After a series of heavy rains, the nurse in the local health department increases the water monitoring of the local beach because several upstream creeks flow into it. Why did the nurse increase the water monitoring?
1. Monitor the water purity of the creek flow.
2. Make sure that no debris is swept into the water.
3. Make sure that tidal currents are safe for swimming.
4. Monitor the water for potential microorganisms that could prevent safe swimming.
Answer: 4
Explanation: 4. After heavy rains, water is stirred up, especially when other water sources drain into the water, such as from upstream creeks. This can impair the water quality, making it unsafe for swimming due to a potential increase in microorganisms. Tidal currents do not require water monitoring. Routine monitoring of the creek's water purity is important, but it is more of a priority after heavy rains, which can stir up the bottom when the water level rises. Monitoring water quality has no bearing on whether debris is swept into the water.
