1-According to Helmenstine (2018), an independent variable is the variable that is changed or controlled in a scientific experiment to test the effects on the dependent variable & a dependent variable is the variable being tested and measured in a scientific experiment. For my project on fall prevention in the LTC setting, the independent variables will be; the type of medication given to patients, environment that the patients live, physical exercise, level of stress and body strength of the patients. Their age, gender,fall prevention measures during handoff and not allowing patients to dangle on the edge of the bed, use of sitters. The dependent variables would be the fall rates for the month of June and July and staff knowledge on fall prevention,the condition of patients after receiving anti-psychotic medication, the nature of body strength of patients and patient satisfaction . I am measuring the amount of falls and knowledge gained since they depend on the new measures in place. It is important to pay attention to both of these variables to make sure they are realistic and achievable. Knowing results helps me determine if my solutions are effective.

2-Independent variable is the implementation of the new SBAR trauma transfer audit/form. The subjective feedback from staff and the statistical patient outcomes would be the dependent variables. It is important to look at the results of the new plan and to see what is proven effective and what is not. It could also be beneficial to do a study before implementation to have nurses rate the communication on a scale 1-5 with recieving and transferring facilities and then one after implementation to look at the effectiveness of the new SBAR trauma transfer audit/form.

 

 

3-The independent and dependent variables may be viewed in terms of cause and effect. If the independent variable is changed, then an effect is seen in the dependent variable. Remember, the values of both variables may change in an experiment and are recorded. The difference is that the value of the independent variable is controlled by the experimenter, while the value of the dependent variable only changes in response to the independent variable.

This helped me better understand when looking at more of a cause and effect relationship. So, are you comparing the use of xarelto in stroke patients in contrast to those that don’t use xarelto?

Introduction
Click on the following links to view argument examples:

Link: Deductive Argument Example  

Claim: It is wrong for parents to allow children to watch violent movies

Analysis: My argument is deductive. My first premise is the broad general principle that children daily face examples of violence in the real world. My next premise is that watching violent movies helps children to think about how to deal with violent behavior. My conclusion is that watching violent movies is okay for kids. This argument has indicator words “if” and “then” so it is truth-functional. It would be stated this way: If children face violence daily then they need to think about how to deal with it. Violent movies help them to think about violence and how to deal with it. Therefore, it is okay for children to watch violent movies.

Instructions
Read the following argument examples in this activity.

Argument 1
Dick and Jane have insured their house and cars with Farmer’s Mutual for 10 years. During this time, they filed only one claim for $500, and the premiums have risen 100%. Two weeks ago, while backing out of the garage, Jane damaged the right fender. They didn’t fix it, and yesterday, while Jane was parked at the supermarket, someone hit the right side of the car, damaging everything but the right fender. When Jane checks the insurance policy, she discovers that while the supermarket accident is covered, the damaged right fender is not.

Jane says, “Let’s claim that all the damage happened at the supermarket. It’s only fair. The insurance company has made thousands of dollars from our premiums alone, not to mention all the other people they insure, so they’ll hardly miss the few thousands that their repairs will cost. Many of their friends have done the same – included items that were not part of actual collision damage. It’s unlikely that they we will be discovered, because the fender could easily have been damaged in the collision.”

Argument 2
In a world where medical resources are in ever-shorter supply, allocation of those resources is becoming an issue. Critical care units (ICU) put heavy demand on hospital resources. Adult medical intensive care units (MICU’s) are often occupied by elderly patients in the final stages of chronic illnesses. Neonatal ICU’s, however, are reserved for premature infants that need critical care in the first few days of life. Surveys of mortality rates in relation to amount of care for both units show that on a cost/benefit basis, outcomes for NICU patients are statistically better than those for MICU patients. Since hospitals should prioritize outcomes, it is clear that resources should be allocated more heavily to the NICU.

Using the examples in the introduction of this activity, address the following:

1. Briefly analyze each argument as follows: 
   • State the issue and the conclusion.
   • For each argument, analyze the argument: 
     • State if it is deductive or inductive.
     • Explain how the argument follows the form of an inductive or deductive argument.
   • Reference words, phrases, the structure of the argument, or any other facts or observations you believe support your claim.
2. Diagram the argument.
