Health And Medicine- Viral Hepatitis Knowledge Test
(199).jpg "Health And Medicine- Viral Hepatitis Knowledge Test - Quiz")
Viral Hepatitis is an inflammation of the liver due to viral infection. Hepatotropic viruses such as hepatitis A, B, C, D, and E are common causes. If you are studying medicine, you might know about this inflammation. Let's see how much knowledge do you have about this.
- 1.
Which of the following statements about hepatitis A treatment is true?
- A.
There is no treatment specific for hepatitis A
- B.
Treatment should begin before symptom onset
- C.
IV antiviral therapy should be administered
- D.
Treatment can be discontinued once a patient has (+) IgG
Correct Answer
A. There is no treatment specific for hepatitis AExplanation
There actually is NO specific treatment for hepatitis A. If a patient was not tolerating their symptoms, they would simply receive supportive care.Rate this question:
-
- 2.
Which of the following confers PASSIVE immunity?
- A.
Hepatitis A vaccine
- B.
IgG
- C.
Hepatitis B vaccine
- D.
Hepatitis C vaccine
Correct Answer
B. IgGExplanation
Vaccines confer ACTIVE immunity, while directly giving a patient anti-bodies is known as passive immunity. There is no such thing as a hepatitis C vaccine.Rate this question:
-
- 3.
A patient is flying to Peru next week, but he is not sure if he has ever received a vaccine for hepatitis A. Which of the following should he receive (choose all that apply)?
- A.
Hepatitis A vaccine
- B.
IgG
- C.
IgM
Correct Answer(s)
A. Hepatitis A vaccine
B. IgGExplanation
Because the patient is traveling to a high endemic area (South America) in less than 2 weeks, they would receive BOTH the vaccine and IgG. IgM is not an antibody that is administered to patients.Rate this question:
-
- 4.
If a patient is positive for _____ Anti-HAV, this signifies that the patient currently has acute hepatitis A infection. (Answer is 3 letters)
Correct Answer(s)
IgMExplanation
Remember that IgM comes first and indicates current infection in hepatitis A. IgG would only come after a patient has recovered.Rate this question:
- 5.
Which of the following patients would have positive IgG Anti-HBc? (Choose all that apply)
- A.
A 23-year old recovered from hepatitis A infection
- B.
A 54 year old who has recovered from hepatitis B infection
- C.
A 67 year old in phase 4 of hepatitis B infection
- D.
A 78 year old in acute hepatitis B infection
Correct Answer(s)
B. A 54 year old who has recovered from hepatitis B infection
C. A 67 year old in phase 4 of hepatitis B infectionExplanation
Note that the question asked about Anti-HBc, which is specific to hepatitis B. In hepatitis B, the patient would only develop IgG after acute infection phase is done. So a patient who has recovered from HBV will have IgG Anti-HBc, and also a patient who has advanced to chronic illness will also have IgG Anti-HBc.Rate this question:
-
- 6.
In which TWO phases of hepatitis B is liver damage occurring?
- A.
Phase 1, 2
- B.
Phase 3, 5
- C.
Phase 2, 4
- D.
Phase 2, 3
Correct Answer
C. Phase 2, 4Explanation
Phase 2 and 4 are the only two phases where liver damage is occurring. This is why treatment is given for both of these phases.Rate this question:

Correct Answer(s)
C. IgG Anti-HBV
E. Anti-HBeExplanation
Not much here! This is the first and only phase where S Antigen is negative, which signifies functional cure. Notice that I did not give Anti-HBs as an option. That's because not everyone develops this antibody in phase 5, so Anti-HBs can be positive or negative in phase 5.Rate this question:
-
- 12.
Phase 1 Hepatitis B patients do not need to be treated, UNLESS _______________.
- A.
They are younger than 30
- B.
They are older than 30
- C.
They have elevated ALTs
- D.
They have extremely high levels of HBV DNA
Correct Answer
B. They are older than 30Explanation
Most phase 1 patients do not need to treated. The exception is patients >30 years of age since they will very likely advance to phase 2 soon. Technically if a patient has elevated ALT, they are no longer in phase 1 (no liver damage) and are now in phase 2.Rate this question:
-
- 13.
Phase 3 and Phase 5 hepatitis B patients do NOT need to continue treatment, UNLESS ______________.
- A.
They are still HBsAg positive
- B.
They have had hepatitis B infection for more than 10 years
- C.
They are tolerating treatment very well
- D.
They already have cirrhosis with any detectable virus
Correct Answer
D. They already have cirrhosis with any detectable virusExplanation
Phase 3 (remission) and phase 5 (functional cure) patients do not usually need to continue treatment. The exception is if they have already advanced to cirrhosis. In this case, these patients are still at risk for developing further complications of advanced liver disease. Plus, stopping a nucleoside analog can cause rebound hepatitis and the risk is worse in cirrhosis.Rate this question:

Correct Answer(s)
A. Ledipasvir/sofosbuvir
B. Elbasvir and Grazoprevir
D. Velpatasvir and SofosbuvirExplanation
The question asks which medications are safe to use with birth control containing ethinyl estradiol. The correct answer options are Ledipasvir/sofosbuvir, Elbasvir and Grazoprevir, and Velpatasvir and Sofosbuvir. These medications do not interact with ethinyl estradiol and can be safely used together.

Which of the following classes of medications will have minimal drug interactions with hepatitis C treatments?
- A.
Anti-histamines
- B.
Anti-hypertensives
- C.
Anti-convulsants
- D.
Anti-arrhythmics
Correct Answer
A. Anti-histaminesExplanation
Anti-histamines are the class of medications that will have minimal drug interactions with hepatitis C treatments. This is because anti-histamines primarily work on histamine receptors in the body and do not significantly interact with the liver enzymes that metabolize hepatitis C medications. On the other hand, anti-hypertensives, anti-convulsants, and anti-arrhythmics may have a higher likelihood of drug interactions with hepatitis C treatments due to their potential effects on liver enzymes or drug metabolism.Rate this question:

Which drug requires two forms of contraception during treatment and 6 months after treatment?
- A.
Harvoni
- B.

C. RibavirinExplanation
Ribavirin requires two forms of contraception during treatment and 6 months after treatment. This is because Ribavirin can cause birth defects or death in an unborn baby. Therefore, it is crucial for both men and women who are taking Ribavirin to use two effective forms of contraception to prevent pregnancy during treatment and for 6 months after treatment to ensure the safety of the baby.Rate this question:

- Levothyroxine
- A.
Harvoni
- B.
Mavyret
- C.
Epclusa
- D.
Zepatier
Correct Answer
C. EpclusaExplanation
Harvoni and Zepatier do not cover genotype 2. Mavyret should not be used due to its potential interaction with quetiapine, which is an anti-psychotic. Epclusa can be used safely with anti-psychotic. There are no drug interactions with metformin or thyroid hormone.Rate this question:

Which of the following medications should be taken with food
- A.
Epclusa
- B.
Zepatier
- C.
Harvoni
- D.
Mavyret
Correct Answer
D. MavyretExplanation
Mavyret should be taken with food because it contains a medication called glecaprevir, which is better absorbed when taken with a meal. Taking Mavyret with food helps to increase its effectiveness and ensures that the body can properly absorb the medication. This is why it is important to follow the instructions and take Mavyret with food.Rate this question:
