CT Domain 1: Patient Care Welcome to your CT Domain 1: Patient Care 1. CT: Patient Care A patient with a known allergy to iodinated contrast media requires a contrast-enhanced CT scan. What is the most appropriate initial action for the technologist to take? Proceed with the scan without contrast Administer a steroid and antihistamine premedication protocol Use a non-iodinated contrast agent Cancel the scan immediately None 2. CT: Patient Care When positioning a patient for a CT scan of the abdomen, which of the following practices is essential to ensure optimal image quality? Asking the patient to hold their breath during the scan Elevating the patient's legs Having the patient drink a cup of water Placing a pillow under the patient's head None 3. CT: Patient Care During a CT examination, a patient suddenly exhibits signs of a contrast media reaction. What is the first step that should be taken? Continue monitoring the patient's vital signs Stop the contrast media injection immediately Complete the scan as quickly as possible Administer an antihistamine to the patient None 4. CT: Patient Care In CT imaging, what is the primary reason for using a lower IV contrast flow rate in a patient with a small bore peripheral IV? To reduce the risk of extravasation To decrease the total dose of contrast To prolong the duration of the scan To enhance the visualization of vascular structures None 5. CT: Patient Care What is the most appropriate action if a patient develops hives during a CT scan with IV contrast? Immediately administer epinephrine Observe the patient for more severe symptoms Stop the contrast injection and notify a physician Continue the scan to quickly finish the procedure None 6. CT: Patient Care For a patient with severe claustrophobia, which of the following strategies is most effective in facilitating completion of a CT scan? Increasing the speed of the scan Providing detailed explanations of the procedure Administering a sedative, if prescribed Using a larger bore CT scanner None 7. CT: Patient Care When a non-English speaking patient requires a CT scan, what is the most appropriate way to communicate the procedure details to ensure understanding? Use simple English words and gestures Provide written instructions in English Use a professional medical interpreter Ask a family member to translate None 8. CT: Patient Care A patient scheduled for a CT scan of the chest has a heart rate of 110 bpm. What consideration should be taken regarding the scan timing? Delay the scan until the heart rate decreases Administer a beta-blocker under physician guidance Adjust the scan parameters to accommodate for the high heart rate Proceed with the scan without any modifications None 9. CT: Patient Care When obtaining informed consent for a CT procedure involving contrast, what information must be explicitly communicated to the patient? The cost of the procedure The technical details of the scanner Potential risks and side effects of the contrast media The qualifications of the radiologist None 10. CT: Patient Care For a patient with a history of renal failure, what is a critical consideration before administering iodinated contrast for a CT scan? Evaluating the patient's creatinine levels Checking the patient's blood pressure Confirming the patient's allergy history Reviewing the patient's medication list None 11. CT: Patient Care In the context of a CT scan, why is it important to verify the patient's history of diabetes, especially if they are taking metformin? Metformin can interfere with the absorption of IV contrast Patients on metformin have an increased risk of contrast-induced nephropathy Metformin can cause a rare, but serious condition called lactic acidosis after receiving IV contrast Diabetes increases the risk of allergic reactions to contrast media None 12. CT: Patient Care What is the most important action to take when a patient experiences a vasovagal reaction during a CT scan? Elevate the patient's legs and monitor vital signs Administer oxygen immediately Continue the scan to quickly complete the procedure Provide fluids intravenously None 13. CT: Patient Care When performing a CT scan on a pediatric patient, what is the most important consideration to ensure patient safety? Use the highest possible dose for clarity Apply adult scanning protocols for consistency Utilize sedation for all pediatric patients Adjust the radiation dose based on the child's size None 14. CT: Patient Care In CT imaging, how should the technologist respond if a patient expresses concern about radiation exposure? Dismiss the patient's concerns as the dose is always minimal Explain the risk-benefit ratio and how the scan is justified Suggest they refuse the scan if they are worried Offer to perform the scan without radiation None 15. CT: Patient Care For a patient with a known contrast media reaction who requires a CT scan, what is a key step in the pre-scan preparation? Obtain a detailed allergy history Increase the contrast dose to overcome the allergy Avoid using any contrast, regardless of the type Ensure emergency resuscitation equipment is readily available None 16. CT: Patient Care When a patient with a pacemaker is scheduled for a CT scan, what is the most important consideration? Immediately cancel the scan Verify the type of pacemaker and its compatibility with CT imaging Increase the scan speed to reduce exposure time Place a lead shield over the pacemaker None 17. CT: Patient Care How should a CT technologist proceed when a patient reports nausea during a contrast-enhanced scan? Continue the scan at a faster pace Stop the injection of contrast and assess the patient's condition Administer an antiemetic immediately Ignore the complaint as it is a minor side effect None 18. CT: Patient Care What is the best practice for a CT technologist when a patient reports pain during a contrast media injection? Continue the injection while monitoring the patient closely Stop the injection and quickly finish the scan without contrast Immediately stop the injection and evaluate the injection site for extravasation Increase the flow rate to shorten the injection duration None 19. CT: Patient Care In the event of a contrast extravasation, what is the first action the CT technologist should take? Elevate the affected limb Apply a cold compress to the site Continue scanning to assess the extent of extravasation Immediately stop the contrast injection None 20. CT: Patient Care How should a CT technologist address a situation where a patient cannot remain still due to anxiety? Proceed with the scan to avoid delays Use physical restraints Offer reassurance and consider anxiolytic premedication if prescribed Increase the scan speed regardless of image quality None 1 out of 20 Time is Up!
