Quasi-experimental ANS: B PTS: 1 DIF: Cognitive level: Applying (Application) REF: pp. 32-33 2. The researcher wants to learn whether there is a relationship between parental education and emergency room use among children who have asthma. Which type of research study will this researcher use? a. Basic b. Correlational c. Historical d. Phenomenological ANS: B PTS: 1 DIF: Cognitive level: Applying (Application) REF: pp. 32-33 3.

Quasi-experimental ANS: D PTS: 1 DIF: Cognitive level: Understanding (Comprehension) REF: p. 34 5. The nurse participates in data collection for a clinical drug trial in which subjects are randomly assigned to either a treatment or a placebo group to measure the effects of the drug on a specific outcome. This is which type of study? a. Correlational b. Descriptive c. Experimental d. Quasi-experimental ANS: C PTS: 1 DIF: Cognitive level: Applying (Application) REF: p. 34 6.

The study would be described as: a. applied research. b. basic research. c. descriptive research. d. phenomenological research. ANS: A PTS: 1 DIF: Cognitive level: Applying (Application) REF: p. 35 7.

Partially controlled, laboratory ANS: C PTS: 1 DIF: Cognitive level: Applying (Application) REF: pp. 36-37 11. When conducting a research study using a convenience sample of all first grade students from two classrooms in a nearby school, the nurse researcher may increase the sample control by: a. assigning one classroom to the experimental group and the other
