Answer to Question 1
4. Studying the ability of an aging population to care for itself.
Rationale:
The population is aging as the baby boomers begin to retire. An important replication study would be to restudy the ability of this age group to care for itself so that cost-effective measures can be instituted to provide care for this expanding group. Effectiveness of supplies on cost is usually an ongoing project conducted in most hospitals as health care costs increase. Studying a family's ability to adapt to acute health problems is not a demographic issue. New technology is not a demographic issue.
Answer to Question 2
3. Participate in research as the principle investigator.
Rationale:
Nurses should have training beyond the baccalaureate level to participate as a principle investigator. Nurses from all levels can participate in research projects, incorporate results into client care, and identify areas of needed research. In fact, nurses are now expected to participate in nursing research.
