A patient asks, "What is the major difference between conventional health care and complementary and alternative medicine (CAM)?” The nurse’s best reply is that conventional health care

Correct Answer: A

Rationale: The correct answer is A because it highlights the key difference between conventional health care and CAM. Conventional health care focuses on treating the patient through medical interventions, procedures, and medications, while CAM emphasizes the interconnectedness of the body and mind and involves the patient actively in their healing process. This distinction underscores the patient's role in CAM therapies compared to the more passive role in traditional health care. Now, let's analyze why the other choices are incorrect: B: This choice is incorrect because it oversimplifies the differences between conventional health care and CAM by associating CAM solely with religious beliefs and high regulation, which is not universally true. C: This choice is incorrect as it generalizes conventional health care as being solely controlled by the health care industry and motivated by profit, which is not always the case, while oversimplifying CAM as the "people's medicine" not driven by profit. D: This choice is incorrect because it inaccurately portrays conventional health care as solely focused on health promotion and

Correct Answer: B

Rationale: The correct answer is B: Check active and inactive ingredients. This is important because some herbal preparations may contain ingredients that can interact with medications or cause adverse effects. By checking both active and inactive ingredients, the patient can ensure they are not allergic to any components. Incorrect choices: A: Buying from online sources is preferable and cheaper - Online sources may not provide reliable information on the quality and safety of herbal preparations. C: Discontinue use if side or adverse effects occur - While this may be necessary in some cases, it is not a proactive approach to ensuring safe use of herbal preparations. D: Avoid herbals during pregnancy and breast-feeding - While this is generally good advice, it is not applicable to all herbal preparations and may limit the patient's options without proper guidance.

Correct Answer: B

Rationale: The central sulcus separates the frontal lobe from the parietal lobe. This boundary is crucial for the organization of motor and sensory functions in the brain. The frontal lobe is responsible for higher cognitive functions and motor activities, while the parietal lobe processes sensory information such as touch and spatial awareness. Therefore, the central sulcus plays a key role in coordinating motor and sensory functions. Incorrect Choices: A: The temporal and occipital lobes are separated by the lateral sulcus, not the central sulcus. C: Complex motor activities are primarily controlled by the frontal lobe, not the central sulcus. D: Alertness to the environment is regulated by brainstem structures and the reticular activating system, not the central sulcus.

Correct Answer: A

Rationale: The correct answer is A: Amygdala. The amygdala is known to play a crucial role in processing emotions, including fear and anxiety. It is also involved in the perception and processing of odors. The amygdala helps in forming emotional memories and responses to various stimuli. Basal ganglia (B) is primarily involved in motor control, Prefrontal cortex (C) is associated with higher-order cognitive functions, and Wernicke's area (D) is responsible for language comprehension. Therefore, A is the correct choice as it is specifically linked to anxiety and odor perception.

Correct Answer: A

Rationale: The correct answer is A: Basal ganglia. The basal ganglia is involved in voluntary motor movements by helping to initiate and control movement. It plays a key role in regulating motor planning, coordination, and execution. The prefrontal cortex, choice B, is primarily responsible for higher cognitive functions such as decision-making and impulse control, not voluntary motor movements. The amygdala, choice C, is involved in emotional processing and memory, not motor movements. The limbic system, choice D, is a collection of brain structures involved in emotions, memory, and motivation, but not specifically in voluntary motor movements.
