A nurse is assessing a toddler who has suspected lead poisoning. Which of the following findings should the nurse expect the client to manifest with acute lead poisoning?

A. Suppression: Suppression involves consciously pushing down or ignoring thoughts, feelings, or memories that are perceived as unacceptable or distressing. In this scenario, the client is not consciously trying to push down or ignore their behavior; instead, they are explaining their actions using a defense mechanism.

B. Reaction-formation: Reaction-formation occurs when an individual expresses feelings or behaviors that are the opposite of their true feelings or desires. In this case, the client's statement does not involve expressing the opposite of their true feelings. Instead, they are rationalizing their behavior.

C. Compensation: Compensation involves attempting to overcome feelings of inadequacy or failure in one area by excelling in another area. The client's statement does not suggest that they are compensating for anything; rather, they are explaining their behavior through a defense mechanism.

D. Rationalization: Rationalization involves providing logical or socially acceptable reasons for behavior that are not the true reasons. In this scenario, the client is rationalizing their behavior by attributing it to external factors, such as their boss's influence, rather than acknowledging their own responsibility for their actions. This defense mechanism allows the client to avoid facing the underlying issue of alcohol abuse by providing a seemingly reasonable explanation for their behavior.

A. Decreased auditory and visual acuity: Decreased auditory and visual acuity are not typically associated with primary dementia. While sensory impairments may occur with aging, they are not direct manifestations of dementia.

B. Decreased display of emotions: While individuals with dementia may experience changes in emotional expression, such as mood swings or emotional lability, a decreased display of emotions is not a universal manifestation. Some individuals may exhibit heightened emotional responses or become more emotionally labile as the disease progresses.

C. Forgetfulness gradually progressing to disorientation: This is the correct choice. Forgetfulness is often one of the initial signs of dementia, and it typically progresses to more severe cognitive impairments, including disorientation to time, place, and person. As dementia advances, individuals may become increasingly confused about their surroundings and lose track of time and events.

D. Personality traits that are opposite of original traits: While some changes in personality and behavior may occur in individuals with dementia, such as agitation, irritability, or apathy, personality traits that are opposite of the original traits are not necessarily characteristic of primary dementia. Personality changes in dementia are often more related to cognitive decline and impairment rather than a complete reversal of personality traits.
