A client is recovering from a fractured radius that occurred 8 weeks ago. In which stage of bone healing is the callus resorbed and transformed into bone?
Stage 4
Stage 3
Stage 5
Stage 1
The Correct Answer is A
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.

Correct Answer is ["A","B","E"]
Explanation
Choice A reason: Padding hard surfaces is a nursing intervention that decreases the risk of pressure injuries, because it reduces the pressure, shear, and friction on the skin and underlying tissues. Hard surfaces, such as bed rails, wheelchair arms, or footrests, can cause compression or irritation of the skin, especially over the bony prominences. Padding hard surfaces with foam, gel, or air cushions can provide protection and comfort for the client.
Choice B reason: Keeping head of bed (HOB) at or less than 30 degrees is a nursing intervention that decreases the risk of pressure injuries, because it prevents the sliding or shifting of the client in bed. Sliding or shifting can cause shear and friction on the skin, especially over the sacrum, coccyx, or heels. Keeping head of bed (HOB) at or less than 30 degrees can maintain the alignment and stability of the client in bed.
Choice C reason: Keeping head of bed (HOB) elevated to 75 degrees is not a nursing intervention that decreases the risk of pressure injuries, but rather one that increases the risk of pressure injuries. Elevating the head of bed (HOB) to 75 degrees can cause the client to slide or shift in bed, which can increase the shear and friction on the skin, as explained above. Elevating the head of bed (HOB) to 75 degrees can also increase the pressure on the sacrum, coccyx, or heels, which can impair the blood flow and oxygen delivery to the skin and tissues.
Choice D reason: Having client sit in wheelchair as much as possible is not a nursing intervention that decreases the risk of pressure injuries, but rather one that increases the risk of pressure injuries. Sitting in wheelchair as much as possible can cause prolonged pressure, shear, and friction on the skin and underlying tissues, especially over the ischial tuberosities, sacrum, coccyx, or heels. Sitting in wheelchair as much as possible can also reduce the mobility and activity of the client, which can affect the blood circulation and muscle tone.
Choice E reason: Placing pillows between bony surfaces is a nursing intervention that decreases the risk of pressure injuries, because it relieves the pressure, shear, and friction on the skin and underlying tissues. Bony surfaces, such as the ankles, knees, hips, or elbows, can cause compression or irritation of the skin, especially when they are in contact with each other or with the bed. Placing pillows between bony surfaces can provide cushioning and separation for the skin and tissues.
Correct Answer is A
Explanation
Choice A reason: Alcohol can trigger a gout attack because it increases the production and decreases the excretion of uric acid, which is the substance that causes inflammation and pain in the joints. Alcohol also dehydrates the body, which can worsen the symptoms of gout.
Choice B reason: Fruit juice is not a beverage that can trigger a gout attack. Fruit juice contains natural sugars and antioxidants, which may have a beneficial effect on the uric acid levels and the inflammation in the body. However, fruit juice should be consumed in moderation, as excess sugar intake can lead to weight gain and other health problems.
Choice C reason: Milk is not a beverage that can trigger a gout attack. Milk contains protein and calcium, which may help lower the uric acid levels and the risk of gout. Milk also has antiinflammatory properties, which may reduce the pain and swelling in the joints.
Choice D reason: Coffee is not a beverage that can trigger a gout attack. Coffee contains caffeine and antioxidants, which may have a protective effect on the uric acid levels and the inflammation in the body. Coffee also has a diuretic effect, which may help flush out the excess uric acid from the kidneys.
