Q1: According to DaVita's Core Values, which value emphasizes that "we are stewards
of our patients' health, our company's resources, and our environment"?
A. Service Excellence
B. Integrity
C. Stewardship [CORRECT]
D. Continuous Improvement
Correct Answer: C
Rationale: Stewardship is the DaVita Core Value that specifically emphasizes
responsible management of patient health, company resources, and environmental
impact. Service Excellence (A) focuses on exceeding expectations in patient care.
Integrity (B) relates to honesty and ethical behavior. Continuous Improvement (D)
,emphasizes ongoing enhancement of processes and outcomes. The DaVita Village
operates on these core values to guide all clinical and business decisions.
Q2: A patient arrives for dialysis with a 4.2 kg interdialytic weight gain (IDWG) over 2
days. The prescribed treatment time is 4 hours. What is the required ultrafiltration rate
(UFR) in mL/hr?
A. 850 mL/hr
B. 1,050 mL/hr [CORRECT]
C. 1,250 mL/hr
D. 1,500 mL/hr
Correct Answer: B
Rationale: Calculation: 4.2 kg = 4,200 mL (1 kg = 1,000 mL). UFR = Total fluid removal ÷
Treatment time = 4,200 mL ÷ 4 hours = 1,050 mL/hr. Option A (850 mL/hr) would be
insufficient for the prescribed fluid removal. Option C (1,250 mL/hr) and D (1,500 mL/hr)
would exceed the required rate and could cause hemodynamic instability. DaVita
protocols generally recommend keeping UFR <13 mL/kg/hr to minimize intradialytic
hypotension risk.
,Q3: Which of the following is the PRIMARY mechanism by which solutes are removed
during hemodialysis?
A. Ultrafiltration
B. Osmosis
C. Diffusion [CORRECT]
D. Convection
Correct Answer: C
Rationale: Diffusion is the primary mechanism for solute removal in hemodialysis,
driven by the concentration gradient between blood and dialysate across the
semipermeable membrane. Small molecules (urea, creatinine, potassium) move from
high to low concentration. Ultrafiltration (A) removes fluid via hydrostatic pressure.
Osmosis (B) involves water movement across membranes. Convection (D) contributes
to middle molecule removal but is secondary to diffusion for small solutes.
Understanding these principles is essential for DaVita PCTs managing treatment
prescriptions.
Q4: During water treatment system monitoring, the PCT notes chloramine levels at 0.15
mg/L. According to AAMI standards, what is the appropriate action?
A. Continue treatment; levels are within acceptable range
, B. Increase dialysate flow rate to dilute chloramines
C. Immediately stop dialysis and notify biomedical engineering [CORRECT]
D. Document and recheck in 30 minutes
Correct Answer: C
Rationale: AAMI standards require chloramine levels <0.1 mg/L (total chlorine). At 0.15
mg/L, dialysis must STOP immediately as chloramines cause hemolytic anemia and
methemoglobinemia. Option A is dangerous as levels exceed safe limits. Option B is
ineffective and dangerous. Option D delays critical intervention. DaVita requires
immediate notification of biomedical engineering and the charge nurse. Carbon tanks
must be evaluated for exhaustion.
Q5: A patient with an AV fistula in the left upper extremity presents with a weak thrill and
absent bruit. The hand is cool and pale. These findings are consistent with:
A. Infection
B. Steal syndrome [CORRECT]
C. Aneurysm formation
D. Normal maturation
