What is the population of interest for a study that includes this sample?
"Registered nurses who completed orientation within 6 months of graduation from nursing school and were current employees at the study hospital were invited to participate in the study."
RN employees who were hired 0 to 6 months after graduating and were still employed at the hospital when the study began.
All RNs who were hired by the hospital within 6 months of graduation from nursing school.
RN employees at the study hospital who were hired, completed orientation, and later agreed to participate in the study.
All RNs in the city where the hospital was located who graduated within the past 6 months.
The Correct Answer is A
A. This choice accurately describes the population of interest as it specifies RN employees who completed orientation within 6 months of graduation and were still employed at the study hospital at the time of the study.
B. This choice includes all RNs hired by the hospital within 6 months of graduation, which may include individuals who did not complete orientation within that timeframe or who were no longer employed at the hospital at the time of the study.
C. This choice narrows the population to RN employees at the study hospital who agreed to participate in the study, omitting those who did not participate.
D. This choice expands the population beyond the specific hospital mentioned in the study to all RNs in the city who graduated within the past 6 months, which may include individuals not relevant to the study.

Correct Answer is D
Explanation
A. External validity refers to the generalizability of study findings to the broader population, while this scenario involves a potential threat to the internal validity of the study.
B. Selection bias occurs when the sample is not representative of the population, which is not directly applicable to this scenario.
C. There is no indication of a measurement error in this scenario, and a new sample is not necessary. The issue relates more to the internal validity of the study.
D. The introduction of a new walker represents an external event that could potentially confound the study results, posing a threat to the internal validity by introducing a factor outside of those examined that may affect the outcome.
Correct Answer is D
Explanation
A. Longitudinal studies involve observing the same subjects over an extended period to assess changes over time. The study described involves comparing two groups (control and experimental) at one point in time, rather than observing changes in the same subjects over time.
B. Quasi-experimental studies resemble experimental designs but lack random assignment to groups or lack control over certain variables. The study described involves random assignment to groups (control and experimental), making it an experimental design rather than quasi-experimental.
C. Descriptive studies involve observing and describing phenomena without manipulating variables or testing hypotheses. The study described involves manipulation of the independent variable (instruction type) and comparison of outcomes, making it experimental rather than descriptive.
D. Experimental studies involve manipulating an independent variable to observe its effect on a dependent variable while controlling for other variables. The study described involves randomly assigning subjects to control and experimental groups, manipulating the type of instruction, and comparing knowledge levels before and after the intervention, indicating an experimental design.
