Hospital Medicine Point of Care Ultrasonography

Question 1: You are getting ready to place a central line in the right internal jugular vein. You are standing by the patient’s head on his right side, scanning the right IJ vein in transverse plane with the probe marker pointed medially. Which of the following is the correct image when scanned in the procedural orientation convention?

Question 2: Which of the following statements is TRUE:

Every ultrasound probe has a marker on one side of transducer. Signals from the marked side of the probe are wired to be displayed on the side of the right side of the screen.
In cardiology image orientation convention, the reference is the sonographer. The probe marker should be pointing to the right and the screen marker – to the left.
In radiology imaging convention, structures closer to the probe (more superficial in the body) will appear on the left side of the screen and the structures further away from the probe (deeper in the patient body) – on the right.
When scanning in transverse plane in the procedural imaging convention, the simulated view is similar to that of a CT where the observer is looking from the patient’s feet towards the patients’ head.

Question 3: Which of the following statements is TRUE:

When imaging aorta and the IVC in cross-section, the aorta will appear on the left side of the screen if imaged in radiology convention, but on the right side of the screen if imaged in cardiology convention.
When imaging the IVC in the long axis the entrance of the IVC into the RA will appear on the left side of the screen if imaged in the radiology convention and on the right side of the screen if imaged in the cardiology convention.
In cardiology convention the probe marker is towards the patient’s head or towards the patient’s right.
When imaging the left kidney in radiology convention in a supine patient, the probe marker should be pointing down into the bed (towards the patient’s back).
