An elderly female client on the mental unit suddenly becomes upset because she can't remember where she is and she says, 'I can't think straight.' The staff has never witnessed this behavior in the client, and this type of complaint is not documented in the nursing history. What is the client most likely experiencing?

Correct Answer: D

Rationale: The correct answer is D: Delirium. Delirium is characterized by sudden onset confusion, disorientation, and impaired cognitive function. In this scenario, the elderly client's sudden confusion and inability to think straight suggest an acute change in mental status, which is indicative of delirium. Delirium is often triggered by underlying medical conditions or medications. A: Hallucinations involve perceiving things that are not real, which is not described in the scenario. B: Dementia is a chronic condition with gradual cognitive decline, not sudden onset confusion. C: Delusions are fixed false beliefs, which are not mentioned in the scenario. In summary, the client is most likely experiencing delirium due to the sudden onset of confusion and cognitive impairment, which is not consistent with hallucinations, dementia, or delusions.

Correct Answer: C

Rationale: The correct answer is C because disturbed thought processes indicate cognitive impairment. Thus, the expected outcome should focus on improving cognitive functioning to achieve optimal mental clarity and decision-making. Safety (A) is important but not directly related to cognitive improvement. Meeting basic needs (B) and maintaining relationships (D) are important but not the primary focus when the diagnosis is disturbed thought processes. So, the priority is on enhancing cognitive functioning to address the root cause of the issue.

Correct Answer: A

Rationale: The correct answer is A: Allow the patient to talk at a comfortable pace. This intervention is appropriate because it promotes the patient's autonomy and empowerment in sharing their experience, which can be therapeutic. It also helps establish trust and rapport, facilitating effective communication and assessment. Incorrect choices: B: Placing the patient in a private room with a caregiver can be important for privacy and support but may not be the immediate priority. C: Posing questions in nonjudgmental, empathetic ways is crucial but may not be as important as allowing the patient to talk at their own pace initially. D: None of the above is incorrect as allowing the patient to talk is a crucial step in providing appropriate care for a patient who has experienced trauma.

Correct Answer: C

Rationale: The correct answer is C because both statements A and B provide valid reasons supported by psychological principles. Statement A is correct as the presence of a loved one can indeed provide comfort and support, reducing anxiety and potentially improving test outcomes. Statement B is also accurate as testing in familiar surroundings can help the client feel safe and secure, leading to more reliable results. Therefore, combining these two factors - the presence of a loved one and testing in a comfortable environment - would likely yield the most reliable results by addressing both emotional and environmental factors impacting the client's anxiety levels during the test.

Correct Answer: A

Rationale: The correct answer is A because a quiet, well-lit room without glare or shadows helps reduce environmental stimuli that can exacerbate delirium and altered perceptions. This environment promotes calmness and clarity for the patient. Choice B is incorrect as it may increase distractions and stimuli. Choice C may lead to inadequate lighting that can worsen confusion. Choice D is incorrect as environmental modifications are crucial for managing delirium.
