“You need to remind yourself that this is a purely physical phenomenon that requires physical treatment.”

“Our challenge is to bring you relief but still treat the underlying back problem that your body is telling you about.”

“These pain signals your body is sending likely serve no real, useful, or protective function.”

Question 12. 12. Which of the following factors is most responsible for the fact that prefrontal lobotomy is no longer a common treatment for mental illness? (Points : 0.4)

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.

Anterograde and retrograde axonal transport allow for the communication of nerve impulses between a neuron and the central nervous system (CNS).

Materials can be transported to the nerve terminal by either fast or slow components.

The unidirectional nature of the axonal transport system protects the CNS against potential pathogens.

Axonal transport facilitates the movement of electrical impulses but precludes the transport of molecular materials.

Intestinal stasis brought on by infection is preventing his small intestine from sufficiently slowing the rate of motility.

Inflammation is accompanied by an increase in peristaltic movements of his small intestine.

Question 3. 3. A 51-year-old male professional is in the habit of consuming six to eight rum and cokes each evening after work. He assures the nurse practitioner, who is performing his regular physical exam, that his drinking is under control and does not have negative implications for his work or family life. How could the nurse best respond to the patient’s statement? (Points : 2)

“You are more than likely inflicting damage on your liver, but this damage would cease as soon as you quit drinking.

“That may be the case, but you are still creating a high risk of hepatitis A or B or liver cancer.”

“In spite of that, the amount of alcohol you are drinking is likely to result first in cirrhosis and, if you continue, in hepatitis or fatty liver changes.”

“When your body has to regularly break down that much alcohol, your blood and the functional cells in your liver accumulate a lot of potentially damaging toxic byproducts.”

How should her care provider respond to her concerns? (Points : 2)

“There is a demonstrable increase in breast cancer risk with HT, but the risk of stroke or heart disease actually goes down slightly.”

“All things considered, the benefits of HT outweigh the slightly increased risks of heart disease, stroke, or breast cancer.”

“HT is actually associated with a decrease in heart disease risk, but there is an increase in stroke risk; the breast cancer connection is still unclear.”

“There’s in fact a slight protective effect against stroke associated with HT, but this is partially offset by increased rates of heart disease and breast cancer.”

Question 6. 6. Chronic anxiety and stress contribute to ulcers. Which of the following effects of the sympathetic nervous system is most responsible for this effect?

The remaining primary follicles will provide hormonal support for the first 3 months of pregnancy.

The corpus luteum will atrophy and be replaced by corpus albicans.

The basal layer of the endometrium will be sloughed in preparation for implantation.

Question 11. 11. A patient with a history of an endocrine disorder exhibits signs and symptoms of hormone deficiency. Which of the following processes would the patient’s care team most likely rule out first as a contributing factor? (Points : 2)
