An example of a predictive type of question that a nurse might use for research is which of the following?

1. “What creates an increase in stress levels?”
2. “How often does the stress reaction occur?”
3. “What does guided imagery mean to clients?”
4. “If guided imagery is used, will stress levels be reduced?”

ANSWER

ANS: 4
Questioning whether stress will be reduced is an example of a predictive type of question be-cause it connects stress reduction with the use of guided imagery.
Asking what increases stress explores factors that impact a phenomenon. It is not a predictive type of question.
Asking how often stress increases does not predict any outcome, but rather focuses on frequency of a response, which could be used in data collection.
Asking what guided imagery means does not predict any type of outcome, but rather explores meaning in order to gain understanding.
