MENTAL HEALTH NURSING EXAM #15 QUESTIONS AND ANSWERS
2024
What are the 4 neurotransmitters? - correct answer Dopamine, Norepinephrine,
Serotonin, Histamine
What does Dopamine do? - correct answer Decreases: Parkinson's Disease
Increases: Schizophrenia
Involved in fine motor movement
Involved in integration of emotions and thoughts.
Involved in decison making.
Stimulates hypothalamus to release hormones
What does Norepinephrine do? - correct answer Decreases: depresssion
Increases: Mainia, anxiety, schizophrenia
Level in brain affects mood.
Attention and arousal.
Stimulates symepthetic branch of autonomic nervous system for "flight or fight"
response to stress.
What does serotonin do? - correct answer Decreases: depression
Plays a roll in sleep regulation, hunger, mood states, pain perception.
Hormonal activity.
Plays a roll in aggression and sexual behavior.
What does histamine do? - correct answer Decreases: sedation, weight gain
Involved in alertness.
Involved in inflammatory response.
Stimulates gastric secretion.
What are the 2 amino acids? - correct answer GABA and Glutamate
What does GABA do? - correct answer Decreases: anxiety, schizophrenia, mania,
Huntington's disease.
Plays a role in inhibition, reduces aggression, excitation, and anxiety.
May play a roll in pain perception.
Has antivonvulsant and muscle relaxing properties.
May impair cognition and psychomotor functioning.
What does Glutamate do? - correct answer Decreases: psychosis
Increases: Improved cognitive performance and behavioral tasks.
Prolonged increased state can be neurotoxic.
-Excitatory
-AMPA plays a role in learning and memory
, Agonists - correct answer Mimic neurotransmitters, bind to receptors, stimulate
receptors.
Partial agonists - correct answer Same affect as agonist, but smaller scale.
Antagonists - correct answer Block neurotransmitters from binding to receptors.
SSRI Dugs - correct answer Selective Serotonin Reuptake Inhibitors:
Fluoxetine
Sertraline
Paroxetine
Citalopram
Escitalopram
Fluvoxamine
SSRI- what do they do? - correct answer Block the reuptake of serotonin, thereby
making maore of the neurotransmitter available in the synapse.
FIRST LINE DEFENSE FOR ANXIETY AND DEPRESSION
SSRI- side effects - correct answer Common: nausea, restlessness or jitteriness, sleep
disturbances, sexual dysfunction.
CAN SEND BIPOLAR PATIENTS INTO MANIA
SNRI: Drugs - correct answer Serotonin Norepinepherine Reuptake Inhibitors
Venlafaxine
Desvenlafaxine
Duloxetine
SNRI: what do they do? - correct answer Increase both serotonin and norpinephrine in
the synapse by inhibiting neuronal uptake.
Used for depression and anxiety.
Benificial effects on neuropathic pain.
SNRI: side effects - correct answer Same as SSRI's, but also excessive sweating,
increase in blood pressure and heart rate.
MONITOR BP AND HR
Tricyclic antidepressants: Drugs (TCA's) - correct answer Nortriptyline
Amitriptyline
TCA's: what do they do? - correct answer Work on same transmitters and SNRI's. Block
serotonin and norepinepherine.
Treat anxiety, depression, migraine headache, neuropathic pain.
