“Risk pooling effect” results from the fact that grouping or pooling multiple (random) demands induces less accurate forecasts.

Read the case scenario carefully. Then, answer the following questions based on your clinical judgment and understanding of nursing care for a client with multiple chronic health conditions. Client: James Holloway  Age: 76  Medical History: Type 2 Diabetes, Congestive Heart Failure, Hypertension, Stroke in 2021  Admission: Post-operative Day 2 following bowel obstruction surgery  Clinical Notes:  Foley catheter in place since surgery  Central line (right internal jugular) for antibiotics and fluids  Bedrest with bathroom privileges  NPO, awaiting bowel sounds  Wound is dry and intact  No documented bowel movement yet  Question:  Which of the following is the most appropriate nursing intervention to prevent a catheter-associated urinary tract infection (CAUTI) in Mr. Holloway? 

Problem #3 (continued) Design suitable deep-groove ball bearings for a 10% failure rate to support the load shown below for at least 100×106 cycles at 1800 rpm. Take the shaft diameter to be 40 mm and the reaction force on the left bearing to be Rleft = 6275 N and the reaction force on the right bearing to be Rright = 7525 N. (b) Which bearing would you select for the right bearing? Show your work.    

Problem #4 (continued) A bearing with a diameter of 30 mm and length of 25 mm has a diametral clearance of cd = 45 μm. Consider lubrication with an oil that has an absolute viscosity of η=16 cP (recall that 1 cP = 10-3 Pa⋅s). Utilize a design load of P = 7.2 kN, a rotational speed of 1500 rpm, and an Ocvirk number of ON = 30 for the bearing.   (b) What is the stationary torque, Ts? Express your answer in N-m.

Problem #3(a) Design suitable deep-groove ball bearings for a 10% failure rate to support the load shown below for at least 100×106 cycles at 1800 rpm. Take the shaft diameter to be 40 mm and the reaction force on the left bearing to be Rleft = 6275 N and the reaction force on the right bearing to be Rright = 7525 N. (a) Which bearing would you select for the left bearing? Show your work.    

Which of the following would be a logical follow-up question based on the data presented below?  

15 extra minutes has been provided to allow you to upload your work for the exam to facilitate partial credit. If you have trouble uploading your work directly to the exam, you can email Dr. Diaz a scanned copy of your work (nancyd1@usf.edu) immediately following the submission of your exam.

Many neurological conditions can be described as “synaptopathies,” reflecting their dependance on dysfunction at the level of the synapse. List three or more potential mechanisms whereby a synapse might be rendered dysfunctional (aka, how do you break a synapse?).

What paraphilia is relatively common, and involves urges or fantasies about exposing one’s genitals to strangers in order to cause shock in the observer.

Which individual exhibits a paraphilia?
