A. Tertiary prevention
B. Secondary prevention
C. Primary prevention
D. Quaternary prevention
Answer: C
Rationale: Primary prevention focuses on preventing the initial occurrence of a disease or
injury. Immunizations are a classic example as they build immunity before exposure. This
level of intervention aims to reduce the incidence of disease within a population.
2. Which of the following activities should a nurse include as part of secondary prevention for
lead poisoning?
A. Educating families about paint safety
B. Assisting with home lead abatement programs
C. Referring a child for chelation therapy
,D. Screening children for blood lead levels

symptoms occur. This intervention helps limit the impact of the condition through prompt
management.
