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.
When a patient needs medical attention without the need for admission, it is called ambulatory care. Ambulatory care includes several medical procedures or treatments that can be performed on an ambulatory basis. Blood tests, X-rays, endoscopy, biopsy and vaccination are some examples of ambulatory care. A baby visiting a pediatrician for a monthly checkup is also considered as ambulatory care.
