A patient asks the technician, "What does uremia
mean?" The technician's response should be based on
the understanding that uremia is
1. a decrease in the number of red blood cells.
2. an increase in the serum potassium level.
3. a decrease in urine output.
4. an increase of wastes in the blood - correct answersan increase of wastes in the blood
A central venous catheter may be used as a vascular
access when a
1. patient has a limb amputation.
2. patient has inadequate blood vessels in the limbs.
3. patient's dialysis adequacy needs to be reduced.
4. patient has an allergy to expanded
polytetrafluoroethylene (Gore-Tex). - correct answerspatient has inadequate blood vessels in the limbs.
Before a dialysis treatment, the patient tells the
technician, "Yesterday, I felt terrible and vomited up
some blood. I feel much better today." The technician
can expect the patient's treatment will be modified by
1. decreasing the heparin dose.
2. decreasing the blood flow.
3. increasing the dialysis flow rate.
4. increasing the ultrafiltration rate. - correct answersdecreasing the heparin dose.
The technician is unsure which one of a patient's
arteriovenous (AV) graft's anastomoses is arterial and
which one is venous. In order to differentiate between
the two, the technician should
1. cannulate both sides of the graft and check the
color of the blood.
2. apply a tourniquet to the arm and feel for venous
resistance.
, 3. compress the graft in the middle and palpate each
side.
4. determine the anatomical structure of the area and
palpate the radial pulse. - correct answerscompress the graft in the middle and palpate each
side.
At the end of a patient's treatment, which of these
findings, if observed by the technician, should be
reported to the nurse?
1. A pulse rate of 120 beats per minute.
2. Temperature of 98°F (36.3°C).
3. A weight loss of 6.6 lb (3 kg).
4. Blood pressure of 122/68 mm Hg. - correct answersA pulse rate of 120 beats per minute.
A patient asks the dialysis technician, "Why am I getting
vitamin D therapy?" Which of these responses would be
accurate?
1. "Vitamin D prevents infection."
2. "Vitamin D protects nervous tissue."
3. "Vitamin D is needed for healthy bones."
4. "Vitamin D stimulates production of red blood
cells." - correct answers"Vitamin D is needed for healthy bones."
Why are dialysis patients more likely to become infected
with germs like methicillin-resistant Staphylococcus
aureus (MRSA)?
1. Their diet is usually restricted in vitamin C.
2. They usually have weak immune systems.
3. Their kidneys cannot filter out toxins.
4. They often have allergies to most antibiotics. - correct answersThey usually have weak immune
systems.
Ivan Jackson, 63 years old, has been on in-center
hemodialysis for three years. Mr. Jackson's pre-dialysis
blood pressure is 133/92 mm Hg.
The technician prepares and cannulates Mr. Jackson's
arteriovenous (AV) fistula. An AV fistula is an example of
a
1. central venous access.
2. peripheral access.
3. temporary access.
4. woven polyester access. - correct answersperipheral access.
