Final answer:
Both 'Dr. Carter' and 'the patient' are the nouns in the given sentence, with 'Dr. Carter' being a proper noun and 'the patient' a common noun. 'Harassed' functions as a verb, indicating the action in the sentence.
Step-by-step explanation:
In the sentence, "The patient harassed Dr. Carter.", both "Dr. Carter" and "the patient" are nouns. "Dr. Carter" is a proper noun because it's the specific name of a person, while "the patient" is a common noun as it refers to any person in the role of a patient. The word "harassed" is not a noun; it is a verb because it describes the action that the patient took. In English, it is important that a doctor shows that they care for their patients, and this is part of the ethical considerations in medicine. When referring to someone with an unknown gender or in a generic manner, plural pronouns like "they" have become increasingly accepted as inclusive language.
