The acronym 'I&O' relates to which of the following?

  1. Inert & Organic

  2. Infection & Outbreak

  3. Intake and output

  4. Information & Orientation

The correct answer is: Intake and output

I&O stands for "Intake and Output." This acronym is commonly used in the medical field to refer to the amount of fluids a patient is consuming and excreting. Option A, Inert & Organic, is incorrect because "inert" means lacking the ability or strength to move, and organic refers to living matter. Option B, Infection & Outbreak, is incorrect because I&O does not refer to specific medical conditions such as infections or outbreaks. Option D, Information & Orientation, is incorrect because I&O specifically refers to fluid intake and output, not general information or orientation.
