A nurse is reviewing laboratory results for a client who has pericarditis. Which of the following blood test results should the nurse anticipate? (Select All that Apply.)

A. "Vision changes occur when blood vessels leak fluid or blood under a portion of the retina": This statement describes a symptom of diabetic retinopathy, not open-angle glaucoma. In open-angle glaucoma, vision changes primarily result from increased intraocular pressure (IOP) due to impaired drainage of aqueous humor, not leakage of fluid or blood under the retina.

B. "Vision changes occur when the cloudy lens alters the passage of light through the eye": This statement describes a symptom of cataracts, not open-angle glaucoma. Cataracts involve clouding of the lens inside the eye, which affects the passage of light and leads to visual disturbances. Open-angle glaucoma, however, primarily affects the optic nerve and visual field due to increased intraocular pressure.

C. "Vision changes occur when retinal tissue pulls away from the blood vessels in the eye": This statement describes a symptom of retinal detachment, not open-angle glaucoma. Retinal detachment occurs when the retina detaches from the underlying layers of the eye, leading to vision changes and potentially vision loss. Open-angle glaucoma, on the other hand, primarily involves increased intraocular pressure and optic nerve damage.

D. "Vision changes occur when pressure in the eye is increased due to a decrease of aqueous humor": This statement is accurate. In open-angle glaucoma, vision changes occur due to increased intraocular pressure resulting from inadequate drainage of aqueous humor from the eye. This increased pressure can lead to damage of the optic nerve, resulting in peripheral vision loss and potentially blindness if left untreated.

A. Encouraging increased mobility: While mobility is important for overall health, it may not be the primary lifestyle modification emphasized in the discharge teaching for heart failure. The focus is typically on dietary and fluid restrictions, medication adherence, and symptom management.

B. Dietary and fluid restrictions: Dietary and fluid restrictions are essential lifestyle modifications for managing heart failure. Clients are often advised to follow a low-sodium diet and restrict fluid intake to prevent fluid retention and exacerbation of heart failure symptoms.

C. Cessation of intravenous (IV) drug use: While cessation of intravenous drug use is important for overall health and may be addressed if relevant to the client's situation, it may not be a primary focus of discharge teaching specifically related to heart failure.

D. Cessation of hormonal supplements: Cessation of hormonal supplements may be recommended if they contribute to heart failure or exacerbate its symptoms. However, this recommendation would be specific to individual client circumstances and may not apply to all clients with heart failure.
