NURSE 660 EXAM 1 COMPREHENSIVE
EXAM SCRIPT 2026 FULL SOLUTIONS
GRADED A+
⩥ Selective attention is due to what area of the PFC malfunctioning?
Answer: dorsal ACC (anterior cingulate cortex)
⩥ sustained attention and problem solving linked to what area of the
brain? Answer: DLPFC
⩥ hyperactivity is linked to what area of the brain? Answer: prefrontal
motor cortex
⩥ what test assessing sustained attention? Answer: N-back test
⩥ where is sustained attention modulated in brain? Answer: CSTC loop
in the DLPFC
insufficient activation in the DLPFC can cause inattention
"sustaiNed attention- N back"
⩥ what test assesses selective attention? Answer: Stroop test
,"Selective, Stroop, Cingulate"
⩥ where in the brain is selective attention modulated? Answer: the
CSTC loop, Dorsal anterior cingulate cortex
⩥ issues with sustained attention are: Answer: difficulty completing
tasks
disorganization
trouble sustaining mental effort
⩥ issues with selective attention are: Answer: difficulty with detail
carless mistakes
not listening
losing things
being distracted
forgetting things
⩥ what part of the brain modulates impulsitivity? Answer: orbitofrontal
cortex
⩥ what symptoms of impulsitivity are observed? Answer: talking
excessively
, blurting things out
not waiting ones turn
interrupting
⩥ what part of the brain modulates hyperactivity? Answer: prefrontal
cortex
⩥ what are some key observations in the prefrontal cortex as it relates to
ADHD? Answer: orbitofrontal cortex (OFC)-- impulsivity and
hyperactivity
DLPFC/DaCC-- sustained/selective attention issues
⩥ how do NE and DA amounts manifest in relation to fatigue/anxiety?
Answer: too little NE and DA = fatigue
too much = anxiety
⩥ what two receptors in the PRC are thought to be involved with ADHD
treatment? Answer: alpha 2 a
D1
⩥ how does ADHD affect NE and DA levels? Answer: NE levels low,
signal reduced
