The nurse is teaching a client with debilitating rheumatoid arthritis about home safety. Which statement should the nurse include?

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.

Choice A reason: Popping bursae from standing is not the cause of the grating sound. Bursae are fluidfilled sacs that cushion the joints and reduce friction. Popping bursae may produce a snapping or clicking sound, but not a grating sound.

Choice B reason: A herniated disk in the diseased joint is not the cause of the grating sound. A herniated disk is a condition where the soft inner part of the intervertebral disk bulges out through a tear in the outer layer. A herniated disk may cause pain, numbness, or weakness, but not a grating sound.

Choice C reason: Pieces of bone and cartilage floating is the cause of the grating sound. Osteoarthritis is a degenerative joint disease that causes the breakdown of the cartilage and bone in the joints. Pieces of bone and cartilage may detach and float in the joint space, causing a grating sound when the joint moves.

Choice D reason: Years of an autoimmune process is not the cause of the grating sound. An autoimmune process is a condition where the immune system attacks the body's own tissues. An autoimmune process may cause inflammation, swelling, or damage to the joints, but not a grating sound.
