pharmacology grades

For those of you who don't routinely check your student emails, here's the latest from Mr. Scott....


Dear HS 3, N 3 Students:Beginning now, I will posting grades in the turnitin.com website rather than DocuShare. Each student’s grade will be anonymous and the gradebook will retain all of your scores. It is an improved way of record keeping for me as well as a better way of you tracking your performance in the class.In order for you to get your grades in this course, you will need to go to the turnitin.com website and open an account. Below are the instructions to do this.Go to the turnitin.com home page.In the upper right corner, you will see, “New Users.” Click on that.On the page that appears, click on “Student.”Under class ID, enter 2441659Under class enrollment password, enter pharmacologyComplete the remaining portion of the form and click on I agree—create profileOnce you are enrolled, you will be able to access the course, HS 3, N 3 Administration of Medication.I will not be developing the gradebook until students have enrolled. Please be patient, this may take some time. I hope to place your Exam II scores in the turnitin gradebook.Thanks for participating.Bruce Scott

N001...the final

The final is scheduled for october 16 at EMSTI from 0800-1200. It is comprehensive and worth 100 pts of the grade.

*50 pts-multiple choice (like what we usually have)
*25 pts-dosage calculations (application type calculations, not like pharm)
*25 pts-short answer response to case scenario

There will be a study guide available on Mrs. Semillo's DocuShare when it is ready.

test-taking tutorial

the test-taking tutorial is available in the nursing computer lab and is very helpful, this is an outline of the main points and makes more sense if you already looked at the tutorial.

*Parts of a Question
-case scenario: describes nursing problem
-stem: points forward to the answer

*Critical Elements
-issue: primary problem
-->answer must relate to the issue
-client: person of focus in stem
-->answer must relate to the client
-key words: important words in the question
-->points forward to the best option
-stem: asks to solve the problem in scenario presented
-->true response: answer will be a true statement
-->false response: answer will be a false statement
-distractors: distracts from answering the question correctly
-->label your options as true statements (+), false statements (-), and statements you are unsure of (?)

*Points to Remember
1) Identify the critical elements (issue, client, key words, and stem)
2) Restate the question to identify the issue
3) Rule out options containing new information
-remember...what is the best for the client?
-and...time is never a factor

*Test-Taking Strategies
Strategy 1: Global Response Options
-the general, comprehensive option is usually correct
-includes ideas from other "correct" options
Strategy 2: Eliminate Similar Distractors
-eliminate options saying nearly the same thing
Strategy 3: Similar Word Options
-options using similar words as the question are usually correct, but not always!

*Communication Questions: Always Identify the Client First
-communication tool: promotes therapeutic communication
-->includes being silent, offering self, showing empathy, focusing, restatement, validation/clarification, giving information, dealing with here and now
-communication blocks: do not promote therapeutic communication and can be eliminated
-->includes giving advice, showing approval/disapproval, cliches and false reassurance, requesting explanation, devalue feelings, being defensive, focus on inappropriate issues, putting concerns "on hold"

*Maslow's Hierarchy
-physiological needs first (airway, breathing, circulation), then safety


**What is the safest, most ideal, and within a nurse's scope of practice?
