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 glu-tamate to alter calcium influx into neu-rons."
c. "Memantine prevents calcium from leav-ing neurons, which improves their func-tion."
d. "Memantine and donepezil combined may stop progression of Alzheimer's disease."
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. In studies, although the effects of memantine and donepezil appear to be synergistic or may confer independent benefits, they only demonstrate improvement in cognitive function and not a stop in disease progression.
