The overall pass rate for this question was 76 / 82 (92.7%).
A photograph of a blistered finger with a cellulitic hand is shown.
Although examiners liked the picture they found the questions did not allow
them to differentiate candidates’ performance.
They expected that the description would include an assessment of severity and
synthesis of a possible cause.
The management needed to be structured.
Failing candidates wrote very little in part a.

investigations have been performed.

FACEM VAQ Exam 2004.1 – Question 5


The overall pass rate for this question was 38 / 69 (55%).
This set of results was seen by the examiners as complex to interpret showing a
triple acid base disturbance with profound metabolic alkalosis, respiratory


alkalosis and metabolic acidosis associated with an elevated anion gap and
increased Aa gradient.
Examiners expected that at least 2 of the acid base disturbances would have
been detected and that a possible explanation in the context of the clinical setting
(such as salicylate poisoning) would be given.
Those who failed did not appreciate the complexity of the disturbance, stated the
obvious (eg hyponatremia) without interpreting or just regurgitated a list of
causes without linking these to the clinical scenario.
2004.1 VAQ 8
This 65 year old woman with diabetes presented one week after some minor trauma to
her right foot.

Overall pass rate for this question was 53 / 69 (76.8%).
An infected, necrotic foot ulcer is shown in the appended photograph.
This question demanded that the candidate not only describe the ulcer shown
but also describe all of the features of the leg and speculate on the likely
diagnosis and important differentials.
Investigations needed to address not just the ulcer itself but also search for
underlying cause and possible complications.
Candidates who failed usually neglected to address some or all of these issues.
2004.2 VAQ 1
A 60 year old man is brought to the emergency department with confusion, fever and
a painful left leg.
Question
a. Describe and interpret the photograph.
b. What further investigations would you perform in this man?

The overall pass rate for this question was 47 / 64 (73.4%).
A photograph shows an oedematous, discoloured and blistered leg
Examiners expected a description of the leg and then an interpretation which
took in to account the information provided in the stem.
More than one differential needed to be offered. Investigations needed to
consider not just the cause but also associated systemic problems like sepsis and
rhabdomyolitic renal failure.

Failing answers gave a poor description without any interpretation and simply
listed investigations without any evidence of thought of their application to this
patient.
2006.2 VAQ 5
An 6 year old girl has been brought to the emergency department with a fever of 38
degrees Celsius and a painful right eye.
Question

examination?

Clinical photograph of unilateral facial swelling and peri-orbital cellulitis.
The examiners felt that this was an adequate question but with low
discriminating capacity.
Pass/fail criteria were a detailed description of the involved region and a focused
examination related to the possible differential diagnosis.
2006.2 VAQ 3

The overall pass rate for this question was 44/57 (77.2%).
The examiners felt that this was a very appropriate question however few
candidates did very well.
A number of candidates passed part (a) but failed part (b). Pass/fail criteria were
based on a descriptive of the severity of the abnormalities, putting forward an
adequate interpretation (differential diagnosis) and a reasonable choice of
antibiotics.
2008.2 VAQ 8
A 47 year old man presents to your emergency department with a two day history of a
painful rash on the back of his neck.

Clinical photograph showing a large area of clustered vesicles with associated
erythema. Rash crosses the midline.
The examiners felt that this was a good question based on a high quality image.
Good answers identified a vesicular rash with a reasonable differential of
causes plus a focussed investigation of these causes.
Failed answers misdiagnosed non vesicular rashes (eg carbuncle).
It appeared that some candidates did not allocate their time as per the question
recommendation leading to inadequate detail in one or other section.

fever and vomiting. The following investigations have
been performed.
