A nurse is caring for a client who has been admitted to the mental health unit. While reinforcing teaching about the client's prescribed medications, the nurse communicates truthfully about the adverse effects of the medications. Which of the following ethical concepts is the nurse exhibiting?

a. Memory loss that disrupts ADLs

Explanation: Dementia is a condition characterized by a decline in cognitive function that affects a person's ability to perform activities of daily living (ADLs). Memory loss is a common symptom of dementia, particularly in the early stages. The memory loss can disrupt a person's ability to carry out tasks they were previously able to do independently, such as dressing, bathing, and eating. Therefore, option a is the correct answer.

Option b, catatonia, is a condition characterized by a lack of movement or activity, which is not typically associated with dementia.

Option c, illusions, involve a misinterpretation of sensory information and may occur in some forms of dementia but are not a defining feature.

Option d, pressured speech, is a symptom commonly associated with mania or bipolar disorder, but is not typically seen in dementia.

Radiation therapy can cause increased sensitivity and dryness in the skin. Exposing the neck to cold temperatures may exacerbate these symptoms and potentially lead to discomfort or skin damage. Encourage the client to keep the neck covered and warm, especially when going outside in cold weather.

While proper nutrition is important during radiation therapy, the specific instruction to eat three large meals each day is not necessarily applicable or beneficial. It is generally recommended to have a balanced and nutritious diet, which may include smaller, frequent meals or snacks if the client's appetite is affected.

During radiation therapy, the skin in the treatment area can become sensitive and prone to irritation. Rubbing the neck vigorously with a washcloth can further irritate the skin. Instead, advise the client to gently cleanse the neck using a mild, non-irritating soap and patting the skin dry with a soft towel.

While radiation therapy can cause certain side effects, such as dry mouth or difficulty swallowing, it is generally not necessary to restrict fluid intake unless specifically advised by the healthcare provider. Adequate hydration is important for overall health and well-being, and the client should be encouraged to drink enough fluids unless instructed otherwise.
