EXAM QUESTIONS
QUESTION 1
Acute renal failure
CORRECT ANSWER
Reversible
Determining prognosis- kidneys respond to diuretic with good output; this indicates that kidneys are
functioning well
RATIONALE: In the context of acute renal failure, the kidneys' ability to respond to a diuretic with good output is a strong
indicator of their functioning well, as it suggests that the kidneys can still concentrate urine and excrete waste products,
which is a key characteristic of normal kidney function. This reversibility is a critical distinguishing factor between acute and
chronic renal failure, where the kidneys' ability to respond to diuretics is typically impaired.

, QUESTION 2
Acute Pyelonephritis
CORRECT ANSWER
Diagnosing by clinical symptoms alone can be difficult; can be similar to cystitis
Diagnosis established by:
-Urine culture
-Urinalysis (WBC casts indicates pyelonephritis, but may not always be present)
-Signs/Symptoms
-Complicated pyelonephritis requires blood cultures and urinary tract imaging
RATIONALE: Diagnosing acute pyelonephritis solely based on clinical symptoms can be challenging due to its similarity to
other conditions, such as cystitis. A comprehensive diagnosis involves a combination of urine culture, urinalysis, clinical
signs and symptoms, and in complicated cases, additional tests like blood cultures and urinary tract imaging, which provide
more accurate and reliable information to establish the diagnosis.
QUESTION 3
Renal Calculi (Renal Stones)
CORRECT ANSWER
Goals of Treatment:
Manage acute pain
Promote passage of stone
Reduce size of stone
Prevent new stone formation
RATIONALE: The goals of treatment for renal calculi are centered around addressing the immediate symptoms and
underlying causes of the condition, which involves managing acute pain caused by the stone, facilitating its passage
through the urinary tract, and preventing new stone formation through medical interventions and lifestyle modifications. By
prioritizing these objectives, healthcare providers can effectively treat renal calculi and minimize the risk of complications,
such as infection and obstruction, which can arise from the presence of a kidney stone.
QUESTION 4
Chronic Renal Failure
CORRECT ANSWER
Chronic Kidney Disease (CKD) is a progressive loss of renal function associated with systemic disease such as
hypertension, diabetes mellitus (most significant risk factor), systemic lupus erythematosus or intrinsic
kidney disease
CKD stage is determined by estimates of GFR and albuminuria
RATIONALE: This answer is correct because it specifically identifies the disease process of CKD, its associated risk factors,
and the key indicators used to determine its stage, providing a comprehensive understanding of the condition. By
explaining the underlying mechanism and diagnostic criteria of CKD, it accurately describes the concept of Chronic Renal
Failure, making it a precise and informative response.

, QUESTION 5
Who is a candidate for dialysis?
CORRECT ANSWER
End-stage renal disease (ESRD) is the final stage of CKD with the number one cause being diabetes mellitus
combined with hypertension. At this point, the patient is completely dependent on dialysis to survive.
CKD is classified into five stages and is based on the patient's GFR rather than symptoms.
Patients will need dialysis when the following symptoms are present:
--Metabolic acidosis.
--Hyperkalemia: Hyperkalemia in the presence of EKG changes (peaked T-waves) is an indication for dialysis.
--Hyperkalemia by itself is not an indication for dialysis.
--Drug toxicity: Drug toxicity due to the following drugs is an indication for dialysis and include salicylates,
Lithium, Isopropanol, Methanol and Ethylene glycol).
--Fluid volume overload that is not responsive to diuretics.
--Uremic symptoms due to nitrogenous wastes in the blood stream.
RATIONALE: The correct answer identifies the specific symptoms that necessitate dialysis, as these conditions indicate an
extreme decline in kidney function, rendering the kidneys unable to maintain proper chemical balance, fluid balance, and
waste removal on their own. By highlighting these symptoms, the answer emphasizes that dialysis is only required when
the kidneys have reached a critical point, where conservative management is no longer sufficient to prevent life-threatening
complications.
QUESTION 6
Stage I CKD
CORRECT ANSWER
There is kidney damage with normal or elevated GFR
90-120
RATIONALE: Stage I Chronic Kidney Disease (CKD) is defined by kidney damage with normal or elevated Glomerular
Filtration Rate (GFR), which indicates that while kidney function appears to be normal, there is underlying damage that can
progress to more severe kidney disease. This stage is characterized by the presence of kidney damage, such as proteinuria
or hematuria, rather than a decline in kidney function, which is reflected by a normal or elevated GFR within the 90-120
range.

, QUESTION 7
Stage II CKD
CORRECT ANSWER
There is kidney damage with mild decrease in GFR
60-89
RATIONALE: The statement "There is kidney damage with mild decrease in GFR 60-89" is considered Stage II CKD because
it indicates the presence of kidney damage, which is a hallmark of chronic kidney disease, and a mild decrease in
glomerular filtration rate (GFR) between 60-89, which signifies a slight reduction in kidney function. This combination of
kidney damage and mild GFR reduction places the individual in the early stages of CKD, specifically Stage II, which is
characterized by a mild impairment in kidney function.
QUESTION 8
Stage III CKD
CORRECT ANSWER
There is a moderate decrease in GFR
30-59
RATIONALE: Stage III CKD is characterized by a moderate loss of kidney function, specifically a glomerular filtration rate
(GFR) between 30-59, indicating a significant decline in kidney function but still some remaining function. This classification
is based on the Kidney Disease Outcomes Quality Initiative (KDOQI) guidelines, which categorize CKD stages based on GFR
levels to provide a standardized framework for diagnosis and treatment.
QUESTION 9
Stage IV CKD
CORRECT ANSWER
There is a severe decrease in GFR
15-29
RATIONALE: The correct answer is based on the classification of Chronic Kidney Disease (CKD) stages, where a severe
decrease in Glomerular Filtration Rate (GFR), specifically a GFR of 15-29, falls under Stage IV CKD because it indicates
significant kidney impairment and damage. This stage is characterized by a high risk of complications, including
cardiovascular disease and kidney failure, necessitating closer monitoring and medical intervention.
