aaa1. Measuring the magnitude or frequency of a state of health determines the
characteristics of those who are at high risk. What is the primary method used to
measure the existence of states of health or illness in a population during a given time
period?aaa1. Measuring the magnitude or frequency of a state of health determines the
characteristics of those who are at high risk. What is the primary method used to
measure the existence of states of health or illness in a population during a given time
period?A) RateB) RatioC) Relative risk ratioD) Sensitivity
2. Calculation of rates provides the best indicators of the probability that a specific state
of health will occur. What is the correct formula for calculation of a rate?A)
B)
C) D)
3. Indices of the health of a community, region, or country include comparisons of
general mortality rates and maternal infant rates. What is the correct formula for the
maternal infant rate?A)
B)
C)
D)
4. A variety of rates can be calculated according to need, including incidence,
prevalence, adjusted, and specific rates. What is an adjusted rate?A) Statistical
procedure that removes the effects of differences in the composition of a population,
such as age, when comparing one to another.B) Measure of the probability that people
without a certain condition will develop that condition over a period of time.C) Measures
the number of people in a given population who have an existing condition at a given
point in time.D) Detailed rates that are calculated using the number of people in the
smaller subgroups of the population in the denominator.
5. A variety of rates can be calculated according to need, including incidence,
prevalence, adjusted, and specific rates. What rate measures the number of people in a
given population who have influenza at a given point in time?A) AdjustedB) IncidenceC)
PrevalenceD) Specific
6. The community health nurse is measuring the occurrence of chronic obstructive
pulmonary disease being investigated in the entire population. What rate does this
represent?A) AdjustedB) AttackC) CrudeD) Incidence
7. A variety of rates can be calculated according to need, including incidence,
prevalence, adjusted, and specific rates. What is the name of the rate represented when
detailed rates are calculated using the number of people in the smaller subgroups of the
population in the denominator?A) AdjustedB) IncidenceC) PrevalenceD) Specific
8. Specific rates calculated by person, place, and time provide the best description of a
health condition. What specific rate is represented by:
A) Age-specific mortality rateB) Cause-specific mortality rateC) Case fatality rateD)
Crude mortality rate
9. Before screening projects are undertaken, the sensitivity and specificity of screening
levels or test values should be carefully reviewed. What is sensitivity?A) The ratio of the
incidence rate in the exposed group and the incidence rate in the nonexposed groupB)
Ability of a test to correctly identify people who have a health problem; the probability of
testing positive if the health problem is truly presentC) Variations measured in hours,
days, weeks, or months; commonly found in outbreaks of infectious diseaseD) Ability of
a test to correctly identify people who do not have a health problem; the probability of
testing negative if the health problem is truly absent
10. Before screening projects are undertaken, the sensitivity and specificity of screening
levels or test values should be carefully reviewed. What is the correct formula for
sensitivity?A)
B)
C) D)
11. When there are unequal periods of observation for study subjects, it may be
necessary to use a person-time denominator in the calculation of incidence rates. What
does this technique measure?A) Incidence densityB) Prevalence rateC) Relative risk
ratioD) Specific rate
12. Incidence rates for groups exposed to a second-hand smoke are compared with the
incidence rates for people who are not exposed to second-hand smoke. What does this
measure?A) Incidence densityB) Prevalence rateC) Relative risk ratioD) Specific rate
13. What is the measure of the probability that people without a certain condition will
develop that condition over a period of time?A) Incidence densityB) Incidence rateC)
Relative risk ratioD) Specific rate
14. To provide more valid descriptions of the frequency of various states of health, it is
necessary to use ratios, proportions, or rates. There are several maternal and infant
rates that can be measured. Which calculation represents the fetal mortality rate?A)
B)
C)
D)
15. To provide more valid descriptions of the frequency of various states of health, it is
necessary to use ratios, proportions, or rates. There are several maternal and infant
rates that can be measured. Which calculation represents the perinatal mortality rate?A)
B)
C)
D)
