That potentiates the action of gaba which finding

that
potentiates the action of GABA. Which finding would be expected? A.
Reduced anxiety B. Improved memory C. More organized
thinking D. Fewer sensoryperceptual alterations ANS:A Increased levels of
GABA reduce anxiety, thus any potentiation of GABA action should result
in anxiety reduction. Memory enhancement is associated with
acetylcholine and substance P. Thought disorganization is associated
with dopamine. GABA is not associated with sensoryperceptual
alterations. KEY:Cognitive Level: Application | Integrated Processes:

Pharmacological and Parenteral Therapies 6. On the basis of
current knowledge of neurotransmitter efects, a nurse could
anticipate that the treatment plan for a patient with memory
difficulties might include medications designed to: A. inhibit GABA. B.
increase dopamine at receptor sites. C. decrease dopamine
at receptor sites. D.preventdestruction of acetylcholine. ANS: D
Increased acetylcholine plays a role in learning and memory.
Preventing destruction of acetylcholine by acetylcholinesterase would result
in higher levels of acetylcholine, with the potential for
improved memory. GABA is known to afect anxiety level rather than
memory. Increased dopamine would cause symptoms associated with
schizophrenia or mania rather than improve memory. Decreasing
dopamine at receptor sites is associated with Parkinson’s disease
rather than improving memory. KEY: Cognitive Level: Comprehension|

7. A patient has disorganized thinking associated with schizophrenia.
A PET scan would most likely show dysfunction in which part
of the brain? A. Temporal lobe B. Cerebellum C. Brainstem D. Frontal
lobe ANS: D The frontal lobe is responsible for intellectual
functioning. The temporal lobe is responsible for the
sensation of hearing. The cerebellum regulates skeletal muscle
coordination and equilibrium. The brainstem regulates internal organs.

a patient taking a drug with anticholinergic properties for
inhibited function of the: A. parasympathetic nervoussystem. B.
sympathetic nervoussystem. C. reticular activating system. D.
medulla oblongata. ANS:A Acetylcholine is the neurotransmitter found
in high concentration in the parasympathetic nervoussystem. When
acetylcholine action is inhibited by anticholinergic drugs,
parasympathetic symptoms such as blurred vision, dry mouth,
constipation, and urinary retention appear. The functions of the
sympathetic nervoussystem, the reticular activating system, and the
medulla oblongata are not afected by anticholinergics. KEY:
