Question Description

Choose one (1) clinical scenario above, and answer the following questions:

  1. What is evidence-based nursing practice and why is it important?
  2. What is the PICO process?
  3. Formulate a well defined clinical question that will yield the most relevant and best evidence.
  4. Describe the background of the question
  5. Present the question using PICOT format
  6. Indicate what will be the best study to answer the clinical question.

Scenarios:

#1 A nurse in the PACU is interested in ways to decrease the use of pain medication in post-op patients. She’s wondering if classical music or guided imagery might be efficacious.

#2 A 17-year-old African American woman, just diagnosed with hepatitis B, has been taking acetaminophen for headaches. Her mother has heard that acetaminophen can cause liver problems, and she asks you if her daughter should continue taking the drug for her headaches, considering her hep-b diagnosis.

#3 You are on a hospital committee exploring best practices in inpatient oncology nursing. The first question to come before the committee is, “how can we improve patients’ sleep quality and quantity without resorting to sleep medication?” The committee decides to explore relaxation techniques (e.g., massage; music), noise reduction, bed/pillow comfort, and ambient temperature changes. Your assignment is to find the best practices to reduce noise levels on the unit.

#4 A 53-year-old woman with rheumatoid arthritis wants to possibly change her medication to short-term low-dose corticosteroids instead of NSAIDS, which are upsetting her stomach. Will the corticosteroids be as effective?

#5 Jeff, a smoker of more than 30 years, has tried to quit unsuccessfully in the past. A friend of his recently quit with acupuncture. He wonders if he should try it.

Just follow the instructions!

Question Description

  1. SUMMARY
  1. Adjust the code we did in class to do a recursive binary search on a sorted array of Strings instead of integers.
  1. This lab will involve the following new features:
    1. Recursion
    2. Binary Search Algorithm
  1. DETAILS
  1. These instructions will be more bare than usual since the source code from class is being provided and I want you to think through all the changes you need to make.
  1. Set up your String array.
    1. Instead of having a “for” loop populating your array with random numbers, go ahead and make your array 10 in length and populate it in 10 lines of code that put a different string in each array slot, such as:

asWords[0] = “Frank”;

…

  1. Change all references to the array and any references pulling values from the array to String type instead of int type.
  1. Adjustment to binary search method.
    1. Besides figuring out which things have to now become String type, you need to compare the string values a bit different than the integers by using the “equals” and “compareTo” methods.
      1. Example for equals check:
        1. Instead of…
          1. iTarget == …
        2. It’s this…
          1. sTarget.equals(…)
      2. Example for greater than check:
        1. Instead of…
          1. iTarget > …
        2. It’s this…
          1. sTarget.compareTo(…) > 0
            1. The reason you are seeing if the comparison is greater than 0 is because the “compareTo” method returns a number greater than 0 if sTarget is greater than the string that’s passed in the parentheses. If it’s equal, it returns 0 (but that won’t happen because the equals comparison was in the first if statement). And if it’s less than, it returns a number less than 0.
  1. You can remove, comment out, or update the traditional search method at the bottom of the code. It’s up to you.

Question Description

Chapter 10 – Policymakers are tasked with making decisions on issues characterized as wicked problems because of controversies, unknown relationships between causes and consequences, and uncertain futures.

From this perspective, Moody and Gerrits (2015) think that it’s desired to get decisions mapped ahead of the possible outcomes prior to the actual decision-making because that would generate certainty in ambiguous situations. Looking closely at the Technological perceptions, technology is thought to revolve around humans. It reflects on questions of who drives technology.

Q1: Please identify and name a few of those questions discussed in this debate and provide a brief explanation around your thoughts?

  • identify and name five (5) of the few questions discussed in the debate
  • provide a short and clear narrative for each question identified to support your responses,
  • *************************************************************************************************************************************************************************************************************************

Chapter 10 – Policymakers are tasked with making decisions on issues characterized as wicked problems because of controversies, unknown relationships between causes and consequences, and (consequently) uncertain futures. From this perspective, it would be desirable to map the decisions and their possible outcomes prior to the actual decision making because that would generate certainty in ambiguous situations. Broadly speaking, this provides the motive for using computational modeling for policymaking as expressed in, e.g., policy informatics.

Q2: From this revelation, why is it more common to work with models “modded off-the-shelf” (MOTS) or even tailor-made models to suit specific questions and conditions?

  • identify and name the reason for why it’s more common to work with MOTS as indicated above?
  • provide a short and clear narrative to support your responses,

Please finish the following 2 question in this file.

Question Description

I need a complete process of solving problems.

You will create a design for an Ethernet network connecting four buildings in an industrial park. Hand in a picture showing your network. There will be a core switch in each building.

Building A is the headquarters building.

Building B is 85 meters south and 90 meters east of the headquarters building. A line will run directly from Building A to Building B.

Building C is 150 meters south of the headquarters building. A line will run directly from Building A to Building C.

Building D is 60 meters west of Building C. A line will run directly from Building C to Building D.

Computers in Building A need to communicate with computers in Building B at 600 Mbps.

Computers in Building A need to be able to communicate with computers in Building C at 1 Gbps.

Computers in Building A must communicate with computers in Building D at 500 Mbps.

Computers in Building C must communicate with computers in Building D at 750 Mbps.

  • Draw a picture of the situation.

b) Determine the traffic volume on each transmission line. Explain your answers.

First, show all of the traffic between pairs of sites:

Second, add up the traffic for each line.

c) Determine what standard to use for each transmission line. Explain your answers.

If the distance is more than 100 meters, use fiber; if it is 100 meters or less, select UTP.

Then, select the lowest-speed standard (including bonding) sufficient to handle the traffic.
