What phase of wound healing occurs at the time of injury and lasts about 35 days?

Choice A reason: Determine whether it is temporary or permanent is not the nurse's priority action for a client with compromised immunity, because it is not the most urgent and relevant. Determining whether the compromised immunity is temporary or permanent is an important assessment, but it should be done after ensuring the safety and infection prevention of the client. Compromised immunity can be temporary or permanent, depending on the cause, such as medication, disease, or genetic disorder.

Choice B reason: Take the client's vital signs every four hours is not the nurse's priority action for a client with compromised immunity, because it is not the most urgent and relevant. Taking the client's vital signs every four hours is an important monitoring, but it should be done after ensuring the safety and infection prevention of the client. Vital signs can indicate the general health status and the presence of infection or inflammation, such as fever, tachycardia, or hypotension.

Choice C reason: Teach the family members to receive the flu shot annually is not the nurse's priority action for a client with compromised immunity, because it is not the most urgent and relevant. Teaching the family members to receive the flu shot annually is an important education, but it should be done after ensuring the safety and infection prevention of the client. The flu shot is a vaccine that can protect the family members and the client from influenza, which can be a serious and potentially fatal infection for people with compromised immunity.

Choice D reason: Wash hands before entering the client's room is the nurse's priority action for a client with compromised immunity, because it is the most urgent and relevant. Washing hands before entering the client's room is a basic and essential infection prevention measure, which can protect the client from exposure to pathogens that can cause infection. People with compromised immunity have a weakened or impaired immune system, which makes them more susceptible and vulnerable to infection.

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.
