Which action should be taken immediately if a client feels faint during transfer?

When a client feels faint during a transfer, assisting the client to lay down is crucial for their safety and well-being. This action helps prevent a fall and allows the client to regain stability. Laying down can promote blood flow to the brain, reducing the risk of syncope (fainting) and ensuring that the client does not sustain any injuries from falling.

It's important to ensure the client is comfortable and secure during this process. By positioning them flat or in a reclined posture, you support their body's physiological needs in an emergency situation, allowing time for their condition to improve.

Other options, while they may seem helpful, do not provide the same immediate benefit in preventing a fall or addressing the client's sudden onset of feelings of faintness. Reporting to the nurse or providing water can wait, as the priority is to stabilize the client first. Having the client sit down might not be sufficient if they are already feeling faint, as this still leaves them at risk of falling if they lose consciousness.
