Neuroscientific Basis and Practical Applications
CHAPTER 1: CHEMICAL NEUROTRANSMISSION
Question 1
A patient with depression mentions to the nurse, "My mother says depression is a
chemical disorder. What does she mean?" The nurse's response is based on the
theory that depression primarily involves which of the following
neurotransmitters?
A) Cortisol and GABA
B) COMT and glutamate
C) Monamine and glycine
1
,D) Serotonin and norepinephrine
Answer: D
Rationale: One possible cause of depression is thought to involve one or more
neurotransmitters. Serotonin and norepinephrine have been found to be important
in the regulation of depression. There is no research to support that the other
options play a significant role in the development of depression .
Question 2
A patient has experienced a stroke (cerebral vascular accident) that has resulted in
damage to the Broca area. Which evaluation does the nurse conduct to reinforce
this diagnosis?
A) Observing the patient pick up a spoon
B) Asking the patient to recite the alphabet
C) Monitoring the patient's blood pressure
D) Comparing the patient's grip strength in both hands
Answer: B
Rationale: Accidents or strokes that damage Broca's area may result in the inability
to speak (i.e., motor aphasia). Asking the patient to recite the alphabet tests speech
production, which is controlled by Broca's area. Fine motor skills, blood pressure
control, and muscle strength are not controlled by the Broca area .

,Question 3
The patient diagnosed with schizophrenia asks why psychotropic medications are
always prescribed by the doctor. The nurse's answer will be based on information
that the therapeutic action of psychotropic drugs is the result of their effect on:
A) The temporal lobe; especially Wernicke's area
B) Dendrites and their ability to transmit electrical impulses
C) The regulation of neurotransmitters, especially dopamine
D) The peripheral nervous system sensitivity to the psychotropic medications
Answer: C
Rationale: Medications used to treat psychiatric disorders operate in and around the
synaptic cleft and have action at the neurotransmitter level, especially in the case
of schizophrenia, on dopamine. The Wernicke's area, dendrite function, or the
sensitivity of the peripheral nervous system are not relevant to either schizophrenia
or psychotropic medications .
Question 4
An action potential is best described as:
A) A chemical signal that travels across the synapse
B) An electrical signal that travels down the axon
C) The release of neurotransmitters from the postsynaptic neuron
D) The binding of a ligand to a receptor
3
, Answer: B
Rationale: An action potential is a wave of depolarization that travels down the
axon to the axon terminal, where it triggers neurotransmitter release. It is electrical,
not chemical, in nature .
Question 5
What role do dendrites play in neuronal communication?
A) They release neurotransmitters
B) They synthesize neurotransmitters
C) They receive signals from other neurons
D) They insulate the axon
Answer: C
Rationale: Dendrites are the branched projections of a neuron that receive
incoming signals from other neurons via synapses. The axon transmits signals, and
dendrites are the primary receiving structures .
Question 6
The synaptic cleft is:
A) The space between the presynaptic and postsynaptic neurons
B) The site of neurotransmitter synthesis
