Comprehensive Exam Review & Practice Test
Question 1
A community health nurse is planning a health promotion initiative at a local
community center. Which activity is an example of primary prevention?
A. Providing free blood pressure screenings at a health fair
B. Administering the recombinant shingles vaccine to older adults
C. Teaching diabetic foot care to clients with peripheral neuropathy
D. Obtaining Mantoux tuberculin skin tests for healthcare workers
Correct Answer:
B. Administering the recombinant shingles vaccine to older adults
Rationale:
Primary prevention focuses on preventing disease before biological onset by
reducing susceptibility and exposure. Administering vaccines produces active
immunity against pathogens. Blood pressure checks and tuberculin skin tests
represent secondary prevention (screening), whereas diabetic foot care represents
tertiary prevention (reducing chronic complications).
Question 2
,A public health nurse is investigating a spike in new cases of pertussis in a school
district. Which epidemiological rate should the nurse calculate to evaluate the
speed of new disease spread?
A. Prevalence rate
B. Incidence rate
C. Case fatality rate
D. Crude mortality rate
Correct Answer:
B. Incidence rate
Rationale:
The incidence rate quantifies the number of new cases of a disease occurring
within an at-risk population over a specific timeframe. It directly reflects acute
disease transmission velocity. Prevalence measures all existing cases (new and
old), while case fatality calculates the proportion of deaths among confirmed
cases.
Question 3
A nurse is assessing an older adult client's environmental exposure history using
the "I PREPARE" mnemonic. Which question addresses the first "E" in the
mnemonic?
A. "What type of heating system is in your home?"
B. "What past military exposures did you experience?"
,C. "What are the environmental concerns in your neighborhood?"
D. "Do you have access to local health resources?"
Correct Answer:
C. "What are the environmental concerns in your neighborhood?"
Rationale:
In the "I PREPARE" environmental assessment framework, the first "E" represents
Environmental Concerns (neighborhood air quality, nearby industrial plants, waste
sites, and agricultural runoff). Heating systems address "Home," military duties
address "Past Work," and community agencies address "Resources and Referrals."
Question 4
A disaster response nurse performs mass-casualty triage using the Simple Triage
and Rapid Treatment (START) algorithm. A victim is non-ambulatory, breathing
24/min, has a palpable radial pulse, and cannot follow simple commands. Which
tag should the nurse assign?
A. Green (Minor)
B. Yellow (Delayed)
C. Red (Immediate)
D. Black (Expectant)
Correct Answer:
C. Red (Immediate)
Rationale:
Under START triage algorithms, non-ambulatory adult casualties with normal
, respirations (< 30/min) and intact radial perfusion who fail the mental status
assessment (unable to follow simple commands) are triaged as Red (Immediate).
This altered responsiveness signals acute neurological compromise requiring
urgent stabilization.
Question 5
An occupational health nurse conducts hearing screenings for factory workers
exposed to machinery noise. Which level of prevention does this activity
illustrate?
A. Primary prevention
B. Secondary prevention
C. Tertiary prevention
D. Primordial prevention
Correct Answer:
B. Secondary prevention
Rationale:
Secondary prevention emphasizes early disease detection through health
screening, periodic physical exams, and surveillance before clinical disability
occurs. Audiometric testing detects subclinical noise-induced hearing shifts.
Mandating hearing protection reflects primary prevention; speech therapy and
hearing aid fitting reflect tertiary rehabilitation.
