A person with anemia is prescribed erythropoietin subcutaneously. The nurse knows that erythropoietin:

The correct answer is choice A. Cataracts are a cloudy, opaque area over the lens of one eye that can impair vision

Choice B is wrong because diabetic retinopathy is a condition that affects the blood vessels of the retina, not the lens. It can cause blurred vision, floaters, or vision loss

Choice C is wrong because glaucoma is a condition that damages the optic nerve due to high pressure in the eye. It can cause blind spots, halos around lights, or vision loss

Choice D is wrong because macular degeneration is a condition that damages the macula, the central part of the retina. It can cause blurred or no vision in the center of the visual field

his intervention can help prevent pressure ulcers by reducing the amount of pressure on bony prominences and promoting blood circulation to the skin.

Choice A is wrong because placing the patient in a side-lying position only can increase the risk of skin breakdown by limiting the patient’s mobility and exposing the same areas to pressure. The patient should be repositioned frequently and encouraged to change positions if able.

Choice B is wrong because massaging bony prominences can cause tissue damage and increase the risk of skin breakdown by impairing blood flow to the area. Massaging should be avoided over bony prominences and areas of redness.

Choice D is wrong because keeping the head of the bed elevated higher than 30 degrees can cause shearing forces on the skin, which can lead to skin breakdown. The head of the bed should be kept at the lowest degree of elevation possible.

Choice E is wrong because inspecting skin every shift is not enough for a patient at risk for impaired skin integrity. The skin should be inspected at least every 2 hours or more frequently depending on the patient’s condition. Early detection of skin changes can help prevent further damage and promote healing.

Normal ranges for skin integrity are:

• Skin color: consistent with ethnicity and genetic background, no pallor, cyanosis, or jaundice.

• Skin moisture: dry to touch, no excessive perspiration or dryness. • Skin texture: smooth, soft, intact, with even surface.

• Skin temperature: warm to touch, no hyperthermia or hypothermia. • Skin turgor: elastic, returns to original shape after being pinched. • Skin integrity: no lesions, wounds, abrasions, or ulcers.
