NSG 552 Psychopharmacology Exam
1 Wilkes Qs and Ans with Explanation
1. The study of the use of psychotropic medications in the treatment
of psychiatric disorders:
A) Psychopharmacology
Correct Answer A
Explanation: Psychopharmacology focuses on how drugs affect mental
health conditions.
2. The study of what the body does to drugs:
A) Pharmacokinetics
Correct Answer A
Explanation: Pharmacokinetics involves absorption, distribution,
metabolism, and excretion of drugs.
3. The study of what the drugs do to the body:
A) Pharmacodynamics
Correct Answer A
Explanation: Pharmacodynamics studies the effects of drugs on the
body and mechanisms of action.
,4. Involves the absorption, distribution, metabolism, and excretion of
meds:
A) First Pass Metabolism
Correct Answer A
Explanation: First pass metabolism refers to the initial processing of oral
medications in the liver.
5. Increase serum levels of other drugs that are substrates of that
enzyme:
A) Enzyme inhibitors will slow down metabolism causing toxic levels.
Correct Answer A
Explanation: Inhibitors reduce enzyme activity, leading to increased
drug levels.
6. Decreases serum levels of other drugs that are substrates of that
enzyme:
A) Enzyme inducers cause fast metabolism and create subtherapeutic
drug levels.
Correct Answer A
Explanation: Inducers increase enzyme activity, reducing drug levels.
7. Part of the brain that regulates powerful emotions such as fear,
rage, sexual desires:
A) Amygdala
,Correct Answer A
Explanation: The amygdala is key in emotional regulation.
8. The relay station for sensory information:
A) Thalamus
Correct Answer A
Explanation: The thalamus processes and relays sensory signals.
9. Essential for maintaining homeostasis, controls basic needs such as
sleep-wake cycles:
A) Hypothalamus
Correct Answer A
Explanation: The hypothalamus regulates vital functions like
temperature, hunger, and sleep.
10. This lobe is involved in executive functioning, high-order planning,
speech, and motivation:
A) Frontal Lobe / Prefrontal Cortex
Correct Answer A
Explanation: The prefrontal cortex governs complex cognitive functions.
11. Derived from Tryptophan and made in the Raphe Nuclei:
A) Serotonin
, Correct Answer A
Explanation: Serotonin is synthesized from tryptophan in the raphe
nuclei.
12. Made in the Locus Ceruleus and involved in the noradrenergic
pathways:
A) Norepinephrine
Correct Answer A
Explanation: Norepinephrine is produced in the locus ceruleus and
modulates alertness and arousal.
13. 90% of serotonin receptors are found in the:
A) GI tract
Correct Answer A
Explanation: Most serotonin receptors are located in the
gastrointestinal system.
14. Produced in the VTA (Ventral Tegmental Area) and involved in the
four major pathways:
A) Dopamine
Correct Answer A
Explanation: The VTA produces dopamine involved in reward pathways.
