What types of equipment might a PCA need to help clients?

The correct choice highlights essential adaptive equipment that can significantly assist clients in their daily living activities. Wheelchairs, walkers, and shower chairs are specifically designed to enhance mobility, safety, and comfort for individuals who may have difficulties with movement due to age, disability, or injury.

Wheelchairs provide individuals with limited mobility a means to navigate their environment. Walkers offer additional support and stability during walking, allowing clients to regain some independence. Shower chairs facilitate safe bathing, reducing the risk of falls and ensuring that clients can maintain personal hygiene with dignity and safety.

While the other options may have their uses in various contexts, they do not directly address the fundamental needs of clients requiring personal care assistance. Computers and printers might be useful for administrative tasks but are not geared towards client mobility or safety. Similarly, televisions and entertainment systems cater to leisure but do not address any physical needs. Medical diagnostic tools are important in clinical settings but are not everyday equipment used by personal care assistants to support clients with daily living tasks. Thus, the focus on mobility-related equipment in the correct answer is crucial for the effective support of clients in a PCA role.
