Kaji Review Questions (Main)

Revision as of 17:14, 1 October 2013 by Ostermayer (talk | contribs)

Amy Kaji MD PhD, faculty at Harbor-UCLA, has created an extraordinary set of Emergency Medicine review questions. These questions will live on WikEM with eventual incorporation into articles and CME modules. Please help format the questions for wiki quiz format.

Copy a question from the below documents and recreate it here with the wiki quiz markup. Then delete the question from the google document so that future users do not replicate the question.

The correct answer.

  • Feedback is text which is initially hidden, and then shown to the user when they submit the quiz for correction. Feedback typically serves the purposes of encouragement, explanation, congratulation and commiseration.
  • Feedback is set with all types by using a double vertical line || immediately after a response.
  • The pipes beginning the feedback section must be on a new line.
  • Unlike some other quiz systems, all feedback items are displayed on correction. With other quiz systems, the norm is to display the feedback only for those items which were selected by the user.
  • To try out the feedback effect, choose a response and click the correction button. The feedback will then appear.

How many minutes of apnea can a normal, healthy adult tolerate before oxygen desaturation to less than 90% occurs after administration of 100% oxygen for 3 minutes of normal, tidal volume breathing (preoxygenation)?

1 minute
3 minutes
5 minutes
8 minutes
10 minutes


Regarding testicular torsion (TT), which of the following statements is true

TT is the 3rd most common cause of a malpractice lawsuit in adolescent males 12-17 years old.
In the hands of an experienced emergency physician, it is possible to consistently and accurately differentiate TT from epididymoorchitis (EO) by physical examination alone.
The presence of a cremasteric reflex essentially rules out TT.
TT that present after 6 hours are not salvageable and no longer need to be evaluated in an emergent manner.
Color Doppler ultrasound is a consistently reliable tool for confirming the diagnosis of testicular torsion.


If time is insufficient for a full 3 minute preoxygenation phase, how many vital capacity breaths using high-flow oxygen can achieve oxygen saturations and apnea times that match or exceed those obtained with traditional preoxygenation?



Airway question – All of the following statements are TRUE about succinylcholine EXCEPT:

It is rapidly active, and it typically produces intubating conditions within 60 seconds of rapid intravenous bolus administration.
Its clinical duration of action is 6 to 10 minutes, and full recovery of normal neuromuscular function occurs within 15 minutes.
It is a negative chronotrope in children less than 10 years of age, and sinus bradycardia may ensue after administration.
Succinylcholine remains the agent of choice for RSI in acute burn, trauma, stroke, spinal cord injury, and intra-abdominal sepsis patients if intubation occurs less than 5 days after the onset of the condition.
It binds competitively to Ach receptors, preventing access to Ach and preventing muscular activity.
