A nurse is teaching a client who has peripheral venous disease about management of symptoms. Which of the following client statements indicates to the nurse an understanding of the teaching?

Answer: C. "I am not worried. This sort of thing happens all the time to us 'old people.'"

A. "I brought an updated list of all the medications he takes at home to help you and the doctors determine what the cause of this could be."
This response indicates understanding and proactive involvement in the client’s care. An updated medication list is crucial in evaluating potential causes of delirium, as certain medications or interactions can contribute to changes in mental status.

B. "I notified our family members that they should not come visit for a while, until they are better."
This statement reflects an understanding of the need for a calm environment for the client experiencing delirium. Reducing stimuli and visitors can help the client focus on recovery. It indicates the spouse is aware of the potential impact of social interactions on the client’s condition.

C. "I am not worried. This sort of thing happens all the time to us 'old people.'"
This response indicates a need for further teaching. It reflects a possible misunderstanding of delirium as a normal part of aging, which can be dismissive of the seriousness of the condition. Delirium is often a sign of underlying medical issues and should be treated with concern and urgency. Clients and their families need to understand that delirium is not a typical or benign occurrence and requires appropriate evaluation and intervention.

D. "I am trying to stay positive. I know that most people return to normal, but it is hard to see them like this."
This statement indicates a hopeful attitude while acknowledging the difficulty of the situation. It shows understanding that recovery is possible and reflects the spouse's emotional processing of the situation. Maintaining a positive outlook can be beneficial for both the client and the family during recovery.

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.
