Which of the following signs indicates a patient might be ready to be discharged from PACU?

The indication that a patient might be ready to be discharged from the PACU is characterized by stable vital signs, alertness, and controlled pain levels.

Stable vital signs are essential in assessing a patient's recovery from anesthesia; they reflect the body's ability to maintain homeostasis after undergoing a procedure. Alertness shows that the patient is regaining consciousness and cognitive function, which is crucial before any discharge as it ensures that they can follow instructions and communicate effectively. Controlled pain levels indicate that the patient is managing their post-operative discomfort adequately, suggesting they are in a stable condition and can be safely transitioned out of the PACU to a lower acuity care setting or home.

In contrast, high blood pressure, drowsiness, and chronic pain would indicate potential complications and the need for further monitoring. Low oxygen saturation, confusion, and restlessness suggest inadequate recovery and possible respiratory or cognitive issues that could jeopardize patient safety. Similarly, an increase in heart rate, shivering, and severe nausea implies that the patient may be experiencing complications such as pain, anxiety, or reaction to anesthesia, which necessitate continued observation and treatment before discharge. Thus, option B is the most appropriate indication of a patient ready for discharge from the PACU.
