The nurse giving a patient a back massage is performing an intervention considered to be:

A. Changing a surgical dressing: This is an example of a nursing implementation. Nurses frequently change dressings as part of their patient care responsibilities.

B. Return demonstration by the patient: This is also an example of a nursing implementation. Nurses often educate patients and then assess their understanding through return demonstrations to ensure the patient can perform tasks correctly at home.

C. Changing an ostomy bag: This is another example of a nursing implementation. It involves hands-on care for patients with ostomies, a responsibility often carried out by nurses.

D. Planning patient outcomes: While planning patient outcomes is crucial for nursing care, it falls more under the category of nursing interventions and nursing process rather than direct implementations.

E. Analyzing assessment data: Analyzing assessment data is part of the nursing process and helps in making decisions about nursing care. While it's essential, it's not a direct implementation action.

A. Patient leaving against medical advice:
When a patient decides to leave the hospital against medical advice, it's crucial to communicate this decision effectively. However, this situation does not specifically require a structured communication tool like SBAR. Rather, it necessitates clear communication to ensure the patient understands the risks and implications of leaving against medical advice.

B. Patient transfer to another facility:
During a patient transfer, especially between different healthcare facilities, it's essential to provide a comprehensive hand-off communication. SBAR is commonly used in such situations.

Situation: Describes the current situation and why the patient is being transferred.
Background: Provides relevant medical history and context.
Assessment: Presents the patient's current condition and vital signs.
Recommendation: Specifies what care and interventions the receiving facility should provide.
Using SBAR in this context ensures that all critical information is passed on accurately, minimizing the risk of errors and improving the continuity of care.

C. Visitor fall:
While a fall involving a visitor is an important incident, it doesn't typically require a structured communication tool like SBAR. Instead, it necessitates immediate response, assessment, and appropriate reporting within the hospital’s incident reporting system.

D. Needle stick injury to a nurse:
In the case of a needle stick injury, prompt reporting and proper follow-up are vital. While communication is crucial, it doesn't usually follow the structured format of SBAR. The nurse needs to report the incident to their supervisor or employee health, which would initiate appropriate protocols for testing, treatment, and documentation. Clear communication is necessary, but it doesn’t typically involve the use of the SBAR tool.
