Free Certified Hemodialysis Technician Questions and Answers — Questions and Answers

Question 1: In the US, the following factors are the most typical causes of chronic kidney disease:

glomerulonephritis
polycystic kidney disease
diabetes (Correct answer)
hypertension

Correct answer: diabetes

The most frequent cause of chronic renal failure (CRF) in the US is diabetes mellitus. Future incidence of CRF may increase due to the rise in type 2 diabetes (which affects 90% of diabetic patients) brought on by the obesity epidemic. The most likely cause of diabetic nephropathy is endovascular injury to the renal arteries. The second most common factor causing CRF is hypertension. The so-called essential type, in which the precise reason is uncertain, predominates. In the first few years of this decade, kidney failure due to hypertension affected around 27% of dialysis patients. With its harmful effects, hypertension can also be brought on by renal disease or renal artery stenosis. Among other causes of CRF are glomerular illnesses polycystic illness, too. Cancer, kidney infections, AIDS, systemic lupus erythematosus, and sickle cell disease are less frequent causes of CRF.

Question 2: Which of the following conditions has the LOWEST CHANCE of being brought on by uremia?

anemia
urinary tract infection (Correct answer)
itching
edema (swelling) of the extremities

Correct answer: urinary tract infection

Itching, myalgias, dyspnea or edema from fluid retention, skin pallor or yellowish cast, foamy urine (due to protein), and nocturia are some of the typical symptoms of uremia. Uremia is the term used to describe a constellation of symptoms resulting from kidney failure, with a resulting buildup of waste products in the circulation (e.g., urea). The nephrotic syndrome is defined as a loss of protein in the urine greater than 3.5 g/d and may contribute to excessive fluid retention. These symptoms frequently appear gradually, thus it is advised to check on the patient frequently. Although hemodialysis may lessen uremic symptoms, it only replicates around 15% of normal kidney function. As a result, more frequent and prolonged if the symptoms continue, hemodialysis can be recommended. Uremia does not induce urinary tract infections; rather, bacteria are introduced.

Question 3: Chronic renal failure is accompanied by ALL OF THE FOLLOWING, EXCEPT:

hypoparathyroidism (Correct answer)
hyperkalemia
hyperphosphatemia
low hemoglobin

Correct answer: hypoparathyroidism

Chronic renal failure is characterized by a wide range of blood, protein, and electrolyte abnormalities. Due to recurrent blood loss, iron deficiency, and decreased erythropoietin secretion by the sick kidney, anemia is a relatively prevalent condition. Inadequate calcitriol impairs calcium absorption, while insufficient tubular excretion of phosphate causes high phosphate levels. The parathyroid gland is stimulated by a low calcium level to create more parathyroid hormone, resulting in secondary hyperparathyroidism. Calcium buildup in the heart and blood vessels could develop from this. These individuals frequently have elevated potassium levels, which could be fatal.

Question 4: How many kidneys are still functioning one year after transplantation?

30%
50%
70%
90% (Correct answer)

Correct answer: 90%

A common kind of treatment for chronic renal illness is kidney transplantation. In the US, about 15,000 are carried out annually. The kidney transplant recipient may get a living related donor (such as a spouse or friend) or a cadaver kidney, which is typically from a non-related person who just passed away. The patient is often matched from the national donor list in the latter scenario. In all situations, blood and tissue type (human leukocyte antigen) matching is crucial for the survival of the organ in the recipient, and living donors should be in good physical and mental health. Up to 20 years or longer may pass after a kidney transplant, almost invariably with the use of immunosuppressive medications that reduce the risk of rejection of disapproval. At one year after surgery, between 89% and 95% of transplanted kidneys are functioning.

Question 5: Which hemodialysis regimen is most likely to be effective?

Short daily home hemodialysis, 2–3 hours a session, 5–7 days a week (Correct answer)
Nocturnal home hemodialysis, 8 hours during sleep, 3 days a week
In-center hemodialysis, 3–4 hours a session, 3 days a week
Conventional home hemodialysis

Correct answer: Short daily home hemodialysis, 2–3 hours a session, 5–7 days a week

The majority of hemodialysis in the US is performed in centers, often over three days and three hours per session. The presence of nurses, technicians, and other patients gives the patient receiving treatment comfort. However, the time commitment could conflict with job schedules or childcare responsibilities. Some facilities provide hemodialysis at night while the patient stays overnight. Another option is to perform hemodialysis at home using dialyzers that are made specifically for this purpose. However, both the patient and their spouse or partner must receive training in proper technique, standard operating procedures, and an emergency action plan. Home hemodialysis performed at night provides for more time under treatment and has been demonstrated to alleviate several chronic renal disease symptoms. The most effective timetable is probably the one. The more recent, shorter daily home hemodialysis schedule—which typically lasts 2-3 hours per session, 5-7 days per week—is probably the most effective. The first two hours of dialysis are the most effective, and the shorter schedule gives patients more time for work and leisure pursuits.

Question 6: Most patients receiving in-center hemodialysis have a hydration restriction equivalent to urine volume/day plus:

1 L (Correct answer)
2 L
0 L
0.5 L

Correct answer: 1 L

Dialysis is required to eliminate extra fluid because individuals with end-stage renal failure have little to no urine output. The typical fluid replacement formula is the amount of urine the patient really produces plus so-called insensible losses (such as breathing, stools, and perspiration), or about 600 mL/d. An ordinary prescription would therefore be urine volume plus 1 L (4 cups) each day. Every patient's evaluation must pay close attention to dry weight (post-dialysis weight), indications of dehydration (such as thirst, weight loss, poor skin turgor, hypotension), or fluid overload (such as edema, pulmonary congestion, and hypertension). Dietary concerns are crucial because these patients frequently experience malnutrition and loss of appetite, therefore speaking with a dietician with experience in renal failure is highly recommended. Since these patients frequently experience loss of appetite and malnutrition, dietary concerns are crucial, and discussion with a dietician experienced in renal failure is frequently required.

Question 7: Patients with renal failure who fail to eliminate beta2-microglobulin are more likely to:

seizure
pericarditis
amyloidosis (Correct answer)
neuropathy

Correct answer: amyloidosis

A protein found in abundance in bodily fluids and on cell surfaces is called beta2-microglobulin. It is a protein that comes before the amyloid protein, which is created when beta2-microglobulin penetrates tissues and transforms into amyloid. Beta2-microglobulin is excreted by healthy kidneys, but when the kidneys are failing, levels rise, leading to a condition known as amyloidosis. Carpal tunnel syndrome, joint pain, bone cysts, compression fractures, and cutaneous bleeding could all result from this. After 10 years, over 20% of hemodialysis patients have amyloidosis, and after 29 years, 80%–100%. Peripheral neuropathy and pericarditis are frequent in chronic renal illness, both of which are most likely caused by insufficient excretion of neurotoxic chemicals. Seizures are possible but typically result from incorrect electrolytes, particularly hyponatremia.
