Final answer:
During hemodialysis, if a client becomes hypotensive, the immediate nursing action is to administer a 250 ml normal saline bolus to restore blood pressure. Option b) is correct.
Step-by-step explanation:
In the event of hypotension during hemodialysis in a client, the nurse's immediate response involves administering a 250 ml normal saline bolus. This swift intervention is grounded in the isotonic nature of normal saline concerning body fluids, facilitating the rapid restoration of vascular volume and, consequently, an elevation in blood pressure. Recognizing the critical importance of addressing hypotension promptly during hemodialysis, the nurse opts for a solution that aligns with physiological balance and provides a swift corrective measure.
Contrary to this targeted approach, alternative actions may prove less effective or even inappropriate. Increasing the blood flow into the dialyzer might exacerbate hypotension, as it could further deplete the available circulatory volume. Similarly, administering 5% dextrose in water may contribute to fluid overload without directly addressing the immediate issue of hypotension. Lowering the client's legs and feet, while offering temporary relief, does not constitute a definitive treatment for the underlying problem.
In essence, the nurse's choice of a normal saline bolus aligns with the goal of promptly and effectively restoring vascular volume, emphasizing the importance of selecting interventions that address the specific needs of the client undergoing hemodialysis.
