Answer to Question 1

A

Feedback
A The nurse should instruct the patient to inhale deeply and slowly for 3 to 5 seconds.
B Inhalation time should not be for 10 to 15 seconds.
C Inhalation time should not be for 15 to 20 seconds.
D Inhalation time should not be for 25 to 30 seconds.

Answer to Question 2

C
The patient has respiratory acidosis from CO2 retention. Increasing rate and depth of respiration will allow the patient to blow off excess carbon dioxide, and this will begin to correct the imbalance. Checking the urine color is not a necessary assessment. The Trendelenburg position likely would make it more difficult for the patient to breathe and should be avoided. Placing the patient in high Fowler's position may make the patient more comfortable, but it is not necessary.
