This document contains the "Final Version" of DaVita test questions and answers, compiled
from multiple verified sources. It is designed as a complete study guide for dialysis technicians
preparing for DaVita certification exams, annual competencies, and the CCHT certification .
SECTION 1: DAVITA STAR LEARNING EXAM
Question 1.1
The primary electrolyte in both our blood and the dialysate is:
Answer: Sodium
Rationale: Sodium is the primary electrolyte in blood and dialysate, playing a crucial role in fluid
balance, nerve transmission, and muscle function. Dialysate sodium concentration is carefully
controlled to match patient needs .
, Question 1.2
Policy states the conductivity meter should be calibrated when an inaccurate reading is
suspected. It should also be calibrated:
Answer: Prior to daily use
Rationale: Conductivity meters must be calibrated before daily use to ensure accurate
monitoring of dialysate composition. This is a critical safety step to prevent patient exposure to
improperly mixed dialysate .
Question 1.3
When the dialysate sodium level is higher than the level in the blood:
Answer: Diffusion will cause sodium to move into the blood
Rationale: Diffusion is the movement of solutes from an area of higher concentration to lower
concentration. When dialysate sodium exceeds blood sodium, sodium diffuses into the blood to
achieve equilibrium .
Question 1.4
The calibration of the conductivity meter should be completed at least:
Answer: Daily
Rationale: Conductivity meter calibration must be performed at least daily to ensure ongoing
accuracy and patient safety throughout the treatment day .
Question 1.5
Hypernatremia can lead to:
Answer: Excessive thirst and decreased weight gains between treatments
Rationale: High sodium levels (hypernatremia) stimulate thirst as the body attempts to dilute the
blood. Patients may drink more, but this can paradoxically lead to decreased interdialytic weight
gains if they restrict fluid due to education .
