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

A. Administering pain medication: Administering medication typically requires a healthcare provider's order. Nurses can administer medications, but this action is not independent; it relies on a prescription.

B. Teaching a patient how to change their dressing before they are discharged: This is an independent nursing action. Nurses are educated and trained to provide patient education. Teaching patients about wound care and dressing changes falls under their scope of practice and doesn't require a physician's order.

C. Changing a patient's diet from pureed to regular: Changing a patient's diet usually involves dietary guidelines set by a healthcare provider. Nurses can implement these dietary changes based on the provider's orders but cannot independently change a patient's diet without an order from a healthcare provider.

D. Giving a back rub: Providing comfort measures like a back rub is an independent nursing action. It falls under the domain of holistic nursing care and doesn't require a specific physician's order. Nurses often use such measures to promote relaxation and alleviate discomfort.

E. Repositioning a patient in bed: This is an independent nursing action. Regular repositioning is crucial for preventing pressure ulcers and maintaining a patient's comfort. Nurses assess the patient's mobility and reposition them as needed without requiring specific orders each time.

A. "Refuses to have blood drawn. Doctor notified."
This option documents the patient's refusal but lacks specific information about the patient's reason for refusal, which is important for the care team to understand the context.

B. "Doctor notified of failure to draw ordered blood work."
This option focuses more on the failure to draw blood than on the patient's specific refusal and reasoning. It lacks information about the patient's perspective, which can be crucial for understanding their decision-making process.

C. "Blood not drawn because tests are no longer desired by the patient."
This choice provides a clear reason for not drawing blood (the patient's refusal) and includes the patient's perspective on the tests being 'useless.' However, it does not mention the action taken, such as informing the doctor, which is important for continuity of care.

D. "Refuses to have blood drawn; says tests are 'useless.' Doctor notified."
This option combines both the patient's refusal and their reason ('useless' tests) for refusing. Additionally, it includes the action taken, which is informing the doctor. This choice offers a comprehensive and informative description of the situation.
