Dialysis Quiz
Questions: 16 · 10 minutes
1. A person notices new redness, warmth, tenderness, and drainage around a dialysis access site. What is the most appropriate response?
Cover the area tightly and continue treatment without mentioning it
Wait until the next monthly appointment unless the access stops working
Contact the dialysis team promptly because these may be signs of infection
Apply a nonprescribed cream and reassess after several days
2. What is a primary purpose of dialysis when the kidneys can no longer perform adequately?
To increase urine production by directly stimulating the bladder
To repair damaged kidney tissue so normal filtration resumes immediately
To remove certain wastes and excess fluid while helping control electrolyte and acid-base balance
To replace every hormonal and metabolic function of healthy kidneys
3. During hemodialysis, a person becomes dizzy and develops muscle cramps after fluid has been removed. Which explanation is most plausible?
The kidneys have suddenly returned to full function
Blood pressure may have fallen as fluid was removed
The vascular access has necessarily developed an infection
The dialyzer has increased the person's blood volume
4. After missing dialysis, a person develops marked weakness and an irregular or pounding heartbeat. Which dialysis-related concern is particularly important to assess urgently?
Low phosphorus caused by one missed treatment
A potentially dangerous potassium imbalance
Excess red blood cell production
A rapid increase in kidney hormone production
5. A person using peritoneal dialysis has cloudy drained fluid along with abdominal pain. What should this combination suggest?
A normal sign that the dialysis solution removed extra protein
Proof that the prescribed dwell time was too short
Possible peritonitis requiring prompt contact with the dialysis team
Expected irritation that should resolve after several exchanges
6. Why is anemia common among people with advanced chronic kidney disease, including many receiving dialysis?
Dialysis causes the lungs to absorb less oxygen from the air
Damaged kidneys may produce less erythropoietin, which supports red blood cell production
Healthy kidneys normally store the body's supply of iron
The peritoneal membrane destroys all newly formed red blood cells
7. A person who recently missed dialysis now has severe shortness of breath and chest discomfort. What should they do?
Seek urgent medical help rather than relying on a quiz or routine appointment
Wait for the next scheduled session and limit activity
Drink extra fluid to improve circulation before calling anyone
Take an additional dose of any available medicine
8. A clinician is preparing to take blood pressure on an arm containing a functioning arteriovenous fistula. What is generally the better approach?
Use that arm because cuff pressure tests whether the fistula is strong
Place the cuff directly over the fistula for the clearest reading
Temporarily compress the fistula before inflating the cuff
Use the other arm when possible to avoid pressure on the access
9. Which description best matches peritoneal dialysis?
Blood is continuously circulated through an external dialyzer
A machine filters urine after it leaves the bladder
Dialysis solution in the abdomen uses the peritoneal membrane for exchange
A transplanted tissue patch filters blood inside a vein
10. A hemodialysis patient's weight is higher before one session than it was immediately after the previous session. What does that increase most commonly help estimate?
Fluid accumulated between treatments
New muscle tissue produced between treatments
The amount of waste permanently stored in bone
How much blood the dialyzer will remove
11. A person receiving dialysis wants to start a new over-the-counter medicine. What is the soundest general step?
Use the standard package dose because dialysis removes every medicine evenly
Take it only on dialysis days so it cannot accumulate
Avoid all over-the-counter products permanently, regardless of their contents
Check with the renal care team or a pharmacist because dosing and ingredients may require review
12. Which healthy-kidney function is least directly replaced by routine dialysis?
Producing hormones involved in red blood cell production
Removing some dissolved waste products from the blood
Removing excess fluid from the body
Helping correct certain electrolyte and acid-base imbalances
13. Someone on dialysis has been advised to watch for phosphorus additives in packaged foods. Which label clue is most relevant?
Ingredients containing the word “fiber”
Ingredients containing “phos,” such as phosphate
Ingredients ending in “vitamin”
Ingredients identifying unsaturated oils
14. For many suitable patients who need long-term hemodialysis, which vascular access is generally favored because it can be durable and has a lower infection risk than a catheter?
A peripheral intravenous cannula
A urinary catheter
A central venous dialysis catheter
An arteriovenous fistula
15. During a peritoneal dialysis exchange, a connection is accidentally touched in a way that may have contaminated it. What is the best general response?
Continue normally because dialysate prevents bacterial growth
Rinse the connection with tap water and reconnect it
Shorten the next dwell to compensate for the contamination
Follow the trained contamination procedure and contact the dialysis team for guidance
16. How does hemodialysis primarily clean the blood?
Blood passes through a dialyzer outside the body and then returns
Dialysis fluid is placed in the abdomen and later drained
Medication inside the bloodstream permanently binds every waste product
The liver temporarily takes over filtration during each session
