Final answer:
The nurse's action that demonstrates The Joint Commission's safety focus is assessing the client's respirations when administering opioids, which is crucial for preventing respiratory depression and ensuring patient safety.
Step-by-step explanation:
The action by the nurse that reflects The Joint Commission's main objective of safety in health care is B) Assessing the client's respirations when administering opioids. This action is directly related to patient safety, as opioids can depress respiratory function. It is important for health care providers to monitor patients closely for signs of respiratory distress and ensure that treatment is provided safely.
Actions such as performing range-of-motion exercises or ensuring proper nutrition are important for overall patient care but do not directly pertain to the immediate safety concerns associated with The Joint Commission's standards. Delegating a bath to a nursing assistant is part of general patient care and does not directly reflect The Joint Commission’s focus on safety processes such as ensuring strict patient monitoring or preventing medication errors.
Direct supervision by a registered nurse, especially in the context of providing treatments such as dialysis, exemplifies The Joint Commission's standards. During dialysis, a nurse must review patient history and current condition, assess and respond to patient needs, and monitor the dialysis process to ensure safety and the effectiveness of the treatment.
