Which nursing action is part of the implementation step of the nursing process?

The implementation step of the nursing process involves carrying out the planned interventions to achieve the desired patient outcomes. In this context, the action of repositioning a bed-bound patient every two hours is a direct nursing intervention aimed at preventing pressure ulcers and promoting patient comfort. This task is an active measure that the nurse takes based on the established care plan.

In contrast, assessing a patient for nutritional status falls under the assessment phase, where the nurse collects data to understand the patient's condition. Forming a nursing diagnosis is part of the diagnosis phase, as it involves analyzing the assessment information to identify the patient's problems. Checking the client's insurance coverage is not a clinical nursing action and does not relate directly to patient care, positioning it outside the nursing process. Therefore, repositioning the patient exemplifies an action taken during the implementation phase, making it the correct choice.
