Question 34  In COPD, hypoxemia may give rise to a condition known as polycythemia. What is polycythemia? Question 34 options: An increase in the number of circulating erythrocytes An increase in the number of circulating leukocytes An decrease in the number of circulating erythrocytes An decrease in the number of circulating leukocytes

Question 2 سلام 3 A 58-year-old man comes into your emergency room with difficulty breathing. He also reports some left side chest pain and points to the inferior portion of his ribs. You listen to his lung sounds and there seems to be reduced breath sounds in the inferior half of his left pleural cavity. Both PA and lateral chest films confirm what is likely fluid in the inferior 1/3 of the left pleural space. There were no obvious rib fractures. You wish to determine the nature of the fluid accumulating in the left pleural cavity, since that will dictate the appropriate treatment. What structures will your 19 g needle penetrate as you pass from skin to fluid at the midaxillary line below the ninth rib? E Answer saved Marked out of 1.00 Select one: O a. Skin, endothoracic fascia, parietal pleura, external intercostal muscle, internal intercostal muscle, innermost intercostal muscle, subcutaneous tissue O b. 4 Skin, subcutaneous tissue, external intercostal muscle, endothoracic fascia,…

Question 40 Korotkoff sounds are good because they indicate: O A. Regurgitation from the ventricle into the atrium through a faulty mitral valve. OB. Backflow through the tricuspid valve. O C. Turbulence in a malformed aortic arch. OD. All of the above. OE. None of the above. BAROSS

Question 17 The primary signal detected by the peripheral chemoreceptors is the O A. increase in P02, opening B. decrease in Po2, closing O C. increase in PO2, closing D. decrease in PCO2, opening OE. None of the above and of potassium channels that depolarize the Glomus cells.

Question 36  In COPD, hypoxemia may promote a compensatory increase in RBC production. What organ is responsible for detecting hypoxemia and releasing erythropoietin to stimulate RBC production? Question 36 options: Liver Red bone marrow Kidneys Peripheral chemoreceptors

Question 30 The major storage vessels for blood volume are: A. The Veins. OB. The Aorta. O C. The Capillaries. OD. The Arterioles. O E. The Ductus Arteriosus.

QUESTION 38 Phase C of the ventricular action potential is due to which of the following? B -50 A -100 0.15 0.30 Time (s) Na* influx through F-type pacemaker channels Na* influx through voltage-gated channels Ca2+ influx O k* influx through voltage-gated channels Membrane potential (mV)

Question 12 0/1 pts A patient with a hemothorax and hemoglobin of 8 mg/dL is to have an autotransfusion of chest tube drainage. Which of the following would be a contraindication? You Answered A low hemoglobin level. Correct Answer An autotransfusion system (ATS) bag used for collection of chest tube drainage. Collected blood in the chest drain for 8 hours. Chest tube drainage collecting at a rate of 100 mL/hr. Collected blood never remains in the chest drain or ATS blood bag for more than 6 hours before autotransfusion. A low hemoglobin level is an indication for need of a blood transfusion or autotransfusion of chest tube drainage. Blood loss of 50 to 100 mL/hr through a chest tube indicates active bleeding and is an indication for reinfusion of chest tube drainage. An ATS bag should be used for collection of chest tube drainage because it contains a filter to remove extraneous materials and microemboli.

QUESTION 3 Arterioles are composed of Endothelial cells and smooth muscle only Endothelial cells, elastic tissue, and fibrous tissue only Endothelial cells, elastic tissue, and smooth muscle only Endothelial cells, elastic tissue, smooth muscle, and fibrous tissue Elastic tissue and smooth muscle only

QUESTION 10 A 48-year-old female patient has breast carcinoma and presents to the hospital outpatient unit complaining of low energy. The physician orders hemoglobin and hemocrit counts, which were performed. After evaluation, it is determined the patient has anemia in neoplastic disease. The physician orders 3 units of packed red blood cells, which are transfused on the unit. Which coding is best for the blood products? (See the HCPCS options below.) HCPCS Code Descriptor P9010 Whole blood for transfusion, per unit P9021 Red blood cells for transfusion, per unit P9060 Fresh frozen plasma for transfusion, per unit, donor retested P9615 Catheterization for collection of specimen P9045 Infusion, albumin, 5%, 250 ml     A. P9021   B. P9021 X 3   C. P9045, P9060   D. P9010 X 3, P9615
