Nurses should opt for latex-free gloves in the following scenarios: 1. Patients with Latex Allergies: Always use latex-free gloves when treating patients known to have latex allergies to prevent allergic reactions. 2. High-Risk Procedures: During procedures that involve exposure to bodily fluids or sharp instruments, nitrile gloves are preferable due to their puncture resistance. 3. Frequent Glove Changes: In situations where gloves need to be changed frequently, such as in caregiving tasks, vinyl gloves can be a cost-effective choice.
