The correct answer highlights that visual impairment can occur as a symptom of hyperventilation. Hyperventilation leads to an imbalance of oxygen and carbon dioxide in the bloodstream. When a person hyperventilates, they expel too much carbon dioxide, which can result in a condition known as respiratory alkalosis. This condition may cause various neurological symptoms, including visual disturbances, since the brain requires a balanced level of carbon dioxide for optimal functioning.

Understanding the physiological responses to hyperventilation is essential for identifying all potential symptoms. While increased heart rate is a common response to stressors or anxiety, it is not the most direct correlation to hyperventilation itself. Heightened sense of smell and nausea are not typical symptoms directly related to hyperventilation; instead, they can be associated with other medical conditions or situational responses but are not specifically indicative of breathing changes.
