1. A patient with depression mentions to the nurse, My mother says depression is a ch

depression primarily involves which of the following neurotransmitters?

a. Cortisol and GABA h h

3. The patient diagnosed with schizophrenia asks why psychotropic medications are al

ways prescribed by the doctor. The nurses answer will be based on information thatthe
h h h h h h h h h h h h h h h
therapeutic action of psychotropic drugs is the result of their effect on:
h h h h h h h h h h h
a. The temporal lobe; especially Wernickes area
h h h h h
b. Dendrites and their ability to transmit electrical impulses

Research indicates that stress causes a release of corticotropin-

releasing factors that suppress the immune system. Studies indicate that psychiatric dis

nursing intervention? h
a. Expression of emotion h h
b. Detecting auditory stimuli h h
c. Receiving visual images h h
d. Processing associations h
ANS: D h
The parietal lobe is responsible for associating and processing sensory information that

allows for functions such as following directions on a map, reading a clock, dressing sel

f, keeping appointments, and distinguishing right from left. Emotional expression is ass

ght cerebral cortex. During assessment, the nurse would expect to find that the patient

:
a. Demonstrates major deficiencies in speech h h h h
b. Is unable to effectively hold a spoon in the left hand

c. Has difficulty explaining how to go about using the telephone
h h h h h h h h h
d. Cannot use his right hand to shave himself or comb his own hair h h h h h h h h h h h h
ANS: B h
The cerebral hemispheres are responsible for functions such as control of muscles. The
h h h h h h h h h h h h h
right hemisphere mainly controls the motor and sensory functions on the left sideof the

body. Damage to the right side would result in impaired function on the left side of the b

The right side of the bodys motor activity is controlled by the left cerebral cortex.

hances the g- h h
aminobutyric acid (GABA) system. Which patient behavior willprovide evidenc
h h h h h h h h h

h h h h h h
a. The patient is actively involved in playing cards with other patients.
h h h h h h h h h h
b. The patient reports that, I dont feel as anxious as I did a couple of days ago.

ANS: B h
GABA is the principle inhibitory neurotransmitter. The medication should provide ana

affected by g-aminobutyric acid. h h h
10. The patients family asks whether a diagnosis of Parkinsons disease creates ani

sess for such a comorbid condition?

a. Has your father exhibited any signs of depression? h h h h h h h
b. Does your father seem to experience mood swings?
