Section 1: End-Stage Renal Disease Fundamentals (Questions 1-20)
Question 1
The nurse is caring for a client with end-stage renal disease (ESRD). Which statement best describes the
pathophysiology of ESRD?
A. The kidneys suddenly stop functioning due to acute injury
B. Progressive and irreversible loss of kidney function over time
C. Temporary kidney dysfunction that resolves with treatment
D. Inflammation of the kidneys that responds to antibiotics
Correct ANSWER✨✨✔-: B
Rationale for Option A: Incorrect. Acute kidney injury (AKI) involves sudden loss of kidney function,
which is different from ESRD. ESRD is a chronic, progressive condition that develops over months to
years, not suddenly.
www.ncbi.nlm.nih.gov
Rationale for Option B: Correct. ESRD is characterized by progressive and irreversible loss of kidney
function, typically when kidney function declines to less than 10-15% of normal. At this stage, dialysis or
kidney transplantation is necessary for survival.
www.ncbi.nlm.nih.gov
Rationale for Option C: Incorrect. ESRD is permanent and irreversible. Unlike acute kidney injury or some
forms of acute glomerulonephritis, ESRD does not resolve with treatment. Patients require lifelong
dialysis or transplantation.
www.kidney.org
Rationale for Option D: Incorrect. While some kidney diseases involve inflammation (such as
pyelonephritis or glomerulonephritis), ESRD itself is not primarily an inflammatory condition that
responds to antibiotics. ESRD represents end-stage damage from various causes.

Question 2
A client with ESRD asks the nurse about the normal function of healthy kidneys. Which function should
the nurse include in the explanation?
A. Production of insulin for glucose metabolism
B. Filtration of waste products and regulation of fluid balance
C. Synthesis of clotting factors for hemostasis
D. Storage of bile for digestion
Correct ANSWER✨✨✔-: B
Rationale for Option A: Incorrect. Insulin is produced by the beta cells of the pancreas, not the kidneys.
While kidneys do play a role in glucose metabolism through gluconeogenesis, they do not produce
insulin.
nurseslabs.com
Rationale for Option B: Correct. The kidneys' primary functions include filtering waste products (such as
urea, creatinine, and uric acid) from the blood, regulating fluid and electrolyte balance, maintaining
acid-base balance, and regulating blood pressure. These functions are lost in ESRD.
www.ncbi.nlm.nih.gov
Rationale for Option C: Incorrect. Clotting factors are primarily synthesized by the liver, not the kidneys.
The kidneys do produce erythropoietin (which stimulates red blood cell production) but not clotting
factors.
nurseslabs.com
Rationale for Option D: Incorrect. Bile is produced by the liver and stored in the gallbladder, not the
kidneys. This is a digestive system function unrelated to renal physiology.

Question 3
The nurse is reviewing laboratory results for a client with ESRD. Which finding is most consistent with
this diagnosis?
A. Creatinine level of 0.8 mg/dL
B. Glomerular filtration rate (GFR) of 85 mL/min
C. Blood urea nitrogen (BUN) of 95 mg/dL
D. Potassium level of 3.8 mEq/L
Correct ANSWER✨✨✔-: C
,Rationale for Option A: Incorrect. A creatinine level of 0.8 mg/dL is within normal range (0.6-1.2 mg/dL).
In ESRD, creatinine levels are significantly elevated, often exceeding 10 mg/dL, due to the kidneys'
inability to filter this waste product.
www.ncbi.nlm.nih.gov
Rationale for Option B: Incorrect. A GFR of 85 mL/min is normal or near-normal (normal is 90-120
mL/min). ESRD is diagnosed when GFR falls below 15 mL/min, indicating severe kidney dysfunction
requiring dialysis or transplantation.
www.kidney.org
Rationale for Option C: Correct. A BUN of 95 mg/dL is significantly elevated (normal is 7-20 mg/dL) and
consistent with ESRD. The elevated BUN reflects the accumulation of urea and other nitrogenous waste
products that the failing kidneys cannot eliminate, leading to uremia.
www.ncbi.nlm.nih.gov
Rationale for Option D: Incorrect. A potassium level of 3.8 mEq/L is within normal range (3.5-5.0 mEq/L).
While clients with ESRD are at risk for hyperkalemia, this particular value is normal and does not indicate
the severe electrolyte imbalances typically seen in ESRD.

Question 4
Which clinical manifestation would the nurse expect to assess in a client with ESRD?
A. Polyuria and polydipsia
B. Hypertension and fluid overload
C. Increased energy and alertness
D. Weight loss and dehydration
Correct ANSWER✨✨✔-: B
Rationale for Option A: Incorrect. Polyuria and polydipsia are more characteristic of diabetes mellitus or
the early stages of some kidney diseases. In ESRD, oliguria (decreased urine output) or anuria (no urine
output) is more common due to severe loss of kidney function.
www.kidney.org
Rationale for Option B: Correct. Hypertension and fluid overload are hallmark manifestations of ESRD.
The failing kidneys cannot adequately regulate fluid balance or blood pressure, leading to fluid
retention, edema, and hypertension. This occurs due to activation of the renin-angiotensin-aldosterone
system and inability to excrete excess sodium and water.
nurseslabs.com
, Rationale for Option C: Incorrect. Clients with ESRD typically experience fatigue, weakness, and
decreased alertness due to uremia, anemia, and toxin accumulation. Increased energy would be
unexpected and inconsistent with the disease process.
my.clevelandclinic.org
Rationale for Option D: Incorrect. While some clients with ESRD may experience anorexia and weight
loss from uremia, weight gain from fluid retention is more common. Dehydration is unlikely unless the
client is over-diuresed or has inadequate fluid intake, but fluid overload is the typical presentation.

Question 5
The nurse is teaching a client about the stages of chronic kidney disease (CKD). At which stage is ESRD
diagnosed?
A. Stage 2
B. Stage 3
C. Stage 4
D. Stage 5
Correct ANSWER✨✨✔-: D
Rationale for Option A: Incorrect. Stage 2 CKD is characterized by mild kidney damage with GFR of 60-89
mL/min. This is early-stage disease that does not require dialysis and is managed with lifestyle
modifications and medication.
www.kidney.org
Rationale for Option B: Incorrect. Stage 3 CKD represents moderate kidney disease with GFR of 30-59
mL/min. While significant, this stage does not yet require renal replacement therapy and is managed
conservatively.
www.kidney.org
Rationale for Option C: Incorrect. Stage 4 CKD is severe kidney disease with GFR of 15-29 mL/min.
Clients at this stage require preparation for renal replacement therapy but do not yet have ESRD.
www.kidney.org
Rationale for Option D: Correct. Stage 5 CKD, also called ESRD or kidney failure, is diagnosed when GFR
falls below 15 mL/min. At this stage, the kidneys have lost 85-90% of their function, and dialysis or
kidney transplantation is necessary for survival.
