1. Which dopamine pathway is primarily associated with the positive symptoms of
schizophrenia, such as hallucinations and delusions?
A. Nigrostriatal pathway
B. Mesocortical pathway
C. Mesolimbic pathway
D. Tuberoinfundibular pathway
Answer: C
Conceptual Explanation: The mesolimbic pathway, projecting from the ventral tegmental
area to the nucleus accumbens, is associated with reward and the positive symptoms of
schizophrenia when dopamine is excessive.
2. A patient taking an SSRI presents with myoclonus, hyperreflexia, and diaphoresis. What is
the most likely diagnosis?
A. Neuroleptic Malignant Syndrome
B. Hypertensive Crisis
,C. Anticholinergic Toxicity
D. Serotonin Syndrome
Answer: D
Conceptual Explanation: Serotonin syndrome is characterized by neuromuscular
hyperactivity (myoclonus, hyperreflexia) and autonomic instability, often occurring when
two serotonergic agents are combined.
3. What is the therapeutic range for Lithium in the maintenance phase of bipolar disorder
treatment?
A. 0.6 to 1.2 mEq/L
B. 0.4 to 0.8 mEq/L
C. 1.0 to 1.5 mEq/L
D. 1.5 to 2.0 mEq/L
Answer: A
Conceptual Explanation: For maintenance, 0.6 to 1.2 mEq/L is generally considered the
therapeutic range. Acute mania may require levels up to 1.5 mEq/L.
4. Which neurotransmitter is the primary inhibitory messenger in the central nervous
system?
A. GABA
B. Dopamine
, C. Glutamate
D. Norepinephrine
Answer: A
Conceptual Explanation: Gamma-aminobutyric acid (GABA) is the chief inhibitory
neurotransmitter in the mammalian central nervous system.
5. Based on the Tarasoff v. Regents of the University of California case, what is the NP’s legal
obligation?
A. Maintain absolute confidentiality under all circumstances
B. Duty to warn and protect an identifiable third party from harm
C. Inform the police but not the victim
D. Wait for a court order before disclosing information
Answer: B
Conceptual Explanation: The Tarasoff case established that mental health professionals
have a ‘duty to warn’ potential victims of violence.
6. Which ethical principle refers to the NP’s duty to act in the best interest of the patient?
A. Autonomy
B. Beneficence
C. Justice
