Q

Edna Mode, 53F, has been admitted with an excruciatingly painful leg that started hurting 2 hours ago. You check her leg and it appears pale and cold. You can not locate her dorsalis pedis pulse.

Given her likely diagnosis, what form of imaging would be most appropriate?

  1. MRI of her leg
  2. CT angiography
  3. Doppler ultrasound scan
  4. ABPI
  5. Xray chest
A

Answer C

Doppler ultrasound should happen first. CT angiography may also be useful, but doppler may be done at the bedside and is more accessible. ABPI may also be useful, but it should be done after the Dopple. It is also not a mode of imaging.

34
Q

Q74.) An 85-year old man is admitted into hospital for pneumonia. This is his 4th episode in the past 6 months. He has a past medical history of COPD and states that he is becoming increasingly breathless despite the pharmacological therapy he is on. He finds it difficult to do daily tasks he normally could without getting breathless. He is an ex-smoker. His last 3 ABG’s have demonstrated O2 <7.3kpa and his resting O2 saturation is 89%. Which is an eligible factor to start long-term oxygen therapy?

  1. Recurrent episodes of pneumonia
  2. O2 saturation of 89%
  3. Worsening breathlessness despite pharmacological therapy
  4. ABG results of O2 <7.3kpa
  5. Loss of daily function tasks due to breathlessness
A

Answer: D

The requirements for LTOT are that you must be a non-smoker and your pO2 is consistently below 7.3kPa or your pO2 is below 8kPa if you have cor pulmonale or you have consisten O2 saturations below 88%. This patient’s O2 saturation is 89%. Answers A, C and E would not be indicators to start LTOT.

35
Q

Q75.) You are called to see an 83-year old patient on the ward as the nurses are concerned she has not opened her bowels in the past 5 days. The patient has a pmhx of Alzheimer’s dementia and is on the ward recovering from a recent pneumonia infection, but appears well. On abdominal examination you feel a palpable mass in the Lower left quadrant. You decide to perform a PR examination on the patient with a chaperone and you notice a relaxed anal spinter tone with some hard stool in the rectum. How would you manage this patient?

  1. Stimulant laxative
  2. Oral macrogol
  3. Glycerol suppository
  4. Enema
  5. Oral lactulose
A

Answer: B

This patient has hard stool faecal impaction and according to NICE the first line management is to prescribe an oral macrogol laxative. Using a stimulant laxative would not work as the stool needs softening. An enema may not work as the stool is hard so it may fall out.
