Echo Pre-Test :: POCUS

Email

1) All of the following are standard views in a Basic Echo or BELS examination EXCEPT:

Parasternal long axis

Apical 4 chamber

Subcostal

Apical 5 chamber

2) What structure is marked 'A' in the image on the left?

Right Ventricle

Left Ventricle

Right Atrium

Left Atrium

3) Which of the following pathologies is not assessed on a Basic Echo or BELS examination?

Severe LV failure

Cardiac Tamponade

Aortic Regurgitation

Severe Hypovolaemia

4) Which of the following is TRUE regarding probe position in a Basic Echo examination?

To achieve the subcostal view the cardiac probe marker is orientated towards the patients right

A parasternal long axis view requires the cardiac probe marker to be pointed towards patient’s R shoulder

To achieve an apical 4 chamber view, the cardiac probe marker is pointed towards patient’s right eg 9 oclock position

A subcostal view is best performed with the patient laying flat

5) The image on the left shows:

Parasternal Long axis showing RV inflow/outflow

Parasternal Short axis at level of mitral valve

Parasternal Short axis showing ‘Mercedes benz’ sign of aortic valve

Parasternal Long axis showing tricuspid valve

6) On an Apical 4 chamber view which valves are easily visible?

Aortic and Mitral 

Mitral and Tricuspid

Tricuspid and Pulmonary

Tricuspid, Mitral and Aortic

7) Regarding assessment of the Left ventricle on basic echo, which of the following is INCORRECT?

An O shaped LV is normal in most patients

The RV is located closest to the probe/top of the screen in the PLAX view

D shaped LV is indicative of high RV pressure

LV function is difficult to assess in PSAX views

8) Which of the following is TRUE regarding IVC assessment?

It can be useful in confirming obstructive shock e.g. PE/tamponade

It is not helpful in assessing fluid status

It cannot be used in a critically unwell patient as they won’t be able to perform sniff test

IVC measurements cannot be interpreted in an intubated patient

9) What structure is marked 'A' on the image?

Tricuspid valve

Aortic valve

Mitral valve

Pulmonary valve

10) What is the role for Basic Echo or BELS in cardiac arrest?

Rule out major valve pathology

Check for any cardiac activity

To assess for regional wall motion abnormalities and activate cath lab accordingly

There is no role for BELS in cardiac arrest
