Final answer:
Anxiety, acute pain, and reduced mobility are all examples of subjective symptoms.
Step-by-step explanation:
The correct answer is A. Subjective. Anxiety, acute pain, and reduced mobility are all examples of symptoms. Symptoms are subjective experiences or feelings that cannot be clinically confirmed or objectively measured. They are based on the individual's perception and can vary from person to person.
Objective measures, on the other hand, are measurable and observable signs that can be clinically confirmed. These include vital signs like heart rate, blood pressure, or lab test results. In this case, anxiety, acute pain, and reduced mobility cannot be directly measured, but rather reported by the individual.
Therefore, the symptoms mentioned in the question fall under the category of subjective experiences and are considered subjective.
