Answer to Question 1

ANS: C
Two types of systems have been identified: open and closed. An open system, such as a human organism or processes like the nursing process, interacts with the environment. A closed system does not interact with the environment.

Answer to Question 2

ANS: A
Prescriptive theories guide nursing research to develop and test specific nursing interventions. Grand theories are broad in scope and complex, and require further specification through research. Descriptive theories do not direct specific nursing activities but help to explain patient assessment. The phenomena within middle-range theories tend to cross different nursing fields and reflect a wide variety of nursing care situations.
