C. Delirium

D. Tinnitus

The correct answer is C. Delirium.

Headache and dizziness(vertigo) are common symptoms of anemia.

Tinnitus is the perception of sounds that occurs in the absence of external acoustic stimulus. The pathomechanism of tinnitus is thought to be complicated and therefore remains debatable. Among several risk factors, such as increased age, female gender, and hearing loss, anemia is especially related to pulsatile tinnitus due to an altered hemodynamic status although the prevalence of pulsatile tinnitus in anemia patients has not been reported in previous studies. Anemia results in decreased oxygen carrying capacity of the blood, which carries an associated risk of insufficient oxygen delivery and cellular hypoxia. The compensatory increased flow state and turbulence are perceived as tinnitus in the ear, and the recognition of a hyperdynamic circulatory state as the cause of the tinnitus avoids unnecessary diagnostic tests and is essential in determining appropriate treatment.
