Final answer:
The speech area of the brain is located in both the frontal lobe (Broca's area for language production) and the temporal lobe (Wernicke's area for speech comprehension).
Step-by-step explanation:
The nurse correctly identifies the speech area of the brain as being located in the frontal lobe and the temporal lobe. Specifically, the Broca's area, important for language production, is found in the frontal lobe, while the Wernicke's area, which is essential for speech comprehension, is located within the temporal lobe.
The frontal lobe is situated at the front of the brain and is involved in reasoning, motor control, emotion, and language.
It contains the motor cortex for movement coordination and the prefrontal cortex for higher-level cognitive functioning.
On the other hand, the temporal lobe handles the processing and interpreting of sounds, and plays a role in memory and some aspects of language, including housing the auditory cortex and Wernicke's area.
