Crystal violet is actually the primary stain used in the Gram Stain procedure to initially color all cells. Methyl alcohol is the decolorizer that removes the crystal violet from certain cell types. Safranin is the counterstain used to stain those cells that did not retain the crystal violet stain after the decolorization step.

Rationale: When examining a 6-year-old child, it is important to consider their sense of modesty. The child should undress themselves, leaving underpants on and using a gown or drape to maintain privacy. Additionally, a school-age child like a 6-year-old is curious about how equipment works, so it is beneficial to explain the purpose and function of the tools being used. The examination sequence should typically progress from the child's head to the toes to ensure a thorough assessment.
Therefore, choices A, B, and D are incorrect as they do not align with the appropriate approach to examining a 6-year-old child.
