A community health nurse is providing teaching to a client who is being enrolled in a randomized controlled trial. Which of the following statements by the client indicates an understanding of the teaching?
"I will not know if I am going to be in the intervention or control group."
"The study will last for 10 years. You will contact me annually for an interview and blood work."
"You'll need to find other participants like me but who do not have this disease."
"The survey will take an hour to complete and then I'll be done."
The Correct Answer is A
Choice A: "I Will Not Know if I Am Going to Be in the Intervention or Control Group."
This statement indicates an understanding of the concept of blinding in a randomized controlled trial (RCT). In an RCT, participants are randomly assigned to either the intervention group or the control group, and they are often blinded to which group they are in to prevent bias. This helps ensure the validity and reliability of the study results.
Choice B: "The Study Will Last for 10 Years. You Will Contact Me Annually for an Interview and Blood Work."
While this statement may describe the duration and follow-up procedures of some studies, it does not specifically indicate an understanding of the key aspects of a randomized controlled trial, such as randomization and blinding. The focus here is on the logistics rather than the methodology of the RCT.
Choice C: "You'll Need to Find Other Participants Like Me but Who Do Not Have This Disease."
This statement suggests a misunderstanding of the typical participant selection process for an RCT. In many RCTs, especially those testing new treatments, participants are selected based on having the condition being studied. The comparison is usually between those receiving the intervention and those receiving a placebo or standard treatment, not between those with and without the disease.
Choice D: "The Survey Will Take an Hour to Complete and Then I'll Be Done."
This statement indicates a misunderstanding of the nature of participation in an RCT. RCTs often involve multiple assessments, follow-ups, and possibly interventions over a period of time. A single survey is unlikely to encompass the full scope of participation in an RCT.

Correct Answer is B
Explanation
Choice A: Incidence is a Measure of Mortality
This statement is incorrect. Incidence refers to the number of new cases of a disease that occur in a specified population during a defined period. It measures the risk of developing the disease, not the number of deaths. Mortality rates, on the other hand, measure the number of deaths due to a disease in a population.
Choice B: Incidence Includes Only People at Risk for the Disease
This statement is correct. The incidence rate is calculated by dividing the number of new cases of a disease by the number of people at risk for the disease in the population during a specified period. This measure helps to understand the likelihood of developing the disease among those who are susceptible.
Choice C: The Denominator for the Incidence Rate Calculation is for the Entire Population
This statement is incorrect. The denominator for the incidence rate calculation should include only those individuals who are at risk of developing the disease, not the entire population. Including the entire population would inaccurately represent the risk, as it would include individuals who cannot develop the disease (e.g., men in the case of breast cancer).
Choice D: New Cases are Not Considered When Calculating an Incidence Rate
This statement is incorrect. The incidence rate specifically measures the number of new cases of a disease that occur in a population during a specified period. Therefore, new cases are a critical component of the incidence rate calculation.
Correct Answer is D
Explanation
Choice A reason: "Although I live in the country, my neighbor takes me shopping each week. It takes about 10 minutes for us to drive to the nearest grocery store."
This statement indicates that the client has access to a grocery store within a reasonable driving distance, even though they rely on a neighbor for transportation. While this situation may present some challenges, it does not fit the definition of a food desert, which is characterized by limited access to affordable and nutritious food.
Choice B reason: "Sometimes I get food from the Salvation Army food pantry that is about a half a mile from my house."
This statement suggests that the client has access to a food pantry relatively close to their home. While relying on food pantries can indicate food insecurity, it does not necessarily mean the client lives in a food desert. Food deserts are defined by the lack of access to grocery stores that provide fresh and nutritious food.
Choice C reason: "I am able to walk to a grocery store that is 5 blocks away from my apartment."
This statement indicates that the client has convenient access to a grocery store within walking distance. This accessibility does not align with the characteristics of a food desert, where residents typically have to travel long distances to reach a grocery store.
Choice D reason: "I cannot always afford ride-share services to get to the nearest store, which is 30 minutes away from where I live."
This statement fits the definition of a food desert. The client has to travel a significant distance to reach the nearest grocery store and faces financial barriers to accessing transportation. This limited access to grocery stores that provide fresh and nutritious food is a key characteristic of food deserts.
