Answer to Question 1

ANS: D
The quantitative research methods are classified into four categories: (1) descriptive, which defines the magnitude of a concept and its characteristics, (2) correlational, which determines association between or among variables, (3) quasi-experimental, which tests an intervention and lacks either a control group or random assignment, and (4) experimental, which tests an intervention and includes both a control group and random assignment. This research study tests an intervention and includes both a control group and random assignment.

Answer to Question 2

ANS: A
Outcomes research emerged as an important methodology for documenting the effectiveness of health care services in the 1980s and 1990s. This type of research evolved from the quality assessment and quality assurance functions that originated with the professional standards review organizations (PSROs) in 1972. During the 1980s, William Roper, the director of the Health Care Finance Administration (HCFA), promoted outcomes research for determining the quality and cost-effectiveness of patient care. Intervention research investigates the effectiveness of a nursing intervention in achieving the desired outcome or outcomes in a natural setting. Through the use of ethnographic research, different cultures are described, compared, and contrasted to add to our understanding of the impact of culture on human behavior and health. Experimental studies have three main characteristics: (1) a controlled manipulation of at least one treatment variable (independent variable), (2) administration of the treatment to some of the subjects in the study (experimental group) and not to others (control group), and (3) random selection of subjects or random assignment of subjects to groups, or both. Experimental studies usually are conducted in highly controlled settings, such as laboratories or research units in clinical agencies.
