A nurse is providing care to a client who has spent several weeks in the intensive care unit because of complications related to shock. What adverse psychological outcomes should the nurse educate the client about prior to transfer to the medical unit?

A. "Your heart condition is caused by excessive stretching of the ventricles": Dilated cardiomyopathy (DCM) is characterized by the dilation or enlargement of the heart's chambers, particularly the ventricles. This dilation results in weakened myocardial contraction and impaired systolic function. The primary cause of DCM is often idiopathic (unknown), but it can also be secondary to various factors such as genetics, infections, toxins, or systemic diseases. The statement correctly identifies the pathophysiological basis of DCM as excessive stretching or dilation of the ventricles, leading to impaired cardiac function.

B. "Your heart condition is caused when the ventricular tissue becomes fibrous and fatty": This statement is incorrect. Fibrous and fatty changes in ventricular tissue are characteristic of another type of cardiomyopathy known as hypertrophic cardiomyopathy (HCM), not dilated cardiomyopathy (DCM). In DCM, the primary abnormality is dilation of the heart chambers rather than fibrous and fatty changes in the myocardium.

C. "Your heart condition is caused from stiffening of the walls of the ventricles": This statement describes restrictive cardiomyopathy (RCM), not dilated cardiomyopathy (DCM). In restrictive cardiomyopathy, the ventricular walls become stiff and rigid, impairing diastolic filling and ventricular relaxation. However, in DCM, the primary abnormality is dilation or enlargement of the ventricles rather than stiffening of the ventricular walls.

D. "Your heart condition is caused by thickening of the ventricular walls and septum": This statement describes hypertrophic cardiomyopathy (HCM), not dilated cardiomyopathy (DCM). In HCM, there is abnormal thickening of the ventricular walls and septum, leading to reduced chamber size and impaired diastolic filling. However, in DCM, the primary abnormality is dilation or enlargement of the ventricles rather than thickening of the ventricular walls.

A. "Vision changes occur when the retina begins to breakdown and collect bits of debris": This statement does not accurately describe the changes that occur in the eye during retinal detachment. Vision changes in retinal detachment primarily occur due to the separation of the retina from its underlying tissue layers, rather than the breakdown and collection of debris within the retina.

B. "Vision changes occur when retinal tissue pulls away from the blood vessels in the eye": Retinal detachment occurs when the retina, which is the light-sensitive layer at the back of the eye, pulls away from its normal position along the inner wall of the eye. This separation disrupts the blood supply to the retina, leading to vision changes. The most common symptom of retinal detachment is the sudden appearance of floaters or flashes of light in the visual field, followed by a shadow or curtain effect as the detachment progresses. Therefore, this statement accurately describes the pathophysiological mechanism underlying vision changes in retinal detachment.

C. "Vision changes occur when the cloudy lens alters the passage of light through the eye": This statement describes changes associated with cataracts, not retinal detachment. Cataracts involve clouding of the lens inside the eye, which can lead to vision changes such as blurriness or decreased visual acuity. However, cataracts are distinct from retinal detachment, which involves the separation of the retina from the inner wall of the eye.

D. "Vision changes occur suddenly due to complete obstruction of aqueous humor outflow": This statement describes the pathophysiology of acute angle-closure glaucoma, not retinal detachment. Acute angle-closure glaucoma is characterized by sudden elevation of intraocular pressure due to complete obstruction of the outflow of aqueous humor, leading to rapid onset of symptoms such as severe eye pain, blurred vision, and halos around lights. Retinal detachment, on the other hand, is characterized by the separation of the retina from its normal position, resulting in distinct vision changes such as floaters, flashes of light, and visual field defects.
