Use the Nernst equation to calculate the cell potential for the following cell: Sc|Sc3+, 0.0010M||Sn2+, 1.0M|Sn Sc3++ 3e−⟶Sc   Eo= −2.09V Sn2++2e−⟶Sn    Eo=  −0.1375V To receive full credit (2 pts for answer and 2 pts for showing work), submit a picture of your work to the Final Exam Required Work & Partial Credit  assignment AFTER SUBMITTING COMPLETED FINAL

A key factor that affects the amount of scatter produced is:

The three primary factors influencing the intensity of scatter in the image-forming beam are:  

Factors that impact the visibility of detail include all of the following EXCEPT:

When changing your SID from 72” to 50”:

The factors that directly affect x-ray quality are:

A 29-year-old man is evaluated in the emergency department following a high-speed motor vehicle collision. He sustained multiple fractures and suffered significant blood loss. Temperature is 38.7°C (101.7°F), heart rate is 110/min, blood pressure is 85/50 mmHg, respiratory rate is 24/min, and oxygen saturation is 90% on room air. He receives 2 units of O-negative packed red blood cells. Two hours after the transfusion, he develops dyspnea, hypoxemia, and a non-productive cough. On examination, he appears anxious, tachypneic, and is using accessory muscles of respiration. There are no rashes. The trachea is midline. There is no jugular vein distension. Pulmonary auscultation reveals bilateral rales. There is no lower extremity edema. The patient is intubated and mechanically ventilated. PaO2/FiO2 is equal to 230. Chest X-ray is shown below. Which of the following is the most likely diagnosis?

An initial exposure is made using 800 mA, 0.02 sec, 16 mAs, 70 kVp, 58” SID, 4 “ OID, 5:1 grid ratio, 0.2 mm focal spot, 3.0 mm of filtration, and a 14 x 17 in field size. If the technologist changes the exposure time to 0.04 sec for a second exposure without changing any other factors, what differences would you expect to see in the second exposure?1. increased IR exposure2. decreased IR exposure3. increased contrast4. decreased contrast5. increased spatial resolution6. decreased spatial resolution7. increased distortion8. decreased distortion

A 58-year-old man is undergoing a red blood cell transfusion. Thirty minutes into the transfusion, he suddenly develops dyspnea, cough, and chest tightness. Past medical history is significant for hypertension and type 2 diabetes mellitus. Temperature is 38.7°C (101.7°F), heart rate is 110/min, respiratory rate is 28/min, blood pressure is 90/50 mmHg, and oxygen saturation is 88% on room air. On physical examination, he appears anxious and tachypneic. There is no rash or urticaria. Auscultation of the lungs reveals bilateral rales without wheezing. There is no lower extremity edema. Which of the following is the best next step in management?  

Now you are going to create a scenario analysis in your Echolab solution, so first copy your initial valuation to a new sheet and name it “Scenario”. You will create a table to model the following scenarios to the right of the model inputs: United States:  Sales Year 1 of $28 million, Variable Costs of 27.5%, initial Revenue Growth of 14%, and SG&A of $500,000, $550,000 and $600,000  Slovakia:  Sales year 1 of $25 million, Variable Costs of 25%, Initial Revenue Growth of 15%, and SG&A of $300,000, $325,000, and $350,000 France:  Sales year 1 of $32 million, Variable Costs of 30%, Initial Revenue Growth of 12%, and SG&A of $400,000, $450,000, and $500,000 Make sure to have a dropdown menu for your audience to choose the different scenarios.  You should use each of the following at least once each in your model:  match, index, offset, and lookup. Which scenario would you tell the company to choose?
