A nurse practitioner is educating a patient with a recent diagnosis of diabetes about the roles that glucose and insulin play in the disease pathology and the fact that glucose must enter the cell in order to provide energy for the patient. The nurse practitioner knows that which of the following processes allows glucose to enter body cells (Points : 0.4)
        Osmosis
        Facilitated diffusion
        Active transport
        Diffusion
 
 
Question 2.2. As part of an orientation to a genetic counseling practice, a group of medical students is differentiating between autosomal recessive disorders and autosomal dominant disorders. Which of the following statements is true of autosomal recessive disorders? (Points : 0.4)
        They can manifest when present in one or both gene pairs.
        *There is a one in two chance of an affected child in each pregnancy with an affected mother.
        They tend to have a more uniform symptomatology than autosomal dominant disorders.
        The associated disorders are usually attributable to abnormalities in structural proteins.
 
 
Question 3.3. A woman is surprised to read on the Internet that certain infections can cause cancer and has sought clarification from her nurse practitioner during an office visit. How can the NP best respond to the woman’s query? (Points : 0.4)
        *“Though it’s not particularly common, it’s true that certain bacteria and viruses can lead to cancer.”
        “Most cancers that cannot be attributed to family history or lifestyle are in fact associated with viruses.”

        “There are many viruses, but only a very few of them have been shown to cause cancer in humans.”
        “This is true; for example, HIV has been shown to cause cancer in some patients.”
 
 
Question 4.4. Which of the following statements most accurately conveys an aspect of cell injury due to impaired calcium homeostasis? (Points : 0.4)
        Normal intracellular calcium ion levels are higher than extracellular levels.
        Ischemia and certain toxins cause a decrease in cytosolic calcium.
        *Injured cells tend to accumulate calcium.
        Low calcium levels cause an activation of damaging enzymes.
 
 
Question 5.5. A 77-year-old male patient with a diagnosis of stomach cancer has been found to have metastases in his liver. The patient and his family are surprised at this turn of events, stating that they don’t see how he could have developed cancer in his liver. Which of the following facts would underlie the reply that the care team provides? (Points : 0.4)
        The parenchymal tissue of the liver is particularly susceptible to secondary malignancies.
        The portal circulatory system brings venous blood from the gastrointestinal tract into the liver.
        Hepatic stromal tissue shares characteristics with cancerous cells, including lack of anchorage dependence.
        *The proximity of the liver to the stomach allows for direct spread of cancerous cells due to a lack of contact inhibition.

 
 
Question 6.6. A group of researchers has identified that the prevalence of two particular genetic disorders share a statistical correlation. Which of the following statements best conveys the genetic rationale for this situation? (Points : 0.4)
        There is likely a cause-and-effect relationship between the two genes responsible.
        The chromosomes containing each gene are likely closely situated.
        *The genes causing each disorder are likely in the same section of the same chromosome.
        The disorders likely share the same locus.
 
 
Question 7.7. A nurse practitioner employed in a hospitalist notices that a patient is experiencing muscle atrophy following 2 weeks in traction after a motor vehicle accident. Which of the following factors has most likely contributed to the atrophy of the patient’s muscle cells? (Points : 0.4)
        High levels of insulin and IGF-1 in the patient’s blood during immobilization
        Denervation of the affected muscles during the time of traction
        A reduction of skeletal muscle use secondary to the traction treatment
        *Reduced oxygen consumption and cellular function that ensures muscle cell survival
 
 
Question 8.8. A researcher is involved in the production of insulin through recombinant DNA technology. Which of the following statements could the researcher best provide as a rationale for her work? (Points : 0.4)
        The gene fragment responsible for insulin production can be isolated and reproduced.
        Particular bacteria are capable of insulin production.
        It is possible to reproduce the chromosome responsible for insulin production.
