Which of the following is a respiratory issue related to pesticide exposure?

Shortness of breath and coughing are indeed respiratory issues that can occur as a result of pesticide exposure. Pesticides can irritate the respiratory system, leading to symptoms such as difficulty breathing and persistent coughing. These reactions are due to the inhalation of pesticide particles or fumes, which can cause inflammation, bronchial constriction, or other respiratory distress. Recognizing these symptoms is crucial for identifying potential pesticide-related health effects and ensuring that proper safety measures are in place to mitigate such risks.

In contrast, the other symptoms mentioned, such as nausea and vomiting, increased appetite, and dry skin, do not specifically pertain to respiratory issues. While they can indeed be side effects of pesticide exposure, they do not relate to the respiratory system and thus are not the correct choice in the context of this question.
