a. Coughing.
b. Diaphragmatic breathing.
c. Incentive spirometry.
d. Leg exercises.

Question 2

The first step in evidence-based practice is to ask a clinical question. In doing so, the nurse needs to realize that in researching interventions, the question

a. Is more important than its format.
b. Will lead you to hundreds of articles that must be read.
c. May be easier if in PICO format.
d. May be more useful the more general it is.

Answer to Question 1

D
After general anesthesia, circulation slows, and when the rate of blood slows, a greater tendency for clot formation is noted. Immobilization results in decreased muscular contractions in the lower extremities; these promote venous stasis. Coughing, diaphragmatic breathing, and incentive spirometry are utilized to decrease atelectasis.

Answer to Question 2

C
The PICO format allows the nurse to ask questions that are intervention focused. Inappropriately formed questions will likely lead to irrelevant sources of information. It is not beneficial to read hundreds of articles. It is more beneficial to read the best four to six articles that specifically address the question. The more focused the question asked, the easier it will become to search for evidence in the scientific literature.
