CHT Patient Assessment and Monitoring in Dialysis 2

Question 1

What does 'interdialytic weight gain' primarily reflect in a hemodialysis patient?

Accepted Answer

Fluid accumulated between dialysis sessions due to inability to excrete water

Answer

Interdialytic weight gain predominantly reflects fluid accumulation between sessions, since ESRD patients cannot excrete excess water through normal renal function.

Question 2

Which laboratory value serves as the primary indicator for assessing hemodialysis treatment adequacy?

Accepted Answer

Urea reduction ratio (URR) or Kt/V urea

Answer

URR and Kt/V measure urea clearance, which serves as the standard surrogate for overall uremic toxin removal and dialysis adequacy.

Question 3

During hemodialysis, which clinical presentation is most characteristic of an air embolism?

Accepted Answer

Sudden hypotension, dyspnea, cyanosis, and a mill-wheel cardiac murmur

Answer

Air embolism classically presents with sudden hypotension, dyspnea, cyanosis, and a characteristic mill-wheel murmur caused by air churning in the cardiac chambers.

Question 4

What is the generally recommended maximum ultrafiltration rate to reduce the risk of intradialytic hypotension?

Accepted Answer

Less than 13 mL/kg/hour

Answer

Current evidence-based guidelines recommend keeping ultrafiltration rates below 13 mL/kg/hour to minimize cardiovascular stress and intradialytic hypotension risk.

Question 5

After completing hemodialysis, a patient's post-treatment weight should ideally match which reference value?

Accepted Answer

The patient's established dry weight (target weight)

Answer

Post-dialysis weight should equal the patient's established dry weight, confirming that appropriate fluid removal was achieved without over- or under-ultrafiltration.
