Introduction
This comprehensive assessment is designed to prepare registered nurses for the DaVita RN Final Examination. It
rigorously evaluates the essential knowledge, clinical judgment, and practical skills required for safe and effective
nephrology nursing practice. The exam encompasses a wide range of topics, including the principles of hemodialysis,
vascular access care, management of fluid and electrolyte imbalances, and the recognition and treatment of
intradialytic complications. Candidates will encounter a variety of multiple-choice questions, from foundational
knowledge to complex, real-world scenarios that test critical thinking and professional decision-making. Mastery of this
material is crucial for ensuring high-quality patient care, adherence to regulatory standards, and successful completion
of the certification process.
Question 1
A patient receiving hemodialysis complains of a sudden onset of headache, nausea, and confusion. Which of the
,following complications is the most likely cause of these symptoms?
A. Air embolism
B. Dialysis disequilibrium syndrome
C. Hemolysis
D. Pyrogenic reaction
🟢 Correct Answer: B. Dialysis disequilibrium syndrome
🔴 Explanation: Dialysis disequilibrium syndrome is characterized by neurological symptoms such as headache,
nausea, vomiting, confusion, and restlessness. It is thought to be caused by a rapid shift in osmolality and cerebral
edema, particularly in patients new to dialysis. Air embolism would present with respiratory distress and chest pain,
while hemolysis would show with "cherry-red" blood and hypotension. A pyrogenic reaction typically presents with
fever and chills.
Question 2
What is the acceptable limit for total chlorine in the water leaving the carbon filter?
A. 0.1 mg/L or less
B. 0.5 mg/L or less
C. 1.0 mg/L or less
D. 5.0 mg/L or less
🟢 Correct Answer: A. 0.1 mg/L or less
🔴 Explanation: The acceptable limit for total chlorine in the water leaving the carbon filter is 0.1 mg/L or less . This
is a critical safety parameter, as chlorine is toxic to patients and can cause hemolysis. Water quality tests are
performed to ensure this limit is not exceeded.
Question 3
A patient is undergoing hemodialysis and experiences a sudden drop in blood pressure. In what position should the
nurse place the patient to manage this intradialytic hypotension?
A. High Fowler's position
,B. Left lateral Trendelenburg position
C. Supine position
D. Trendelenburg position
🟢 Correct Answer: D. Trendelenburg position
🔴 Explanation: Placing the patient in the Trendelenburg position (supine with feet elevated) is the initial
intervention for intradialytic hypotension. This position promotes venous return and helps to restore blood
pressure . High Fowler's would worsen hypotension, and the left lateral position is specific to air embolism.
Question 4
During a hemodialysis treatment, the venous pressure alarm sounds. This alarm most likely indicates a problem with
the:
A. Blood flow from the patient to the dialyzer
B. Blood return from the dialyzer to the patient
C. Dialysate flow rate
D. Ultrafiltration rate
🟢 Correct Answer: B. Blood return from the dialyzer to the patient
🔴 Explanation: The venous pressure alarm monitors the pressure in the venous (return) line. An increase in venous
pressure may indicate a kink in the line, a clot in the venous drip chamber, or a problem with the vascular access,
while a decrease could signal a disconnect or needle infiltration.
Question 5
Which of the following actions is an independent nursing function?
A. Administering a PRN dose of a prescribed antiemetic
B. Adjusting a patient's dry weight based on physical assessment
C. Performing patient education on dietary restrictions
D. Starting a patient on a new antibiotic
🟢 Correct Answer: C. Performing patient education on dietary restrictions
, 🔴 Explanation: Independent nursing functions are those that a nurse can perform independently, based on their
own knowledge and skill, without a physician's order. Patient education is a key independent nursing function .
Administering medications and adjusting dry weight (a medical prescription) are dependent or interdependent
functions.
Question 6
A patient's laboratory results show a serum potassium level of 6.8 mEq/L. Which of the following is the priority
nursing action?
A. Assess the patient's EKG for peaked T-waves
B. Notify the provider immediately
C. Prepare to administer oral Kayexalate
D. Reassure the patient that this is a normal finding
🟢 Correct Answer: A. Assess the patient's EKG for peaked T-waves
🔴 Explanation: Hyperkalemia (K+ > 5.0 mEq/L) is a life-threatening electrolyte imbalance. The priority nursing
action is to assess the patient's cardiac status, as peaked T-waves are an early EKG change. While notifying the
provider and preparing for treatment are important, the initial and most immediate action is to assess for life-
threatening complications.
Question 7
The "Reasonable and Prudent" standard of care for nephrology nursing includes:
A. Only the actions a nurse would give under similar circumstances
B. Only the actions a nurse would avoid doing
C. Both the actions a reasonable nurse would do and the actions a nurse would avoid doing
D. Following hospital policies and procedures without deviation
🟢 Correct Answer: C. Both the actions a reasonable nurse would do and the actions a nurse would avoid doing
🔴 Explanation: The "Reasonable and Prudent" standard defines the minimum level of care expected of a competent
