A family member tells the nurse that much information is available on the internet about medications. This family member asks the nurse to explain what neurotransmitters are impacted by lithium. Which nursing response is correct?
1. Lithium interacts with GABA and opens the chloride channels.
2. Lithium lowers the amount of serotonin and norepinephrine available in the neural synapses.
3. Lithium increases the amount of dopamine available at the postsynaptic receptor.
4. Lithium raises the norepinephrine levels in the neural synapse.
2
Rationale: Lithium aids in the reduction of neurotransmitter release, this results in lower amounts of serotonin and norepinephrine in the neural synapses. Lithium does not interact with GABA and open chloride channels, does not increase the amount of dopamine available at the postsynaptic receptor, and does not raise the norepinephrine levels in the neural synapse.
