends through the shaft of the entire wire. It is the stiffest part of the wire, creating a sense of stability, allowing it to be steered and 'guided'. A single-chamber pacemaker can have a lead in the lower chamber of the heart, also known as what? - ANSWER-The ventricle In a stent, there is a scaffold provided by _______. a. Lumen b. Catheter c. Wire mesh d. None of the above. - ANSWER-c. Wire mesh Stents provide a scaffold to support the vessel walls. This is made of wire mesh. It keeps the lumen open and helps prevent plaque from building up. What is in the dye used for angiograms? a. Water b. Alcohol c. Iodine d. Oxygen - ANSWER-c. Iodine Of the following central alpha - agonists, which has a typical dosage range of 8 - 32 mg? a. Clonidine hydrochloride b. Guanabenz acetate c. Guanfacine hydrochloride d. Methyldopa. - ANSWER-Guanabenz acetate 8 - 32 mg (2 times per day) Pacemakers do what? a. Collect high electrical impulses sent from the heart b. Collect low electrical impulses sent from the heart c. Send low electrical impulses to the heart muscle. d. Send high electrical impulses to the heart muscle - ANSWER-c. Send low electrical impulses to the heart muscle Pacemakers perform the action of sending low electrical impulses sent from the heart. It is used to maintain a correct heart rate. Their main job is to prevent the heart rate from being too slow. It is composed of a pulse generator and leads. Which of the following would be administered if a patient develops an embolism? a. Heparin b. Lasix c. Atropine d. Amiodarone - ANSWER-a. Heparin Complications in a coronary angiogram are most likely to occur in which of the following? a. Males b. Adolescents c. Elderly people d. Infants - ANSWER-Elderly people A coronary angiogram is used to see inside of the coronary arteries. Coronary arteries give the heart oxygen enriched blood. Some complications include arrhythmias, kidney damage, blood clots, and low blood pressure. Arrhyt...........
