Talc (1), the softest mineral on the Mohs scale has a hardness greater than gypsum (2) in the direction that is perpendicular to the cleavage. Diamonds (10) also show a variation in hardness (the octahedral faces are harder than the cube faces).
The Ambulatory Surgery Unit (ASU) is a multifaceted unit. A preoperative (preop) nurse assesses outpatients prior to the day of surgery. This is done at the ASU preop clinic visit and again on the day of surgery. The ASU RN assures the patient meets health and nursing criteria prior to surgery.
Ambulatory blood pressure monitoring is a noninvasive, automated process that records blood pressure over an extended period. Typically, readings are taken every 15 to 30 minutes for 24 hours, with around 50 to 100 readings in total. Data from the device are downloaded into software and can be translated into a report.
