What precautions should the nurse use when caring for a client with generalized urticaria?

When caring for a client with generalized urticaria, standard precautions are the most appropriate. Standard precautions are designed to prevent the transmission of infections and protect both the healthcare worker and the patient. These precautions include practices such as hand hygiene, wearing gloves when exposure to body fluids is possible, and using appropriate barriers to reduce the risk of infection.

Generalized urticaria, which is typically a hypersensitivity reaction resulting in hives, does not necessitate additional isolation measures like airborne, droplet, or contact precautions, as these are specifically for conditions that are transmitted through respiratory droplets, in the air, or by direct contact with an infected person or contaminated surfaces, respectively. Therefore, utilizing standard precautions adequately protects against any potential infectious agents and is the correct approach in this case.
