Q: A vaccine does not exist for which of the following condition?

(A). Hepatitis B
(B). Hepatitis C
(C). Tetanus
(D). Polio

Hepatitis results from the hepatitis C virus, which spreads primarily through the blood. Sexual contact with an infected person or reused of needles from an infected person are common routes of infection. A vaccine has not been developed yet for hepatitis C.
Vaccines for hepatitis B, varicella, influenza, measles, mumps, polio, rubella, and tetanus are available and required for health care professionals. Hepatitis B vaccination requires 3 injections (the second injection one month after the first, the third injection six months after the first).
A vaccine for hepatitis A also exists.
Vaccines (immunizations) are important as they protect both the patient and the health care

Answer: B. Hepatitis C

The dental hygiene boards are VERY demanding. You will be asked to pull out everything that you have learned during school. The exam is 9 hours for the NBDHE (US) and 4 hours for the NDHCE (Canada). Can you imagine how difficult it will be? That is why we seriously encourage you to use our Wake Up Memory Technique.

Wake Up Memory Technique (WMT) for the dental hygiene boards

Hepatitis C -> Hepatitis “See” -> imagine a scientist in a pharmaceutical company lab talking to his team: “let’s see if we can make a vaccine because we don’t have one yet”

Let’s learn 2 more important characteristics about hepatitis:

  • Hep B and C are transmissions through the blood (directly or indirectly)
  • HBV has been known to survive in dried blood at room temperature on environmental surfaces for at least 7 days

CDC guidelines for the dental office

It is most important that we go straight to the most trustable source, the CDC. Their site has a section dedicated to oral health. Infection Prevention and Control in Dental Settings is where I found the link for the Guidelines for Infection Control in Dental Care Settings – 2003. Here are some of the highlights:

  • OSHA requires that employers make hepatitis B vaccination available to all employees who have potential contact with blood.
  • Employers are also required to ensure that employees who decline to accept hepatitis B vaccination sign an appropriate declination statement.
  • HBV is transmitted by percutaneous or mucosal exposure to blood or body fluids of a person with either acute or chronic HBV infection.
  • Transmission of HBV from dentist to a patient has not been reported since 1987.
  • Hepatitis C virus appears not to be transmitted efficiently through occupational exposure to blood. Follow-up studies of HCP exposed to HCV-infected blood through percutaneous or other sharps injuries have determined a low incidence of seroconversion.

At StudentRDH, my team and I are always trying to go the extra miles to verify all the information in our dental hygiene boards (NBDHE, NDHCE) solution. Some students fail and that is the sad truth. We don’t want that to be you! Please make sure to review all 17 chapters in the dental hygiene national boards review at StudentRDH.com. Did you know we have a FREE trial?
