Until Mr. Jones’ diagnosis is confirmed, what should be a priority?
Correct Answer: C
Rationale: The correct answer is C: Preventing spread of infection to others. This is the priority because until Mr. Jones' diagnosis is confirmed, it is crucial to prevent potential transmission of any infectious diseases to others. Encouraging rest (choice A) and providing attractive meals (choice D) are important for overall well-being but not as critical as preventing the spread of infection. Monitoring intake and output (choice B) is important for assessing Mr. Jones' health status but does not directly address the potential risk of infecting others. Therefore, choice C is the most immediate priority to ensure the safety of others.
