1. You are reviewing ketamine sedation with an adult EM resident who tells you that he routinely uses ketamine and propofol for sedated reductions at his home institution. All of the following are properties associated with propofol EXCEPT:
a) Anxiolysis
b) Analgesia
c) Anti-emetic
d) Hypotension
2. You are reviewing the double-blinded randomized controlled trial by Shah et al comparing the performance of ketamine/placebo vs ketamine/propofol for ED procedural sedation. In the study, 69 patients were randomized to the ketamine/placebo group and 67 to the ketamine/propofol group. 8 patients had post-procedural emesis in the ketamine/placebo group compared to only 1 in the ketamine/propofol group. The best approximation of the number needed to harm for post-procedural emesis based on this study is:
a) 2
b) 8
c) 10
d) 12
3. You are reviewing the results of this same study, comparing total sedation time, efficacy and adverse effects forprocedural sedation with ketamine/placebo vs ketamine/propofol, and find that the results are reported as non-normally distributed continuous variables and presented as medians with interquartile ranges (IQR). Which of the following statistical tests would the authors have used to analyze this type of study?
a) Mann Whitney U test
b) Kruskal Wallis test
c) Two-sample t-test
d) One way ANOVA
4. You are the med control physician and have received multiple calls for similar patients with asthma and respiratory distress at 4 different referring hospitals: Merritus, Frederick Memorial, Howard County General, and City Hospital. Which of the following is the most accurate listing of these hospitals in order of closest to farthest distance from CNMC?
a) Frederick Memorial, Howard County, City Hospital, Merritus
b) Howard County, Merritus, Frederick Memorial, City Hospital
c) Frederick Memorial, Howard County, City Hospital, Merritus
d) Howard County, Frederick Memorial, Meritus, City Hospital
b) Howard County, Merritus, Frederick Memorial, City Hospital
c) Frederick Memorial, Howard County, City Hospital, Merritus
d) Howard County, Frederick Memorial, Meritus, City Hospital
5. A 5 week old M is brought to the ED by his parents after turning blue and limp after a feeding at home. He is now well appearing, afebrile, and back to baseline with a normal physical exam. All of the following are true regarding ALTEs (Apparent Life Threatening Events) except:
a) ALTE is a diagnosis of exclusion
b) ALTE has not been shown to be associated with SIDS
c) Prematurity is a risk factor for recurrent clinically significant ALTE
d) Diagnostic evaluation in ALTE should be guided by history, examination and initial evaluation
