Question:
Your patient experiences sudden changes in blood pressure and heart rate with a ventilator high-pressure alarm. You ask to obtain a chest X-ray, and it reveals that the trachea deviates to the left. The right side of the chest is completely black and translucent, and there is hypoventilation noted on the left. You check your Ett and notice it is in the right mainstem. What do you think is wrong?

- 1- A. How is the blood in the pulmonary artery and pulmonary veins different from the blood in the other arteries veins? B. Describe one SIMILARITY and one STRUCTURAL DIFFERENCE between AORTA and VENA CAVA 2- Kathleen decided to donate blood to the Canadian Red Cross. After donating blood, her blood pressure reading was 140 mm Hg / 95 mm Hg. Is this an example of hypotension OR hypertension? What are TWO possible side effects Kathleen may experience? EXPLAIN why she may experience themThe victim sustained a single stab wound to the left chest in the mid axillary line, just below the level of the nipple. The pointed weapon passes through the left lung and lodges to the heart. He was transported to our emergency department of CVMC. He was noted to be bleeding but eventually stopped. Though the bleeding stopped, he was observed to have low blood pressure and an increase heart rate. Upon blood transfusion his blood pressure increases and his heart rate lowered. a. Suggest an explanation for the following observation in his blood pressure and heart rate during bleeding and after blood transfusion.Cardiovascular and respiratory functions are highly integrated. We have already spent some time discussing how cardiac pathologies can lead to pulmonary oedema. Now let's take that to the next step in considering the following questions. Consider what effects pulmonary oedema will have on circulating blood gasses. How will this affect systemic arterioles, how will that impact TPR, and how the body will compensate for this change. (Select three answers). Systemic arterioles will dilate Systemic arterioles will constrict OTPR will increase OTPR will decrease O The autonomic nervous system will increase cardiac output O The autonomic nervous system will decrease cardiac output
- for its oxygen then it may die, forming rct. The severity of this condition depends on the precise location of the occlusion, which downstream tissues are involved, and how large an area of tissue dies. Use Figure 4.9 as a reference and list the flow of blood through both circuits in order, beginnng with the right atrium (don't forget to include the heart valves). 1. If an embolus breaks off in a systemic vein in the leg, it would be able to pass through: It would occlude: 2. If an embolus formed in the left ventricle, it would be able to pass through: 3. It would occlude: 4.Identify the function of the following terms IN THE CARDIAC CELL. (1-2 sentences only). Please use a credible source when answering. 1. Sacromere 2.

Pulmonary arteries ii. Pulmonary semilunar valve iii. Pulmonary trunk iv. Right atrium v. Right ventricle vi. Tricuspid valve vii. Vena cava O i, ii, i, iv, v, vi, vii O vii, iv, vi, v, ii, iii, i iii, iv, v, i, ii, vi, vii O i, ii, i, iv, vii, v, vi O v, vi, vii, i, ii, ii, ivWhile assisting the circulator during outpatient surgery under local anesthesia, you are asked to take the patient’s vital signs for the duration of the case. Explain the following: 1. You do not know what the patient’s normal vital signs are. Do you need to know this in order to carry out this role? 2. You cannot find an available digital blood pressure apparatus so you must use a stethoscope and manual sphygmomanometer. Is this important to the documentation?
- Match the descriptions with the correct heart chamber. contains high oxygenated blood which as just returned from the lungs contains low oxygenated blood which as just returned from the body contains high oxygenated blood that is being pumped out into the systemic circuit contains low oxygenated blood that is being pumped out into the pulmonary circuit pulmonary veins are attached to this chamber the pulmonary trunk is attached to this chamber the aorta is attached to this chamber the vena cavas are attached to this chamber houses the papillary muscles and the chordae tendinaea that are attached to the mitral valve houses the papillary muscles and the chordae tendinaea that are attached to the tricuspid valve blood leaving this chamber must travel thorough the bicuspid valve blood leaving this chamber must travel thorough the right atrioventricular valve blood…JOHN, AGE 24, IS INVOLVED IN AN AUTOMOBILE ACCIDENT. Ken, a paramedic, arrives on the scene and does emergency first aid. John has multiple lacerations on his hand and arms; the laceration on his right arm is bleeding profusely. Ken applies a pressure bandage and notes that John’s blood pressure is 90/60. Ken starts an intravenous line and transports John to the hospital. The ER doctor examines John and notes he also has contusions near his liver. The doctor has the med tech draw blood for a CBC and to type and crossmatch for blood. A severe loss of blood may lead to what condition? Name the blood components and their function. Why is the ER doctor concerned about possible liver damage? How does liver damage relate to the blood?1. Mr. Garcia had a myocardial infarction. Explain what happened to his heart muscle and vascular system. What is a STEMII? 2. Mr. Garcia's chest pain resolved after two sublingual NTF at 3-minute intervals and 2 mg of IV morphine. In the cardiac catheterization lab he was "found to have a totally occluded distal right coronary artery and a 70% occlusion in the left circumflex coronary artery. The left anterior descending artery was patent. Angioplasty of the distal right coronary artery resulted in a patent infarct- related artery with near normal flow. A stent was left in place to stabilize the patient and limit infarct size. Left ventricular ejection fraction was normal at 42%, and a posterobasilar scar was present with hypokinesis." a. Explain angioplasty and stent placement. Define occluded occlusion. b. What is the purpose of this medical procedure?
