Question 1

Peritoneal dialysis (PD) differs from hemodialysis in which of the following ways?

Accepted Answer

PD access is by an intra-abdominal catheter

Answer

Peritoneal dialysis (PD) utilizes the peritoneum, a membrane lining the abdominal cavity, as a natural filter. To access this cavity, a permanent catheter is surgically placed into the abdomen. This allows dialysate fluid to be introduced and drained, facilitating waste removal within the patient's own body.

Question 2

The most likely cause of post-renal failure is:

Accepted Answer

benign prostatic hypertrophy.

Answer

Post-renal failure occurs when there is an obstruction in the urinary tract that prevents urine flow out of the kidneys. Benign prostatic hypertrophy (BPH) is a common condition in older men where the prostate gland enlarges, compressing the urethra and blocking urine outflow, thus leading to post-renal acute kidney injury.

Question 3

The most common cause of chronic kidney disease in the United States is:

Accepted Answer

diabetes.

Answer

Diabetes is the leading cause of chronic kidney disease (CKD) in the United States, accounting for nearly half of all cases. High blood sugar levels over time damage the small blood vessels in the kidneys, impairing their ability to filter waste. This damage can progressively lead to kidney failure.

Question 4

Which of the following conditions is LEAST likely to be caused by uremia?

Accepted Answer

Urinary tract infection

Answer

Uremia refers to the accumulation of waste products in the blood due to kidney failure. While uremia causes symptoms like itching, edema, and anemia, it does not directly cause urinary tract infections (UTIs). UTIs are typically caused by bacterial invasion of the urinary tract, often unrelated to the systemic effects of uremia.

Question 5

All of the following conditions are associated with chronic kidney failure EXCEPT:

Accepted Answer

hypoparathyroidism.

Answer

Chronic kidney failure often leads to hyperparathyroidism, not hypoparathyroidism. Damaged kidneys cannot properly activate Vitamin D, leading to low calcium levels, which in turn stimulates the parathyroid glands to overproduce parathyroid hormone (PTH) in an attempt to raise calcium. This condition is known as secondary hyperparathyroidism.
