"Normal" is an adjective in this sentence.

You correctly identified the verbs in the sentence: "alert," "oriented," and "is." Verbs are words that express actions, states, or occurrences. In this sentence, "alert" and "oriented" both function as past participle verbs, describing the state or condition of the patient. The verb "is" is the linking verb that connects the subject ("patient") with the adjective phrases ("alert and oriented" and "normal").
