An occupational health clinic is conducting pre-employment medical screenings for newly hired healthcare personnel. A practical nurse is reviewing a client's health history prior to administering the first dose of the hepatitis B recombinant vaccine. Which finding is an absolute contraindication that requires the nurse to withhold the immunization?

  1. A
    Current pregnancy in the second trimester
  2. B
    A documented anaphylactic allergy to neomycin and gelatin
  3. A documented anaphylactic reaction to baker's yeastCevap
  4. D
    A mild, non-febrile upper respiratory tract infection

Cevap

A documented anaphylactic reaction to baker's yeast
The hepatitis B vaccine is produced using recombinant DNA technology in yeast cells. Therefore, a history of an anaphylactic reaction to baker's yeast is an absolute contraindication for receiving this specific immunization.

Adım Adım Çözüm

1
Identify the specific immunization being administered and its unique characteristics.
The scheduled immunization is the hepatitis B recombinant vaccine, which is an inactivated viral vaccine grown in yeast cultures.
Different vaccines have specific manufacturing processes that determine their absolute contraindications, such as specific allergens.
2
Evaluate each client finding in the options against the known contraindications for the hepatitis B vaccine.
Anaphylaxis to baker's yeast is a known absolute contraindication. Pregnancy, mild acute illnesses, and neomycin allergies are not contraindications for this specific vaccine.
Administering a vaccine to a client with a known anaphylactic allergy to its active components or culture medium can cause a life-threatening systemic reaction.
