RD exam practice question: Principles of Dietetics

Principles of DieteticsDifficulty 2/5

A client says they know they should cut sodium but cannot see how to do it with their family's cooking. Which counselling approach fits best?

  1. ASet a specific sodium target and ask the client to record all intake
  2. BProvide a printed low-sodium food list and schedule a follow-up visit
  3. CExplore the barrier and elicit the client's own ideas before advising
  4. DExplain the pathophysiology of sodium and blood pressure in detail
Show answer and rationale

Correct: C. The client has knowledge but faces a practical and social barrier. Motivational interviewing directs you to explore ambivalence and evoke the client's own solutions before offering advice.

  • B — A handout adds information the client already has.
  • D — More pathophysiology does not address a practical barrier.
  • A — A target without a feasible method is unlikely to be met.
