What aspect of the nursing process is demonstrated when administering insulin via a syringe?

Administering insulin via a syringe exemplifies the implementation phase of the nursing process. During this phase, nurses carry out the interventions and actions that have been planned for the patient's care. In this context, administering insulin is a direct application of a nursing intervention aimed at managing the patient's blood glucose levels.

Implementation involves putting into practice the strategies developed during the planning stage, ensuring that the care delivered aligns with the established goals and objectives for patient health. This action is critical because it directly affects the patient's immediate health status, emphasizing the importance of proper technique and adherence to protocols for medication administration.

Other phases, like assessment and evaluation, do not pertain to the act of administering medication itself; instead, they involve gathering data or determining the outcomes of interventions after they have been conducted. Planning relates to developing strategies for patient care but does not include the execution of those strategies. Therefore, the process of giving insulin aligns specifically with the implementation aspect of the nursing process.
