After 2 hours of hemodialysis, a patient develops dizziness, hypotension (80/54 mmHg), tachycardia (HR 120/min), and altered level of consciousness. What is the priority nursing action?
Appeared in: NORCET 10 Mains
Explanation
The patient is experiencing dialysis-induced hypotension, a critical complication from rapid fluid removal.
The priority is to correct the hypovolemia and stabilize circulation.
Stopping or slowing the dialysis immediately halts the cause of the fluid loss.
Administering 0.9% normal saline, an isotonic IV fluid, rapidly restores intravascular volume, raising blood pressure and improving organ perfusion.
Why Other Options Were Wrong
Option B: Continuing dialysis would remove more fluid, worsening the hypotension and potentially leading to cardiovascular collapse.
Option C: A combination of severe hypotension, tachycardia, and altered mental status is a medical emergency, not a normal finding during dialysis.
Option D: Giving oral fluids to a patient with an altered level of consciousness poses a significant risk of aspiration. Additionally, oral rehydration is too slow to correct acute, severe hypotension.

Clinical Relevance
Nursing practice connection: Safe nursing care depends on performing Management of Complications during Hemodialysis in the correct sequence, documenting the action clearly, and monitoring for the expected response.
Dialysis-induced hypotension is the most common complication during hemodialysis, and nurses must be able to recognize and intervene immediately to prevent severe adverse outcomes like shock or cardiac events.
The nurse's role includes frequent monitoring of vital signs and patient symptoms throughout the dialysis treatment to allow for early detection and intervention.
What if? If the patient was hypotensive but fully conscious and alert, the nurse would still slow the dialysis and administer saline, but would also place the patient in a Trendelenburg position (legs elevated) to enhance venous return to the heart.
How to Approach the Question
First, analyze the patient's clinical presentation. The key signs are dizziness, severe hypotension (BP 80/54), compensatory tachycardia (HR 120), and altered level of consciousness.
Recognize that this cluster of symptoms points to a state of circulatory compromise or shock, likely caused by the dialysis procedure itself (rapid fluid removal).
Apply the principle of prioritization: address the most life-threatening problem first. The immediate threat is circulatory collapse due to hypovolemia.
Evaluate the options based on this priority. The correct action must stop the cause and reverse the problem.
Option A directly addresses both: it stops the fluid removal (the cause) and starts fluid replacement (the solution).
Eliminate other options: Continuing dialysis (B) worsens the problem. Ignoring it (C) is negligent. Giving oral fluids (D) is dangerous and too slow.
