✍️ Sample CCHT Questions & Answers

1. Which assessment finding during dialysis should prompt the technician to notify the nurse immediately?

✓ Patient reports chest pain and shortness of breath

Chest pain and shortness of breath during dialysis may indicate air embolism, cardiac event, hemolysis, or pulmonary edema, all emergencies requiring immediate nursing assessment.

2. What assessment finding during hemodialysis most strongly suggests that a patient's AVG has developed significant stenosis at the venous anastomosis?

✓ Progressively increasing venous pressures over multiple treatments with reduced blood flow rates

Rising venous pressures over time indicate increasing outflow resistance, most commonly from stenosis at or near the venous anastomosis of an AVG.

3. The most common treatment for patients with end-stage kidney disease in the United States is _____________.

✓ daytime in-center hemodialysis

Despite the availability of various modalities, daytime in-center hemodialysis remains the most prevalent treatment option for patients with end-stage kidney disease in the United States. This is often due to factors like patient preference, medical suitability, social support, and insurance coverage. It provides structured care in a supervised clinical environment.

4. In chronic kidney disease, what is the typical relationship between serum calcium and serum phosphorus levels before treatment?

✓ Calcium is low, and phosphorus is high.

Failing kidneys are unable to excrete phosphorus effectively, leading to high serum phosphorus (hyperphosphatemia). The high phosphorus levels and lack of activated Vitamin D lead to low serum calcium (hypocalcemia).

5. During hemodialysis, a patient develops sudden severe chest pain, dyspnea, and becomes cyanotic. The blood in the venous line appears pink/clear instead of dark red. What emergency is occurring?

✓ Hemolysis (red cell destruction from mechanical or chemical causes)

Pink/clear blood (hemolyzed blood) indicates massive hemolysis, a life-threatening dialysis emergency where red blood cells are being destroyed.

6. What is the appropriate intervention if a patient reports severe back and chest pain coinciding with a pink-tinged dialysate in the waste line?

✓ Stop treatment immediately, do not return blood, clamp all lines, and call for emergency assistance

Pink dialysate with pain indicates membrane rupture with potential blood leakage into dialysate or severe hemolysis, an emergency requiring immediate treatment termination.
