A nurse develops a new nursing theory related to stress and viability
The nurse determines the theory accounts for historical events in which soldiers suffering from the stress of inadequate clothing to protect them from the cold and lack of correspondence from home had an increased mortality related to gunshot wounds. The theory will predict gunshot victims' need for proper clothing and letters from significant others as they serve in Iraq. Which criterion for theory acceptance is being validated?
a. Inclusiveness
b. Consistency
c. Accuracy
d. Simplicity
ANS: C
Correct: The accuracy of a theory is its ability to explain past occurrences while being useful in determining future outcomes.
Incorrect:
a. A theory can be validated as inclusive when it is found that it includes all concepts related to its field.
b. The consistency of a theory is its ability to deal with new entities and situations without altering its original assumptions.
d. The simplicity of the nurse's theory is not being examined in this example.
