A nurse is caring for a client who has pneumonia.
The client’s oxygen saturation is 85%. What is the first action the nurse should take?

Choice A rationale
Locking the wheels of the bed and the wheelchair is an important safety measure when assisting a client to move from the bed to a wheelchair. However, this action alone is not sufficient. The nurse also needs to ensure the client’s safety during the transfer by using proper body mechanics and providing adequate support.
Choice B rationale
Elevating the bed to a position of comfort for the nurse is the correct action. This helps to ensure that the nurse can maintain proper body mechanics during the transfer, reducing the risk of injury to both the nurse and the client.
Choice C rationale
Getting the help of several staff members to lift the client is not typically necessary when transferring a client with generalized weakness from the bed to a wheelchair. With proper positioning and technique, one nurse can often safely assist the client with this type of transfer.
Choice D rationale
Placing the wheelchair at a 90° angle to the bed is not the recommended position when transferring a client from the bed to a wheelchair. Instead, the wheelchair should be positioned parallel to the bed or at a slight angle.

Choice A rationale
Vibration is a technique used in chest physiotherapy to increase the turbulence of the client’s exhaled air. It involves the use of manual or mechanical techniques to create vibrations in the chest wall during exhalation. This helps to loosen mucus in the airways and improve clearance of secretions.
Choice B rationale
Percussion, also known as chest clapping, is a technique used in chest physiotherapy to help loosen and mobilize secretions in the lungs. However, it does not specifically increase the turbulence of exhaled air.
Choice C rationale
Postural drainage involves positioning the client in specific ways to use gravity to assist in the removal of secretions from the lungs. While it can be beneficial in managing respiratory infections, it does not directly increase the turbulence of exhaled air.
Choice D rationale

Nebulization involves the use of a machine to create a mist of medication that the client inhales into the lungs. While it can be used to deliver medications to help manage respiratory infections, it does not increase the turbulence of exhaled air.
