A nurse is searching for evidence in an effort to answer a series of clinical questions related to childhood asthma. In which of the following areas is qualitative research likely to be most valuable?
A) Identifying if nebulized delivery of bronchodilators is superior to the use of metered-dose inhalers
B) Identifying which environmental exposures are most closely linked to the incidence of bronchospasm
C) Identifying how a family's accessibility to primary care affects the course of a child's asthma
D) Identifying values that determine children's choices of where and when to use their metered-dose inhalers
Question 2
The historical incidence of deep vein thrombosis in medical patients at a university hospital was 2.5. This figure dropped to 2 among an experimental group during the implementation of a new prophylaxis regimen.
What is the nurse's most accurate interpretation of this finding?
A) The relative risk of DVT among medical patients is 2/100.
B) The regimen results in a 20 relative risk reduction.
C) The absolute risk of DVT among the control group is 2.5.
D) The results of the intervention are valid and reliable.
