Question 1: Conductivity is how well a fluid will transfer an electrical charge. It is a measure of ions in solution. A conductivity meter measures the electrolyte level of dialysate to be sure it is within safe limits.

Answer:

Conductivity Monitor Question 2: Creatinine clearance is a urine test that measures how well the kidneys remove creatinine from the blood in a certain amount of time . As kidney disease worsens, creatinine clearance will fall to 10% of normal or less.

Answer:

Crenation Question 3: Cellulose is a fiber that forms the cell walls of plants. Cellulose acetate was used as the first dialyzer membrane by Dr. Willem Kolff in 1942. It was also the first substance used to make reverse osmosis membranes for water treatment. To form a membrane, cellulose can be dissolved in a solution ith copper salts and ammonium, then spun into sheets or hollow fibers.Cellulose dialyzer membranes are the most likely to cause first - use syndrome, because they are not biocompatible.

Answer:

Central Venous Stenosis

Question 4: An arteriole is a small artery.

Answer:

Artery

Question 5: Aseptic means sterile or germ-free.

Answer:

Aseptic technique

Question 6: Acquired Immunodeficiency Syndrome - AIDS

Answer:

Acute Kidney Failure Question 7: CRRT is slow, ongoing form of dialysis. It uses the patient's heart or blood pump to move blood through an extracorporeal circuit. CRRT is most often done for may hours to gently remove extra fluid and some wastes in patients who are too ill or unstable for standard hemodialysis. A cartridge with a semipermeable membrane - like a dialyzer - is used.

Answer:

Countercurrent flow Question 8: Cardiac output is the amount of blood passing through the heart in a certain period of time. Having an AV fistual or graft causes a 10% increase in cardiac output. This causes a 10% increase in the size of the heart. Patients who can't tolerate this increase in cardiac output cant's have AV fistulae or grafts.

Answer:

Catabolism Question 9: Concentration is the level of solute dissoved in a measure of fluid. A highly-concentrated solution has more solutes. A less -concentrated - more dilute solution has less solutes. One task of healthy kidneys is to control the concentration of urine so the right amounts of fluid and other substances stay in the body. In dialysis, the concentration of each of substance in dialysate must be correct to ensure a safe and effective treatment.

Answer:

Conditions for Coverage

Question 10: Bacteria are microscopic, single-celled organisms that can cause disease. Bacteria are classified as Gram-positive or Gram-negative by the color they turn on a test called Gram's stain.

Answer:

Base Question 11: The blood pump is part of the hemodialysis delivery system. It pushes the patient's blood through the extracorporeal circuit at a fixed rate of speed. During a treatment, the blood tubing is threaded beteen the pump head and rollers. the rollers move blood through the circuit and back to the patient.

Answer:

Blood Pump Segment Question 12: In the buttonhole technique, dialysis needles are placed in a fistula - not a graft- into the same holes at the same angle. Over 3 - 4 weeks, this creates pierced earring -like tracts that guide the needles to the right spots. The patient or the same staff person should place the needles. Once the tracts are formed, special blunt needles are used to avoid cutting new tracts.Buttonhole cannulation is quick to do, less likely to infiltrate, and largely painless for the patient.

Answer:

Bypass Question 13: The blood pump segment is a durable, larger diameter section of the arterial blood tubing. It is a threaded through the roller mechanism of the blood pump.

Answer:

Blood tubing Question 14: The 2yr CCHT certification is offered by the Nephrology Nursing Certification Committee.

Answer:

Certified in Biomedical Nephrology Technology -CBNT Question 15: Clinical practice guidelines are the suggestions of experst to improve patient outcomes. The National Kidney Foundation - NKF - DOQITM giudelines were written by expert panels who reviewed many research studies. CMS often adopts guidelines and turns them into rules that clinics must follow or benchmarks for good care.

Answer:

Coefficient of Ultrafiltration

Question 16: The number of CFUs in a water or dialysate sample is a measure of the number of living bacteria.

Answer:

Complement Activation Question 17: A catheter is a plastic tube. In hemodialysis, a catheter can be placed in a large, central vein for short-term or long term access. In peritoneal dialysis, a catheter is placed in the abdoman or chest. It is used to infuse fresh dialysate into the periotoneum and drain used dialysate.

Answer:

Cation Question 18: An aneurysm is a ballooning or bulging of a weak spot in a blood vessel. Severe bleeding can occur if an anerurysm ruptures, so great care must be taken with a patient who has one. Aneurysms can occur if needles are placed too often into the small area of a fistula.

Answer:

Angioplasty

Question 19: Access

Answer:

An access -vascular access- is a route into the bloodstream that allows enough blood flow for hemodialysis. For permanent access, a surgeon connects a vein to an artery. This can be done directly

• fistula- or with a piece of synthetic tubing - graft. For short term access, a catheter may be placed in a

large central vein.Question 20: Capillaries are tiny blood vessels, where oxygenated blood crosses from arteries into veins. They are smaller than a human hair; blood cells must line up single file to pass through. Unlike arteries and veins, capillary walls are semipermeable. The walls let oxygen, nutrients, and waste products pass through. In the kidneys, each glomerulus is a ball of capillaries that filters out wastes from the blood.

Answer:

Carbon tank Question 21: This monitor checks the conductivity of dialysate to be sure it is correct. If the level is wrong, an alarm goes off and the machine goes into bypass mode so dialysate is sent to the drain.

Answer:

Congestive Heart Failure - CHF
