Medical Surgical CNS vs PNS #4

Question

The nurse is caring for a client with a head injury. The client exhibits difficulty forming sentences and his wife mentions there has been a vast change in his personality. The nurse attributes this to damage to which part of the client’s brain?

Answers

  1. Frontal lobe
    • Rationale:

      This answer is correct because damage to the frontal lobe causes speech difficulties, as well as changes in behavior. The frontal lobe controls motor functioning and problem solving, from the premotor cortex. Speech production is controlled by Broca’s area specifically.

  2. Parietal lobe
    • Rationale:

      This answer is not correct because the parietal area is in charge of touch perception, body orientation and sensory discrimination. This is also called the somatosensory cortex.

  3. Occipital lobe
    • Rationale:

      This answer is not correct because the occipital lobe is the visual cortex of the brain. It is responsible for sight, visual reception and interpretation.

  4. Temporal lobe
    • Rationale:

      This answer is not correct because the parietal lobe controls auditory processing and memory retrieval. The Werneick’s area of the temporal part of the brain is responsible for language comprehension.

Overview

The frontal lobe is responsible for motor control, problem solving and speech production. Emotions and behavior is also regulated by the frontal lobe.

Explanation

Learning Outcomes

The frontal lobe of the brain is responsible for motor control, problem solving and speech production. Emotions and behavior is also regulated by the frontal lobe. The frontal lobe controls motor functioning and problem solving from the premotor cortex. Speech production is controlled by Broca’s area specifically. Behavior changes are due to lack of impulsivity that the frontal lobe regulates. This leads to difficulty with self control. Emotion regulation from lack of self control, such as being unable to control anger or aggression can occur.

Test Taking Tip

Know the lobes of the brain and their function.
