36. The healthcare professional plans to check for patency of all drainage devices by ensuring that such devices:
Answer: B
All drainage devices should be open to ensure patency.
To check for patency of all drainage devices, it is essential that these devices are open. This allows for the free flow of fluids, which is critical for their proper functioning.
A) contain solids.
This option is incorrect because the presence of solids in drainage devices can indicate a blockage or clogging, which would compromise their patency. Patency requires unobstructed flow, which is not guaranteed by the presence of solids.
B) are open.
This option is correct as ensuring that drainage devices are open is crucial for confirming their patency. Open devices allow for the unobstructed passage of fluids, which is necessary for effective drainage and patient safety.
C) contain liquid.
While the presence of liquid is often expected in functioning drainage devices, it does not specifically indicate that the device is patent. A device could contain liquid but still be obstructed, thus failing to allow for proper drainage.
D) are closed.
This option is incorrect because closed drainage devices would not permit any flow, indicating they are not patent. Patency requires the devices to be open to facilitate drainage.
Conclusion
In summary, the correct answer is that drainage devices must be open to ensure their patency, which allows for proper functioning and prevents complications. Other options fail to capture the essential requirement of unobstructed flow necessary for effective drainage.
