Licensed Practical Nurse/Licensed Vocational Nurse (LPN/LVN) I. What They Do. Licensed Practical and Licensed Vocational Nurses (LPNs/LVNs) do not work independently, but are supervised by a Registered Nurse (RN). Physicians and RNs determine courses of patient care; an LPNâs job is to assist patients in carrying out these instructions.
Scorpius is a constellation in the southern hemisphere, located near the centre of the Milky Way galaxy. It was one of the constellations introduced by the Greek astronomer Ptolemy in the 2nd century. Scorpius represents the scorpion that stung and killed Orion, the mythical hunter who boasted that he could kill any wild animal. The Earth sent the scorpion to kill Orion after hearing what he had said.
The discovery of the Scorpius constellation is credited to the famous Greco-Egyptian astronomer Claudius Ptolemy. He documented it in the 2nd century CE. However, civilizations predating the Greeks may have known about Scorpius. Roughly 3,000 years before Ptolemy, it was known as The Scorpion by the Babylonians.
