Answer to Question 1
Correct Answer: 1
Rationale 1: Most vaccines are pregnancy category C drugs.
Rationale 2: Pregnancy category X indicates a direct link to fetal abnormalities, and this is not true for vaccines.
Rationale 3: Pregnancy category D refers to drugs that promote greater fetal risk than that caused by vaccines.
Rationale 4: Pregnancy category B refers to drugs that promote less fetal risk than do the vaccines.
Global Rationale: Although most vaccines are pregnancy category C, vaccinations are sometimes delayed in pregnant patients until after delivery to avoid any potential harm to the fetus. Pregnancy category X indicates a direct link to fetal abnormalities, and this is not true for vaccines. Pregnancy category D refers to drugs that promote greater fetal risk than that caused by vaccines. Pregnancy category B refers to drugs that promote less fetal risk than do the vaccines.
Answer to Question 2
Correct Answer: 1
Rationale 1: Allergy to neomycin is a contraindication to the administration of the MMR vaccine.
Rationale 2: Allergy to mold would affect other medications, primarily antibiotics.
Rationale 3: Allergy to yeast would affect administration of the hepatitis B vaccine.
Rationale 4: There is no reason to withhold MMR from a client who is allergic to milk.
Global Rationale: Persons reporting an allergy to neomycin or gelatin should not receive MMR because the vaccine contains these substances. Persons reporting egg allergy have a very low risk of allergic reaction but it is recommended that these patients be observed for 90 minutes following immunization. Allergy to mold, yeast, or milk does not preclude this vaccination.
