Which of the following statements is an accurate descriptor of the role of viruses in human infections?
 
  A)
  Viruses have no genetic material of their own.
  B)
  Some viruses are capable of transforming normal host cells into malignant cells.
  C)
  Viruses are often implicated in cases of transmissible neurodegenerative diseases.
  D)
  Viruses require stimulation after a latent period before they are able to produce symptoms.

Question 2

In the ICU setting, a patient transported from surgery following open heart bypass grafting will likely have his core temperature measured by a/an
 
  A)
  rectal tube inserted to prevent evacuation from bowels while recovering from anesthesia.
  B)
  temperature probe taped behind his ear.
  C)
  esophageal flexible thermometer monitoring aorta distention.
  D)
  pulmonary artery catheter being used to measure cardiac output.

Answer to Question 1

Ans:
B

Feedback:

Viruses that are categorized as oncogenic are able to induce malignancy in host cells. Viruses have limited genetic material (either RNA or DNA), but no virus lacks genetic material. Transmissible neurodegenerative disease is associated with prions. Not all viruses include a latent period.

Answer to Question 2

Ans:
D

Feedback:

Core temperature may be obtained by a rectal tube, by using an esophageal flexible thermometer, from a pulmonary artery catheter used for thermodilution measurement of cardiac output, or from a urinary catheter with a thermosensor that measures the temperature of urine in the bladder. Since CABG patients have their core temperature decreased to the 80s, the pulmonary artery catheter is the best choice for measuring core temperature while they are still under the influence of anesthesia.
