Parachute jump - Research Paper Example From the Newton laws of motion, a free fall is the motion which involves the weight of a body as the only body is the only force that acts against it. Gravitation was reduced to a time space curvature. Felix had no force acting against him and hence moved along a geodesic. Due to absence of any other forces, gravitation acted on him equally due to the relative weightlessness. In this condition the gravitation field is zero. Felix in the free fall experienced gravititation "0-g". The Newton’s law of universal gravitation simplifies the dynamical equations that describe the trajectories that result due to gravitational force under normal conditions as F = mg. This accounts for the assumption for objects falling to earth over relatively short vertical distances. It is however much untrue over larger distances. The equation ignores the air resistance that was involved that has an effect on falling objects within appreciable distance in air causing them to approach a terminal velocity quickly. The air resistance effect varied enormously due to the size of Felix. The equation ignores the rotation of the earth failing to describe the Coriolis effect (Heitzmann, 23) Near the surface of the Earth, g  =  9.8  m/s ². The assumption is that SI unit g is measured in mps therefore d has to be measured in meters and time t in seconds. Therefore, velocity v is measured in meters per seconds(Heitzmann, 26) Felix is assumed to have started from rest and air resistance was neglected. In the Earth’s atmosphere all results are inaccurate after the first five seconds of the fall. Felix’s velocity at the time should have been a little less than the vacuum vale of 49 m/s due to the resistance of air. As Felix was falling through the atmosphere (which is not a perfect vacuum) therefore, he did not encounter a drag force brought about by air resistance. The drag force should have increased the velocity of the free fall. Felix therefore reached a state where the drag force

Clinical Scenario with Structured Questions Essay

Clinical Scenario with Structured Questions - Essay Example A nurse’s aid who is also a second year nursing student at university saw the client , took his blood pressure which was found to be elevated at 185/112. His heart rate was rapid at 113 beats per minute. The clinical picture indicated that the man was most probably having a heart attack. The student / nurse called an ambulance. As per unit protocol an accident/incident form was filled. Chest pain is a common occurrence with older patients. In the Emergency Department, chest pain needs to be isolated as cardiac or non-cardiac in origin. Physical assessment and proper history taking is very important in identifying the type of chest pain the patient is experiencing. This will also help the health care provider prioritize the plan of care. Proper assessment and history taking through detailed interview could have helped greatly in avoiding errors and reducing incidence reporting. This also indicates that the quality of care is improving. Pain is a very subjective matter. McCaffre y defined pain as whatever the person experiencing pain says it is, existing whenever the person communicates or demonstrates it does (McCaffrey, 1986). Chest pain is one of the most common complaints in emergency departments of hospitals and acute care centers, so common that immediate evaluation and correct diagnosis is very important in the patient’s survival. The situation describes a 44 year old Anglo-Saxon male client presenting with crushing chest pain. History shows long term use of alcohol, obesity, diabetic with insulin infusion, diaphoresis and shortness of breath. The Registered Nurse who first assessed the patient missed critical information such as taking the vital signs of the patient. Vital signs, particularly blood pressure is very important in the assessment of pain. Increased blood pressure usually indicates severe pain (Cox). High blood pressure and tachycardia are symptoms of a heart attack. These symptoms plus the crushing chest pain, diaphoresis and s hortness of breath are warning signs of heart attack and is should be considered a medical emergency. Clinical Governance Clinical governance is a term used by the National Health Service to describe a systematic approach in maintaining high standards of care and aims to continually improve the quality of services delivered in the clinical practice environment. Clinical governance is defined as a framework which helps all clinicians – including nurses – to continuously improve quality and safeguard standards of care (Royal College of Nursing). The role of clinical governance in this situation is to correct any mistakes that the drug and alcohol detoxification unit failed to detect. The purpose of clinical governance is to maintain and improve standards of patient care. In this scenario, it will improve the inadequate partenership between and among health care professionals dealing with the patient. It will also improve delivery of health care in other elements of clini cal governance such as education and training, clinical audit, clinical effectiveness, research and development, openness and risk management. In education and training, the staff of the unit are equipped for drug and alcohol detoxification but they also need to continually update themselves with regards to medical cases in order for them to promptly idnetify life threatening symptoms such as mentioned in
