Answer:

To study the effect of group cognitive behavioral therapy for post-partum depression, Van Lieshort and colleagues (2022) recruited participants through a convenience sampling plan using social media or helathcare provder referrals.  What is a key disadvantage of convenience sampling? 
  
Correct. Convenience sampling selects participants based on the ease of access to them.  Those who are easier to access and agree to participate may be different from those who are not easy to access.
  
  
  

Question 2

Question:

You are interested in determining if the length of stay in the urgent care clinic has changed from last year.  You EMR collects this data on all patients who present for care in the urgent care clinic. You have access to this data for all patients seen in the last 2 years.  You decide to focus on the months of October, November, and December as these are the months with the highest census.  You download the data from the EMR and utilize the computer to randomly select 250 patients from last year and 250 patients from this year. What type of sampling are you using?

Question 4

Question:

An investigator collected data on the confidence levels of nursing students following a cardiac arrest simulation. The data were collected with a self-report survey. What limitation would you expect the investigator related to data collection with a self-report survey?

Answer:

An investigator collected data on the confidence levels of nursing students following a cardiac arrest simulation. The data were collected with a self-report survey. What limitation would you expect the investigator related to data collection with a self-report survey? 
  
  
Correct. A major limitation of self-report surveys is the potential for response bias and inaccuracies. This can arise from participants' desire to appear socially desirable, memory inaccuracies, and their limited self-awareness, leading to responses that don't accurately reflect their experiences or behaviors.

Question 6

Question:

An investigator is interested in studying the relationship between vaping and lung disease.  Which research design is best suited for this study?
Group of answer choices

Answer:

An investigator is interested in studying the relationship between vaping and lung disease.  Which research design is best suited for this study?
  
  
  
Correct.  A correlational design is a non-experimental design used to identify and evaluate relationships between variables.  
  

Question 7

Question:

Which of the following components distinguishes an experimental design from a quasi-experimental design?
Group of answer choices

Answer:

Which of the following components distinguishes an experimental design from a quasi-experimental design?
  
Correct. The component that distinguishes an experimental design from a qusai-experimental design is randomization.  Experimental designs include randomization while quasi-experimental designs do not include randomization.
  
  
  

Question 8

Question:

An investigator is evaluating the effect of a keto diet on weight loss. How can the investigator control confounding characteristics between the experimental and control groups? 
  
Correct.  There are multiple ways to control extraneous or confounding variables in an experiment.  The best method is through randomization in the sample selection or group assignment.  Matching participants in the experimental group with those in the control group is another way to control confounding variables but it is a time-consuming process.  There are statistical methods that can be used to control confounding variables.
