A nurse is reinforcing teaching with the guardians of a 6-year-old child who has cystic fibrosis.

Which of the following information should the nurse include in the teaching?

Dementia is characterized by progressive memory impairment, including difficulty remembering recent events, names, and familiar faces. This memory loss can significantly impact the client's ability to perform daily tasks independently.

While dementia is typically a chronic and progressive condition, it is not uncommon for individuals with dementia to experience acute episodes of confusion, often referred to as "sundowning." These episodes tend to occur in the late afternoon or evening and can involve increased agitation, restlessness, and disorientation.

Illusions are perceptual distortions where a person misinterprets real sensory stimuli. In dementia, individuals may experience illusions, such as mistaking a coat hanging on a door for a person or misinterpreting shadows as threatening figures.

Catatonia, characterized by immobility and unresponsiveness, is not typically associated with dementia. It is more commonly seen in conditions such as schizophrenia or certain neurological disorders.

Fidelity, also known as loyalty or faithfulness, refers to the nurse's commitment to keeping promises and fulfilling their responsibilities to the client. By promising to walk with the client in the outdoor courtyard each day, the nurse is demonstrating fidelity by maintaining their commitment to the client's well-being and providing the support needed to alleviate anxiety.

Autonomy refers to the client's right to make decisions about their own care and treatment. While the nurse's promise supports the client's autonomy by accommodating their preference for exercising in the courtyard, it is not the principle being demonstrated by the nurse.

Justice refers to fairness and equality in healthcare, ensuring equitable treatment and distribution of resources. While justice is an important ethical principle, it is not directly applicable in this situation.

Nonmaleficence is the principle of doing no harm and taking actions to prevent harm to the client. While the nurse's promise of walking with the client aligns with the goal of reducing anxiety, it is not specifically related to preventing harm.
