A client asks the nurse, "What are neurotransmitters? My doctor says they are at the root of my
problem.". The best reply would be
a. "You must feel relieved to know that your problem has a physical basis.".
b. "It is a rather high-level concept to explain. Perhaps you should ask the doctor to
tell you more.".
c. "Neurotransmitters are substances we eat daily that influence the brain functions
of memory and mood.".
d. "Neurotransmitters are chemicals manufactured in the brain that are responsible
for passing messages between brain cells.".
ANS: D
Option D gives the most accurate information. Neurotransmitters are chemical substances that
function as neuromessengers. They are released from the axon terminal and diffuse across the
synapse and attach to specialized receptors on the postsynaptic neuron. Option A does not answer
the client's question. Option B does not answer the client's question and is somewhat demeaning.
Option C provides untrue, misleading information.
