Why is it important to save ultrasound images in the correct place? For billing purposes only To ensure images are associated with the correct patient and encounter Because the AMA requires it for all imaging To make the worklist shorter

What should you do if you are unsure which ultrasound study to order for your patient? Order all possible scans Skip the order and scan anyway Use a combo order that includes multiple studies Ask the patient what they want

Where do you find the link to your completed ultrasound study for documentation in Epic? In the procedure section of the note In the imaging history In the Butterfly Enterprise system In the lab results

For educational scans, where should you document your image findings? In the patient’s chart In the Butterfly Enterprise system On a USB drive On the ultrasound machine only

What should you do to uniquely identify an educational scan? Use the patient’s full name Use a random number or unique identifier Use your own name Leave the field blank

What is the purpose of combo orders in the ultrasound workflow? To make billing easier To reduce the number of scans needed To speed up the ordering process To include multiple imaging studies in a single order for undifferentiated patients

Which organization recommends specific guidelines for emergency ultrasound credentialing decisions? ACEP AMA SAEM AHA

What is the term used for an unidentified ultrasound scan that is not linked to a patient chart? Educational Scan Solo Scan Phantom Scan Guided Scan

What is the preferred ultrasound probe for gallbladder imaging? Linear Curvilinear Phased array Endocavitary

What is the normal maximum diameter of the common bile duct (CBD) measured from inner wall to inner wall? 2mm 4mm 6mm 10mm

Which of the following is a classic finding of cholelithiasis on ultrasound? Hyperechoic structure in the gallbladder with posterior shadowing Homogeneous liver parenchyma Absent gallbladder lumen Edge artifact

What is considered pathologic for gallbladder wall thickness on ultrasound? > 1mm >3mm >5mm >7mm

What is the “double barrel sign” seen on ultrasound? A dilated common bile duct sitting on top of the portal vein Two gallstones in the gallbladder Two layers of the gallbladder wall Hepatic artery on top of the common bile duct (CBD)

How many views of each kidney are typically obtained during a renal ultrasound? 1 2 3 4

Which of the following best describes hydronephrosis? Dilated renal cortex Dilation of the collecting system of the kidney Thickened bladder wall Enlarged prostate

What is considered a normal post-void residual bladder volume? Less than 50 mL Less than 100 mL Less than 150 mL Less than 200 mL

What is a useful technique to distinguish normal anatomy from pathology in musculoskeletal ultrasound? Scan only the affected side Use maximum pressure on the probe Scan in one plane Scan the contralateral side for comparison

What is the “dead zone” in musculoskeletal ultrasound? An area of poor resolution immediately under the probe The deepest part of the image A region of artifact caused by bone The area outside the field of view

Which of the following best describes the appearance of bone on ultrasound? Hypoechoic with posterior enhancement Anechoic with reverberation artifact Hyperechoic with posterior acoustic shadowing Isoechoic with no shadowing

What is anisotropy in the context of musculoskeletal ultrasound? A difference in echogenicity due to the angle of insonation An artifact caused by movement A type of probe defect A color Doppler artifact

What is the “double contour sign” seen in crystal arthropathy? Hyperechoic band over cartilage Hypoechoic ring around tendon Anechoic fluid in joint space Hyperechoic bone cortex

What is the preferred ultrasound probe for most superficial soft tissue evaluations? Linear Curvilinear Phased array Endocavitary

What is one technique to improve imaging of superficial structures and combat the dead zone? Increase probe pressure Use a lower frequency probe Skip scanning in two planes Use a water bath or standoff pad

Which ultrasound appearance is most consistent with an abscess? Hypoechoic or anechoic fluid collection with posterior acoustic enhancement Hyperechoic structure with shadowing Homogeneous subcutaneous tissue Normal muscle striations

What is the quintessential ultrasound feature of cellulitis? Well-defined fluid collection Hyperechoic bone cortex Loss of distinct tissue architecture and blurred margins Cobblestoning

What should you do before performing a procedure on a suspected abscess? Perform an I&D Confirm with ultrasound that it is really an abscess Skip color flow evaluation Do not use a standoff pad

What is the recommended angle for needle insertion during ultrasound-guided peripheral IV placement? 90 degrees 45 degrees 30 degrees 15 degrees

According to the LAMP sequence, what does the "A" stand for? Anesthetize Align the probe and center it on screen Assess the vein Advance the catheter

How can you best distinguish a vein from an artery during ultrasound-guided IV placement? Veins are always larger than arteries Arteries are always deeper than veins Veins collapse easily with pressure and are non-pulsatile Veins are always more echogenic

Which of the following is NOT a recommended step in the ultrasound-guided IV placement process? Always use a longitudinal (long axis) approach Use a checklist or mnemonic like LAMP Keep the needle tip in sight at all times Confirm placement with saline flush and visualization of microbubbles

What is the main reason to use a longer angiocatheter for deeper vessels? To reduce pain To increase the risk of infiltration To make the procedure faster The actual distance traveled is about 1.5x what is seen on the screen

What is the hallmark ultrasound finding for a DVT in the lower extremity? The vein is compressible The vein is non-compressible The artery is pulsating The vein is hyperechoic

Which of the following is a common mimic of DVT on ultrasound? Lymph node Muscle strain Skin abrasion Bone fracture

Which technique can help distinguish a lymph node from a vein with a thrombus? Use a lower frequency probe Increase pressure until the structure collapses Only scan in one plane Add color Doppler and look for flow through the structure
