What technique is used to communicate an accurate medication list given to a pt in the emergency room who is then transferred to the icu?
Medication reconciliation
What is the equation for Odds Ratio
(A/C)/(B/D)
What is the equation for Relative Risk
(A/A+B)/(C/C+D)
What is the equation for Attributable Risk
(A/A+B) - (C/C+D)
What is the equation for Relative Risk Reduction
1-RR
RR = (A/A+B)/(C/C+D)
What is the equation for Absolute Risk reduction
ARR = (C/C+D) - (A/A+B)
What is the equation for Number Needed to Treat
NNT = 1/ARR
What is the equation for Number Needed to harm
NNH = 1/AR

Which test can be used to determine if there is different in the mean between three or more groups of normally distributed populations?
ANOVA
What is the immunological sequence of events in the mechanism of an asthma attack?
initial stimulation causes CD4 Th2 cells to release IL-4 to stimulate IgE production and IL-5 to activate eosinophils.

Paternalism - when patient/surrogate decision maker are deemed unreasonable or dangerous to patient.
What is are the advantages and disadvantages of Case-control studies
advantage - require few subjects, can be used to study rare diseases
disadvantages - make it difficult to make conclusions about correlations
What is the technique:
testing to identify sample RNA:
RNA is cut into fragments by endonucleases, electrophoresed on gel and transferred to a filter. filter is soaked in denaturant and exposed to DNA probe
