What is the main reason for gathering supplies before administering medication?

Gathering supplies before administering medication primarily serves to reduce the chance of interruption during the administration process. This is crucial because disruptions can lead to mistakes, such as incorrect dosages or missed medications. By preparing all necessary supplies in advance, the caregiver can create a more controlled and focused environment, making it easier to follow the proper procedures and ensure the safety of the patient.

In addition, having everything ready minimizes the need to leave the patient unattended, which not only enhances the efficiency of care but also helps in maintaining the patient's comfort and security during the procedure. Ensuring that all equipment and medications are ready before starting also reflects a commitment to thoroughness and professionalism in medication administration.

The other options are not aligned with best practices in medication administration. Ensuring a surplus of supplies does not directly contribute to patient safety or care quality. Creating distractions for the patient is counterproductive and can lead to anxiety or confusion. Lastly, aiming to impress the nursing staff does not directly impact the effectiveness or safety of the medication administration process.
