When initiating oxygen per mask to a client who is short of breath, the nurse hears a loud hissing sound after inserting the flowmeter into the wall outlet. Which should the nurse do next?

Choice A reason: This is the best explanation as it describes the main goal of the log-rolling technique, which is to prevent twisting or bending of the spine. This is especially important for clients who have spinal injuries, surgeries, or disorders.

Choice B reason: Using two or three people is a part of the log-rolling technique, but it is not the purpose of it. It is a means to achieve the purpose of maintaining spinal alignment. It also ensures that the client is moved smoothly and gently.

Choice C reason: Working together can decrease the risk of back injury to the nurses, but it is not the purpose of the log-rolling technique. It is a benefit for the nurses, but not for the client. The nurse should focus on the client's needs and outcomes.

Choice D reason: Turning instead of pulling reduces the likelihood of skin damage, but it is not the purpose of the log-rolling technique. It is an advantage for the client, but not the main reason for using the technique. The nurse should explain how the technique affects the spine, not the skin.

Choice A reason: This is the correct instruction as it ensures that the injection is given in a well-perfused area with minimal risk of injury to major blood vessels or organs. The umbilicus should be avoided as it may harbor bacteria or cause discomfort.

Choice B reason: This is an incorrect instruction as it may result in a loss of medication or inaccurate dosing. The air bubble in the prefilled syringe should be left intact as it helps to seal the medication in the subcutaneous tissue and prevent leakage.

Choice C reason: This is an incorrect instruction as it may cause irritation or inflammation of the injection sites. The gluteal area should be avoided as it has a higher risk of hitting a nerve or blood vessel. The abdomen is the preferred site for low-molecular-weight heparin injections.

Choice D reason: This is an incorrect instruction as it may increase the risk of bleeding or bruising. The injection site should not be massaged or rubbed as it may dislodge the clot or damage the tissue.
