What upright bilateral AC joints projection should be taken to best demonstrate the condition? - With weights at 180 cm - longer SID reduces magnification What area of the gown is considered part of the sterile field? The front of the gown, waist to shoulder What test must be performed first to ensure the validity of a mA linearity test results? - Timer accuracy - mA linearity assures that mA stations are accurate. The time and kVp accuracy must be verified prior to evaluate mA linearity What demonstrates minimal foreshortening of the femoral neck on on an axiolateral hip images? - The greater and lesser trochanters are on the same transverse level - this will verify that the CR is perpendicular to the femoral neck and the IR is parallel to the femoral neck What is the clinical indication for an HSG? - Infertility assessment - a Hysterosalpingiogram is used for infertility to demonstrate patency of uterine tubes Mr. Rogers presents with fixation devices protruding from the inferior aspect of his heel. The foot is flexed 70 degree. Calcaneus images have been ordered. How should the tech. direct the CR for the axial projection? - 60 degree cephalad - must increase the angle by 20 degree (40 + 20) to compensate for lesser dorsiflexion of the foot What will best demonstrate any medial or lateral displacement of a fracture of the ramus of the mandible? Axial AP (Towne) CAMRT - Test Review Questions With Answers | Updated 2024/2025 | 100% Correct Which projection would demonstrate air/fluid levels in the abdomen on an ICU patient who must remain supine? - Dorsal decubitus - this is correct based on the patient's condition; the horizontal beam will show air/fluid levels NICU CXR, what can be used to determine if rotation is present? Foreshortening of the clavicle on the side that the baby is rotated towards 00:0201:25 What are the most appropriate infection control measures for a patient with MRSA? - Gloves and gown - keeping any linen used in the patients room - gowns and gloves are only required because MRSA is transmitted by direct contact What should be done when inserting the rectal tip? - Ask the patient to take slow, deep breaths and insert the tip during exhalation - Exhalation promotes muscle relaxation, ensuring that the tip is easier to insert A patient with non-Hodgkin's lymphoma arrives for a follow up ct chest scan. What precautions should the technologist use? Protective precautions are employed to reduce the spread of infection to immueno compromised patients Which projection will best demonstrate the left axillary rib free of superimposition? Left posterior (ap) oblique Mr Toms, 47 years old, presents for a ct abdomen and pelvis scan with lower abdominal pain. On the images, the tech notices thickening of the bladder wall. Which condition should the tech suspect? Bladder carcinoma What action by the tech would be considered a breach of a patient's right to confidentiality? Discussing the exam findings with the patients spouse How does neutral rotation of the shoulder appear on an image? - Greater tubercle partly superimposed over the humeral head - Humeral head in partial profile - Slight overlap of humeral head on cavity While the tech is positioning an ambulatory patient for an erect abdominal examination, the patient becomes pale and starts to fall. What immediate action should be initiated? Assist the patient to the floor, this is the safest position for the patient The tech reviews a lateral scapula image and determines that it needs to be repeated. The medial border of the scapula is superimposed on the rib cage. What adjustments should the tech make for the repeat image? Increase the patients obliquity, this will superimposed both borders A portion of cancellous bone has a ct number of +445. If the WL is set to -100 and the WW is 650, what is the appearance of the cancellous? - White - Any structure with a CT number above +225 HU will appear white given the WW and WL What would be the most appropriate scanning practice for obtaining a CT image of a head while reducing radiation exposure to the patient's eyes? An axial scan with the gantry tilted to be parallel to the glabellomeatal line Which pathology will require the technologist to increase exposure factors? a. Ascites b. Emphysema c. Pneumothorax d. Bowel Obstruction Ascites Why wouldn't a tech need to increase exposure factors for a bowel obstruction? - Bowel obstruction results in an abnormal accumulation of air and fluid - The overall density of the tissue is decreased due to the large amount of trapped air in the bowel therefore resulting in a decrease in mAs What should the tech do to provide radiation safety for all personnel during an OR case? Provide lead aprons and place the image intensifier above the patient A tech is performing a hip exam on an inpatient who is unable to stand. The patient states that they need to urinate. How should the tech proceed? Offer a bedpan to the patient then complete the hip exam How would you correct a lateral elbow image if the radial head is distal to the coronoid process and the capitulum is located anterior to the trochlea? Elevate the distal forearm and repeat the image A patient was administered morphine and sent for a abdominal series. The patient reports right side pain, dizziness and weakness, but is otherwise alert. In addition to the AP supine image, what projection should the technologist perform? - Left lateral decubitus - This is safe for the patient and the intraperitoneal air will not be confused with the gastric bubble What is the best way to transfer a patient requiring spinal immobilization onto a radiographic table from a stretcher? Use a slider board A CT scan of the thorax has been requested to rule out metastatic disease. To demonstrate the required area, the scan must include from the apices to the level of what anatomical structure (s)? Adrenal glands should be included to demonstrate metastases if present A lateral view of the wrist demonstrates the ulna positioned anterior to the radius. How should the tech correct this positioning error? Decrease the external rotation of the wrist What adjustments should the tech make for a patient with emphysema? Decrease the mAs When performing a mobile radiographic procedure, which of the following would be best radiation safety practice for a tech? a. Wearing a protective lead apron and standing at least 2m away b. Standing at the right angle to the xray beam at least 2m away c. Standing behind the mobile xray unit at least 2m away d. Wearing a protective lead apron and standing at a right angle to the xray beam Wearing a protective lead apron and standing at least 2m away At what level should the top margin of the gonadal shield be placed on male patients for a supine abdomen? 2.5 cm inferior to the symphysis pubis What abnormal blood test results would contraindicate an exam requiring the injection of IV contrast media? - High creatinine levels - High BUN levels - Decreased GFR What is the mode of transmission for mumps? Droplet A patient with a walker arrives from the ER with a request for a consultation to rule out a mass in the apex of the chest.
