The nurse places a coin in the patient's hand, the patient is with eyes closed. The ability to identify an object by feeling it is defined as:

A. The trigeminal nerve (CN V) is primarily responsible for sensation in the face and the motor control of the muscles used for chewing. It does not have a role in balance or equilibrium, so it would not be the focus when assessing balance issues.
B. The facial nerve (CN VII) controls the muscles of facial expression and provides taste sensation to the anterior two-thirds of the tongue. While it plays a significant role in facial movement and taste, it is not involved in balance or equilibrium.
C. The olfactory nerve (CN I) is responsible for the sense of smell. It does not have any role in balance or equilibrium. Balance issues are not related to the olfactory nerve, so this is not the appropriate focus for balance assessment.
D. The vestibulocochlear nerve (CN VIII) has two major components: the cochlear nerve, which is responsible for hearing, and the vestibular nerve, which is responsible for balance and equilibrium. The vestibular component of CN VIII is crucial for maintaining balance and spatial orientation. When a client reports spontaneous loss of balance, this nerve should be the focus of additional assessment.

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.
