How to Find the Draco Constellation

Draco is a long, winding constellation easily visible to northern hemisphere observers. Its one of those star patterns that actually does look somewhat like its name, tracing out the long body of an exotic dragon across the sky.   Finding Draco Constellation Locating Draco is pretty easy in clear, dark skies. The best way is to first locate the north star Polaris, or look for the Big Dipper or the Little Dipper. They are on either side of the long body of the celestial dragon. Its head is at one end, near the constellation Hercules and its tail is up near the bowl of the Big Dipper.   This chart shows Draco in relation to nearby constellations of Ursa MInor (the Little Dipper) and Hercules.

They placed it close in the sky to the figure of Hercules. He was their mythical hero who, among many other notable actions, killed the dragon as one of his twelve labors.  Over the centuries, the Greeks spoke of Draco going after heroines, particularly the goddess Minerva, as well as his adventures as the son of the Titan Gaia. In contrast, the ancient Arabic astronomers saw this region of the sky as home to two hyenas attacking an infant camel who is part of a mother group of older camels. The Stars of Draco Constellation Draco has fourteen brighter stars that make up the body of the dragon, and many others that lie inside the official IAU-designated region for the constellation. Its brightest star is called Thuban, which was our north star at the time the ancient Egyptians were building their pyramids. In fact, the Egyptians angled certain passageways inside the pyramids to point directly at Thuban. Thuban existed in a region of the sky that they believed was a gateway to the afterlife.  Therefore, if the passageway pointed there, the soul of the pharaoh would have a direct pathway to his reward. The official IAU chart showing the region of the northern hemisphere sky that contains constellation Draco. IAU/Sky Publishing. Eventually, due to the procession of Earth on its axis, Thubans position in the sky changed. Today, Polaris is our north star, but Thuban will be the pole star again in about 21,000 years. Its name is derived from the Arabic term that means snake. This chart shows how Earths north pole precesses as Earth wobbles on its axis. The result is that the pole appears to point at different stars over the course of 26,000 years. Right now it points at Polaris, but in the past (and in the future) Thuban is a target.

The bright one we see is accompanied by a very faint star that orbits very close to its partner. The second-brightest star in Draco is called ÃŽ ² Draconis, with a familiar name of Rastaban. It is near the bright star ÃŽ ³ Draconis, which is also called Eltanin. Interestingly, Eltanin is actually the brightest star in Draco.   Deep-Sky Objects in Constellation Draco This region of the sky has a number of faint deep-sky objects that require binoculars or a telescope to see. One of the most famous is the Cats-Eye Nebula, also known as NGC 6543. Its a planetary nebula that lies about 3,000 light-years away from us and is the remains of a sun-like star that experienced its final death throes some 1,200 years ago. Before that, it gently blew off its material in a series of pulsations that formed concentric rings around the dying star.   The Cats Eye planetary nebula, as seen by Hubble Space Telescope. NASA/ESA/STScI The unusual shape of the nebula is due to the clouds of material blown away from the star by a fast stellar wind. It collides with material that was ejected earlier in the stars aging process. The cloud of material is mostly hydrogen and helium, mixed with other materials. Astronomers suspect there may have been a binary companion star involved, and interactions with it may have caused the complex structure we see in the nebula.   Viewing the Cats-Eye Nebula requires a good small- to medium-sized telescope, since its actually quite dim. The nebula was discovered by William Herschel in 1786 and has been observed by many professional astronomers using both ground-based instruments, the Hubble Space Telescope and the Chandra X-ray Observatory.   Observers with good telescopes can also spot several galaxies in Draco, as well as galaxy clusters and colliding galaxies. Its well worth a few evenings of exploration to ramble through Draco and spot these fascinating objects.

To organize a team that would be the first responders for all emergent situations, the team would include a leader, facilitator, recorder, time keeper, and team members. The leaders would be the primary URN and primary physician on the given case. The facilitator of this team would be the ICC nurse. The recorder and time keeper would be the same person being one of the unit staff members, not necessarily a URN but could be the charge nurse or resource nurse. The team member included could be the respiratory therapist who could help assists with necessary task if not preoccupied with a respiratory distress patient. In addition to these team members, I would include a security officer to be present and on standby for these patients that are combative and a possible threat to themselves or others. In this specific case the security team could have helped assist with the patient leaving the scene. C.

As stated previously in â€Å"letter a†, to improve the process and decrease the risk of this situation happening again a team should be implemented who is specifically trained in dealing with these situations. The emphasis should be placed on training and education for the staff and team members so this situation of staff not knowing how to respond or deal with this patient, will not happen again. A unit protocol should also be set in place, so that the staff does not have questions regarding how to deal with these patients in the future when this situation reoccurs. AAA. Improvement Plan In order to best be prepared in case this situation should happen again, a plan should be developed and in place so there is no questions as to whom should respond and what tasked should be taken. First there should be a team established and trained to be prepared for these situations.

Once the situation in diffused and handled, the recorder should chart all the details that occurred during the response and the team should debrief regarding how things were dealt with and improvements that could be made. AAA. Implementation In order to implement this plan, a team must be developed that is specifically trained to handle these emergent situations. Each member should have a specific role better educate the team members in dealing with these patients. The members should be educated in detail regarding the plan and how to carry it out.

Plan Measurement Evaluation of In order to measure and evaluate if the plan would be effective a â€Å"mock† emergency could be staged in order to gage and evaluate how the team members react and successfully carry out the process. To be measurable, the response time could be recorded in order to evaluate how long the team takes to respond to the emergency and how long it takes to secure and safely treat the patient. Evaluations on each team member could be done and reviewed in order to make further corrections if necessary. After each emergent situation a debriefing could be held to discuss the outcomes and areas that need to be improved in order to better the process each time. B. Unit Protocol 1). No staff member should approach the patient by themselves, always have second staff member present at all times. ). At first sign of behavioral outburst, call security team in for backup. 3). Call team overhead to alert all members at first signs of emergency, in order to initiate first steps of the developed process. 4). Never attempt to restrain the patient before or during behavioral episode without consulting MD first. 5). Do not risk putting yourself in way of harm of physical danger if patient in combative, a llow security team or police office to handle extreme cases of behavioral episodes.
