Which of the following statements indicates knowledge about a patient's health?

The statement that indicates knowledge about a patient's health is the one that comments on the hemoglobin level being within the normal range. This choice implies an understanding of the significance of the hemoglobin value in relation to normal health parameters. By stating that the hemoglobin level is 13 and falls within the normal range, it provides insight into the patient's overall health status, as hemoglobin levels can indicate conditions such as anemia or other health issues.

In the other statements, while they provide specific data points related to health measurements, they do not contextualize this data within a framework of normalcy or health assessment. Simply stating a hematocrit level or blood pressure is a snapshot of data but lacks an evaluation of its implications on the patient's health. Additionally, mentioning the hospital's occupancy rate is not directly related to any individual patient's health status and therefore does not convey knowledge about a specific patient's health.
