- Joe had experienced a recent respiratory infection but felt he was responding well to over-the-counter medications. He still had a low-grade fever, however. He was awakened during the night with pain in the thoracic region. Fearful that the symptoms might indicate a heart attack, he called 911 and was transported to the emergency department. On the way to the hospital, the paramedic advised Joe that his EKG was normal. After all tests for cardiac illness and pathology returned negative, Joe was sent home on antibiotics, pain medication, and with recommended bed rest. From your study of tissues and membranes, what might be the reason for this treatment? Explain your answer in 4 to 5 sentences. Indicate the reference/s of your answer.Mr. Sampang, a male in his upper 20’s stumbled to the ground as he sustained a single gunshot wound in the right portion of the abdomen from a stray bullet suspected of coming from a neighbor having a party celebration. He was rushed to a nearby hospital where it has been assessed that he lost a significant amount of blood as a result of the incident.The initial intervention was given to control bleeding but was assessed of decreasing blood pressure and an increased heart rate. Following blood transfusion, an increase in the patient’s blood pressure, and a decrease in his heart rate were observed. 1. Is the situation related to a negative- or positive-feedback mechanism? Explain.2. Identify and explain the processes involved in the occurrence of the signs and symptoms?3. Describe homeostasis and the components of feedback mechanism and its role/s in the occurrence of the related symptoms in the scenario.Mr. John Doe, a 72-year-old male with a long-standing history of chronic heart failure attributed to ischemic heart disease, was brought to the emergency department by his family due to increasing episodes of shortness of breath, especially at night, and swelling in his legs over the past week. Mr. Doe has been managing his condition with a regimen of ACE inhibitors, beta-blockers, and loop diuretics. Despite his adherence to medication, he has experienced gradual weight gain and decreased urine output in the days leading up to his presentation. His medical history is also significant for type 2 diabetes mellitus, controlled with oral hypoglycemics, and hypertension. On physical examination, Mr. Doe appeared visibly distressed, with labored breathing at rest, using accessory muscles. His blood pressure was noted to be 160/90 mmHg, with a heart rate of 98 beats per minute, respiratory rate of 26 breaths per minute, and oxygen saturation of 89% on room air. Bilateral pitting edema was…
- While downhill skiing, Jerry lost control and appeared to hit into a tree, chest first. The ski patrol that are also certified in EMT reported that Jerry was found with his head cocked at a peculiar angle and it looked like he had a fracture at the position of the C2 vertebra. During triage, Jerry appeared cyanotic and apneic. His heart was still beating, but his pulse was fast and thready. a) Explain how the described angle of the head might contribute to the loss of breathingb) What would be the best possible explanation for the cyanosis? Jerry was artificially ventilated and survives the transport to the hospital. Upon admission, the following notes were taken by the trauma team nurse. Right thorax compressed with ribs 7 to 9 fractured Right lung pneumothorax; trachea deviation to the left c) Describe the causes of pneumothrax and why this condition would result in the right lung to collapse? d) Why hasn't the left lung collapse? e) The physician inserts a chest tube into the…While downhill skiing, Jerry lost control and appeared to hit into a tree, chest first.

- ohn, an overweight 49-year-old man with history of diabetes and hypertension is playing soccer. After half an hour of an intense game, he feels severe chest pain that travels to his lower jaw. He is pale, diaphoretic, and short in breath. Upon arrival to the ER, an ECG was taken and the results show the following (note the changes in leads II, III and aVF): What could be the possible reason for John’s chest pain? Explain your answer based on the clinical information.72. The nurse notices that the client has a hematocrit of 70 percent. This level of hematocrit will most likely affect the vital signs in which of the following ways?A. The blood pressure will be elevated. B. The pulse will be low.C. Temperature will be elevated.D. Blood pressure will be low.Aspirin is cardioprotective for its anti-thrombotic properties, which means that it prevents platelets from coagulating to make a clot. In cardiovascular practice, aspirin is prescribed to help prevent heart attacks and strokes. Which of the following is true?

Right thorax compressed with ribs 7 to 9 fractured Right lung pneumothorax; trachea deviation to the left c) Describe the causes of pneumothorax and why this condition would result in the right lung collapsing?A mother calls in requesting an appointment for her son who has mentioned that he has had experienced some chest pain, lightheadedness, occasional palpitations, and slight episodes of shortness of breath. She also relates that he appears to be experiencing fatigue and reduced tolerance of activity. One of his fraternal uncles was diagnosed as having hypertrophic cardiomyopathy and had experienced similar symptoms before collapsing during a football game. She advised that she is very frightened, because her son wants to go back to school and participate in basketball. How do you handle this phone call? Recognizing the importance of the fact that the fraternal uncle was diagnosed with hypertrophic cardiomyopathy, you review information about the condition. What types of diagnostic procedures would you anticipate being ordered to be performed? What results would indicate the presence of hypertrophic cardiomyopathy? If the resulting diagnosis is hypertrophic cardiomyopathy, what…Bob is sitting outside on a warm day and is sweating pro- fusely. His friend Mary wants to practice taking blood pres- sures, and he agrees to play patient. Mary finds that Bob’s blood pressure is elevated, even though he is resting and has lost fluid from sweating. (She reasons that fluid loss should lower blood volume and, thus, blood pressure.) Mary asks you why Bob’s blood pressure is high instead of low. What should you tell her?
