Which of the following is an example of objective information?

1. "Mr. Castillo’s blood pressure is 115/68."

2. "Mr. Castillo seems very anxious."

3. "Mr. Castillo states he feels dizzy."

4. "Mr. Castillo looks unwell."

The correct answer is: "Mr. Castillo’s blood pressure is 115/68."

Objective information refers to measurable and verifiable data that is based on observable phenomena. In healthcare, objective information is crucial for accurate assessments and documentation because it provides factual evidence that can be recorded and monitored. The statement "Mr. Castillo’s blood pressure is 115/68" is an example of objective information because it presents a concrete measurement that can be objectively verified through medical equipment, such as a sphygmomanometer. This blood pressure reading is specific, numerical, and can be documented and repeated, making it a trusted piece of information for healthcare providers in monitoring Mr. Castillo's health status. In contrast, the other options are more subjective in nature. For example, describing Mr. Castillo as "very anxious" is based on the caregiver’s interpretation of his demeanor, which can vary between observers. The statement that "Mr. Castillo states he feels dizzy" represents a subjective report from Mr. Castillo himself about his sensations, which may not be independently verified. Similarly, saying "Mr. Castillo looks unwell" relies on visual observation, which is also open to personal interpretation rather than a measurable standard.
