Correct Answer: A

Rationale: An increase in the neurotransmitter dopamine is associated with schizophrenia. Dopamine dysregulation is linked to some symptoms of schizophrenia, such as hallucinations and delusions. Depression (choice B) is more commonly associated with abnormalities in serotonin and norepinephrine. Alzheimer's disease (choice C) is primarily characterized by deficits in acetylcholine and other neurotransmitters. Anxiety disorders (choice D) are often linked to imbalances in neurotransmitters like serotonin, norepinephrine, and GABA, rather than dopamine.

Correct Answer: C

Rationale: To reduce the risk of venous thrombosis, the nurse should instruct the client to perform dorsiflexion and plantar flexion exercises regularly. These exercises help promote venous return and prevent venous thrombus formation. Options A, B, and D are beneficial in managing other complications of immobility, such as atelectasis and pressure ulcers, but they are less effective in preventing venous thrombosis compared to dorsiflexion and plantar flexion exercises.

Correct Answer: A

Rationale: Active listening is effectively demonstrated through attentive verbal and nonverbal communication strategies. To convey active listening and show the client that the nurse is engaged and attentive, it is essential for the nurse to sit facing the client. This posture communicates openness and willingness to listen. Option B, crossing arms and legs, creates a barrier and can signal defensiveness or disinterest, making it an incorrect choice. Option C, avoiding eye contact, hinders the establishment of a connection and can convey disengagement. Option D, leaning back in the chair, may give the impression of disinterest or lack of engagement. Therefore, maintaining eye contact and sitting facing the client are crucial nonverbal actions to exhibit active listening and promote effective therapeutic communication.

Correct Answer: B

Rationale: The correct answer is to assess the patient based on data collected from all sources. It is important for the nurse to gather information from various sources to form an objective assessment. Biased assessments by others should be evaluated as objectively as possible by the nurse, considering the potential impact of counter-transference. Documenting the other worker's assessment (Choice A) may be necessary for thorough documentation but should not influence the nurse's independent assessment. Validating the worker's impression by contacting the patient's significant other (Choice C) may not provide an accurate representation of the patient's condition. Discussing the worker's impression with the patient during the assessment interview (Choice D) can introduce bias and may not lead to an objective evaluation.

Correct Answer: B

Rationale: The client's statement about aliens coming to get them could indicate confusion, which raises concerns about their neurologic status. Since informed consent for surgery requires the client to be mentally competent, the nurse should assess the client's neurologic status to ensure they understand and can legally provide consent. Option A of making the client comfortable and letting them sleep does not address the potential neurologic issue. If the nurse finds the client to be confused, it is essential to inform the surgeon and seek permission from the next of kin if necessary. Therefore, assessing the client's neurologic status is the priority to ensure the client's ability to consent to the surgery.
