CCHT Medication Administration and Anticoagulation 2

Question 1

A hemodialysis patient receives intravenous sodium bicarbonate during treatment. What is the primary indication for this medication?

Accepted Answer

Metabolic acidosis

Answer

IV sodium bicarbonate is administered to correct metabolic acidosis, which is common in end-stage renal disease patients.

Question 2

Which phosphate binder is commonly administered with meals to dialysis patients to control serum phosphorus levels?

Accepted Answer

Calcium carbonate or sevelamer

Answer

Calcium carbonate and sevelamer are commonly used phosphate binders taken with meals to reduce phosphorus absorption from food.

Question 3

When using a continuous heparin infusion during dialysis, what laboratory test is used to monitor anticoagulation levels?

Accepted Answer

Activated clotting time (ACT) or APTT

Answer

The activated clotting time (ACT) or activated partial thromboplastin time (APTT) is used to monitor heparin anticoagulation during dialysis.

Question 4

A patient on hemodialysis develops heparin-induced thrombocytopenia (HIT). Which finding on laboratory results would support this diagnosis?

Accepted Answer

Platelet count drop of >50% from baseline

Answer

HIT is characterized by a significant drop in platelet count (>50% from baseline) occurring 5–10 days after heparin initiation due to antibody formation.

Question 5

What is the purpose of administering vitamin D analogs (e.g., calcitriol) to hemodialysis patients?

Accepted Answer

Suppress secondary hyperparathyroidism and manage bone disease

Answer

Active vitamin D analogs suppress parathyroid hormone (PTH) secretion to manage secondary hyperparathyroidism and renal osteodystrophy in dialysis patients.
