What can indicate a need for intervention during dialysis?

The correct choice indicates that "Signs of distress or discomfort" during dialysis are critical indicators that warrant immediate intervention. During treatments such as dialysis, patients can experience various physical and emotional responses. The presence of distress—such as pain, nausea, or anxiety—can signal complications or adverse reactions to the treatment that need to be addressed promptly to ensure the patient's safety and comfort.

For example, if a patient exhibits signs of shortness of breath, excessive blood pressure changes, or any acute discomfort, these symptoms may indicate that the patient may be experiencing a serious reaction or complication, such as fluid overload or dialyzer reactions. Recognizing and acting on these distress signals can prevent further health complications and ensure a more comfortable experience for the patient.

Other options like normal vital signs or stable blood sugar levels may suggest that the patient is stable and not requiring immediate intervention. Likewise, a patient's expression of contentment may indicate a positive experience but doesn't necessarily mean that interventions are unnecessary—it's the signs of distress that demand prompt action for the patient's wellbeing.
