Question 1 of 5
What is the rational for administering calcium carbonate to a client with chronic renal failure?
Correct Answer: D
Rationale: Calcium carbonate is a phosphate binder that reduces phosphorus absorption from food, addressing hyperphosphatemia in chronic renal failure.
Question 2 of 5
Which intervention does the nurse utilize post-operatively to assess the patency of the arteriovenous fistula?
Correct Answer: B
Rationale: A functional AV fistula should have a palpable thrill (vibration) and an audible bruit (whooshing sound) when auscultated with a stethoscope. These findings confirm adequate blood flow and patency.
Question 3 of 5
The nurse is teaching the client with hypernatremia about dietary restrictions. Which foods would the nurse tell them to avoid?
Correct Answer: B
Rationale: Cheese, lunch meats, and canned vegetables are high in sodium, worsening hypernatremia.

The nurse is caring for a client who has chronic renal disease and is receiving therapy with erythropoietin (epoetin alpha). Which of the following laboratory results should the nurse review as an indication of a therapeutic effect of this medication?
Correct Answer: B
Rationale: Erythropoietin stimulates red blood cell production, increasing hemoglobin levels in clients with CKD-related anemia.
