Final answer:
The correct prioritization order is: Patient with a swollen, leaking cannula, Patient with low BSL, Patient with an anxious relative.
Step-by-step explanation:
The correct prioritization order is Patient with a swollen, leaking cannula, Patient with low BSL, Patient with an anxious relative.
This is because a swollen and leaking cannula indicates a potential risk of infection and needs immediate attention.
Low blood sugar level (BSL) can lead to complications such as dizziness, weakness, and confusion, so it should be addressed next.
Finally, while an anxious relative is important to consider, their needs can be addressed after attending to the patients with immediate physical concerns.
