Some viruses are capable of transforming normal host cells into malignant cells.
C)
Viruses are often implicated in cases of transmissible neurodegenerative diseases.

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.
