Asking the family if the patient has routines or preferences might help. Share strategies that work with the rest of the team. If it really is in the patient's best interest to have care they do not want (for example, if they need intravenous antibiotics, or are incontinent and need to be cleaned up), get it done as quickly and respectfully as is possible.
Make sure you are continually talking to the patient about what you are doing and why. Stay calm and engaged with the patient whilst delivering care.
