Q1 Question 1 of 50
A 34-year-old patient with bipolar I disorder is admitted to an inpatient psychiatric unit during
a manic episode. The patient is hyperverbal, has not slept in 72 hours, and is attempting to
leave the unit against medical advice. Which intervention should the PMHNP prioritize to
ensure patient safety?
A. Initiate a therapeutic one-to-one observation and place the patient on close monitoring.
B. Administer a PRN benzodiazepine and allow the patient to ambulate freely on the unit.
C. Engage the patient in cognitive behavioral therapy to address underlying thought distortions.
D. Contact the patient's family to obtain consent for involuntary medication administration.
Correct Answer: A
Rationale:
Safety is the highest priority for a manic patient with flight risk and severe sleep deprivation. One-to-one observation
prevents elopement and self-harm. Benzodiazepines alone do not address the underlying risk, and CBT is
inappropriate during acute mania. Family consent is not required for emergency safety interventions.
Q2 Question 2 of 50
A PMHNP is conducting a group therapy session on an acute inpatient unit. One member
begins to dominate the conversation, monopolizing time and causing other members to
withdraw. Which group therapeutic factor is most at risk in this scenario?
A. Universality
B. Altruism
C. Cohesiveness
D. Imitative behavior
Correct Answer: C
Rationale:
Cohesiveness, the sense of belonging and mutual support within the group, is most threatened when one member
dominates and others withdraw. Universality involves shared experiences, altruism is helping others, and imitative
behavior is modeling positive actions. None are as directly compromised by monopolization.

, Q3 Question 3 of 50
A 28-year-old veteran presents to the VA clinic with intrusive memories, hypervigilance, and
emotional numbness following three combat deployments. The PMHNP recognizes that the
patient's hyperarousal symptoms are most consistent with which neurobiological
mechanism?
A. Excessive GABAergic inhibition in the prefrontal cortex
B. Dysregulated noradrenergic activity in the locus coeruleus
C. Downregulation of dopamine D2 receptors in the mesolimbic pathway
D. Enhanced serotonergic transmission in the raphe nuclei
Correct Answer: B
Rationale:
PTSD hyperarousal and hypervigilance are linked to excessive noradrenergic signaling from the locus coeruleus,
which mediates the fight-or-flight response. GABAergic inhibition would produce sedation, not arousal. Dopamine D2
downregulation is associated with antipsychotic effects, and enhanced serotonin transmission would typically reduce
anxiety, not increase it.
Q4 Question 4 of 50
During a medication education session, a 52-year-old patient with schizophrenia asks why
the PMHNP prescribed a second-generation antipsychotic rather than a first-generation
agent. Which explanation best addresses the primary advantage of second-generation
antipsychotics?
A. They have a faster onset of action and provide immediate symptom relief within hours.
B. They demonstrate superior efficacy in treating the negative symptoms of schizophrenia.
C. They carry a significantly lower risk of extrapyramidal symptoms and tardive dyskinesia.
D. They require less frequent dosing and can be administered once every three months.
Correct Answer: C
Rationale:
Second-generation antipsychotics primarily differ from first-generation agents by their lower risk of extrapyramidal
symptoms and tardive dyskinesia due to more balanced dopamine and serotonin receptor activity. They do not have
faster onset, are not superior for negative symptoms, and dosing frequency varies by formulation for both classes.
