There are several environmental hazards affecting human health. What would be one way the nurse could reduce the effects of a physical hazard on humans?
A) Encourage the use of ear plugs during NASCAR races.
B) Encourage the use of microwave ovens in place of gas ranges.
C) Remove standing water to reduce the mosquito population.
D) Remove dead plants in gardens to prevent destruction of adjacent plants.
Ans: A
Physical hazards to health include radiation, lead, other heavy metals, and noise. Biologic hazards can be infectious agents, insects, animals, and plants. Use of earplugs will reduce noise and damage to hearing. Encouraging microwave use is counterproductive to reduction of physical hazards. Reducing the mosquito population and removing dead plants are examples of preventing biologic hazards, not physical hazards.
