What is the full meaning of 'ICU'?

  1. International Chemistry Unit

  2. Intensive care unit

  3. Internal Central University

  4. Intra-Cellular Unit

The correct answer is: Intensive care unit

ICU stands for Intensive Care Unit, a specialized unit in hospitals for patients who require intensive medical treatment and monitoring. The other options do not accurately represent what ICU stands for or its purpose. A is incorrect as it refers to a unit of measurement in chemistry. C is incorrect as it does not accurately represent an actual university. D is incorrect as it refers to a fictional unit. Overall, the correct answer is the only option that accurately describes what 'ICU' stands for.
