Answer to Question 1

Correct Answer: 1

The sample is the most accessible group of the population. For this research question the most accessible group of the population would be patients with diabetes. Patients may have foot ulcers but not have diabetes. There is no reason for the nurse to study patients without foot ulcers.

Answer to Question 2

Correct Answer: 1

The dependent variable is the presumed effect from the manipulation of the independent variable. In other words, the dependent variable is often the outcome of interest. The conceptual variable defines the qualities of the variable of interest. The operational variable describes how a variable is measured. The independent variable is the reason for the change in the outcome.
