What is a potential drawback of the immersion technique mentioned in the material?

• A. Pressure hurts patient
• B. Heat is uniformly distributed
• C. Improves patient comfort without issues
• D. Requires no coupling agent

Answer: (A)

Immersion therapy relies on the hydrostatic pressure of water on the body. As you go deeper into the water, the external pressure increases, which can compress tissues and affect breathing or circulation. This added pressure can be uncomfortable or painful for many patients, especially those with edema, wounds, vascular issues, or cardiopulmonary conditions. That potential for discomfort is the main drawback to watch for, prompting careful assessment, possible shallower immersion, shorter sessions, or closer monitoring. The other statements don’t describe a drawback of immersion. Heat isn’t guaranteed to be distributed uniformly in water, so even heating isn’t always even. The idea that it improves patient comfort without issues contradicts the reality that some patients may experience pain or discomfort from the pressure. And the notion of needing no coupling agent isn’t relevant to immersion therapy, which doesn’t rely on a coupling medium.
