  • 2. 
    What is a sign or symptom of ICU acquired weakness?
    • A. 

      One week intubation

    • B. 

      Weight loss

    • C. 

      Prolonged bed rest

    • D. 

      All of the above

  • 3. 
    When would clinicians NOT be likely to suspect ICU-Acquired Weakness?
    • A. 

      Musculoskeletal patients experience abnormally slow recovery post orthopaedic surgery

    • B. 

      Neurology patients in the ICU experience a recovery of cognitive, memory, sensory function, yet are so weak as to appear quadriplegic

    • C. 

      While weaning patients off ventilation, clinicians notice respiratory muscle weakness (hindering return to spontaneous breathing) despite normal global recovery

    • D. 

      When symmetrical global motor deficiencies are present, but facial muscles are impaired

  • 4. 
    When is it important to investigate which type of ICU acquired weakness (polyneuropathy or myopathy) is present?
    • A. 

      While the patient is still sedated

    • B. 

      When recovery is faster than expected for ICU acquired weakness

    • C. 

      Every time ICU acquired weakness is diagnosed

    • D. 

      When recovery is slower than expected for ICU acquired weakness

  • 5. 
    Mr. Y was admitted to ICU 2/7 ago following a motor vehicle accident. He is sedated, physiologically and hemodynamically stable. He has been administered a neuromuscular block in conjunction with mechanical ventilation. Which intervention strategy would you recommend for Mr. Y at this point in time?
    • A. 

      Electromuscular stimulation

    • B. 

      Passive bedside cycle ergometry with passive stretching

    • C. 

      Patient is not ready for intervention at this point

    • D. 

      Interferential current therapy

  • 6. 
    Which of the following has not been demonstrated as an effect of electromuscular stimulation?
    • A. 

      Increased microcirculation of thenar muscles

    • B. 

      Improved oxidative capacity of muscles

    • C. 

      Stimulation of anabolic pathways

    • D. 

      Inhibition of Aβ pathways, inhibiting pain

  • 7. 
    Which of the following does not contribute to weakness in the ICU?
    • A. 

      Disruption of muscle synthesis and proteolysis

    • B. 

      Alterations in baroreceptor function

    • C. 

      Change of type I slow twitch fibres to type II fast twitch fibres

    • D. 

      Increased proinflammatory cytokines and inflammatory state

  • 8. 
    After spending one week in the ICU, how much muscle strength would you expect Mr. Y to have lost?
    • A. 

      1.5%

    • B. 

      3%

    • C. 

      4%

    • D. 

      7%

  • 9. 
    Which of the following was not identified by de Jonghe, B., et al 2009 as an obstacle to further research:
    • A. 

      There is a lack of commonly accepted diagnostic criteria for CINM

    • B. 

      Despite electrophysiology being a reliable method of detecting CINM, the clinical relevance of the abnormalities it detects remains unknown

    • C. 

      ICUAW occurs predominately in patients who require at least 5-7 days of mechanical ventilation. However, as the length of ventilation time cannot be predicted prior to treatment, many patients will be randomized for a trial despite only being at a low risk for developing CINM

    • D. 

      The mortality rate in patients that require 5-7 day of ventilation is high. Thus, assessment for ICUAW is challenging as it needs to be completed before their condition deteriorates

  • 10. 
    • A. 

      The effectiveness and quality of the interventions for CINM

    • B. 

      The mechanisms by which CINM causes dysfunction

    • C. 

      Treatment of CINM is an emerging area. Thus larger, long term, multicentre clinical trials are required to gain more evidence into the efficacy of CINM treatment and ICU mobilization as a whole

    • D. 

      Treatment of CINM with NMES and cycle ergometry
