Final answer:
The student's comment that indicates a need for clarification is that the HepB vaccine and the hepatitis B immune globulin should be given simultaneously at separate sites within 12 hours of birth, not separately.
Step-by-step explanation:
The student's comment that indicates a need for clarification is A) "The infant will get the hepatitis B vaccine (HepB) and the hepatitis B immune globulin within 12 hours at birth at separate injection sites." The correct information is that the HepB vaccine and the hepatitis B immune globulin should be given simultaneously at separate sites within 12 hours of birth. This is done to provide maximum protection to the infant against hepatitis B.
The second dose of the HepB vaccine can be given at 1 to 2 months of age, as stated in comment B. The third dose should be given at least 16 weeks from the second dose, as stated in comment C. And the last dose in the series should not be given before age 24 weeks, as stated in comment D.
