MCQ Paper No.73rd July 2017 by admin Please select True or False for the following questions. 1. With regards to rib fractures as a consequence of trauma:a. Contusions lead to ventilation-perfusion mismatch and, as a result, type II respiratory failure True False b. Increasing age is associate with increased morbidity and mortality True False c. Opioids should be started as a first line for all rib fracture patients True False d. Flail chest is an indication for operative fixation True False e. FVC is reduced 12 months later in comparison to control with operative fixation True False 2. With regards to statistics: a. Ordinal data is continuous True False b. When r=0 there is no correlation between the two sets of paired interval data True False c. The mode is the central datum when all the data are arranged in numerical order True False d. Negatively skewed data has a longer upper tail when plotted in graphical form True False e. For positively skewed data mode<median<mean True False 3. With respect to interpretation of ECGs: a. Isolated ST elevation in V5, V6, III and aVL represents a lateral MI in a patient with chest pain True False b. The normal PR interval is between 120-200 ms True False c.
