A nurse is teaching a group of nursing students about the use of memantine (Namenda) for Alzheimer's disease. Which statement by a student indicates understanding of the teaching?
a. "Memantine is indicated for patients with mild to moderate Alzheimer's disease."
b. "Memantine modulates the effects of glutamate to alter calcium influx into neurons."
c. "Memantine prevents calcium from leaving neurons, which improves their function."
d. "When used with donepezil, memantine increases the amount of calcium in neuronal cells."
ANS: B
Memantine modulates the effects of glutamate, which is involved in calcium influx into neuronal cells. Memantine is used for patients with moderate to severe AD. Memantine does not prevent calcium from leaving cells; it only affects the influx of calcium. Although the effects of memantine and donepezil appear to be synergistic, the result is not always an increase in the amount of calcium in the cells.
