MENTAL HEALTH ACROSS THE LIFESPAN I PRACTICUM WEEK 4 MIDTERM EXAM
2026/2027 | MOST TESTED | 50 VERIFIED Q&A | CHAMBERLAIN - A+ GRADED
INSTRUCTIONS
Select the single best answer for each question.
Each question has one correct answer and three plausible distractors.
Questions focus on neurobiology, psychiatric assessment, DSM-5 diagnostic criteria, depressive disorders,
bipolar disorders, anxiety disorders, PTSD, OCD, schizophrenia spectrum disorders, and personality
disorders.
Assume standard adult parameters unless otherwise specified.
SECTION I: NEUROBIOLOGY & NEUROTRANSMISSION (Questions 1–10)
Q1 (NR605-W4-01). Which neurotransmitter is primarily associated with the "fight or flight" response and is
a target for medications treating anxiety disorders?
A) Acetylcholine
B) Dopamine
C) Norepinephrine
D) Serotonin
Answer: C
Rationale: Norepinephrine is the primary neurotransmitter associated with the "fight or flight" response, and
is a target for medications treating anxiety disorders. Acetylcholine (A) is involved in muscle contraction and
memory. Dopamine (B) is associated with reward and psychosis. Serotonin (D) is associated with mood,
sleep, and appetite regulation.

Q2 (NR605-W4-02). Which dopamine pathway is primarily associated with reward, motivation, and
pleasure?
A) Mesolimbic pathway
B) Mesocortical pathway
C) Nigrostriatal pathway
D) Tuberoinfundibular pathway
Answer: A
Rationale: The mesolimbic pathway projects from the ventral tegmental area to the nucleus accumbens and is
associated with reward, motivation, and pleasure. Overactivity is implicated in psychosis and substance abuse;
antipsychotics block D2 receptors in this pathway. The mesocortical pathway (B) is associated with cognition
and executive function. The nigrostriatal pathway (C) is associated with motor control. The
tuberoinfundibular pathway (D) regulates prolactin secretion.

Q3 (NR605-W4-03). Which dopamine pathway is associated with motor control and is affected in Parkinson's
disease?
A) Mesolimbic pathway

D) Tuberoinfundibular pathway
Answer: C
Rationale: The nigrostriatal pathway projects from the substantia nigra to the striatum and is involved in
motor control. Degeneration of this pathway causes Parkinson's disease. Antipsychotics can cause
extrapyramidal symptoms by blocking D2 receptors in this pathway.

Q4 (NR605-W4-04). Which dopamine pathway regulates prolactin secretion?
A) Mesolimbic pathway
B) Mesocortical pathway
C) Nigrostriatal pathway
D) Tuberoinfundibular pathway
Answer: D
Rationale: The tuberoinfundibular pathway projects from the hypothalamus to the pituitary gland and inhibits
prolactin secretion. Antipsychotics that block D2 receptors in this pathway can cause hyperprolactinemia,
leading to galactorrhea, gynecomastia, and sexual dysfunction.

Q5 (NR605-W4-05). Serotonin is synthesized from which amino acid?
A) Tyrosine
B) Tryptophan
C) Glutamate
D) Histidine
Answer: B
Rationale: Serotonin (5-hydroxytryptamine) is synthesized from the amino acid tryptophan. Tryptophan is
converted to 5-HTP by tryptophan hydroxylase, then to serotonin by aromatic amino acid decarboxylase. Low
tryptophan levels are associated with depression. Tyrosine (A) is the precursor for dopamine and
norepinephrine. Glutamate (C) is the primary excitatory neurotransmitter. Histidine (D) is the precursor for
histamine.

Q6 (NR605-W4-06). Which enzyme is responsible for breaking down monoamine neurotransmitters in the
synaptic cleft?
A) Acetylcholinesterase
B) Monoamine oxidase (MAO)
C) Catechol-O-methyltransferase (COMT)
D) Tyrosine hydroxylase
