Six months after her husband and children were killed in a car accident, a client is diagnosed with ulcerative colitis. The nurse would recognize that this situation validates which study perspective?

Correct Answer: B

Rationale: The correct answer is B: Psychoneuroimmunology. This perspective studies the interactions between psychological processes, the nervous system, and the immune system. The client's diagnosis of ulcerative colitis after a traumatic event like losing her family suggests a link between stress, emotions, and physical health. Ulcerative colitis is known to be influenced by stress and emotional factors, supporting the psychoneuroimmunology perspective. Choice A (Neuroendocrinology) focuses on the interactions between the nervous and endocrine systems, which may not fully explain the relationship between stress and the immune system in this case. Choice C (Diagnostic technology) is unrelated to the client's condition and situation. Choice D (Neurophysiology) primarily focuses on the study of the nervous system's structure and function, which does not address the psychological and immune system connections seen in this scenario.

Correct Answer: C

Rationale: Reaction formation is the correct defense mechanism in this scenario. The boy is displaying behavior opposite to his true feelings towards the girl to cope with his unconscious attraction or affection. This defense mechanism involves expressing the opposite of one's true feelings to manage inner conflicts. Displacement (A) involves redirecting emotions towards a less threatening target, projection (B) involves attributing one's own thoughts or feelings to someone else, and sublimation (D) involves channeling unacceptable impulses into socially acceptable behavior. These other options do not align with the behavior described in the question.

Correct Answer: B

Rationale: The correct answer is B: Biomedical technician. During laparoscopic surgery, a biomedical technician is crucial for maintaining and troubleshooting the specialized medical equipment used in the procedure, such as the laparoscope and other monitoring devices. They ensure that the technology functions properly, minimizing the risk of technical failures that could jeopardize the surgery. Other choices such as an information technician, electrician, and laboratory technician are not directly involved in the maintenance and operation of the specialized medical equipment used in laparoscopic surgery, making them incorrect options.

Correct Answer: D

Rationale: The correct answer is D: Medical records section. When needing a patient's medical record for research, the appropriate channel is the medical records section as they are responsible for maintaining and providing access to medical records. This ensures confidentiality and proper handling of sensitive information. Requesting permission through the doctor in charge (A) may not follow the proper protocol for accessing medical records. The hospital director (B) is not directly involved in handling medical records, and the nursing service (C) focuses on patient care rather than medical record retrieval. Therefore, D is the correct choice for obtaining permission to access a discharged patient's medical record for research purposes.

Correct Answer: A

Rationale: The correct answer is A because after administering a preoperative narcotic, the client may experience drowsiness and impaired coordination, increasing the risk of falls. Putting side rails up and instructing the client not to get out of bed helps prevent falls and ensures safety. Choice B is incorrect because sending the client to the operating room with family members does not address the safety concerns related to the effects of the narcotic. Choice C is incorrect because allowing the client to get up to go to the comfort room may lead to a higher risk of falls due to drowsiness and impaired coordination. Choice D is incorrect because obtaining consent form is not directly related to meeting the safety needs of the client after administering a preoperative narcotic.
