1. A community health nurse is planning a health fair to provide blood pressure screenings for
local residents. Which level of prevention is being implemented?
A. Primary Prevention
B. Quaternary Prevention
C. Tertiary Prevention
D. Secondary Prevention
Correct Answer: D
Explanation: Secondary prevention involves early detection and intervention to prevent
the progression of a disease. Blood pressure screenings are a form of health screening
intended to identify individuals with hypertension early. This approach allows for prompt
treatment and management before complications arise.
2. When applying the epidemiological triad to a case of influenza, which of the following is
considered the ‘agent’?
A. The healthcare facility
B. The infected patient
C. The influenza virus
D. Cold weather conditions
,Correct Answer: C
Explanation: The agent in the epidemiological triad is the animate or inanimate factor that
must be present or lacking for a disease or condition to develop. In this scenario, the
influenza virus is the biological agent responsible for the illness. The patient is the host, and
the environment encompasses the external factors like weather.
3. A nurse is using the I-PREPARE mnemonic to assess a client’s environmental health history.
What does the ‘E’ in I-PREPARE stand for?
A. Environmental justice
B. Environmental concerns
C. Emergency preparedness
D. External factors
Correct Answer: B
Explanation: The I-PREPARE mnemonic is an environmental health assessment tool used
by nurses. The ‘E’ specifically stands for environmental concerns, which prompts the nurse
to ask about issues like air or water quality. This tool ensures that all potential
environmental hazards are systematically evaluated during the patient interview.
4. A community health nurse is investigating an outbreak of food poisoning after a local
church picnic. Which step should the nurse take first in the epidemiological investigation?
A. Establish the existence of an outbreak
B. Interview those who attended the picnic
, C. Implement control measures to stop the spread
D. Perform laboratory tests on food samples
Correct Answer: A
Explanation: The first step in an epidemiological investigation is always to confirm that an
outbreak is actually occurring. This involves comparing the current number of cases to the
expected baseline for that community. Only after the outbreak is established can the nurse
proceed to descriptive epidemiology and intervention.
5. A school nurse is providing education to students about the importance of wearing bicycle
helmets. This is an example of which level of prevention?
A. Primary Prevention
B. Secondary Prevention
C. Tertiary Prevention
D. Direct Intervention
Correct Answer: A
Explanation: Primary prevention aims to prevent the onset of injury or illness before it
occurs. Educating children on safety measures like helmet use reduces the risk of head
injuries during accidents. This intervention targets the entire population of students
regardless of their current health status.
