NR442/NR 442 Exam 3 V3 | Community
Health Nursing Q&A with Rationale |
Chamberlain University
1. A nurse is triaging victims of a chemical plant explosion. Which of the following color tags
should the nurse assign to a client who has a small skin laceration and is walking around the
site?
A. Red
B. Green
C. Yellow
D. Black
Correct Answer: B
Expert Explanation: Clients who are ambulatory and have minor injuries are classified as
‘walking wounded’ and assigned a green tag. This indicates that their care can be delayed
significantly while more critical victims are treated. The nurse must still monitor these
individuals periodically to ensure their status does not deteriorate.
2. A community health nurse is calculating the prevalence of tuberculosis in a specific county.
Which of the following information is required for this calculation?
A. Number of new cases reported during the last year
B. The mortality rate associated with tuberculosis in the county
,C. Total number of existing cases in the population at a specific time
D. The percentage of the population vaccinated against the disease
Correct Answer: C
Expert Explanation: Prevalence refers to the total number of existing cases (both old and
new) in a population at a specific point in time. Incidence, by contrast, only counts new
cases occurring within a defined period. This metric helps the nurse understand the total
burden of disease on the community resources.
3. A nurse is planning a primary prevention program for adolescents regarding substance
abuse. Which of the following activities should the nurse include?
A. Conducting random drug testing at the local high school
B. Referring students to a local rehabilitation facility
C. Providing counseling for students who have a history of drug use
D. Teaching students about the risks of using tobacco and alcohol
Correct Answer: D
Expert Explanation: Primary prevention aims to prevent the onset of disease or injury
before it occurs through education and health promotion. Teaching students about the
risks of substance use is a proactive measure to discourage the behavior initially. Activities
like drug testing or referral for treatment fall under secondary or tertiary prevention
categories.
,4. A community health nurse is conducting an environmental assessment using the ‘I
PREPARE’ mnemonic. What does the ‘P’ in ‘I PREPARE’ represent?
A. Population density
B. Poverty level
C. Personal protective equipment
D. Past work history
Correct Answer: D
Expert Explanation: The ‘I PREPARE’ mnemonic is a tool used by nurses to identify
potential environmental health risks. The ‘P’ stands for ‘Present work’ and the second ‘P’
stands for ‘Past work’ to identify occupational exposures. This assessment helps the nurse
correlate health symptoms with environmental or workplace toxins.
5. Which of the following describes the role of the Occupational Safety and Health
Administration (OSHA)?
A. Setting and enforcing standards for workplace safety and health
B. Conducting research on new workplace safety technologies
C. Providing individual health insurance to workers in high-risk jobs
D. Lobbying for the privatization of occupational health services
Correct Answer: A
, Expert Explanation: OSHA is a federal agency responsible for establishing and enforcing
regulations to ensure safe and healthful working conditions. They conduct inspections and
can issue fines to employers who fail to comply with safety standards. This agency is
distinct from NIOSH, which focuses primarily on research and education.
6. A nurse is working with a client who is homeless and has a chronic skin infection. Which of
the following is the priority intervention?
A. Finding a permanent housing solution for the client
B. Assessing the client’s access to clean water and wound care supplies
C. Teaching the client about the importance of daily hygiene
D. Assisting the client with a job application
Correct Answer: B
Expert Explanation: When working with vulnerable populations like the homeless, the
nurse must first assess barriers to following a treatment plan. Without access to clean
water or basic supplies, teaching hygiene is ineffective and wound healing is impossible.
Immediate physiologic needs and safety take priority over long-term goals like housing or
employment.
7. A nurse is providing education to a family about lead poisoning prevention. Which of the
following instructions should the nurse include?
A. Wet-mop floors and windowsills rather than dry-dusting
B. Vacuum carpets frequently using a standard vacuum cleaner
