A nurse is caring for a client following a cardiac catheterization who has hives and urticaria following administration of IV contrast dye. Which of the following medications should the nurse plan to administer?

C. The CPM machine should be used during designated therapy sessions as prescribed by the healthcare provider. Turning it off during meals allows the client to focus on eating without interference from the machine.

A The range of motion settings on the CPM machine should be adjusted gradually according to the client's tolerance and prescribed therapy plan. Rapidly increasing the range of motion could cause discomfort, pain, or even injury to the client's knee joint. Therefore, the nurse should not increase the range of motion rapidly.

B Storing the CPM machine on the floor is not ideal because it can increase the risk of contamination or damage to the equipment. The machine should be stored on a clean, stable surface when not in use to prevent accidental damage or exposure to dirt and debris.

D. Regular checks of the CPM machine's settings are important, but every 12 hours may not be frequent enough to ensure the machine is functioning correctly and safely.

B. The appropriate action for a nurse to take would be to check for air leaks in the system. This can be done by clamping the tubing momentarily to see if the bubbling stops, which would suggest the presence of a leak.

A The drainage system should always be kept below the level of the chest and should not be raised or emptied unless specifically indicated.

C. Emptying the collection chamber is typically unnecessary unless it is nearing full capacity. Continuous bubbling in the water seal chamber does not indicate that the collection chamber needs immediate emptying.

D. Squeezing the tubing can disrupt the functioning of the drainage system and is not recommended. Drainage should flow passively into the collection chamber without external manipulation.
