Community and Public Health Nursing, Evidence for Practice 2nd Edition by Gail A. Harkness, Rosanna DeMarco Test Bank

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
