Answer to Question 1

Rationale: The nurse should explain to the mother that the child has probably developed a tolerance to Ritalin and may need a higher dosage. Methylphenidate is a central nervous system stimulant, and tolerance can develop rapidly. Physical and psychological dependence can also occur.
