FRESENIUS DIALYSIS EXAM 2024 QUESTIONS WITH COMPLETE ANSWERS

Dialysate is kept in the temperature range of... - CORRECT ANSWER 34.5-36.5°C Too warm dialysate can... - CORRECT ANSWER Cause the patient's RBC's to burst (hemolysis), as well as, cause hyperthermia. Too cold dialysate can.. - CORRECT ANSWER Cause the patient's to feel cold and less diffusion of dialysate will occur. However, slightly cool dialysate can help prevent deadly hypotension and organ stunning due to the constriction of blood vessels. Conductivity definition - CORRECT ANSWER How well fluid conducts an electrical charge (should be isotonic). Theoretical conductivity (TCD) - CORRECT ANSWER Based on the prescription. Should be close to the actual (+/- 0.5) Low conductivity can cause... - CORRECT ANSWER Is diverted to drain too much H2O. Can cause RBC rupture which increases K+, and pt can have s/s of hypoxia due to hemolysis. High conductivity can cause... - CORRECT ANSWER Hypertonic solution where there is too little H2O...H2O is leaving the cell to dilute sodium content outside the cell (crenation). pH definition - CORRECT ANSWER Hydrogen ion concentration of a solution.
