Final Answer:
The nurse is demonstrating the d. Interventions phase of the nursing process while teaching the patient how to administer insulin.
Step-by-step explanation:
The nursing process encompasses five essential phases: assessment, diagnosis, planning, implementation (or interventions), and evaluation. When the nurse educates the patient about administering insulin, it falls under the _implementation_ or _interventions_ phase of the nursing process. This phase involves executing the care plan by providing the necessary interventions or treatments identified during the planning phase to achieve the desired patient outcomes.
In this scenario, teaching the patient how to administer insulin involves putting the previously formulated plan into action. It is a proactive measure aimed at managing the patient's newly diagnosed diabetes mellitus. The nurse's role during the interventions phase is to carry out the planned strategies to meet the patient's healthcare needs effectively.
Administering insulin is a crucial aspect of managing diabetes mellitus. The nurse's demonstration and education help empower the patient to take an active role in their self-care and treatment regimen. This intervention aligns with the nursing process's interventions phase, focusing on implementing the plan of care to promote patient well-being and improve health outcomes. Thus, through education and guidance on insulin administration, the nurse fulfills the role of an active participant in the interventions phase of the nursing process.
