Which of the following groups has the lowest risk for deveolping tb? - patients who are more than 10% above their dry weight Needles placed too close together in a vascular access can increase the chance of which of the following? - access recirculation In response to a machine high temperatue alarm the technician's first action should be to - verify that dialysate flow is stopped Individual patient response to heparin therapy can be monitored most accurately by - determination of activated partial thromboplastin During a hemodialysis treatment the blood in the dialyzer venous line and chamber becomes very dark. Which of the following conditions would the technician also likely observe? - an increase post pump arterial pressure With regard to the evaluation of a new piece of dialysis equipment, the least helpful resource is the - fda good manufacturing practice act The technician has tested the tap water for the total chlorine and the level is zero. The municipal water treatment plants tell the technician it does not use chorine. The technician had no carbon tanks on the water treatment system because of the potential for bacterial growth. Which of the following actions should the technician take? - stock carbon tanks or some appropriate chloring/chloramines treatment and test the water daily. When selecting a dialyzer for a hemodialysis patient, which of the following is least important - manufaturer High level of bacteria in the dialyzing fluid can cause major patient problems, including all of the following except. - cramps The substance secreted by the kidneys that causes hypertension in response to decreased blood flow is call - renin The destruction of red blood cells through a process in which the cell bursts with a resultant release of hemoglobin is called - hemolysis Which of the following substances is responsible for tubular reabsorption of calcium? - parathyroid hormone Which of the following laboratory values supports a diagnosis of hepatitis b infection? - hep b surface antigen(hbsag) Recirculation is the mixing of outflow blood with inflow blood leading to poor dialysis. All of the following condition will contribute to recirculation during dialysis except - placement of the arterial needle near and directed toward the anastmosis If there is a low arterial pressre(prepump) the technician should do which of the following? - check needle placement All of the following are potential problems associated with the use of bicarbonate dialysate except - precipitation of calcium and magnesium in the delivery system Heparin can be neutralized in the blood by which of the following compounds? - saline All of the following are relevant factors in ensuring the accuracy of the activated clotting time (act) except - patient's hematocrit value To communicate well through documentation, entries in the medical record should be clear - concise and timely Laboratory results show hypernatremia, which indicates - high sodium When a pyrogenic reaction occurs, the water treatment system should be cultured for - gram-negative bacteria In post-dialysis treatment, a needle may be left in place - to administer saline in the event of low blood pressure When protamine is infused into the venous line maintaining the patients normal clotting time during heparinization, the method of heparinization being used is - tight When the air detector alarm sounds, it should simultaneously perform which of the following functions? - clamp the venous line, give auditory and visual alarms and stop the blood pump It is important for members of the dialysis staff to be aware that the heart muscle is affected - abnormal serum potassium level A technician accidentally punctures her skin with a needle that was used on a patient who shows a negative reaction to hepatitis b surface antigen. This incident should be reported to the supervisor - immediately Labored and difficult breathing is called - dyspnea If a patient's body temperature above 100 f, the patient is said to be - febrile Proteinuria usually indicated damage to the - glomerulus Redness and hard swelling at the site of a mantoux test means that a person - was exposed to tb Which of the following action taken in the last hour of dialysis will minimized post-dialysis bleeding - the patient recieves no more heparin The technician notes that the patient had been ultrafiltrating poorly for severl treatment and still has uremic odor post dialysis. The most appropriate action would be - reevaluate the dialysis prescription and asess with the nurse The maximum allowance for interruption time when performing cpr is - 5 second with specific exception To determine appropriate ultrfiltration needs for a patient, it is necessary to perform a predialysis assessment of fluid status. Signs that are most likely symptoms found in people who are bedridden and are fluid overloaded are - sacral and periobital edema
