A nurse is preparing to assist a client out of bed to a wheelchair following left knee surgery. The nurse should identify that which of the following images indicates the correct placement of the wheelchair?

A. "The lower end of the sling goes below the client's calves." The lower end of the sling should support the thighs and buttocks but typically does not extend below the calves. Positioning the sling incorrectly can cause discomfort or injury during the lift.

B. "The sides of the sling are for the client to hold on to." While some slings have loops for the caregiver to grasp, clients usually do not hold onto the sling sides during the lift, as this could interfere with safe handling and stability.

C. "This type of device is useful for a client who cannot assist." Mechanical lifts are specifically designed to safely transfer clients who have little or no ability to assist with moving. This reduces injury risk for both client and caregiver and ensures safe mobility.

D. "The device requires the client to use upper body strength." Mechanical lifts minimize the need for client effort, especially upper body strength. They are intended for clients unable to bear weight or assist, so reliance on client strength contradicts the device’s purpose.

A. An assistive personnel raises all four side rails of a client's bed before leaving the room: Raising all four side rails can be considered a form of restraint and poses a safety risk, especially if the client attempts to climb over them. It can increase the risk of falls and injury, particularly in confused or restless clients.

B. An assistive personnel places a weight-sensitive sensor mat on the mattress beneath a client's buttocks: This is not a safety hazard; it's a fall prevention measure. These sensor mats are designed to alert staff when a client attempts to get up, helping prevent falls in at-risk individuals.

C. A client who has bilateral wrist restraints has a capillary refill of less than 2 seconds:
A capillary refill of less than 2 seconds is within normal limits and indicates that circulation to the hands is intact. This suggests that the restraints are not too tight and do not currently pose a circulatory risk to the client.

D. A client who has a transcutaneous electrical nerve stimulation unit reports a buzzing sensation at the application site: A mild buzzing or tingling sensation is an expected and normal effect of a TENS unit. It does not indicate a malfunction or a safety issue unless it becomes painful or the skin shows signs of irritation or burns.
