Albumin is an important laboratory test that provides information about the patient’s: A. Cardiac function B. Nutritional status C. Potassium level D. Bone density Correct Answer: B. Nutritional status Rationale: Albumin reflects protein stores and nutritional health. Low levels are associated with poor outcomes and increased morbidity. All of the following are phosphate binders EXCEPT: A. Calcium acetate B. Sevelamer C. Aluminum hydroxide D. Vitamin B12 Correct Answer: D. Vitamin B12 Rationale: Vitamin B12 is a vitamin supplement, not a phosphate binder. Phosphate binders reduce phosphorus absorption in dialysis patients. All of the following may be signs and symptoms of an infected access EXCEPT: A. Redness B. Warmth C. Drainage D. Numbness and tingling Correct Answer: D. Numbness and tingling Rationale: Infection typically presents with redness, warmth, swelling, and drainage—not numbness or tingling. Asepsis is defined as: A. Clean technique B. The absence of disease-producing organisms C. Hand hygiene D. Sterilization Correct Answer: B. The absence of disease-producing organisms Rationale: Asepsis refers to a condition free from pathogenic microorganisms. Based on Mrs. Smith’s prescribed fluid removal for a 4-hour treatment, the ultrafiltration rate is: A. 1,000 mL/hr B. 1,250 mL/hr C. 1,385 mL/hr D. 1,500 mL/hr Correct Answer: C. 1,385 mL/hr Rationale: Ultrafiltration rate equals total fluid to be removed divided by treatment time. If a fistula needle becomes contaminated prior to treatment, the technician should: A. Wipe it with alcohol B. Flush it with saline C. Discard the needle D. Use it carefully Correct Answer: C. Discard the needle Rationale: Any contaminated needle must be discarded to prevent infection. Dialysate that is too hot may cause: A. Hypotension B. Clotting C. Hemolysis D. Infection Correct Answer: C. Hemolysis Rationale: Excessive dialysate temperature can damage red blood cells, causing hemolysis. Dry weight is defined as the: A. Admission weight B. Target weight after dialysis C. Weight at which the patient has no edema or pulmonary fluid and normal BP D. Highest post-treatment weight Correct Answer: C. Weight at which the patient has no edema or pulmonary fluid and normal BP Rationale: Dry weight represents the patient’s optimal weight without excess fluid. A low venous pressure alarm during dialysis is most likely caused by: A. Kinked venous line B. Clotted dialyzer C. Disconnection of the bloodline D. High blood flow Correct Answer: C. Disconnection of the bloodline Rationale: A sudden drop in venous pressure usually indicates a disconnection or leak. Biohazardous waste includes any material exposed to: A. Dialysate B. Saline C. Blood D. Gloves only Correct Answer: C. Blood Rationale: Materials contaminated with blood are considered biohazardous and require special disposal. Decreasing the patient’s prescribed blood flow rate affects the rate of: A. Osmosis B. Filtration C. Diffusion D. Convection Correct Answer: C. Diffusion Rationale: Lower blood flow reduces the concentration gradient, decreasing diffusion efficiency. If a venous needle infiltrates, the technician should first: A. Notify the nurse B. Apply ice C. Stop the pump D. Remove both needles Correct Answer: C. Stop the pump Rationale: Stopping the pump prevents further blood leakage and tissue damage. Dialysate pH should be maintained between: A. 6.0–6.5 B. 6.5–7.0 C. 7.0–7.4 D. 7.5–8.0 Correct Answer: C. 7.0–7.4 Rationale: Dialysate pH must be near physiologic range to maintain acid-base balance. If foam is visible in the venous drip chamber and the air detector alarms, the technician should: A. Restart the pump B. Clamp the venous line C. Increase blood flow D. Silence the alarm Correct Answer: B. Clamp the venous line Rationale: Clamping prevents air from entering the patient’s bloodstream. If a patient feels chilled during dialysis, the technician should also: A. Increase dialysate temperature B. Stop treatment C. Take the patient’s temperature D. Decrease blood flow Correct Answer: C. Take the patient’s temperature Rationale: Chills may indicate fever or reaction; temperature assessment is necessary. ESRD-specific tests such as BUN, creatinine, and URR are: A. Nutritional markers B. Indicators of adequacy of renal replacement therapy C. Infection markers D. Cardiac enzymes Correct Answer: B. Indicators of adequacy of renal replacement therapy Rationale: These tests evaluate how effectively dialysis removes waste. Excess fluid is forced out of the blood and into the dialysate by: A. Diffusion B. Osmosis C. Ultrafiltration D. Adsorption Correct Answer: C. Ultrafiltration Rationale: Ultrafiltration removes excess fluid by applying pressure across the membrane. Fluid to be removed divided by treatment time equals: A. Blood flow rate B. Dialysate flow rate C. Ultrafiltration rate D. Clearance Correct Answer: C. Ultrafiltration rate Rationale: UF rate is calculated by dividing total fluid removal by treatment hours. Germicide rebound occurs due to: A. Air embolism B. Inadequate dialyzer priming C. Low blood flow D. Clotting Correct Answer: B. Inadequate dialyzer priming Rationale: Insufficient rinsing allows residual sterilant to leach into blood during treatment. Hives, itching, chest tightness, and respiratory distress are signs of: A. Hypotension B. Hemolysis C. Anaphylaxis D. Hyperkalemia Correct Answer: C. Anaphylaxis Rationale: These are classic signs of a severe allergic reaction. Hyperkalemia can lead to: A. Hypertension B. Cardiac arrest C. Infection D. Hypoglycemia Correct Answer: B. Cardiac arrest Rationale: Elevated potassium can cause fatal cardiac arrhythmias. In reuse processing, blood path integrity is tested to: A. Check temperature B. Check dialyzer for total cell volume C. Measure pH D. Test conductivity Correct Answer: B. Check dialyzer for total cell volume Rationale: Total cell volume testing ensures the dialyzer fibers are intact and usable. Lidocaine is administered via which route? A. Intravenous B. Oral C. Subcutaneous D. Intramuscular Correct Answer: C. Subcutaneous Rationale: Lidocaine is injected subcutaneously to numb the cannulation site. Low albumin levels in dialysis patients are linked to: A. Improved outcomes B. Higher hospitalization and death rates C. Better appetite D. Increased muscle mass Correct Answer: B. Higher hospitalization and death rates Rationale: Hypoalbuminemia is associated with increased morbidity and mortality.
