A nurse is educating a postoperative client on how to use an incentive spirometer. What is an accurate statement that should be included in the education plan?

Encourage the client to perform incentive spirometry 2 to 3 times every 1 to 2 hours, if possible.

Instruct the client to inhale slowly and as deeply as possible through the mouthpiece, without using the nose.

Instruct the client to inhale normally and then place the lips securely around the mouthpiece.

When the client cannot inhale anymore, the client should hold his breath and count to 10.
