Final answer:
An EMT must prioritize their duty to respond to medical calls. If a partner is emotionally compromised, it's essential to request additional assistance to maintain the quality and safety of care.
Step-by-step explanation:
As an EMT, your duty to act and provide medical care to those in need is of the utmost priority. Seeing that your partner is in an emotional state and not able to perform to the best of their abilities, the appropriate action would be to respond to the call but also notify dispatch to send another unit to assist. Given that EMTs are often faced with split-second decisions, it is crucial to ensure that the care provided is not compromised by personal circumstances, ensuring both the safety of the patient and the EMTs involved.
