Patient diagnosed with depression begins selective serotonin reuptake inhibitor (SSRI) antidepressant therapy. The nurse should provide information to the patient and family about which of the following?

Reasoning:

Choice A reason: Depression in older adults can cause "pseudodementia," where memory appears impaired. However, depression typically has a more rapid onset than dementia, and the cognitive deficits are usually related to a lack of effort or motivation rather than a permanent, progressive decline in cortical processing ability.

Choice B reason: Dementia is defined as a chronic, global, and usually irreversible decline in cognitive function. It progresses slowly over years, affecting memory, executive function, and language. This matches the description of a "gradual and progressive decline" in multiple domains of mental processing in the geriatric population.

Choice C reason: Medication toxicity usually presents with an acute onset of symptoms, often mimicking delirium. While it can cause confusion and impaired judgment, it is not a progressive or gradual decline; once the offending agent is removed or metabolized, the cognitive symptoms typically resolve rather than worsening.

Choice D reason: Delirium is characterized by an acute, abrupt onset and fluctuating levels of consciousness. It is usually caused by an underlying medical condition, such as an infection. Unlike dementia, delirium is a medical emergency that is potentially reversible and does not follow a slow, progressive course of decline.

Reasoning:

Choice A reason: Involuntary admission is specifically designed for situations where a patient lacks the capacity to consent or poses a danger to self or others. Mental health acts globally permit physicians to admit patients without consent if specific legal criteria regarding psychosis and safety are met via certification.

Choice B reason: Age does not strip an individual of their fundamental legal rights regarding mental health detention. In many jurisdictions, a 17-year-old is treated with similar due process rights as an adult, including the right to legal counsel and the right to challenge the legality of their psychiatric certification.

Choice C reason: Involuntary status does not equate to a loss of all legal rights. Patients retain the right to be informed of the reasons for their detention, the right to contact a lawyer, and the right to a judicial or administrative review of their clinical certification and status.

Choice D reason: All involuntary patients have the right to due process. This includes the right to apply to an independent review board or mental health tribunal. This body evaluates the clinical evidence to determine if the patient continues to meet the legal criteria for involuntary detention under the law.
