Following are some simple mcqs from parks community medicine
1 Wt in kg is a
a discrete variable
b continuous variable
c nominal scale
d none
2 In India , death is to be registered within ------ days
a 3
b 7
c 11
d 14
3 A useful index to measure the lethality of an acute
infectious disease is
a attack rate
b incidence
c case fatality rate
d none of above
4 In an outbreak of cholera in a village of 2000
population, 20 cases have occurred and 5 died. Case
fatality rate is
a 1%
b 0.25%
c 5%
d 25%
5 All are true of standarised mortality ratio except a expressed as rate per year
b can be adjusted for age
c can be use for events other for death
d ratio of observed death to expected death
6 Incidence is difine as
a no. of cases existing in agiven population at agiven moment
b no. of existing in agiven period
c no. of casesnew occuring during a spesific period
d no. of old cases present during a spesific piriod in agiven
population
7 Secondary attack rate is calculated from
a minimum incubation period
b maximum IP
c average IP
d any of above
8 If a new drug is invented which prevent the mortality
from the diseases but does not affect the cure then
which of the following is true
a incidence will increase
b incidence will decrease
c prevalance will decrease
d prevalance will increase
9 In a stable situation
a incidence =prevalence +duration
b prevalence=incidence multiply duration
c incidence=prevalence multiply duration
d prevalence= incidence +duration
10 "CHERNOBYL" tragedy is an example of
a point sourse epidemic
b propagated epidemic
c modern epidemic
d continuous epidemic
11 Bhopal gas tegedy is example of
a slow epidemic
b continous epidemic
c point source epidemic
d propagated epidemic
12 Which is not an explanation for cyclic trend disease
a herd immunity variations
b envionmental conditions
c build up of susceptibles
d antigenic variations
13 The disese which is known as father of public health

14 Case control study is used for study of
a common diseases
b uncommon diseases
c rare diseases
d unknown diseases
15 Study of person who had already contrected the
disease is called
a case control
b cohort study
c control cohort
d none
16 case control study useful for
a finding a rare case
b finding multiple risk factors
c finding incidence rate
d finding morbidity rate
17 All of following are advantages of case control study
except
a cheaper
b less time consuming
c possible to study many diseases
d less chances of bias
18 Relative risk can be obtained from
a case study
b cohort study
c case control study
d experimental study
19 Relative risk could show an assocition between
a smoking and lung cancer
b OCP and pregnancy
c efficacy of 2 drugs
d attitude and endemic goitre
