The therapeutic action of neurotransmitter inhibitors that block ...

[CQXA]

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.

Question 2

The nurse should assess a patient taking a drug with anticholinergic properties for inhibited function of the:
 
  a. parasympathetic nervous system.
  b. sympathetic nervous system.
  c. reticular activating system.
  d. medulla oblongata.

Answer to Question 1

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.

Answer to Question 2

ANS: A
Acetylcholine is the neurotransmitter found in high concentration in the parasympathetic nervous system. When anticholinergic drugs inhibit acetylcholine action, blurred vision, dry mouth, constipation, and urinary retention commonly occur.
