Correct Answer is A

Explanation

A. This statement indicates that the client may not fully understand the care required for the drainage tubes. Drainage tubes typically do not "fall out" on their own; they need to be removed by a healthcare provider. The client should be instructed to care for the tubes, monitor drainage, and report any concerns to their healthcare provider.

B. It is appropriate to measure the drainage each day and report it if it exceeds the expected amount. This helps ensure that the surgical site is healing properly.

C. The client should be cautious with the positioning of the drainage tubes to avoid kinking or pulling, which could interfere with drainage and cause complications.

D. A foul odor from the drainage could indicate an infection, so it is appropriate for the client to contact their primary healthcare provider if this occurs.
