A nurse is preparing to administer aspirin 650 mg PO. The available medication is aspirin 325 mg tablets. How many tablets should the nurse administer?

Choice A rationale
While it’s true that a nasal cannula allows the patient to remove it for a while when it gets uncomfortable, this is not the primary reason for using a nasal cannula. The main purpose of a nasal cannula is to deliver oxygen.
Choice B rationale
A nasal cannula delivers the low concentration of oxygen that the patient needs. It is designed to provide a specific amount of oxygen, and the flow rate can be adjusted as needed.

Choice C rationale
While a nasal cannula does deliver a specific concentration of oxygen, it does not do so constantly. The amount of oxygen delivered can vary depending on the patient’s breathing rate and depth.
Choice D rationale
A nasal cannula does not deliver the highest concentration of oxygen possible. Other devices, such as non-rebreather masks, can deliver higher concentrations of oxygen.

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.
