AANP PMHNP CERTIFICATION EXAM COMPREHENSIVE QUESTION
BANK (200 QUESTIONS WITH ANSWERS AND RATIONALES)
Question 1
Which of the following is the primary mechanism of action of Selective
Serotonin Reuptake Inhibitors (SSRIs) in treating depression?
A) Blockade of postsynaptic dopamine receptors
B) Inhibition of monoamine oxidase enzyme
C) Antagonism of serotonin 5-HT2A receptors
D) Inhibition of presynaptic serotonin reuptake
E) Enhancement of norepinephrine release
Correct Answer: D
Rationale: SSRIs work by blocking the presynaptic serotonin transporter
(SERT), thereby increasing the concentration of serotonin in the
synaptic cleft and enhancing serotonergic neurotransmission.
Question 2
An adolescent patient is diagnosed with Major Depressive Disorder.
Which of the following FDA-approved medications is considered a first-
line treatment for depression in this age group?
A) Fluoxetine
B) Amitriptyline
C) Phenelzine
D) Bupropion
E) Venlafaxine
Correct Answer: A
Rationale: Fluoxetine is the only SSRI specifically FDA-approved for
Major Depressive Disorder in children and adolescents aged 8-18. Other
,SSRIs like escitalopram are also commonly used, but sertraline and
fluoxetine have the strongest evidence base for this population .
Question 3
During a well-child visit, a PMHNP is assessing the development of a 2-
year-old. Which of the following gross motor skills is expected to be
present at this age?
A) Walking up and down stairs with alternating feet
B) Standing on one foot for at least 5 seconds
C) Running and walking up stairs with assistance
D) Jumping rope
E) Walking backwards with heel-to-toe gait
Correct Answer: C
Rationale: By age 2, a child should be able to run and walk up stairs with
assistance. More complex skills like alternating feet on stairs and
standing on one foot are typical of a 3-4 year old. Jumping rope is a
school-age skill.
Question 4
A patient is taking Carbamazepine (Tegretol) for bipolar disorder. The
PMHNP is considering adding a hormonal birth control pill (BCP). What
is the primary concern regarding this medication combination?
A) Increased risk of thrombotic stroke
B) Increased risk of serotonin syndrome
C) Carbamazepine will increase BCP levels leading to toxicity
D) Carbamazepine will decrease BCP levels leading to reduced efficacy
E) BCP will increase carbamazepine levels leading to toxicity
Correct Answer: D
Rationale: Carbamazepine is a potent inducer of the CYP450 enzyme
,system (specifically 3A4). This induction speeds up the metabolism of
oral contraceptives, reducing their serum levels and effectiveness.
Question 5
A PMHNP is evaluating an older adult patient who is forgetful, has poor
concentration, and reports feeling "empty" and "hopeless." The PMHNP
suspects pseudo-dementia. Which of the following findings would best
support this diagnosis over a primary neurodegenerative disorder?
A) The presence of aphasia and apraxia
B) A family history of Alzheimer's disease
C) A sudden onset of symptoms following a stroke
D) Significant improvement in cognitive function after starting an
antidepressant
E) Atrophy of the medial temporal lobe on MRI
Correct Answer: D
Rationale: Pseudodementia refers to cognitive impairment that is
secondary to a major depressive episode in older adults. Unlike true
dementia, it is reversible, and symptoms improve when the underlying
depression is treated .
Question 6
A PMHNP is conducting a psychiatric evaluation. The patient reveals
that they have been experiencing auditory hallucinations for several
years. To explore the content of these hallucinations, which of the
following is the most appropriate initial question?
A) "Are you currently taking any medications for this?"
B) "Did your parents ever experience anything similar?"
C) "What exactly do the voices say to you?"
D) "Have you ever acted on the commands of the voices?"
E) "How often do you hear the voices?"
, Correct Answer: C
Rationale: Assessing the content of hallucinations is a critical part of the
psychiatric evaluation. Asking "What do the voices say?" is a direct and
open-ended question to elicit this information and assess for command
hallucinations or other dangerous content.
Question 7
According to the FDA, which of the following genetic tests is strongly
recommended before starting Carbamazepine in a patient of Asian
descent?
A) HLA-B1502
B) CYP2D6
C) HLA-B5801
D) CYP2C19
E) MTHFR
Correct Answer: A
Rationale: The HLA-B*1502 allele is strongly associated with an
increased risk of Stevens-Johnson syndrome (SJS) and toxic epidermal
necrolysis (TEN) in patients of Asian ancestry taking Carbamazepine.
The FDA recommends genetic screening for this allele prior to starting
treatment .
Question 8
What is the primary role of messenger RNA (mRNA) in the process of
protein synthesis?
A) To transport amino acids to the ribosome
B) To act as the structural component of the ribosome
C) To provide a binding site for the drug to exert its effect
D) To carry genetic code from DNA in the nucleus to the ribosome in the
cytoplasm
