Nursing Concepts Q&A with Rationale |

1. During a disaster mass casualty incident, a nurse identifies a victim with an open
pneumothorax and severe respiratory distress. Which triage tag color should be assigned to
this individual?
A. Red tag
B. Yellow tag
C. Green tag
D. Black tag
Correct Answer: A
Expert Explanation: The red tag indicates an immediate priority for victims with life-
threatening injuries who have a high probability of survival if treated immediately. An open
pneumothorax causes immediate respiratory compromise and requires urgent
intervention to maintain airway and breathing. This classification is a critical component of
the START triage system used by community health nurses in disaster response.
2. A community health nurse is investigating an outbreak of Pertussis in a local elementary
school. Using the epidemiological triangle, which factor represents the ‘agent’?
A. The local climate and humidity levels
,B. The school environment and classroom layout
C. The unvaccinated status of the students
D. The Bordetella pertussis bacteria
Correct Answer: D
Expert Explanation: The agent in the epidemiological triangle refers to the biological,
chemical, or physical factor whose presence or absence is necessary for a disease to occur.
In this scenario, Bordetella pertussis is the specific biological pathogen responsible for the
illness. Understanding the relationship between the host, agent, and environment is
essential for determining effective control measures during an outbreak.
3. Which of the following activities performed by a home health nurse best exemplifies
primary prevention?
A. Assisting a client with range-of-motion exercises following a stroke
B. Performing a blood glucose check for a client with known Type 2 Diabetes
C. Teaching a young couple about the importance of childhood immunizations
D. Conducting a dressing change on a chronic pressure ulcer
Correct Answer: C
Expert Explanation: Primary prevention focuses on health promotion and the prevention
of the initial occurrence of disease or injury. Education regarding immunizations aims to
provide immunity before exposure to pathogens, thereby preventing illness entirely. This
,differs from secondary prevention, which involves screening, and tertiary prevention,
which focuses on rehabilitation.
4. A nurse is conducting a windshield survey of a new neighborhood. Which of the following
observations provides the most relevant data regarding the community’s potential health
risks?
A. The presence of modern recreational parks and walking trails
B. The abundance of fast-food restaurants and lack of grocery stores
C. The age and architectural style of the residential homes
D. The location of the local police and fire departments
Correct Answer: B
Expert Explanation: The prevalence of fast-food outlets combined with a lack of access to
fresh produce indicates a food desert, which is a significant social determinant of health.
Such environments increase the community’s risk for chronic conditions like obesity,
hypertension, and diabetes. Windshield surveys allow nurses to observe physical and social
environment factors that impact public health outcomes.
5. A nurse is working with a migrant farmworker who presents with muscle twitching,
abdominal cramps, and excessive salivation. The nurse should suspect exposure to which of
the following?
A. Lead-based paint chips
B. Organophosphate pesticides
, C. Carbon monoxide fumes
D. Asbestos fibers
Correct Answer: B
Expert Explanation: Migrant farmworkers are at high risk for pesticide toxicity due to
frequent exposure in the fields. Symptoms like muscle twitching and salivation are classic
signs of organophosphate poisoning, which inhibits acetylcholinesterase. Occupational
health nursing for this population requires a high index of suspicion for agricultural
chemical exposures.
6. Which nursing intervention represents secondary prevention for a community with high
rates of tuberculosis (TB)?
A. Educating the community on respiratory hygiene and cough etiquette
B. Administering the Mantoux tuberculin skin test to high-risk residents
C. Assisting TB-positive patients with their daily medication adherence
D. Providing nutritional supplements to patients recovering from TB
Correct Answer: B
Expert Explanation: Secondary prevention involves the early detection and screening of
disease to limit disability and prevent further spread. The Mantoux skin test identifies
individuals who have been infected with the bacteria but may not yet show symptoms. This
allow for early intervention and public health tracking to protect the broader community.
