The nurse is caring for a client who suffered a stroke 3 days ago and is assessing the client's state of arousal.
The nurse knows that the part of the body responsible for a person being alert or aroused is the
adrenal glands.
renin-angiotensin-aldosterone system.
cranial nerves.
reticular activating system.
The Correct Answer is D
Choice A rationale
The adrenal glands primarily produce hormones that regulate metabolism, immune system, blood pressure, stress response, and other essential functions. While these hormones are crucial for overall bodily function and indirectly influence alertness and arousal, they are not the primary neurological structures responsible for maintaining a conscious and aroused state.
Choice B rationale
The renin-angiotensin-aldosterone system (RAAS) is a hormonal system that regulates blood pressure and fluid balance. While changes in blood pressure and fluid balance can affect overall well-being and indirectly influence alertness, the RAAS is not the neurological center responsible for a person's state of arousal.
Choice C rationale
Cranial nerves are a set of twelve paired nerves that emerge directly from the brain. They are responsible for a wide range of sensory and motor functions, including vision, hearing, taste, smell, facial movements, and swallowing. While some cranial nerves contribute to sensory input that can influence alertness, they are not the central structure responsible for maintaining arousal itself.
Choice D rationale
The reticular activating system (RAS) is a network of neurons located in the brainstem that plays a crucial role in regulating wakefulness, alertness, and the sleep-wake cycle. It filters incoming sensory information and relays important signals to the cerebral cortex, maintaining a state of arousal and consciousness. Damage to the RAS, such as that which can occur following a stroke, can lead to altered levels of consciousness. .

Correct Answer is D
Explanation
Choice A rationale
Dividing time evenly among patients reflects the professional value of justice, ensuring fair allocation of nursing resources based on patient needs rather than strict equality of time. Justice in nursing involves impartiality and equitable treatment.
Choice B rationale
Demonstrating care and concern for a patient's culture and beliefs aligns with the professional value of respect for autonomy and human dignity. It involves acknowledging and valuing the patient's individuality and their right to self-determination in healthcare decisions.
Choice C rationale
Encouraging the patient to make decisions about food selection promotes patient autonomy, allowing them to exercise their right to make choices about their care. This respects their preferences and empowers them in their healthcare journey.
Choice D rationale
Performing patient assessment and recording findings accurately exemplifies integrity, which involves honesty, truthfulness, and adherence to ethical principles. Accurate documentation provides an honest representation of the patient's condition and the care provided, crucial for safe and effective nursing practice.
Correct Answer is D
Explanation
Choice A rationale
A physician's license is primarily concerned with their medical practice, diagnosis, and treatment of patients. While medication security is important in patient care, the direct responsibility for the secure storage and accurate documentation of narcotics in a facility, according to its policies, falls on the nursing staff. Disciplinary actions related to these specific failures would typically target those directly involved in the lapse of protocol.
Choice B rationale
A pharmacist's license governs the dispensing and management of medications within a pharmacy setting. While pharmacists play a crucial role in the supply chain and providing information about medications, the day-to-day secure storage and inventory control of narcotics within a long-term care facility, as per the facility's policies, is the responsibility of the nurses on duty.
Choice C rationale
A facility's license pertains to the operational standards and overall compliance of the healthcare institution. While the failure to secure narcotics and maintain proper documentation could potentially lead to issues with the facility's licensing if it reflects systemic problems, the initial disciplinary actions for direct violations of nursing policies regarding medication handling would likely target the individual nurses involved.
Choice D rationale
Nurses are directly responsible for adhering to the policies and procedures of the healthcare facility regarding the handling and documentation of medications, especially controlled substances like narcotics. Failing to keep narcotics in a locked, secure location and neglecting to document counts before and after each shift are direct violations of these professional responsibilities and institutional guidelines, potentially leading to disciplinary actions against their nursing licenses.
