The farther backward you can look, the farther forward you will see.___by Winston Churchill

Catch a cold

THE extraordinary success of Homo sapiens is a result of four things: intelligence, language, an ability to manipulate objects dexterously in order to make tools, and co-operation. Over the decades the anthropological spotlight has shifted from one to another of these as the prime mover of the package, and thus the fundament of the human condition. At the moment co-operation is the most fashionable subject of investigation. In particular, why are humans so willing to collaborate with unrelated strangers, even to the point of risking being cheated by people whose characters they cannot possibly know? Evidence from economic games played in the laboratory for real money suggests humans are both trusting of those they have no reason to expect they will ever see again, and surprisingly unwilling to cheat them—and that these phenomena are deeply ingrained in the species’s psychology. Existing theories of the evolution of trust depend either on the participants being relatives (and thus sharing genes) or on their relationship being long-term, with each keeping count to make sure the overall benefits of collaboration exceed the costs. Neither applies in the case of passing strangers, and that has led to speculation that something extraordinary, such as a need for extreme collaboration prompted by the emergence of warfare that uses weapons, has happened in recent human evolution to promote the emergence of an instinct for unconditional generosity.

The current generation of college students has grown up with the internet and plenty of technology, but surprisingly, that doesn’t mean they know how find the information they need for research papers. A two-year study by the Ethnographic Research in Illinois Academic Libraries Project concludes that students are so used to conducting simple searches on Google that they have a hard time doing more sophisticated research either online or in the library.

ICP [Intracranial Cranial Pressure] is the pressure inside the skull, brain tissue, and cerebrospinal fluid. It is the biggest thing associated to Neurology on Nclex. Once you understand ICP, you can apply it to many things. It is associated to any head problem. Here is an example:
Question: An 18-year-old client is admitted with a closed head injury sustained in  a MVA. His intracranial pressure [ICP] shows an upward trend. Which  intervention should the nurse perform first?
a- Reposition the client to avoid neck flexion
b- Administer 1 g Mannitol IV as ordered
c- Increase the ventilator’s respiratory rate to 20 breaths/minute
d- Administer 100mg of pentobarbital IV as ordered.

High BP in the liver [aka portal hypertension] forces collateral circulation to form. In other words, the liver is sick [full of scar tissue causing it to become bumpy and lumpy]; this causes the pressure inside the portal vein to go crazy because it’s having a lot of trouble pushing that blood FORWARD. So, the blood will start backing up and will try to find other ways to get to the heart - thus creating new circulation.
This new circulation forms in 3 places: stomach, esophagus [esophageal varices] and rectum [hemorrhoids].
