Answer to Question 1

ANS: D

Feedback
A This statement includes an intervention (insertion of an enteral feeding tube) and a population (adult patients) but does not include the other PICO elements.
B This statement includes comparison (differences between feeding tubes) but does not include the other PICO elements.
C This statement includes only a problem and needs to be further refined to include the PICO elements.
D This statement is worded as a clinical question and includes the four PICO elements: population (adult patients), intervention (methods of determining stomach placement), comparison (among methods), and outcome (prevent aspiration).

Answer to Question 2

ANS: C

Feedback
A Postoperative older adult patients represent the population to be studied.
B Early postoperative period indicates the timing of the intervention.
C Warm and cold applications represent the independent variables, which will be manipulated and influence the dependent (outcome) variable resolution of IV infiltrations.
D Resolution of IV infiltrations represents the dependent (outcome) variable of the study.
