What should the PMHNP consider when prescribing chemical restraints?
Correct Answer: Allergy status, prior medication history for adverse drug reactions related to the
medications ordered in the chemical restraint, and state regulations regarding chemical restraints
must be reviewed.
1. Chemical restraints (emergency medication for agitation/aggression) require careful consideration of
patient safety, medical history, and legal parameters.
2. State laws vary on what medications qualify, documentation requirements, and time limits (e.g., many
states require order renewal every 2-4 hours).
How does reviewing the genetic makeup of a client help guide the PMHNP in selecting
medication for clients?
Correct Answer: Genetic testing can assist by providing more information on how clients may
respond to certain psychotropic medications. Provides information on how a client may break down
and metabolize medications based on the cytochrome P450 system.
1. Pharmacogenomic testing (CYP450 genotyping) identifies poor, extensive, or rapid metabolizers.
Example: CYP2D6 poor metabolizers may need lower doses of risperidone, fluoxetine, or venlafaxine.
2. Not yet standard of care for all patients, but useful for treatment-resistant cases, those with prior
adverse reactions, or to guide dosing.
, Why might identical twins have different mental health outcomes despite 100% identical DNA?
Correct Answer: Both environmental and psychosocial stressors can impact mental health.
Although twins may have identical genes, their gene expression may be different. There may be an
environmental exposure that turned a gene "on" that should have been "off" for one twin to develop
schizophrenia and not the other.
1. Epigenetic mechanisms (DNA methylation, histone modification) alter gene expression without
changing DNA sequence. Environmental factors (trauma, infection, nutrition, stress) trigger these
changes.
2. Danish twin studies show 50% concordance for schizophrenia in identical twins (not 100%), indicating
significant environmental contribution.
Brain Anatomy – Central Sulcus function?
Correct Answer: Separates the frontal lobe from the parietal lobe.
1. Central sulcus (Rolandic fissure) divides primary motor cortex (precentral gyrus) from primary
somatosensory cortex (postcentral gyrus).
Frontal lobe functions
Correct Answer: Associated with movement, intelligence, abstract thinking, ability to organize,
personality, behavior, and emotional control.
1. Prefrontal cortex: executive function, decision-making, impulse control. Damage leads to personality
changes, apathy, disinhibition, poor judgment.
Broca's area function
Correct Answer: Speech production (expressive language).
1. Located in left frontal lobe. Broca's aphasia: non-fluent, effortful speech, preserved comprehension.
Temporal lobe functions
Correct Answer: Involves object identification and auditory signals (also contains limbic system,
amygdala, hippocampus; disorders include dementia and ADHD).
1. Primary auditory cortex (Heschl's gyrus), Wernicke's area (speech comprehension), memory
processing.
Cerebellum function
Correct Answer: Coordination of voluntary movement, balance, posture, motor learning.
1. Cerebellar lesions cause ataxia, dysmetria, intention tremor, dysdiadochokinesia.
Wernicke's area function
Correct Answer: Speech comprehension (receptive language).
1. Located in left temporal lobe. Wernicke's aphasia: fluent but meaningless speech, poor
comprehension.
Occipital lobe function
Correct Answer: Primary visual area (visual processing, color, motion, depth perception). Seizures
here cause visual hallucinations (lines of color).
