Final answer:
The statement is false, as PCA pumps allow for better pain management and do not necessarily prevent early ambulation, which is essential to prevent complications like deep vein thrombosis.
Step-by-step explanation:
The statement that a disadvantage of PCA (Patient-Controlled Analgesia) pumps is that the client does not ambulate as early due to the machine is false. PCA pumps are designed for pain management that allows patients to administer their own pain medication within preset limits. This method can lead to better pain control, greater patient satisfaction, and the potential for increased mobility. Early ambulation is encouraged in many medical treatments and protocols because it helps to prevent complications such as deep vein thrombosis and pulmonary embolism. The PCA pump, being portable and typically attached to the patient via an intravenous line, does not necessarily impede ambulation when used appropriately and with proper monitoring.
