Download file to see previous pages 1. Mr Robinson presented to the Emergency unit after vomiting a massive amount of blood. His current status represents a state of hypovolemic shock which was caused by a large amount of blood in his vomit.
Mild to moderate hypovolemia only leads to resting tachycardia, however blood loss of at least 50 per cent results in supine hypotension (Saltzman & Fieldman 2013). The loss of blood leads to reduced intravascular volume and inadequate tissue perfusion. This causes a reduced arterial pressure and decreased tissue perfusion; hence the tissues are deprived of oxygen and nutrients (Lippincott Williams & Wilkins 2009). Mr Robinson presented with increased blood urea nitrogen suggesting renal failure due to “a large quantity of blood” in his vomiting, pointing out towards the massive reduction in intravascular volume leading to hypovolemia.
Mr. Robinson’s initial presentation is consistent with the signs of hypovolemic shock and presented to the Emergency room with cold and clammy skin, tachycardia and anxiousness. His pulse was 130 beats per minute which were weak and thread in nature, exhibiting hypovolemia. As a compensatory effect, the respiratory rate is increased leading to hyperventilation, in an attempt to increase the partial pressure of oxygen in arterial blood. Mr. Robinson’s respiratory rate was 36 breaths per minute, suggesting that he was hyperventilating as a compensatory response to the metabolic acidosis.
 Acute upper gastrointestinal bleeding can present either as blood in vomiting (hematemesis) or melena (blood in stool). In the given case, the patient presents with massive upper GI blood loss through vomiting which leads to a medically critical state of hypovolemia. Approach to diagnosis of a medical case first revolves around the history of the patient. ...Download file to see next pages Read More

Drug Administration in Objective Structured Clinical Examination

...?Reflections on my Drug Administration OSCE Drug administration is one of the major roles of nurses. However, as I found out in the objective structured clinical examination (OSCE) given to us, it entails much more than simply giving a patient a pill. It is an aggregate of all the principles and skills we learn as nursing students, and the application of theories into practice. In drug administration, we have to remember and practice patient safety, provide holistic and individualized patient care, have a solid foundation on knowledge about drugs and medication safety, and perform administration checks and documentation at all times. Much about the role of nurses in hospital can be learned from something as seemingly simple as a drug...

Robinson Crusoe

...1. Essay Topic Robinson Crusoe and God's Providence Expediency or Salvation: Does Robinson Crusoe Believe in Divine Providence In Daniel Dafoe's Preface to 'The Life and Strange Surprising Adventures of Robinson Crusoe of York, Mariner...' he states that his intention is to ustify and honour the wisdom of Providence in all the variety of our circumstances.(xv). It is difficult to conclude that this is wholly fulfilled; the book may be interpreted on so many levels. On one, it seems to be a spiritual autobiography, showing the journey from sinner to saved, on another, a heroic adventure tale, and on yet another, a reflection on how to deal with the traumas of life and triumph over adversity. With so many facets, examining the book does...

Robinson Crusoe

...ROBINSON Daniel Defoe’s “Robinson Crusoe “stands alone in the array of literature of travel and adventure. This is the story of a human being who struggles hard for survival in an outlandish situation.

This story tells about the diverse ways in which a man muddles through reality when hardship comes and shaping his own world in absolutely alien circumstances. The text fairly deals with the relation between man and nature, man and culture, and his relation with God. Daniel Defoe had done a good job to bring Robinson...
