Which of the following would the nurse most likely expect to find when assessing a client diagnosed with a frontal lobe contusion (in the Broca's Area) following a motor vehicle accident?
Blurred vision
Difficulty speaking
Loss of tactile sensation
inability to hear high-pitched sounds
The Correct Answer is B
A. Blurred vision is generally associated with visual system issues, which involve the occipital lobe or the visual pathways rather than the frontal lobe. Broca’s area, located in the frontal lobe, is involved in speech production and not in vision processing.
B. Difficulty speaking is a key symptom associated with damage to Broca’s area, which is located in the frontal lobe and responsible for speech production. A contusion in this area can lead to expressive aphasia, where the individual has trouble forming grammatically correct sentences and articulating words, while comprehension remains relatively intact.
C. Loss of tactile sensation would generally be associated with damage to the parietal lobe, where the primary somatosensory cortex is located. The parietal lobe processes sensory information such as touch, temperature, and pain. Since Broca’s area is located in the frontal lobe and primarily deals with language production, loss of tactile sensation is not typically expected from a frontal lobe contusion affecting Broca's area.
D. Inability to hear high-pitched sounds relates to issues with the auditory pathways or structures involved in hearing, such as the temporal lobe or the auditory cortex, not the frontal lobe. The frontal lobe and Broca’s area do not directly control auditory perception.

Correct Answer is B
Explanation
A. The soft palate should move during phonation. If it remains stationary, it could indicate a problem with cranial nerves IX and X. These nerves control the movement of the soft palate and the muscles involved in phonation.
B. This is the normal finding. During the assessment, when the patient says "ah," the uvula and soft palate should rise symmetrically. This movement indicates that cranial nerves IX and X are functioning properly. If the uvula and soft palate rise bilaterally, it means that both sides of the soft palate are being controlled correctly by these nerves.
C. Asymmetry in the soft palate could indicate dysfunction of cranial nerves IX and X. Normally, the soft palate should rise evenly on both sides when the patient says "ah." An asymmetrical soft palate suggests that one side is not functioning correctly, which may be due to nerve damage or weakness.
D. This is not a normal finding. If the uvula deviates to one side when the patient says "ah," it indicates a problem with the function of the cranial nerves. The deviation is usually towards the side opposite to the weak or affected side. This asymmetry in uvula movement can be due to a weakness or paralysis of the muscles on one side controlled by these nerves.
