What should the PMHNP consider when prescribing chemical restraints? - correct answer --
allergy status
-prior med hx for adverse drug reactions r/t the meds ordered in the chemical restraint
-state regulations regarding chemical restrains must be reviewed
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.
Tanrıkulu and Erbaş (2020) investigated identical twins to determine the presence of an
inherited link for schizophrenia and why one twin may develop schizophrenia when the other
does not. When two people have 100% identical DNA, why don't both persons develop the
exact illnesses? Studies of identical Danish twins found that if one twin had schizophrenia, the
other twin had a 50% lifetime risk of developing schizophrenia (Lemvigh et al., 2020). Why is
there only half the risk? - 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.
central sulcus - correct answer -separates the frontal lobe from the parietal lobe
frontal lobe - correct answer -associated with movement, intelligence, abstract thinking
, broca's area - correct answer -speech production
temporal lobe - correct answer -involves object identification and auditory signals
cerebellum - correct answer -coordination
wernicke's area - correct answer -speech comprehension
occipital lobe - correct answer -primary visual area
parietal lobe - correct answer -keeps us alert to what is going on around us
sensory cortex - correct answer -pain, heat, and other sensations
motor cortex - correct answer -movement
hippocampus - correct answer -involved in both memory and anxiety
nucleus accumbens - correct answer -involved in the reward process
thalamus - correct answer -involved in sensory organ and motor command processing
striatum - correct answer -involved in complex motor actions, also links cognition to motor
actions
