A client is diagnosed with systemic lupus erythematosus (SLE). What symptom would the nurse expect to see?

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.

Choice A reason: Blanching is the term that the nurse documents for this finding, because it describes the temporary whitening of the skin when pressure is applied. Blanching indicates that the blood vessels in the skin are constricted or compressed, and that the blood flow is reduced or interrupted. Blanching can be a normal response to cold, stress, or pressure, or it can be a sign of a problem, such as ischemia, infection, or inflammation.

Choice B reason: Warmth is not the term that the nurse documents for this finding, because it describes the increased temperature of the skin, not the color change. Warmth indicates that the blood vessels in the skin are dilated or expanded, and that the blood flow is increased or enhanced. Warmth can be a normal response to heat, exercise, or emotion, or it can be a sign of a problem, such as infection, inflammation, or allergy.

Choice C reason: Redness is not the term that the nurse documents for this finding, because it describes the original color of the skin, not the color change. Redness indicates that the blood vessels in the skin are dilated or expanded, and that the blood flow is increased or enhanced, as explained above. Redness can be a normal response to heat, exercise, or emotion, or it can be a sign of a problem, such as infection, inflammation, or allergy.

Choice D reason: Nonblanching is not the term that the nurse documents for this finding, because it describes the opposite of what the nurse observed. Nonblanching means that the skin does not turn white when pressure is applied, but rather remains red or purple. Nonblanching indicates that the blood vessels in the skin are damaged or ruptured, and that the blood has leaked into the surrounding tissues. Nonblanching can be a sign of a serious problem, such as bruising, bleeding, or necrosis.
