Question 4

Which of the following is a common electrolyte disturbance in chronic kidney disease that can lead to dangerous cardiac arrhythmias?

Accepted Answer

Hyperkalemia

Question 5

A patient with CKD develops weak bones and bone pain. Which pathophysiological mechanism best explains this finding?

Accepted Answer

Question 6

Which of the following is NOT a recommended management strategy during the renal insufficiency stage of CKD?

Accepted Answer

Increase protein intake to promote healing

Question 7

A patient with CKD is prescribed a new medication. What pharmacokinetic change should be considered?

Accepted Answer

Reduced drug excretion leading to increased risk of toxicity

Question 8

Which of the following is a postrenal cause of acute renal failure?

Accepted Answer

Bilateral ureteral obstruction

Question 9

Why is anemia a common complication in chronic kidney disease?

Question 13

A patient with CKD is found to have elevated phosphorus and low calcium levels. What hormone is likely to be elevated as a compensatory response?

Accepted Answer

Parathyroid hormone (PTH)

Question 14

Which treatment option is considered the best long-term solution for children with end-stage renal disease (ESRD)?

Accepted Answer

Kidney transplantation

Question 15

A patient with CKD is prescribed antacids. What complication should be monitored due to altered drug absorption?
