Answer to Question 1
ANS: A
The nurse should compare findings of the two legs as these findings may be normal for the client. If a difference is observed, the nurse notifies the provider. Documentation should occur after the nurse has all the data. Elevating the left leg will not improve perfusion if there is a problem.
Answer to Question 2
ANS: B
Because CT uses iodine-based contrast material, the nurse assesses the client for allergies to iodine or seafood (which often contains iodine). The other actions are not needed.
