The therapeutic action of neurotransmitter inhibitors that block reuptake cause:
a. decreased concentration of the blocked neurotransmitter in the central nervous system.
b. increased concentration of the blocked neurotransmitter in the synaptic gap.
c. destruction of receptor sites specific to the blocked neurotransmitter.
d. limbic system stimulation.
ANS: B
If the reuptake of a substance is inhibited, it accumulates in the synaptic gap, and its concentration increases, permitting ease of transmission of impulses across the synaptic gap. Normal transmission of impulses across synaptic gaps is consistent with normal rather than depressed mood. The other options are not associated with blocking neurotransmitter reuptake.

The nurse is preparing to administer methotrexate by mouth to a client with cancer. For what reasons would the nurse use the PO route rather than the other routes of administration?
Standard Text: Select all that apply. 1. The PO route is more acceptable to the client. 2. The PO route decreases the risk for phlebitis. 3. The PO route decreases the risk for tissue necrosis. 4. The PO route decreases the risk for nausea. 5. The PO route decreases the risk for vomiting.
