Final answer:
Nursing interventions that involve counseling a teenager to stop smoking and conducting a health fair for high blood pressure screening are examples of health promotion and preventive care on the primary level.
Step-by-step explanation:
A) A nurse counsels a teenager to stop smoking.
B) A nurse conducts a health fair for high blood pressure screening.
These two nursing interventions are examples of health promotion and preventive care on the primary level. By counseling a teenager to stop smoking, the nurse is promoting a behavior change that reduces the risk of developing smoking-related diseases in the future. Conducting a health fair for high blood pressure screening allows individuals to be screened early for high blood pressure, which can lead to early detection and management of the condition.
