In a medical emergency, what device commonly found in the office may contain latex?

The correct answer pertains to blood pressure (BP) cuffs being a common device used in medical settings that may contain latex. BP cuffs are often made with materials that include rubber, which traditionally has contained natural latex. This is particularly relevant for healthcare professionals to be aware of, as some patients may have latex allergies.

While plastic syringes and surgical masks can also have components that might trigger allergies, they are less likely to contain latex compared to BP cuffs. Plastic syringes typically use materials like polypropylene, which do not involve latex. Surgical masks are generally made from non-latex materials designed to be hypoallergenic. Oxygen tanks, on the other hand, do not commonly contain latex either, as the focus is on the tank's metal or composite materials.

Understanding the materials in commonly used medical devices is crucial for ensuring patient safety, particularly for those with known allergies. Hence, the prevalence of latex in blood pressure cuffs makes them the correct answer in this context.
