NR546 TEST PAPER 2026 QUESTIONS WITH
ANSWERS GRADED A+
◉ How does reviewing the genetic makeup of a client help guide the
PMHNP in selecting medication for clients? 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?
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. Answer: separates the frontal lobe from the parietal
lobe
◉ frontal lobe. Answer: associated with movement, intelligence, abstract
thinking
◉ broca's area. Answer: speech production
◉ temporal lobe. Answer: involves object identification and auditory
signals
◉ cerebellum. Answer: coordination
◉ wernicke's area. Answer: speech comprehension
◉ occipital lobe. Answer: primary visual area
◉ parietal lobe. Answer: keeps us alert to what is going on around us
◉ sensory cortex. Answer: pain, heat, and other sensations
◉ motor cortex. Answer: movement
