Jolie calculates dosages and dilutions for medication dispensing. Which standard is she potentially violating?

a) Jolie should not wear a lead vest because it interacts with nuclear material; she only needs goggles for face protection.

b) Jolie is using a lab that is not isolated from other people.

c) Jolie does not need to perform dosage and dilution calculations; the pharmacist will handle that.

d) Jolie is not required to wear a face mask; nuclear material will not harm her face.
