What type of research design is used in the research study described in this statement? "To detect differences in the knowledge levels of older adults regarding osteoporosis, subjects were randomly assigned to a control group, which received printed materials, and an experimental group, which received computerized instruction. The same pretest and posttest were administered to all subjects."
Longitudinal.
Quasi-experimental.
Descriptive.
Experimental.
The Correct Answer is D
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.

Correct Answer is D
Explanation
A. The statement does not provide evidence to suggest that oncology nurses have significantly more positive attitudes toward hospice care than nurses without oncology experience.
B. While past experience with hospice is mentioned as one of the factors associated with discussing hospice care, the statement does not imply that it is the greatest determinant.
C. The statement suggests that nurses who have had positive experiences with hospice are more likely to discuss hospice care, but it does not compare their attitudes to those without such experiences.
D. This interpretation accurately reflects the findings presented in the statement, which indicate a positive correlation between nurses' experience with hospice and their likelihood of discussing hospice care with terminally ill clients.
Correct Answer is A, C, D, E, B
Explanation
A. Employee 4 is the most proficient with the lowest average number of skin punctures per valid reading at 1.005, indicating a high level of skill and efficiency in obtaining blood glucose measurements.
C. Employee 1 follows closely with an average of 1.01 punctures, showing competence nearly on par with Employee 4.
D. Employee 2 has a slightly higher average of 1.08, suggesting a good proficiency but with a marginally increased likelihood of requiring additional punctures.
E. Employee 5's average of 1.12 punctures is higher still, indicating a lesser proficiency than Employees 4, 1, and 2.
B. Employee 3, with the highest average of 1.7 punctures, is the least proficient, as this number suggests a significantly higher probability of needing multiple punctures to obtain a valid reading, which could indicate a need for further training or practice.
