What is an example of a client's primary defense to infection?

Choice A reason: Shearing or friction is the force that caused the injury, because it occurs when the skin and underlying tissues move in opposite directions, such as when the client slides down in bed. Shearing or friction can damage the blood vessels and reduce blood flow to the skin, resulting in tissue ischemia, necrosis, and ulceration.

Choice B reason: Pressure or gravity is not the force that caused the injury, because it occurs when the skin and underlying tissues are compressed between a bony prominence and an external surface, such as when the client lies on his back. Pressure or gravity can impair blood flow and oxygen delivery to the skin, resulting in tissue damage and ulceration.

Choice C reason: Chemical or pressure is not the force that caused the injury, because it occurs when the skin is exposed to a substance that causes irritation, inflammation, or corrosion, such as when the client has a wound dressing that contains an antiseptic or a topical agent. Chemical or pressure can damage the skin barrier and increase the risk of infection and delayed wound healing.

Choice D reason: Twisting and bending is not the force that caused the injury, because it occurs when the skin and underlying tissues are stretched or distorted, such as when the client twists his ankle or bends his knee. Twisting and bending can cause sprains, strains, or tears of the ligaments, tendons, or muscles.

Choice A reason: "Because it is easy to digest." is not the best response by the nurse. This is not a valid reason for giving protein supplements to a client with a bed sore. Protein supplements may or may not be easy to digest depending on the type and amount of protein and the client's digestive system. The ease of digestion is not the main goal of protein supplementation.

Choice B reason: "If you don't like it, you don't have to take it." is not the best response by the nurse. This is a dismissive and unprofessional response that does not address the client's question or concern. Protein supplements are prescribed for a reason and the client should be educated on the benefits and risks of taking or refusing them. The nurse should also respect the client's preferences and choices and offer alternatives if possible.

Choice C reason: "These supplements have nothing to do with your wound." is not the best response by the nurse. This is a false and misleading statement that contradicts the evidencebased practice of wound care. Protein supplements have a lot to do with wound healing as they provide the essential nutrients for tissue repair and regeneration. Protein deficiency can impair wound healing and increase the risk of infection and complications.

Choice D reason: "Protein has amino acids that promote wound healing." is the best response by the nurse. This is a factual and informative statement that explains the rationale for giving protein supplements to a client with a bed sore. Protein is composed of amino acids, which are the building blocks of cells and tissues. Amino acids are involved in various processes of wound healing, such as collagen synthesis, angiogenesis, and immune response. Protein supplementation can enhance wound healing and prevent protein malnutrition.
