MN 551 Week 7 Quiz
Question 1. 1. Following a long history of fatigue, weakness, and poor appetite, a 39-year-old male has been diagnosed with hypopituitarism. Which of the following clinical findings would most likely cause his care team to suspect that the man has an additional endocrine disorder from a different source? (Points : 2)

The man has a chronic platelet deficiency and is occasionally anemic.
The patient is 5 feet 2 inches tall and was consistently short for his age as a child.
The man displays the signs and symptoms of hypothyroidism.
Question 2. 2. A 79-year-old male resident of a long-term care facility has contracted Clostridium difficile and is experiencing consequent diarrhea. Auscultation of the man's abdomen indicates hyperactive bowel sounds. What processes in the man's small intestine are most likely accompanying his current status? (Points : 2)
Pathogenic microorganisms are causing dilation of his small intestine, increasing motility.
Segmentation waves have become more frequent as a result of his infection.
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.”

A 51-year-old woman who has been receiving estrogen and progesterone therapy (EPT) for the last 5 years has visited her care provider because her peers have told her about the risks of heart disease, stroke, and breast cancer that could accompany hormone therapy (HT). 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?

“Your daughter has lost all her cognitive functions as well as all her basic reflexes.”
“Though she still goes through a cycle of sleeping and waking, her condition is unlikely to change.”
“If you or the care team notice any spontaneous eye opening, then we will change our treatment plan.
“Your daughter's condition is an unfortunate combination of total loss of consciousness with continuation of all other normal brain functions.”

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)
