Bob has been active all of his life. He played soccer from elementary school all the way through college. He even played on a community team but now at age 45, he’s been diagnosed with high blood pressure (hypertension). At times he ate too much junk food and occasionally drank too much alcohol but he couldn’t get around the fact that the men in his family all had high blood pressure. Dr. Miller, Bob’s primary care physician, had to prescribe two different antihypertensive medications in order to get his blood pressure under control. She also recommended Bob continue his regular soccer workouts but suggested a low-salt diet and more modest alcohol intake. Bob heeded Dr. Miller’s recommendations. His father and his 2 uncles had hypertension at a young ages, and all 3 men ended up on dialysis before dying from complications of kidney failure.Bob began the recommended lifestyle changes at age 45 and even started running regularly to keep his blood pressure under control. Now, 10 years later, he was a marathoner and participated in local marathons, competing with, and outrunning many his own age. However, Bob noticed that during the past several months, he’d experienced more fatigue than normal and some dehydration symptoms after his long runs. After consulting with Dr. Miller, Bob sought the help of Ty, an exercise physiologist, to help him maintain his exercise regime and his health without feeling “old”.Ty worked with Dr. Miller to make sure that Bob was monitored closely since he was still taking his anti-hypertensive medications. Ty suggested a urinalysis to assess Bob’s physical condition before, during and after his workouts. Bob dutifully supplied urine samples to Dr. Miller for evaluation as Ty recommended. Ty explained that Bob’s dehydration symptoms were more difficulty to evaluate since the medication Bob took to control his high blood pressure could affect his renal status or physiologic functioning.Dr. Miller logged the following results of Bob’s urinalysis immediately after, and six hours after, a rigorous 2-hour run.

Based on the urine color and specific gravity, Ty assessed Bob’s hydration status at the three different urine collection times. Explain what you believe to be Bob’s hydration status before Bob began his workout, immediately after his work and 6-hours after his workout.

Antidiuretic hormone (ADH) plays a large part in regulating the formation of concentrated or dilute urine. During Bob’s long runs, his ADH secretion would change based on how much he perspired. Explain why ADH secretions would fluctuate during Bob’s long runs.

Ty noted the color changes of Bob’s urine before, immediately after and 6-hours after his workouts. What do the color changes of Bob’s urine indicate?

Ty also noted that Bob’s specific gravity changed with each urine collection. Explain how Bob’s urine color/concentration compare to the urine specific gravity at the same time?

Sheila Goodman recently received her MBA from the Harvard Business School. She has joined the family business, Goodman Software Products Inc., as Vice-President of Finance. She believes in adjusting projects for risk. Her father is somewhat skeptical but agrees to go along with her. Her approach is somewhat different than the risk-adjusted discount rate approach, but achieves the same objective. She suggests that the inflows for each year of a project be adjusted downward for lack of certainty and then be discounted back at a risk-free rate. The theory is that the adjustment penalty makes the inflows the equivalent of riskless inflows, and therefore a risk-free rate is justified.

A table showing the possible coefficient of variation for an inflow and the associated adjustment factor is shown next:
  

Assume a $125,000 project provides the following inflows with the associated coefficients of variation for each year.
  

  
Use Appendix B for an approximate answer but calculate your final answer using the formula and financial calculator methods.

a. Fill in the table below: (Do not round intermediate calculations. Round "Adjustment Factor" answers to 2 decimal places and other answers to the nearest whole dollar.)
  

  
b-1. If the risk-free rate is 6 percent, compute the net present value of the adjusted inflows. (Negative amount should be indicated by a minus sign. Do not round intermediate calculations and round your answer to 2 decimal places.)
  

CASE STUDY Patient Profile Mahmoud is a 26-year-old secondary school teacher. He seeks the advice of his health care provider because of changes in his appearance over the past year. Subjective Data • Reports weight gain (particularly through his midsection), easy bruising, and edema of his feet, lower legs, and hands • Has been having increasing weakness and insomnia Objective Data • Physical examination: BP 150/110; 2+ edema of lower extremities; purplish striae on abdomen; thin extremities with thin, friable skin; severe acne of the face and neck • Blood analysis: Glucose 167 mg/dL (9.3 mmol/L); white blood cell (WBC) count 13,600/μL; lymphocytes 12%; red blood cell (RBC) count 6.6 × 106/μL; K+ 3.2 mEq/L (3.2 mmol/L) Discussion Questions (answer the following questions): 1. Discuss the probable causes of the alterations in Mahmoud’s laboratory results. 2. Explain the pathophysiology of Cushing syndrome. 3. What diagnostic testing would identify the cause of Mahmoud’s Cushing syndrome? 4. What is the usual treatment of Cushing syndrome? 5. What is meant by a “medical adrenalectomy”? 6.

Twenty students from Sherman High School were accepted at Wallaby University. Of those students, eight were offered military scholarships and 12 were not. Mr. Dory believes Wallaby University may be accepting students with lower SAT scores if they have a military scholarship. The newly accepted student SAT scores are shown here.

Military scholarship: 850, 925, 980, 1080, 1200, 1220, 1240, 1300
No military scholarship: 820, 850, 980, 1010, 1020, 1080, 1100, 1120, 1120, 1200, 1220, 1330

Part A: Do these data provide convincing evidence of a difference in SAT scores between students with and without a military scholarship? Carry out an appropriate test at the α = 0.05 significance level. (5 points)

Part B: Create and interpret a 95% confidence interval for the difference in SAT scores between students with and without a military scholarship.

The Gourmand Cooking School runs short cooking courses at its small campus. Management has identified two cost drivers it uses in its budgeting and performance reports—the number of courses and the total number of students. For example, the school might run two courses in a month and have a total of 60 students enrolled in those two courses. Data concerning the company’s cost formulas appear below:

For example, administrative expenses should be $4,000 per month plus $45 per course plus $4 per student. The company’s sales should average $890 per student.

The company planned to run four courses with a total of 60 students; however, it actually ran four courses with a total of only 50 students. The actual operating results for September appear below:

Required:

Prepare a flexible budget performance report that shows both revenue and spending variances and activity variances for September. (Indicate the effect of each variance by selecting "F" for favorable, "U" for unfavorable, and "None" for no effect (i.e., zero variance). Input all amounts as positive values.)

Complaint:

Five children from the same school presented with abdominal pain and diarrhea (streaked with blood) over a period of 3 days. Upon investigation it was found that those children had recently been in birthday party. Fecal specimen was collected and sent to microbiology lab. Lab report showed presence of pus cells on direct microscopy and non motile bacteria on motility test.

Clinical History: The children are usually healthy. They take no regular medications

a. What is the possible clinical diagnosis?

b. What is the etiological agent and its natural reservoir?

c. How could these infected children be treated?

d. Identify parasitic organism could resemble the same clinical feature of this infection and what laboratory test is used to diagnose it?

e. Identify a virus cause diarrhea with possibility of developing flaccid paralysis? What are the best samples for diagnosis of this virus? What immunological test can be used to confirm this viral infection? Is any prophylaxis available for this virus? If so, explain!
