Final answer:
The correct response to a senior nurse's therapy suggestion that seems incorrect is to politely express concerns and seek further clarification. The intern should evaluate the suggestion and consult other healthcare professionals if necessary.
Step-by-step explanation:
When faced with a situation where a senior nurse suggests a particular therapy that does not sound right to an intern, the most appropriate and professional approach would be to politely express concerns and seek further clarification (C). This approach ensures patient safety and professional integrity while respecting the experience of the senior nurse. The intern should evaluate the suggested therapy in light of current medical standards and evidence-based practices, possibly consulting with other healthcare professionals if necessary. Discussing the situation with an understanding of applied behavior analysis (ABA), social communication groups, social skills groups, occupational therapy, and medication options might provide further insight into the best course of action for the patient.
