A nurse is contributing to the plan of care for a client who is undergoing hemodialysis. Which of the following interventions should the nurse suggest?

This scenario focuses on clinical planning for a client undergoing maintenance hemodialysis. It requires applying renal physiology, vascular access assessment guidelines, and pharmacodynamics to optimize dialysis safety, prevent access complications, and avoid intraprocedural hemodynamically unstable events like severe hypotension. Choice A rationale Arteriovenous grafts require frequent monitoring to ensure patency and detect early thrombosis. Checking the site only once per day is insufficient; it should be assessed at least every four hours or per protocol. Choice B rationale Auscultating the carotid arteries evaluates for central vascular stenosis or bruits. While clinically relevant for stroke risk, it does not directly assess or protect the integrity of the peripheral hemodialysis vascular access site. Choice C rationale The kidneys normally excrete potassium to maintain levels between 3.5 and 5.0 mEq/L. Hyperkalemia is a lethal risk in renal failure, necessitating pre-dialysis serum checks to guide safe dialysate potassium concentration adjustments. Choice D rationale Antihypertensive medications cause peripheral vasodilation and drop blood pressure. Administering them immediately before hemodialysis compounds the fluid-removal drop, potentially precipitating severe, dangerous intraprocedural hypotension and vascular access clotting.
