The client with rheumatoid arthritis is having her rheumatoid factor (RF) drawn while she is having a flareup of the disease. Which result is seen in clients with rheumatoid arthritis?

Choice A reason: A 44yearold prescribed antibiotics for pneumonia is not at the greatest risk for pressure injury development, because he or she does not have any major risk factors for pressure injury. Pressure injury is a localized damage to the skin and underlying tissues caused by pressure, shear, friction, or moisture. Antibiotics for pneumonia do not directly affect the skin integrity or blood circulation, nor do they impair the mobility or sensation of the client.

Choice B reason: A 26yearold bedridden client with a fractured leg is at a high risk for pressure injury development, but not the greatest, because he or she has only one major risk factor for pressure injury. Bedridden status is a major risk factor for pressure injury, because it causes prolonged pressure on the bony prominences, such as the sacrum, heels, or hips, which can impair blood flow and oxygen delivery to the skin and tissues. However, the client's age, fracture, and mobility may mitigate some of the risk, as he or she may have better skin elasticity, wound healing, and ability to reposition.

Choice C reason: A 65yearold with hemiparesis and incontinence is at the greatest risk for pressure injury development, because he or she has multiple major risk factors for pressure injury. Age is a risk factor for pressure injury, because it causes decreased skin elasticity, thickness, and vascularity, which can affect the skin's resilience and repair. Hemiparesis is a risk factor for pressure injury, because it causes reduced mobility, sensation, and muscle mass, which can affect the client's ability to reposition, feel pain, and maintain tissue perfusion. Incontinence is a risk factor for pressure injury, because it causes moisture, irritation, and infection of the skin, which can weaken the skin barrier and delay wound healing.

Choice D reason: A 78yearold requiring assistance to ambulate with a walker is at a moderate risk for pressure injury development, but not the greatest, because he or she has only one major risk factor for pressure injury. Age is a risk factor for pressure injury, as explained above. However, the client's ambulation and assistance may reduce some of the risk, as he or she may have less pressure, shear, and friction on the skin and tissues, and more blood circulation and oxygen delivery.

Choice A reason: Once the tissue has necrosed from high pressure, it does not regenerate is the best explanation, because it describes the mechanism and outcome of glaucoma. Glaucoma is a condition that causes increased intraocular pressure, which damages the optic nerve and the retina, the tissues that are responsible for transmitting and processing visual information. Once these tissues are necrosed, or dead, they do not regenerate, or grow back, resulting in irreversible vision loss.

Choice B reason: Glaucoma always leads to permanent blindness is not a good explanation, because it is inaccurate and pessimistic. Glaucoma does not always lead to permanent blindness, but rather to progressive vision loss that can be prevented or slowed down with early diagnosis and treatment. Glaucoma can cause peripheral vision loss, tunnel vision, or blind spots, but not necessarily complete blindness.

Choice C reason: Once retinal detachment occurs, it does not return to its normal state is not a good explanation, because it is irrelevant and misleading. Retinal detachment is a condition that occurs when the retina separates from the underlying layer of blood vessels, which can cause vision loss or blindness. However, retinal detachment is not caused by glaucoma, nor is it a common complication of glaucoma. Retinal detachment can sometimes be repaired with surgery, depending on the extent and duration of the detachment.

Choice D reason: Once bacterial infection has caused damage, the tissue does not regenerate is not a good explanation, because it is incorrect and confusing. Bacterial infection is not a cause or a consequence of glaucoma, but rather a separate condition that can affect the eye. Bacterial infection can cause inflammation, pain, discharge, or redness in the eye, but not necessarily vision loss or tissue necrosis. Bacterial infection can usually be treated with antibiotics, which can prevent or reverse the damage.
