An infant’s height at his one-year check-up provided a standardized (z) score that was -0.57. What does this score tell about how tall the infant was in relation to all other one year olds?

For a Poisson distribution, an interval of length 4.5 has μ = 10.8.   What value of μ would you use if you changed the interval length to 6.5? [a] Retype your answer. [b]  

A 50 – year old type 1 diabetic woman has developed an ulcer that penetrates into the fat on the plantar aspect of the left foot, under the ball of her big toe. She has foot swelling so pulses are not palpable, but she has good capillary refill in the toes. The ulcer is not painful and is not clinically infected. What is the next best step for this problem? 

Suppose that the number of bug reports arriving at an IT department of a software development company follows a Poisson distribution with an average of 6 reports over a 4-day period. Use the partial probability table below to answer the following questions. What is the probability that… x 0 .3679 .2231 .1353 .0498 .0183 .0111 .0025 .0009 0 1 .3679 .3347 .2707 .1494 .0733 .0500 .0149 .0064 .0003 2 .1839 .2510 .2707 .2240 .1465 .1125 .0446 .0223 .0015 3 .0613 .1255 .1804 .2240 .1954 .1687 .0892 .0521 .0053 4 .0153 .0471 .0902 .1680 .1954 .1898 .1339 .0912 .0139 5 .0031 .0141 .0361 .1008 .1563 .1708 .1606 .1277 .0293 6 .0005 .0035 .0120 .0504 .1042 .1281 .1606 .1490 .0513 7 .0001 .0008 .0034 .0216 .0595 .0824 .1377 .1490 .0769 8 0 .0001 .0009 .0081 .0298 .0463 .1033 .1304 .1009 9 0 0 .0002 .0027 .0132 .0232 .0688 .1014 .1177 10 0 0 0 .0008 .0053 .0104 .0413 .0710 .1236 … … … … … … … … … …   Use FOUR decimal places for your answers, since that is the number given in the table!

A 70 – year – old man presents with moderately limiting claudication.  He has diabetes, hyperlipidemia, and hypertension and is a current smoker.  Her is on an aspirin and beta-blocker.  The first most important step in his management is: 

When taking this exam, I will respect the honor code for this course. I will display academic integrity by not using unauthorized devices, unauthorized websites, unauthorized notes, unauthorized formula sheets, etc. I will refrain from discussing the exam and its questions with my peers until after the exam becomes reviewable.   I will NOT use a statistical calculator with built-in distributions, the internet, or excel to compute values for the various probability distributions on this test. I will either plug values into a formula from my provided formula sheet, use the normal table provided for this course, or use the t-table provided for this course to obtain these probabilities instead. The work on this exam is a reflection of what I personally am able to do at this specific moment in time.

A 55-year-old Caucasian female presents for further evaluation of painless cervical lymphadenopathy of six months duration.  She denies fevers, chills, night sweats, weight loss or other concerning systemic complaints.  She has no significant past medical history.  She is a lifelong nonsmoker and is on no medications.  Physical examination confirms diffuse bilateral cervical lymphadenopathy that is nontender and mobile.  She has no other pathologic lymph nodes on exam.  Abdominal examination reveals no organomegaly.  The following peripheral smear is available for your review: Question:  Based on the provided history and peripheral blood smear, what is the MOST LIKELY diagnosis?

1.       A 51 yo white male is being evaluated in the hospital for acute renal failure in the setting of recent heart catheterization (2 days ago) for heart failure.  Coronary angiogram revealed mild coronary artery disease- no intervention was undertaken.  Right heart pressures suggested fluid overload- pt has since been aggressively diuresed with I.V. furosemide. His laboratory trend:         2 days ago 1 day ago today creatinine 0.85 1.1 1.4 BUN 14 23 27 Sodium 137 135         133   Urinalysis is sent- It shows SG 1.015, no protein or blood, no LE or nitrates. There are hyaline casts.   Urine osmolarity is 410.  Urine sodium is 48.  Urine creatinine is 48. Urine urea is 400.   What is the likely cause of patient’s renal failure?
