Question 1

A home peritoneal dialysis patient reports that their dwell time has been shortened due to work. The nurse's priority concern is:

Accepted Answer

Inadequate solute clearance and underdialysis

Answer

Shortened dwell times reduce equilibration and solute clearance, leading to inadequate dialysis and uremic toxin accumulation.

Question 2

Which clinical finding most strongly suggests air embolism during hemodialysis?

Accepted Answer

Cyanosis, dyspnea, and millwheel murmur over the precordium

Answer

Air embolism classically presents with cyanosis, respiratory distress, and a churning millwheel murmur caused by air in the right heart.

Question 3

A patient's spKt/V result is 1.1. According to KDOQI guidelines, the appropriate nursing response is:

Accepted Answer

Notify the care team; the minimum target of 1.2 has not been achieved

Answer

KDOQI guidelines recommend a minimum spKt/V of 1.2 per treatment; a result of 1.1 falls below this threshold and requires intervention.

Question 4

A dialysis patient on warfarin for atrial fibrillation has an INR of 4.8 before treatment. The nurse should:

Accepted Answer

Notify the physician and withhold heparin during dialysis

Answer

A supratherapeutic INR increases bleeding risk; the physician should be notified and heparin withheld to minimize hemorrhagic complications during access cannulation.

Question 5

Which parameter best guides the adjustment of a peritoneal dialysis patient's dry weight (target weight)?

Accepted Answer

Clinical signs of fluid status: blood pressure, edema, and lung sounds

Answer

Dry weight in PD is determined clinically by assessing blood pressure, presence of edema, and auscultation for fluid in the lungs.
