Abscess - CORRECT>>> An abscess is an infection under the skin. It looks lika blister or pimple filled
with fluid or pus. If needles are inserted into or near an abscess, infection of a dialysis access or other
tissues may occur.
Access - CORRECT>>> 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. - correct answer
Acid - CORRECT>>> An acid is substance with a pH below 7.0 that can donate a hydrogen ion -H+. Inthe
human body, acids form when protein and other foods are broken down by cell metabolism.
Acquired Immunodeficiency Syndrome - AIDS - correct answer
Acute Kidney Failure - CORRECT>>> Acute kidney failure has a sudden onset. It is most often caused byan
illness, injury, or toxin that stresses the kidneys. Some patients who survive acute kidney failure can
recover kidney function. Others die or go on to develop chronic kidney failure.
Alum - CORRECT>>> Alum is an aluminum compound. It is often added to city water supplies toremove
sediment and make the water clearer.
Aluminum can build up in the bodies and brains of dialysis patients. Aluminum in dialysis water must be
kept at low levels with water treatment. - correct answer
,Aluminum-Related Bone Disease - ARBD - CORRECT>>> ARBD is cause by long-term exposure to
aluminum. Aluminum builds up in the tissues at the point where new bone forms and be seen on X-ray.
Sources of aluminum include dialysis water, medications, and cookware.
,Phosphate binders with aluminum are also a source, but these are rarely used today. Symptoms of ARBD
can include deep bone pain, muscle weakness, and fractures. - correct answer
Amyloidosis - CORRECT>>> Amyloidosis occurs when aproteingcalled beta-2-microglobulin -B2M-
builds up in soft tissues, bones, and joints. The deposits can cause joint and or bone pain. High-flux
membranes and or noctournal hemodialysis remove more B2M, which may help prevent or treat this
problem.
Anaphylaxis - CORRECT>>> Anaphylaxis is a fast severe immune response to an allergen. Hives, itching,or
wheezing may occur. Anaphylactic shock may cause blood pressure drop; change in heart rhythms or
arrest; and swelling of the lips, tongue, and throat. This problem can be fatal.
Anastomosis - CORRECT>>> An anastomosis is a surgical connection beteen two blood vessels. Dialysis
needles should not be inserted into the area of the anastomosis in a fistual or graft.
Adsorb - CORRECT>>> Adsorb means to attract and hold. The dialyzer membrane adsorbs blood
proteins to the walls of the hollow fibers during a treatment.
This can make reused dialyzers more biocompatible than new ones - if bleach is not used to remove the
protein coating. - correct answer
Advance Directives - CORRECT>>> Advance directives outline a patient's wishes for medical treatmentin
case he or she becomes too ill to make such choices. A living will is one type of advance directive.
The patient's family and other members of the care team should be told of the patient's wishes when an
advance directive is done and given a copy to keep. - correct answer
Afferent - CORRECT>>> means toward an organ.
Air Detector - CORRECT>>> The air - or foam detector checks blood in the venous line of the
extracorporeal circuit for air. Air in a patient's bloodstream can stop the blood flow or heartbeat, causing
death.
, If the detector finds air, an alarm will sound, the blood pump will stop, and the venous bloodline will
clamp to keep air from reaching the patient. - correct answer
Air Embolism - CORRECT>>> An air embolism occurs when air bubbles enter the bloodstream and flow
into a vessel small enough to be blocked by the air. The air in the vessel acts like a clot, blocking the flow
of blood.
Dialysis machines have an air detector on the venous bloodline to help prevent this problem, which can
be fatal. - correct answer
Albumin - CORRECT>>> Albumin is a blood protein. Lo serum albumin levels -<3.5 g/dL- may mean a
patient is undernourished. Malnutrition is a common in dialysis patients and raises their risk of death.
Anemia - CORRECT>>> Anemia is a shortage of oxygen-carrying red blood cells. It causes sever fatigue,
trouble with metal focus, reduced immune function, and many other problems.
Anemia is common in kidney failure due to less erythropoietin, iron deficiency, and loss of blood through
tests and dialysis itself. - correct answer
Anesthetic - CORRECT>>> An anesthetic is a drug that numbs the body to reduce pain. Local
anesthetics can be injected into a spot, such as the skin around a puncture site, before needle
placement. Or, gels or creams can be put on the skin to prevent pain at that site.
Aneurysm - CORRECT>>> 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.
Angioplasty - CORRECT>>> Angioplasty is a procedure to open a narrowed blood vessel - stenosis. It
may be used for vascular access repair. A small balloon is threaded through the vessel into the access
and gently inflated to push the walls of the vessel open.
Anion - CORRECT>>> An anion is a negatively-charged ion.
