Questions: an objective indication of disease that is measurable by health care personnel

The answer is the second one: an objective indication of disease that is measurable by health care personnel.

Explanation for each option:

1. Measurable by health care personnel: This option is incomplete as it does not specify what is being measured. It lacks the context of being an indication of disease.

2. An objective indication of disease that is measurable by health care personnel: This is the correct answer. A "sign" in medical terms refers to an objective indication of disease that can be observed and measured by health care personnel, such as a rash, fever, or elevated blood pressure.

3. An objective indication of disease: While this is partially correct, it does not specify that it is measurable by health care personnel, which is a key aspect of a medical sign.

4. Malaise and body aches: These are examples of symptoms, not signs. Symptoms are subjective indications of disease experienced by the patient.

5. A subjective indication of disease: This describes a symptom, not a sign. Symptoms are reported by the patient and cannot be directly measured by health care personnel.

In summary, a sign is an objective indication of disease that is measurable by health care personnel.
