Free Hemodialysis Technologist Questions and Answers — Questions and Answers
Question 1: Which of the following describes how hemodialysis and peritoneal dialysis (PD) are different?
- PD access is by an intra-abdominal catheter (Correct answer)
- Sterile dialysate is not required for PD
- Peritoneal dialysis (PD) differs from hemodialysis in which of the following ways?
- PD requires both vascular and abdominal access
Correct answer: PD access is by an intra-abdominal catheter
Since the blood goes from the patient through the semipermeable membrane of the dialysis machine and then back into the patient, hemodialysis <br> necessitates vascular access.
Question 2: An arteriovenous shunt (AVS) and an arteriovenous fistula (AVF) vary primarily by having an?
- AVF requires an external tube
- AVS is entirely within the arm
- AVF is entirely within the arm (Correct answer)
- AVF is more likely to become clotted or infected
Correct answer: AVF is entirely within the arm
Repeated vascular access is necessary because hemodialysis must be performed repeatedly, typically three times a week for four hours.
Question 3: Which dialyzer from the list below is in use right now?
- coil
- hollow tube (Correct answer)
- kill
- flat plate
Correct answer: hollow tube
Since they were first used often in the 1960s, dialysis machines have undergone changes.
Question 4: Which of the following skeletal structures attaches to the ureter and directly transports urine there?
- calyx
- glomerulus
- cortex
- pelvis (Correct answer)
Correct answer: pelvis
The kidney is a bilateral organ about the size of a fist with a hard outer capsule.
Question 5: An essential indicator of renal function is the glomerular filtration rate, which in a healthy adult is roughly?
- 125 mL/min/1.73 m2 (Correct answer)
- 200 mL/min/1.73 m2
- 50 mL/min/1.73 m2
- 75 mL/min/1.73 m2
Correct answer: 125 mL/min/1.73 m2
The glomerular filtration rate (GRF) of an adult is typically around 125 mL/min, though there may be considerable variation depending on age and sex.
Question 6: The kidneys create each and every one of the following, but which one?
- calcitriol
- renin
- aldosterone (Correct answer)
- erythropoietin
Correct answer: aldosterone
The kidney is unable to produce aldosterone.
Question 7: What is the most probable reason for post-renal failure?
- glomerulonephritis
- benign prostatic hypertrophy (Correct answer)
- severe dehydration
- nephrotoxic drug
Correct answer: benign prostatic hypertrophy
The anatomic site of the injury is frequently used to categorize acute renal failure (ARF). Pre-renal failure is frequently brought on by hypotension, <br> which happens when there has been trauma, dehydration, or blood loss and the renal blood flow has been significantly reduced.
