Which of the following is a potential immediate effect of pesticide exposure?

Nausea that develops after three days, long-term respiratory issues, and persistent headaches are all indicative of delayed or chronic effects that arise from pesticide exposure rather than immediate reactions. Immediate effects of exposure to pesticides typically manifest rapidly, often within minutes to hours, as the body reacts to the chemicals.

Itchy skin at the point of contact is a classic example of an immediate effect, as it can occur almost instantaneously following exposure. This reaction is often due to the irritant properties of many pesticides, prompting a quick response from the body to protect itself from the irritant. Such localized skin reactions exemplify how certain types of pesticide exposure can immediately affect a person's health.
