  1. A hemodialysis patient develops sudden chest pain, dyspnea, and hypotension during treatment. What is the FIRST nursing action?

    Answer: Stop dialysis, return blood to patient, and call for emergency help

    Sudden cardiopulmonary emergency during HD requires stopping treatment, returning blood to prevent additional fluid/electrolyte shifts, and activating emergency response.

  2. Which electrolyte imbalance is MOST commonly associated with muscle cramps during hemodialysis?

    Answer: Rapid ultrafiltration causing hypovolemia

    Muscle cramps during HD are most often caused by rapid fluid removal leading to intravascular volume depletion and tissue hypoperfusion.

  3. A patient's dialysis access shows a bruit that has changed from soft to high-pitched. What does this finding indicate?

    Answer: Possible stenosis or partial occlusion of the access

    A high-pitched or harsh bruit replacing a soft, low-pitched one suggests turbulent flow from stenosis, which requires prompt evaluation.

  4. What is the recommended target range for dialysis adequacy (Kt/V) in hemodialysis patients per KDOQI guidelines?

    Answer: ≥1.2 per session

    KDOQI guidelines recommend a minimum delivered spKt/V of 1.2 per hemodialysis session to ensure adequate solute clearance.

  5. Which peritoneal dialysis complication is characterized by cloudy effluent, abdominal pain, and fever?

    Answer: Peritonitis

    Peritonitis presents with cloudy effluent (WBC >100 cells/mm³ with >50% PMNs), abdominal pain, and fever in PD patients.

  6. A patient on peritoneal dialysis has persistent poor ultrafiltration. Which intervention should the nurse anticipate?

    Answer: Switch to higher dextrose concentration dialysate

    Higher dextrose concentration (2.5% or 4.25%) creates a stronger osmotic gradient to enhance fluid removal when ultrafiltration is inadequate.

  7. When assessing a patient for adequacy of PD, the nurse calculates a weekly Kt/V of 1.5. How should this be interpreted?

    Answer: Inadequate — target is ≥1.7

    KDOQI recommends a minimum total weekly Kt/V of ≥1.7 for peritoneal dialysis; a value of 1.5 is below this target and requires intervention.
