A patient asks, "What are neurotransmitters? The doctor said mine are imbalanced." Select the nurse's best response
a. "How do you feel about having imbalanced neurotransmitters?"
b. "Neurotransmitters protect us from harmful effects of free radicals."
c. "Neurotransmitters are substances we consume that influence memory and mood."
d. "Neurotransmitters are natural chemicals that pass messages between brain cells."
ANS: D
The patient asked for information, and the correct response is most accurate. Neurotransmitters are chemical substances that function as messengers in the central nervous system. They are released from the axon terminal, diffuse across the synapse, and attach to specialized receptors on the postsynaptic neuron. The distracters either do not answer the patient's question or provide untrue, misleading information.
