Case Study 1: A 55-year-old COPD patient is admitted to the hospital with acute hypoxemia. The physician orders oxygen therapy to maintain SpO₂ between 88-92%. Which oxygen delivery device would you choose, and why? Include the recommended flow rate and FiO₂. Case Study 2: A 70-year-old patient with pneumonia and severe hypoxemia requires a FiO₂ of 60% to stabilize oxygen saturation. Which device is most appropriate, and what is the flow rate needed to achieve this? Case Study 3: A post-operative 50-year-old female is recovering from abdominal surgery. She complains of mild shortness of breath; her SpO₂ is 92% on room air. What oxygen device would you recommend, and at what flow rate? Case Study 4: A 35-year-old patient with carbon monoxide poisoning presents to the emergency room. His SpO₂ appears normal, but the physician insists on aggressive oxygen therapy. Which oxygen device is the most appropriate, and what is the expected FiO₂?

Would an appreciation of the yuan relative to the U.S. dollar be good news or bad news for U.S. firms such as Apple and McDonald's that have stores or restaurants in China? Briefly explain. A. Bad news, because sales in China are now worth less when converted to U.S. dollars. B. Bad news, because goods produced by Chinese competitors become less expensive. C. Good news, because they will earn more dollars when they convert an appreciated yuan into U.S. dollars. D. Good news, because the purchasing power of American consumers increases.

The implications of the client with AIDS visiting his friend who has the flu are significant. The client with AIDS has a compromised immune system, making him more susceptible to infections and illnesses. Being in close contact with someone who has the flu increases the risk of the client with AIDS contracting the flu, which could lead to serious complications and worsen his condition. It is important to advise the client against visiting his friend and to take precautions to protect his health.

P8.008 A beam is subjected to equal 18.2 kip-ft bending moments. Assume $t_1=t_2=t_w=2$ in., $d=17$ in., $b_1=5$ in., and $b_2=8$ in. The cross-sectional dimensions of the beam are illustrated. Determine: (a) the distance $\bar{y}$ to the centroid (measured from the bottom), the moment of inertia $I_z$ about the $z$ axis, and the controlling section modulus $S_z$ about the $z$ axis. (b) the bending stress $\sigma_H$ at point H (positive if tension, negative if compression). (c) the bending stress $\sigma_K$ at point K (positive if tension, negative if compression). (d) the maximum bending stress $\sigma_{max}$ produced in the cross section (positive if tension, negative if compression). Answers: (a) $\bar{y} = \underline{\qquad}$ in., $I_z = \underline{\qquad}$ in.$^4$, $S_z = \underline{\qquad}$ in.$^3$. (b) $\sigma_H = \underline{\qquad}$ psi. (c) $\sigma_K = \underline{\qquad}$ psi. (d) $\sigma_{max} = \underline{\qquad}$ psi.

6. [20 points] Let A be an array of $n$ numbers. Consider the problem of finding the maximum sum of any contiguous subarray. For example, if the items of A are -3, 2, 4, -5, 3, 2, -1, 4, the contiguous array with the maximum sum is 2, 4, -5, 3, 2, -1, 4; If the items of A are -5, 3, -2, 4, 6, -8, 1, -3, 5 then the answer is 3, -2, 4, 6. There are at four three known algorithms for this problem: (a) An exhaustive algorithm which takes $O(n^3)$ time. (b) A slightly more intelligent algorithm which takes $O(n^2)$ time. (c) A rather clever divide and conquer algorithm, which takes $O(n \log n)$ time. (d) A sophisticated dynamic programming algorithm which takes $O(n)$ time. Describe an algorithm for this problem, the fastest one you can find.
