A nurse is providing oral hygiene for an unconscious client. What is the priority nursing intervention?

Choice A reason: Stage 4 is the remodeling stage of bone healing, which occurs from 6 to 12 weeks after the fracture. In this stage, the callus, which is a mass of fibrous tissue and cartilage that forms around the fracture site, is gradually resorbed and replaced by mature bone. The bone becomes stronger and more compact and regains its original shape and function.

Choice B reason: Stage 3 is the callus formation stage of bone healing, which occurs from 2 to 6 weeks after the fracture. In this stage, the granulation tissue, which is a soft tissue that fills the fracture gap, is replaced by a callus that bridges the fracture ends. The callus is composed of fibroblasts, chondroblasts, and osteoblasts that produce collagen, cartilage, and bone matrix. The callus stabilizes the fracture and prepares it for remodeling.

Choice C reason: Stage 5 is not a valid stage of bone healing. There are only four stages of bone healing: stage 1 is the inflammatory stage, stage 2 is the reparative stage, stage 3 is the callus formation stage, and stage 4 is the remodeling stage.

Choice D reason: Stage 1 is the inflammatory stage of bone healing, which occurs from the time of the fracture to 3 to 5 days after the fracture. In this stage, the blood vessels around the fracture site are ruptured and form a hematoma, which is a blood clot that surrounds the fracture ends. The hematoma triggers an inflammatory response that involves the release of cytokines, growth factors, and inflammatory cells that initiate the healing process. The hematoma also provides a scaffold for the granulation tissue to grow.

Choice A reason: Wearing a gown is the correct answer, because it is the appropriate PPE for contact precautions, which are required for clients who have MRSA. MRSA is a type of bacteria that is resistant to many antibiotics and can cause serious infections in the skin, blood, lungs, or other organs. MRSA can be transmitted by direct or indirect contact with the infected wound or contaminated surfaces. Wearing a gown can protect the nurse's clothing and skin from exposure to MRSA.

Choice B reason: Wearing sterile gloves is not the correct answer, because it is not the appropriate PPE for contact precautions, which are required for clients who have MRSA. Sterile gloves are used for sterile procedures, such as inserting a catheter or changing a dressing, not for routine assessments, such as checking the pulse. Wearing sterile gloves can be wasteful and unnecessary, and it does not provide adequate protection from MRSA.

Choice C reason: Wearing a PAPR mask is not the correct answer, because it is not the appropriate PPE for contact precautions, which are required for clients who have MRSA. PAPR stands for powered airpurifying respirator, and it is a type of mask that filters the air and provides positive pressure to the wearer. PAPR masks are used for airborne precautions, which are required for clients who have diseases that can be spread through the air, such as tuberculosis or measles, not for clients who have MRSA.

Choice D reason: Wearing a surgical mask is not the correct answer, because it is not the appropriate PPE for contact precautions, which are required for clients who have MRSA. Surgical masks are used for droplet precautions, which are required for clients who have diseases that can be spread through respiratory droplets, such as influenza or pertussis, not for clients who have MRSA.
