Rationale: In this scenario, Mary's focus on her own needs and interests by asking the mother about her lost friend and hometown indicates a lack of therapeutic benefit for the child and family.

Rationale: To calculate the corrected age of a premature child, you need to adjust for the weeks of prematurity. In this case, the child was born at 30 weeks gestation. From May 2, 2014, to August 5, 2014, is a span of 14 weeks. Subtracting the 30 weeks of gestation from the total time passed (14 weeks) gives the corrected age, which is 14 - 30 = -16 weeks. Since negative weeks are not relevant here, the corrected age is 0 weeks, which is equivalent to 2 weeks.
