The person with receptive aphasia would have lost which ability?

Safe performance of the Romberg test requires the nurse to stand nearby to prevent falls due to orthostatic instability. The patient is instructed to minimize base of support by placing the feet together. Observing the degree of swaying helps the clinician determine if the balance deficit is visual, vestibular, or proprioceptive in origin.

A. "Walk heel to toe across the room.": This instruction describes tandem gait testing, which evaluates cerebellar function and overall coordination during locomotion. While it tests balance, it is a dynamic assessment rather than the static postural assessment known as the Romberg test. It requires different neurological pathways for execution.

B. “Run the heel of foot down the opposite shin.": This maneuver is the heel-to-shin test, used primarily to assess appendicular coordination and cerebellar integrity. It is performed while the patient is supine or sitting. It checks for dysmetria rather than the static equilibrium measured by standing with eyes closed.

C. "Pronate and supinate the hands rapidly.": This instruction tests for dysdiadochokinesia, which is the inability to perform rapid alternating movements. It is a specific sign of cerebellar dysfunction. It does not involve standing balance or the integration of proprioceptive and visual cues required for the Romberg test.

D. "Stand with your feet together with eyes closed.": This is the standard procedural instruction for the Romberg test. It removes visual input, forcing the brain to rely on vestibular and proprioceptive signals to maintain an upright posture. This specific position allows the nurse to observe for pathological swaying or loss of balance.

The neurocranium consists of 8 bones that form the protective vault surrounding the brain. It is distinguished from the viscerocranium, which comprises the facial skeleton. These bones are joined by sutures, which are immobile fibrous joints, providing structural integrity to the skull.

A. Occipital: This bone forms the posterior and inferior base of the cranium and contains the foramen magnum. It articulates with the atlas of the vertebral column. It is a primary component of the cranial vault protecting the cerebellum.

B. Temporal: These paired bones form the lateral walls and base of the skull, housing the structures of the inner ear. They articulate with the mandible at the temporomandibular joint. They are essential components of the lateral neurocranium.

C. Frontal: This bone forms the forehead and the superior portion of the orbit and the anterior cranial fossa. It contains the frontal sinuses and provides protection for the frontal lobes. It is a major constituent of the cranium.

D. Parietal: These paired bones form the bulk of the superior and lateral vault of the skull. They meet at the sagittal suture and articulate with the frontal and occipital bones. They are fundamental parts of the cranial structure.

E. Zygomatic: Known as the cheekbones, these are components of the viscerocranium or facial skeleton rather than the neurocranium. They form the lateral wall and floor of the orbit. They do not contribute to the protective brain case.
