Correct Answer
Explanation
A definite past history of chickenpox or shingles, or receipt of two doses of varicella vaccine, is normally sufficient to assume immunity. In a woman who is not otherwise immunosuppressed, serological testing or post-exposure prophylaxis is therefore not required solely because she has had another exposure.
Option Validity
A) VZV IgG testing is principally required when immunity is uncertain or in specified immunosuppressed women.
B) PEP is for susceptible non-immune women after significant exposure.
C) VZIG is not indicated when immunity can reasonably be assumed.
E) The extended potentially infectious period applies to susceptible exposed women receiving VZIG, not an immune woman.
F) Varicella vaccination is not given during pregnancy.
G) Amniocentesis is not indicated following exposure in an immune woman.
H) Fetal medicine surveillance is indicated after maternal chickenpox, not simple exposure in an immune woman.
