Which of the following is a common sign that a patient may be in pain?

Patients experiencing pain often display observable signs that indicate their discomfort, and one of the most telling is their facial expressions and vocalizations, such as moaning. Various studies have shown that individuals in pain may furrow their brows, clench their teeth, or exhibit grimacing. These non-verbal cues can often signal that a person is in distress even if they do not verbally express it. Additionally, moaning can be an instinctual response to pain as the body seeks to cope with the sensation, further confirming the presence of pain. Recognizing these signs is crucial for caregivers and healthcare providers to ensure appropriate assessments and interventions are made for the patient's comfort and care.
