What triggers the afferent pathways, resulting in the sensation of pain?
Spinal cord
Nociceptors
Endorphins
Cortex
The Correct Answer is B
Choice A rationale:
The spinal cord plays a crucial role in pain transmission, but it does not initiate the afferent pathways. It receives pain signals from nociceptors and relays them to the brain for processing.
The spinal cord is also involved in pain modulation, as it can dampen or amplify pain signals depending on various factors. However, it is not the primary trigger for pain sensation. That role belongs to nociceptors.
Choice B rationale:
Nociceptors are specialized sensory receptors that detect potentially damaging stimuli, such as intense heat, pressure, or chemical irritants.
They are located throughout the body, including the skin, muscles, joints, and internal organs.
When nociceptors are activated, they generate electrical signals that travel along nerve fibers to the spinal cord and brain. This process initiates the afferent pathways, which ultimately lead to the conscious perception of pain.
Nociceptors are essential for protecting the body from harm. They alert us to potential dangers and trigger responses that help us avoid injury or further damage.
Choice C rationale:
Endorphins are natural pain-relieving substances produced by the body. They act on receptors in the brain and spinal cord to reduce pain perception.
However, endorphins do not trigger the afferent pathways. They work by modulating pain signals that have already been initiated by nociceptors.
Choice D rationale:
The cortex is the outer layer of the brain that is responsible for higher-level functions, such as thinking, feeling, and decision- making.
It plays a role in the conscious experience of pain, but it does not trigger the afferent pathways.
The cortex receives pain signals from the spinal cord and processes them, leading to the awareness of pain.

Correct Answer is A
Explanation
Choice A rationale:
It is crucial for the nurse to prioritize patient safety and adhere to professional guidelines when encountering a potential diversion of controlled substances. Informing the charge nurse is the most appropriate initial action for several reasons:
Chain of Command: The charge nurse holds a supervisory position and is responsible for addressing issues within the unit, including concerns about medication diversion. Reporting suspicions to the charge nurse ensures adherence to the established chain of command and facilitates a prompt, organized response.
Confidentiality and Objectivity: The charge nurse is trained to handle sensitive situations discreetly and objectively. They can initiate a thorough investigation while maintaining confidentiality and protecting the rights of all involved parties.
Access to Resources: The charge nurse has access to resources and authority to take immediate action, such as securing medications, initiating patient assessments, and notifying appropriate personnel within the healthcare facility.
Collaboration and Support: The charge nurse can provide guidance and support to the reporting nurse, ensuring their concerns are addressed appropriately and that they feel safe in coming forward with their suspicions.
Rationale for other choices:
B. Reporting the incident directly to the hospital’s security department might be premature without first informing the charge nurse. The charge nurse can assess the situation, gather more information, and determine the most appropriate course of action, which may or may not involve security at this initial stage.
C. Requesting assistive personnel (AP) to monitor the other nurse’s actions is inappropriate. It places a burden on APs who are not trained or authorized to investigate such matters. It could also compromise the integrity of the investigation and potentially jeopardize patient safety.
D. Confronting the other nurse directly is not recommended. It could escalate the situation, create a hostile work environment, and potentially compromise the investigation. It is essential to follow established protocols and involve appropriate personnel to ensure a fair and thorough investigation.
Correct Answer is C
Explanation
Rationale for Choice A:
Refer Questions to the Nursing Supervisor:
While it's essential to involve the nursing supervisor in situations that require their expertise or authority, it's not always necessary for basic inquiries about a patient's presence on the unit.
Disadvantages of referring calls to the nursing supervisor in this scenario:
It could delay the dissemination of essential information to concerned colleagues.
It could increase the workload of the nursing supervisor, potentially diverting their attention from more critical tasks. It could create a perception of a lack of transparency or openness among staff members.
Rationale for Choice B:
Transfer calls directly to the patient’s room:
Transferring calls directly to a patient's room without their consent breaches their privacy and confidentiality. It could also place undue stress on the patient, especially if they are not prepared to receive calls or discuss their health status.
Disadvantages of transferring calls directly to the patient’s room:
It violates the patient's right to privacy and confidentiality. It could disrupt the patient's rest and recovery.
It could place the patient in an uncomfortable position of having to answer questions about their health when they may not feel ready to do so.
Rationale for Choice C:
Acknowledge that the person is a patient on the unit, but give no specific details about the patient’s condition:
This approach strikes a balance between protecting the patient's privacy and providing necessary information to concerned colleagues. It verifies the patient's presence on the unit without disclosing any sensitive details about their health, thus adhering to ethical and legal guidelines.
Advantages of acknowledging the patient’s presence without providing details:
Respects the patient's right to privacy and confidentiality. Aligns with ethical and legal principles of healthcare.
Provides basic information to concerned colleagues without compromising patient information. Helps to establish trust and transparency among staff members.
Rationale for Choice D:
Contact the patient’s provider:
Contacting the patient's provider for every inquiry about the patient's presence is not practical or efficient. It could overburden the provider and delay the relay of information to concerned colleagues.
