Step-by-step explanation:
In the prehospital treatment of a 64-year-old female experiencing chest pain and respiratory distress, the appropriate option would be Nitroglycerin. Nitroglycerin is a medication commonly used to treat angina, which is chest pain caused by insufficient blood flow to the heart. It helps to relax and widen blood vessels, improving blood flow and relieving chest pain. Given the patient's symptoms and medical history, nitroglycerin would be a suitable choice for prehospital treatment.
