A client asks the nurse to explain what metabolic syndrome is. Which of the following will the nurse include in education about risk factors for this syndrome? (Select all that apply.)

Choice A Reason: Edema is not a specific finding of a systemic infection, but rather a possible sign of fluid overload or impaired venous return. It can occur due to excessive infusion rate, heart failure, or obstruction of blood flow in or around the central line.

Choice B Reason: This is a correct choice. Purulent drainage at intravenous insertion site is a finding of a local infection that can spread systemically. It indicates bacterial invasion and inflammation of the skin and subcutaneous tissue around the catheter.

Choice C Reason: Redness at insertion site is a finding of a local infection that can spread systemically. It indicates increased blood flow and inflammation of the skin and subcutaneous tissue around the catheter.

Choice D Reason: Nausea is not a specific finding of a systemic infection, but rather a possible side effect of parenteral nutrition or a symptom of another condition. It can occur due to electrolyte imbalance, hyperglycemia, or gastrointestinal disorders.

Choice E Reason: This is a correct choice. Leukocytosis is a finding of a systemic infection that indicates increased production and release of white blood cells in response to infection. It can be detected by a blood test.

Choice F Reason: This is a correct choice. Fever is a finding of a systemic infection that indicates increased body temperature due to activation of the immune system and release of pyrogens. It can be measured by a thermometer.

Choice A reason: This is incorrect because loss of peripheral vision is not a manifestation of cataracts, but of glaucoma. Glaucoma is a condition that causes increased pressure inside the eye and damage to the optic nerve, which can lead to loss of vision in the outer edges of the visual field. The nurse should assess the client's intraocular pressure and visual field test results to rule out glaucoma.
Choice B reason: This is correct because a decreased ability to perceive colors is a manifestation of cataracts. Cataracts are a condition that causes clouding or opacity of the lens, which is the transparent structure behind the pupil that focuses light onto the retina. Cataracts can reduce the clarity and contrast of vision and make colors appear faded or yellowish. The nurse should ask the client about any changes in color perception or brightness of objects.
Choice C reason: This is incorrect because loss of central vision is not a manifestation of cataracts but of macular degeneration. Macular degeneration is a condition that affects the macula, which is the central part of the retina that is responsible for sharp and detailed vision. Macular degeneration can cause blurred or distorted central vision, difficulty reading or recognizing faces, or dark spots in the visual field. The nurse should assess the client's visual acuity and fundoscopic examination results to rule out macular degeneration.
Choice D reason: This is incorrect because seeing bright flashes of light and floaters is not a manifestation of cataracts but of retinal detachment. Retinal detachment is a condition that occurs when the retina, which is the layer of tissue at the back of the eye that converts light into nerve impulses, separates from its underlying support tissue. Retinal detachment can cause sudden flashes of light, floaters, or shadows in the visual field. The nurse should refer the client to an ophthalmologist immediately if retinal detachment is suspected.
