Final answer:
All the mentioned actions, including reassessment, application of further care measures, and documentation, must be implemented after providing initial care. These steps are crucial for ensuring effective ongoing care, addressing new or persisting issues, and legally recording the process.
Step-by-step explanation:
After providing initial care, the actions that must be implemented include all of the above-mentioned options. You must reassess the patient and the effectiveness of your interventions to determine the next steps. If necessary, you should apply another appropriate care measure for the initial presenting problem or a new problem that may arise.
Lastly, it is crucial to document to establish a record of the events that took place, the care you provided, and the facts you discovered. This documentation process is not only essential for the continuity of care but also serves as a legal record.
