Correct Answer is B
Explanation
A. An occurrence report, also known as an incident report, documents the details of any unexpected event that occurs during the client's care. This includes falls. It is important to document the incident accurately and promptly in the client's medical record to ensure that all relevant information is recorded. However, this should not take priority over timely escalation of the issue.
B. It is essential to notify the client's healthcare provider (such as the physician or nurse practitioner) about the fall incident. The provider needs to be informed about the client's condition after the fall, any injuries sustained, and any immediate actions taken.
C. The nurse who witnessed or discovered the fall incident is responsible for completing the occurrence report. It should be filled out by the nurse who directly assessed the client's condition after the fall, documented any injuries, and initiated appropriate interventions. Asking another nurse to complete the report may not accurately reflect the details and actions taken by the nurse who was directly involved.
D. Risk management may need to be informed about the fall incident, especially if it resulted in injury to the client. Risk management is responsible for assessing the circumstances surrounding the fall, identifying potential risks or contributing factors, and implementing strategies to prevent future incidents. However, contacting risk management is typically done after initial actions such as ensuring client safety, notifying the provider, and documenting the incident.
Correct Answer is B
Explanation
A. Episodes of confusion could indicate various issues, such as metabolic disturbances, disease progression affecting the central nervous system, or medication side effects. However, confusion alone would not typically lead to an increase in morphine dosage. Therefore, this is not a likely explanation for why the client needed more morphine for pain relief.
B. Tolerance occurs when the body adapts to the effects of a medication over time, requiring higher doses to achieve the same therapeutic effect. This is a common phenomenon with opioids like morphine when used long-term for pain management. If the client's pain relief diminished despite increasing the dose, tolerance to morphine could indeed be the reason why higher doses were needed.
C. Addiction is a psychological and physiological dependence on a substance characterized by compulsive drug-seeking behavior and use despite harmful consequences. Addiction is not typically the reason why a client with terminal cancer would require an increased dose of morphine for pain relief. In this context, the focus is on managing pain rather than addiction.
D. If the client has not been adhering to the prescribed dosing schedule or has missed doses, it could result in inadequate pain control. This might necessitate an increase in morphine dosage to achieve adequate pain relief. However, this scenario would require further assessment to confirm.
