Increase the ultrafiltration rate to remove more fluid quickly 2. Decrease the ultrafiltration rate and administer normal saline **✔ 정답** 3. Stop the dialysis treatment immediately and call the physician 4. Administer calcium gluconate and continue dialysis **정답: 2** ## 해설 The client's symptoms indicate dialysis disequilibrium syndrome and hypovolemia from rapid fluid removal. Decreasing ultrafiltration rate and administering normal saline stabilizes blood pressure and prevents further complications. Other options may worsen hypotension or are not immediate interventions. ## 심화 해설 Clinical Scenario Analysis This client is presenting with a classic triad of intradialytic hypotension (IDH): severe muscle cramps, hypotension, and dizziness. IDH is a frequent and distressing complication of hemodialysis, often reducing the efficiency of the procedure and leading to adverse clinical outcomes [1]. The symptoms occur because rapid fluid removal via ultrafiltration causes a decline in intravascular volume that outpaces the body's compensatory mechanisms, leading to decreased tissue perfusion. Muscle cramps, specifically, are a common symptom associated with these hypotensive episodes and often trigger rescue interventions [2]. The immediate priority is to restore intravascular volume and stabilize blood pressure without abruptly terminating the treatment, which would waste the patient's blood in the extracorporeal circuit. Why the Correct Answer is Option 2 The most appropriate immediate intervention is to **decrease the ultrafiltration rate and administer normal saline**. Reducing the ultrafiltration rate immediately slows the removal of fluid from the intravascular space, directly addressing the root cause of the hypotension. Administering a normal saline bolus (typically 100-200 mL) expands the intravascular volume, rapidly reversing hypotension and alleviating associated symptoms like cramps and dizziness. This approach aligns with standard nursing practice for managing IDH, where interventions are required to address symptomatic drops in blood pressure [1]. Why the Other Options Are Incorrect - **Option 1: Increase the ultrafiltration rate to remove more fluid quickly.** This action is contraindicated. Increasing the ultrafiltration rate would exacerbate the intravascular volume depletion, worsening the hypotension, cramps, and dizziness. It directly contradicts the physiological goal of stabilizing the patient's hemodynamic status. - **Option 3: Stop the dialysis treatment immediately and call the physician.** While the physician should be notified, stopping dialysis immediately is not the first-line nursing intervention. Abruptly terminating the session results in significant blood loss for the patient (as the blood in the extracorporeal circuit cannot be returned) and fails to complete the prescribed fluid removal. The nurse should first implement independent interventions to manage the IDH episode. If the patient does not respond to a fluid bolus and reduced ultrafiltration, then stopping treatment and notifying the physician becomes the next step. - **Option 4: Administer calcium gluconate and continue dialysis.** Calcium gluconate is not the standard treatment for IDH-related muscle cramps. While electrolyte imbalances can contribute to cramps, the immediate cause in this scenario is hypovolemia-induced hypotension. The priority is volume expansion with normal saline. Administering calcium gluconate does not address the underlying hemodynamic instability. Deeper Pathophysiology and Nursing Management The pathophysiology of IDH is primarily driven by a mismatch between the ultrafiltration rate and the plasma refilling rate. As fluid is rapidly removed from the vascular compartment during dialysis, the body's ability to shift fluid from the interstitial space back into the vessels is overwhelmed. This leads to a critical drop in central blood volume, reduced cardiac output, and subsequent hypotension. The development of muscle cramps is thought to be related to hypoperfusion of the muscles, causing local ischemia and involuntary contractions [2]. Research indicates that while threshold-based blood pressure definitions of IDH are strongly associated with mortality, real-time adverse symptoms like cramps and dizziness are the clinical triggers that necessitate immediate nursing intervention . Therefore, the nurse's role is to promptly recognize these symptoms, connect them to the likely cause of rapid fluid shifts, and intervene to restore hemodynamic stability by decreasing fluid removal and administering a volume expander like normal saline. Preventive strategies, such as nurse-led intradialytic stretching exercises, have also been shown to reduce the burden of muscle cramps, highlighting the importance of proactive nursing care [2].

Administer a bolus of 100-200 mL of normal saline to expand intravascular volume. Place the client in the Trendelenburg position to promote venous return. Monitor vital signs closely until the systolic blood pressure stabilizes above 100 mmHg and symptoms resolve. CautionDo not stop the dialysis machine abruptly as this causes blood loss in the circuit. Avoid raising the ultrafiltration rate, which will critically worsen the intravascular volume deficit. ## 핵심 개념 - **Intradialytic Hypotension (IDH)** — A drop in blood pressure during hemodialysis, commonly caused by rapid fluid removal exceeding the body's compensatory plasma refill rate. - **Ultrafiltration Rate** — The speed at which fluid is removed from the patient's blood during dialysis, a primary modifiable factor in managing hypotension. ## 같은 주제 문제 - [A nurse is caring for a client receiving hemodialysis.
