Questions: The nurse knows that which patient presentation is objective data? Pain Headache Temperature Lightheadedness

The answer is the third one: Temperature.

Explanation for each option:

1. Pain: This is subjective data because it is based on the patient's personal experience and cannot be measured directly by the nurse.

2. Headache: This is also subjective data as it relies on the patient's description and cannot be objectively measured by the nurse.

3. Temperature: This is objective data because it can be measured and quantified using a thermometer, providing a concrete and observable value.

4. Lightheadedness: This is subjective data since it is based on the patient's feeling and cannot be directly observed or measured by the nurse.

In summary, objective data refers to information that can be observed and measured by someone other than the patient, such as temperature, while subjective data is based on the patient's personal experience and feelings.
