A 40-year-old man who uses heroin intravenously was diagnosed with hepatitis C (HCV) 1 year ago and is now considered to have chronic viral hepatitis. Which of the following statements by the client to his care provider would warrant correction?
 
  A)
  I know the medications to treat this aren't fantastic, but at least there are some options for controlling the virus.
  B)
  It's at least a bit reassuring that my liver isn't undergoing damage when I'm not experiencing symptoms.
  C)
  Even though I'm sick, at least I won't feel sick most of the time.
  D)
  I'm not looking forward to all the side effects of the drug treatments for my HCV, but I hope I don't end up needing a liver transplant.

Question 2

Which of the following statements best captures the essence of a second messenger in the mechanisms of the endocrine system?
 
  A)
  Second messengers act as the intracellular signal that responds to the presence of a hormone.
  B)
  Endocrine-producing cells must release both a hormone and a second messenger in order to exert a distant effect.
  C)
  Second messengers act to supplement hormone effects on cell receptors when the desired hormonal effect must be either increased.
  D)
  Second messengers provide an alternative pathway for endocrine effects on a cell that bypass the normal receptor pathways.

Answer to Question 1

Ans:
B

Feedback:

Liver damage persists both during symptomatic and asymptomatic periods of acute viral hepatitis. Medications do exist for treatment of the disease, and asymptomatic periods are more common than symptomatic episodes. Side effects of drug treatment are common, and transplant is a potential end-stage treatment option.

Answer to Question 2

Ans:
A

Feedback:

Second messengers interact with hormones that cannot cross the cell membrane, and they mediate the ultimate effect on the cell. They are not produced by the hormone-producing cell, and they are necessary to bring about hormonal effects, not simply for increasing the intensity of the effect. They are not an alternative mechanism of effect but rather a prerequisite for certain hormonal effects on body cells.
