Deck 2: Image Acquisition

Question 1

The practitioner is attempting to visualize a deep structure. Which is the best choice to improve the ability to view the deep structure?

A) Use a lower transducer frequency.
B) Use a spectral doppler ultrasound.
C) Use a higher transducer frequency.
D) Use a color flow doppler ultrasound.

Answer 1

A

Question 2

The color flow doppler ultrasound is a form of pulsed-wave Doppler, where the echoes are assigned a color. This improves visualization of motion, such as that of blood flow.

A) A-mode
B) B-mode
C) M-mode
D) TM-mode

Answer 2

B

Question 3

M-mode is sometimes referred to as TM-mode.

A) The linear transducer probe.
B) The sector transducer probe.
C) The curved linear transducer probe.
D) The transvaginal (TV) transducer probe

Answer 3

D

Question 4

The practitioner is developing policies and procedures for ultrasound equipment maintenance. When determining the best means to clean and disinfect the transducers, which of the following should the practitioner do?

A) Perform an Internet search for policies and procedures from other clinics.
B) Refer to the AUIM (American Institute of Ultrasound in Medicine) instructions.
C) Review the material safety data sheets (MSDS) for disinfectants available in the clinic.
D) Research the CDC (Centers for Disease Control and Prevention) infection control advice.

Question 5

Which scan plane divides the body into anterior and posterior segments?

A) The sagittal plane.
B) The median plane.
C) The transverse plane.
D) The longitudinal plane.

Question 6

The ultrasound student is instructed to manipulate the transducer by rocking. Which action should the student complete?

A) Place pressure on the probe to compress the body part.
B) Change just the angle of the ultrasound in the long axis.
C) Move the transducer in the long axis to the desired area.
D) Shift the transducer either clockwise or counterclockwise

Question 7

The practitioner is doing an obstetric ultrasound exam on a woman who is approximately 24 weeks pregnant, weighs approximately 325 pounds (147 kg), and demonstrates abdominal obesity. Which technique is the best approach to improve visualization of the desired structures?

A) Scan using a lateral approach over the lower abdomen.
B) Use a rocking motion over the uterus until it is in view.
C) Place as much pressure as needed over the central abdomen.
D) Move the transducer in a clockwise motion until view is clear.

Question 8

When considering the thermal effects of ultrasound examination, which situation places the greatest thermal effects on the fetus during an obstetric ultrasound examination?

A) The woman demonstrates an obese abdomen.
B) The woman demonstrates a thin abdominal wall.
C) The practitioner is using the B-mode for examination.
D) The practitioner is viewing the fetal cardiac blood flow.

Question 9

Which action demonstrates the ALARA (as low as reasonably achievable) principle is being used by the practitioner?

A) The highest power tolerated by the patient is used.
B) The thermal index is displayed on the output screen.
C) The practitioner works quickly to acquire the images needed.
D) The pulsed Doppler is the first approach used for examination.

Question 10

The practitioner notes the image quality on the ultrasound exam is poor with several artifacts. Which is the first action the practitioner should take to address these image quality issues?

A) Ensure adequate coupling gel has been applied.
B) Send the machine for repair by the manufacturer
C) Check the clinic's preventative maintenance records.
D) Change to a different transducer and compare images.
