What is an example of a clinical sign?

A clinical sign refers to any objective evidence of disease that can be observed or measured by a healthcare professional during an examination. In this context, the finding of an irregular pulse rhythm by the general practitioner is an example of a clinical sign. This is an observable measurement obtained through physical examination and can indicate underlying health issues, such as arrhythmias or other cardiovascular conditions.

In contrast, the other options reflect subjective symptoms reported by the patient. Headaches, fatigue, and dizziness are all experiences that the patient shares and cannot be directly measured or observed by the healthcare provider. They rely on the patient's description and are not considered clinical signs in the same way that an observable physical examination finding is. Understanding the difference between subjective symptoms and objective clinical signs is crucial for accurate diagnosis and treatment planning in a clinical setting.
