Final answer:
You should not use a vacuum cleaner to remove a pea from someone's ear. This method is dangerous and can cause serious damage. Proper removal should be conducted by a healthcare professional using safer tools like tweezers.
Step-by-step explanation:
When attempting to remove a pea from a person's ear, it is critical to avoid using any objects that could potentially push the pea further into the auditory canal, or worse, cause damage to the ear. Out of the options provided, a vacuum cleaner should definitely not be used. A vacuum cleaner is too powerful and uncontrollable for such a delicate procedure and can cause serious damage to the inner ear, including loss of hearing.
Safe removal typically involves using tools that allow for gentle extraction without applying pressure to the pea. Tweezers could be carefully used by medical professionals, but typically the removal should be done under the supervision of a healthcare provider to avoid any complications. In most cases, a person with a foreign object in the ear should seek medical attention rather than attempt removal themselves.
