Free CCHT Patient and Family Education Questions and Answers 1 — Questions and Answers
Question 1: When educating a new patient about their arteriovenous (AV) fistula, what is the most important daily self-care check they should be taught to perform?
- Measure the circumference of their access arm daily
- Check their blood pressure in the access arm
- Feel for the 'thrill' and listen for the 'bruit' (Correct answer)
- Apply ice packs to the fistula after every treatment
Correct answer: Feel for the 'thrill' and listen for the 'bruit'
The 'thrill' (a palpable vibration) and the 'bruit' (an audible whooshing sound) are signs of good blood flow through the fistula. Teaching the patient to check for these daily helps in the early detection of potential problems like clotting or stenosis, which could lead to access failure.
Question 2: A patient on hemodialysis should be educated to contact the clinic immediately if they experience which of the following symptoms?
- Mild fatigue after treatment
- Fever and chills (Correct answer)
- A small amount of bruising at the needle site
- Feeling thirsty between treatments
Correct answer: Fever and chills
Fever and chills are classic signs of infection, which can be life-threatening for a dialysis patient. An infection could be related to their vascular access (an access infection) or systemic, and it requires immediate medical evaluation and treatment.
Question 3: What is the primary reason for fluid restrictions for most hemodialysis patients?
- To make the dialysis treatment shorter
- To prevent the dialyzer from clotting
- To prevent large fluid gains between treatments, which can strain the heart (Correct answer)
- To reduce the amount of urine they produce
Correct answer: To prevent large fluid gains between treatments, which can strain the heart
Since the kidneys are no longer able to remove excess fluid, it accumulates in the body between dialysis sessions. Large fluid gains lead to high blood pressure, shortness of breath, and significant strain on the cardiovascular system, increasing the risk of heart failure.
Question 4: When teaching a patient about a renal diet, which three minerals are typically the most important to restrict?
- Iron, calcium, and zinc
- Sodium, potassium, and phosphorus (Correct answer)
- Magnesium, chloride, and iron
- Calcium, potassium, and vitamin D
Correct answer: Sodium, potassium, and phosphorus
A renal diet is designed to limit the buildup of waste products and electrolytes that the kidneys can no longer filter effectively. Sodium can cause fluid retention and high blood pressure, high potassium can lead to dangerous heart rhythms, and high phosphorus can cause bone disease.
Question 5: A patient asks why they cannot use lotion on their access site on the day of treatment. What is the best explanation?
- It can make the skin too slippery for the needles
- It will cause the access to clot
- It can cause a severe allergic reaction with the dialyzer
- Lotions can interfere with proper site cleaning and increase infection risk (Correct answer)
Correct answer: Lotions can interfere with proper site cleaning and increase infection risk
Proper disinfection of the cannulation sites is critical to prevent access-related infections. Lotions and creams can create a barrier that prevents the antiseptic from effectively killing bacteria on the skin, and they can also be introduced into the bloodstream during cannulation.
Question 6: When explaining the concept of 'dry weight' to a patient, which description is most accurate?
- The patient's weight before starting dialysis for the first time
- The maximum weight a patient is allowed to gain between treatments
- The patient's weight without any excess fluid, at which their blood pressure is normal (Correct answer)
- The weight of the dialyzer and blood lines
Correct answer: The patient's weight without any excess fluid, at which their blood pressure is normal
Dry weight is the target weight to be achieved at the end of a dialysis treatment. It represents the patient's estimated normal body weight without the extra fluid that accumulates due to kidney failure. At this weight, the patient should not be hypotensive or have signs of fluid overload like edema or shortness of breath.
Question 7: A patient should be taught that which of the following activities should be avoided in their access arm?
- Having their blood pressure taken (Correct answer)
- Performing light exercises like squeezing a ball
- Gently washing the arm with soap and water
- Elevating the arm on a pillow
Correct answer: Having their blood pressure taken
To protect the vascular access, patients should be taught to avoid anything that could compress the blood vessels and cause clotting or damage. This includes having blood pressure taken, wearing tight clothing or jewelry, and having blood drawn from that arm for routine lab work.
