Answer:
The Hemovac drain isn't compressed; instead it's fully expanded.
Explanation:
Hemovac is a drain that removes any blood or other fluids that may accumulate in an area where surgery has been performed. In order for this drain to function properly, it must be compressed, ie the hemovac must be compressed and not fully expanded for efficient drainage. For this reason, the nurse reports to the doctor that she has no report of any drainage to the patient.
