Choice A rationale:

The client's statement is correct. Eliminating standing water around the home is an essential preventive measure for dengue fever as it helps in reducing mosquito breeding sites. Mosquitoes that transmit the dengue virus breed in stagnant water, so eliminating these breeding sites can reduce the risk of infection.

Choice B rationale:

The client's statement is correct. Seeking medical attention early when suspecting dengue fever is crucial because early detection and treatment can help prevent complications and severe forms of the disease. Dengue fever can progress rapidly, and timely medical intervention is necessary.

Choice C rationale:

The client's statement indicates a need for further teaching. Using insecticides indoors can be an important preventive measure to avoid mosquito bites, especially in areas where dengue is prevalent. Mosquitoes can enter homes through open doors and windows, and using insecticides can help reduce the risk of mosquito bites indoors.

Choice D rationale:

The client's statement is correct. Using mosquito repellent and wearing protective clothing are effective ways to avoid mosquito bites, especially during peak mosquito activity times. Dengue fever is transmitted through the bites of infected mosquitoes, and these preventive measures can help reduce the risk of infection.
