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.
The medical Assistant should apologize for the inconvenience and explain to the patients in the waiting room that there was an emergancy at the hospital and reschedule their appointments.<span />
Hydrogenation of vegetable oils and animal fats is a standard industrial procedure. The more saturated a fat is, the longer its shelf-life. Why? Because a site of unsaturation, an olefinic bond, is potentially a reactive site that can be oxidized.
Of course, these days we are sold on the benefits of unsaturated fats. A priori, an unsaturated fat will yield less energy upon combustion, and the <span>C=C</span> double bond is harder to metabolize than <span>C−H</span> bonds.
