a. CRRT is more likely to induce dialysis-associated increase in intracranial pressure
b. CRRT is associated with less hemodynamic changes during treatment
c. CRRT allows for earlier mobilization of patients
d. CRRT is less efficient in removing solutes and fluid

Question 2#Print Question

A 44-year-old male with a long-standing history of insulindependent diabetes mellitus is admitted to the intensive care unit (ICU) with diabetic ketoacidosis. He has acute kidney injury (AKI) and is being started on hemodialysis in the ICU.

Which of the following is the LEAST preferred route for vascular access insertion for renal replacement therapy (RRT)?

a. Right internal jugular vein
b. Left internal jugular vein
c. Femoral vein
d. Subclavian vein

Question 3#Print Question

Which of the following techniques does hemodialysis employ for solute clearance?

a. Diffusion
b. Convection
c. Osmosis
d. Both diffusion and convection

Question 4#Print Question

A 63-year-old female has been admitted to the ICU from another hospital with ongoing acute upper gastrointestinal bleeding, necessitating multiple blood transfusions. She has a history of a previous coronary artery bypass grafting and end-stage renal disease (ESRD) on dialysis. The records from the other hospital indicate that she was recently diagnosed with heparin-induced thrombocytopenia (HIT). She is due to get her dialysis today and feels short of breath after the blood transfusions.

Which of the following is the MOST ideal anticoagulation strategy for hemodialysis in this patient?

a. Low–molecular weight heparin can be safely used in the circuit
b. Regional citrate anticoagulation
c. Dabigatran can be used
d. Dialysis cannot be safely performed at this time and needs to be deferred

Question 5#Print Question

In which of the following clinical scenarios is RRT LEAST likely to be urgently initiated?

a. 30-year-old female with postoperative acute renal insufficiency with serum magnesium >8 mEq/L with anuria and absent deep tendon reflexes
b. 50-year-old male with ESRD, on scheduled MWF dialysis, with serum potassium of 6 mEq/L
c. 45-year-old male with septic shock and anuric AKI on pressors with a PH of 7.0 and bicarbonate of 12 mEq/L
d. 60-year-old female with acute oliguric renal failure not responding to diuretic therapy with hypoxia and shortness of breath
