A nurse is caring for a client undergoing hemodialysis. Which intervention is essential to prevent dialysis-related hypotension?
Increasing the dialysate temperature.
Limiting fluid removal during dialysis.
Encouraging the client to consume a high-sodium diet.
Administering intravenous hypertonic saline during dialysis.
The Correct Answer is B
A. Incorrect. Increasing the dialysate temperature can lead to vasodilation and potentially exacerbate hypotension during dialysis.
B. Correct. Limiting fluid removal during dialysis is essential to prevent excessive fluid loss, which can cause hypotension and potentially lead to intradialytic hypotension.
C. Incorrect. Encouraging a high-sodium diet is not the primary intervention to prevent dialysis-related hypotension. It may be recommended for some clients to manage hyponatremia, but fluid management is more critical.
D. Incorrect. Administering intravenous hypertonic saline during dialysis is not a routine intervention to prevent hypotension. It may be used in specific cases, but fluid management is the primary approach.

Correct Answer is A
Explanation
A) This statement is accurate. Palpating for a thrill or vibration over the AV fistula site is a critical assessment to ensure proper functioning. A thrill indicates adequate blood flow through the fistula, which is essential for effective hemodialysis.
B) This statement is incorrect. Auscultating for bruits over the radial artery is not related to the AV fistula assessment. The bruit is the sound of blood flow in the fistula, which is best assessed directly over the fistula site.
C) This statement is incorrect. Checking for distal pulses in the lower extremities is not related to the assessment of an AV fistula. The AV fistula is typically created in the upper extremity.
D) This statement is incorrect. Assessing for swelling and tenderness in the neck is not related to the AV fistula assessment. Swelling and tenderness may be related to other issues but are not specific to AV fistula functioning.
Correct Answer is D
Explanation
A) This statement is incorrect. Hypermagnesemia (elevated magnesium levels) can be a concern in ESRD, but it is not a primary indication for initiating dialysis. Magnesium levels can be managed through dietary restrictions and medications without the need for dialysis.
B) This statement is incorrect. Hyperphosphatemia (elevated phosphorus levels) is a common issue in ESRD, but it is not a primary indication for initiating dialysis. Clients with ESRD may receive phosphate binders to control phosphorus levels without necessarily needing immediate dialysis.
C) This statement is incorrect. Hyperkalemia (elevated potassium levels) is a concern in ESRD, but it is not the primary indication described in the scenario. While hyperkalemia may occur with fluid overload, the primary concern in this case is the hypervolemia and its associated symptoms.
D) Hypervolemia (severe fluid overload) is a critical indication for initiating dialysis in clients with end-stage renal disease. Dialysis helps remove excess fluid from the body and can relieve symptoms such as pulmonary edema and hypertension.
