Which of the following factors is most responsible for the fact that prefrontal lobotomy is
no longer a common treatment for mental illness? - ANS-Individuals treated by
lobotomy have difficulty interpreting somatic, visual, and auditory information.
Lobotomy inhibits the individual's ability to add perception and meaning to sensory
information.
******Severing connections between the brain and its prefrontal areas inhibits problem
solving and results in a loss of ambition.
Loss of communication to and from the prefrontal cortex changes, but ultimately
exacerbates, symptoms of mental illness.
Which of the following questions is most likely to be clinically useful in the differential
diagnosis of sensorineural versus conductive hearing loss? - ANS-*******"What
medications do you currently take?"
"What effect is this hearing loss having on your quality of life?"
"Has your hearing loss developed quickly or more slowly?"
"Do you ever hear a persistent ringing in your ears?"
Four weeks ago, an 83-year-old male fractured his femoral head in a fall that was
caused by orthostatic hypotension. His care provider has stated that the healing
process is occurring at a reasonable pace, and that the man will regain full function after
healing and rehabilitation. Which of the following cells are most responsible for restoring
the integrity of the man's broken bone? - ANS-Osteocytes
Osteoclasts
*******Osteoblasts
Osteomas
, Which of the following individuals demonstrates a health problem with his or her axial
skeleton? - ANS-A 21-year-old male who fractured his humerus while snowboarding
*******A 40-year-old man who has a contusion to the left temporal bone of his skull
following a motor vehicle accident
A 79-year-old female who has undergone hemiarthroplasty (hip replacement surgery)
A 30-year-old pregnant woman who has a separated pubic symphysis
Which of the following statements most accurately characterizes an aspect of the
neurobiology of sleep? - ANS-The hypothalamus stimulates the anterior and posterior
pituitary to modulate sleeping-waking cycles.
The pituitary releases melatonin at predictable points in the circadian rhythm in order to
facilitate sleep.
The reticular formation, thalamus, and cerebral cortex interact to integrate the
sleep-wake cycle.
Input from the retinas is interpreted by the cerebellum and contributes to maintenance
of the circadian rhythm.
A woman with severe visual and auditory deficits is able to identify individuals by
running her fingers lightly over their face. Which of the following sources is most likely to
provide the input that allows for the woman's ability? - ANS-Pacinian corpuscles
Ruffini end organs
*******Meissner corpuscles
Free nerve endings
Which of the following patients on a hospital medical unit is most clearly demonstrating
the signs and symptoms of liver failure? - ANS-*******A 44-year-old man with low
hemoglobin levels, low platelet levels, and spider angiomas
A 50-year-old woman with blood pressure of 189/103, jaundice, and multiple
thromboses
