What does 'ambulate' mean in a medical context?

In a medical context, 'ambulate' specifically refers to the act of walking or moving from one place to another. This term is commonly used in healthcare settings to describe a patient’s ability to walk independently or with assistance after a medical procedure, injury, or illness. Encouraging ambulation is important for recovery as it helps improve circulation, respiratory function, and overall physical health.

The other options involve different aspects of patient care: ensuring hydration is essential for maintaining fluid balance, measuring vital signs provides critical information about a patient's condition, and assessing pain is crucial for evaluating the patient’s comfort and response to treatment. However, none of these terms convey the specific action of walking, which is the core meaning of 'ambulate'.
