A client arrives at the emergency department via EMS after falling from a horse and is unresponsive. The nurse notes that a cervical collar is in place. Which action should the nurse perform first?

After administration of IV lorazepam, the client’s seizure subsides, but respirations are shallow and O₂ saturation is 88%. Which action should the nurse take next?

A client with diabetic ketoacidosis (DKA) has a prescription for an insulin infusion at 0.1 units/kg/hr. The client weighs 155 lb (70.5 kg). The pharmacy has provided a premixed bag containing 100 units of regular insulin in 100 mL of normal saline. The primary nurse has programmed the infusion pump to deliver 10 mL/hr.What action should the charge nurse take next?

A client with diabetic ketoacidosis (DKA) was admitted to the intensive care unit 4 hours ago. The following laboratory results are available:Blood glucose level: 450 mg/dLSerum potassium level: 2.5 mEq/LSerum sodium level: 140 mEq/LUrine specific gravity: 1.025Total urine output (past 4 hours): 50 mLThe client has two IV lines infusing normal saline solution. The physician provides the following orders. Which provider order should the nurse question?

1) Be sure you open the quiz on your computer and have your camera on and make sure you are in a quiz taking setting. Apple electronics do not function on Final Exam.2) You must have your camera ON during the quiz or you will not receive credit. All answers to the Quiz are True.

Which of the following situations best illustrates the impact of competitive forces on a company’s strategic opportunities?

[Midterm Q3] It behooves us as scientists to honor our forebears.   a. Name the man responsible for inventing the field of experimental design. b. Name where he worked when he developed the factorial design and ANOVA. c. During which decade did he discover the basic experimental design principles?

[Midterm Q5] Why is it wise to partition experimental resources into a series of smaller experiments rather than conduct a single large experiment?  Can you give an example of why sequential experiments might be wise or prudent?

[Midterm Q11 A, B, C, D, E]  A nickel-titanium alloy is used to make components for jet turbine aircraft engines. Cracking is a potentially serious problem in the final part, as it can lead to losing an engine in flight. A test is run at the parts producer to determine the effects of three factors on cracks. The three factors are pouring temperature (A), titanium content (B), heat treatment method (C).  Three replicates of a 23 design are run, and the length of crack (in μm) induced in a sample coupon subjected to a standard test is measured. The data are in the attached file Midterm11a.dxpx a.Estimate the factor effects. Which effects are large? b.Use the analysis of variance to confirm your conclusions for part (a). c.Write down a regression model for predicting length of cracks based on the results of this experiment.  You may cut & paste from DX. d.Analyze the residuals. Are there any obvious problems? e.Based on the analysis of main effects and interaction plots, what levels of A, B, and C would you recommend using, assuming small cracks are best?  

[Midterm Q10 D, E, F] Same bone loss treatment problem as described in problem 10 – this time to analyze results. In this problem you will find attached a Design Expert file named Midterm10d.dxpx. Use Design Expert to analyze the data found in this file. Is there evidence to support a claim that PEMF usage affects bone density loss? If so, determine which specific treatments reduce bone loss. Record your response to this question here. In the ANOVA table the PEMF P value for the this data set is? P= 0.NNNN.    e. If you find any outliers, assume they are from data entry errors and set them aside. What is the ANOVA table PEMF value for the revised data set? P= 0.NNNN. Does setting apart the outliers change your conclusion from part d? f. Are there any other problems with violations of assumptions from residual analysis?
