Question
1 of 6

Question1
Scanning technique and gastric sonoanatomy

Which of the following statements regarding scanning technique and sonoanatomy are correct? Select all that apply.
- Start with a sagittal scan in the epigastric area
- Place the patient in the left lateral decubitus position
- An empty or low content stomach typically has sonographicall visible internal folds
- An empty or low content transverse colon typically has sonographically visble internal folds
- Scanning in the supine position alone may underestimate gastric content leading to a “false negative” test
- A low frequency probe is preferred for all subjects except small children under 40 kg
Correct

Question2
Gastric content assessment

Which of the following statements regarding gastric content assessment are correct? Select all that apply.
- The type of gastric content can be determined qualitatively with sonography
- Semi-sitting position is a suitable alternative to right lateral decubitus position to assess gastric content of the antrum
- The gastric content is overestimated in the supine position
- It is clinically important to differentiate between thick fluid and solid
Correct

Question3
Sonographic assessment of empty stomach vs. clear fluid

Which of the following statements regarding sonographic assessment of empty stomach vs. clear fluid is correct?
- When the stomach is empty, the antrum is collapsed and either round or ovoid in cross-section
- Sometimes an empty stomach carries a high risk of aspiration
- Clear fluid appears hyperechoic (white) on ultrasound
- Ultrasound can accurately differentiate between different types of clear fluid (e.g. water vs. clear gastric secretions)
- Clear fluid in the antrum never carries a high risk of aspiration
Correct

Incorrect

4 of 6

Question4
Assessment of thick fluid/solid in the stomach

Which of the following statements regarding assessment of thick fluid/solid are correct? Select all that apply.
- Thick fluid or solid in the stomach only carries a risk of aspiration when the volume is > 1.5 mL/kg
- Thick fluid or solid gastric content suggests a non-fasted state and a high risk of aspiration
- Thick fluids (eg milk or yoghurt) appear hyperechoic and homogenous
- Solid particulate content appears hyperechoic and homogenous
- Solid particulate content appears heterogeneous with large and small particles
Correct

Incorrect

Question5
Assessment of gastric volume

Which of the following statements regarding gastric volume assessment are correct? Select all that apply.
- The gastric volume is best assessed in the supine position
- The cross-sectional area (CSA, in cm2) correlates linearly with squared volume of gastric fluid
- The estimate of gastric fluid volume depends on CSA and age
- The estimate of gastric fluid volume is independent of age
- No visible antral fluid in neither supine nor RLD position, correlates with negligible gastric fluid volume
Correct

Incorrect

Question6
Interpretation of findings

Which of the following statements regarding interpretation of findings are correct? Select all that apply.
- An empty stomach compatible with fasting can present either as truly empty or a low volume <1.5 mL/kg of clear fluid content
- An empty stomach compatible with fasting can present either as truly empty or a low volume <1.5 mL/kg of clear or thick fluid content
- Risk of aspiration always has to be assessed both qualitatively and quantitatively
- The gastric volume model discussed has been validated for all non-pregnant adults of any BMI
Correct

Incorrect
