1. A 58-year-old patient with acute renal failure is responding well to
diuretic therapy with good urine output. What does this indicate
regarding the patient's prognosis?
A) The kidneys are not functioning at all
B) The kidneys are functioning well and prognosis is favorable
C) The patient will require immediate dialysis
D) The patient has end-stage renal disease
Answer: B) The kidneys are functioning well and prognosis is favorable
Determining prognosis in acute renal failure involves assessing whether
the kidneys respond to diuretic therapy with good output, which
indicates that the kidneys are functioning well and the patient has a
favorable prognosis for recovery.
2. A 45-year-old patient presents with fever, flank pain, and dysuria.
Urinalysis reveals WBC casts. What is the most likely diagnosis?
A) Cystitis
B) Acute pyelonephritis
C) Renal calculi
D) Glomerulonephritis
Answer: B) Acute pyelonephritis
The presence of WBC casts on urinalysis indicates pyelonephritis, as
WBC casts are formed in the renal tubules and their presence confirms
renal parenchymal involvement rather than just lower urinary tract
infection.

3. A 62-year-old patient with diabetes mellitus and hypertension is
diagnosed with Stage III CKD. What is the GFR range for Stage III
CKD?
A) 90-120 mL/min
B) 60-89 mL/min
C) 30-59 mL/min
D) 15-29 mL/min
Answer: C) 30-59 mL/min
Stage III CKD is defined by a moderate decrease in GFR between 30-59
mL/min, representing significant kidney damage with declining function
that requires careful monitoring and management.
4. A 55-year-old patient with Stage IV CKD asks about the
progression of their disease. What should the healthcare provider
tell them about progression from Stage IV to Stage V?
A) Progression is unlikely with proper treatment
B) Progression to Stage V is inevitable
C) Progression can be completely halted
D) Progression only occurs in patients with diabetes
Answer: B) Progression to Stage V is inevitable
Once Stage IV CKD (GFR 15-29 mL/min) is reached, progression to
Stage V is inevitable, and the patient will eventually require dialysis or
kidney transplant for survival.
5. A 50-year-old patient with ESRD presents with peaked T-waves
on EKG and hyperkalemia. What is the appropriate intervention?
A) Oral potassium supplements
B) Immediate dialysis
C) Dietary potassium restriction only
D) Loop diuretics
Answer: B) Immediate dialysis
,3
Hyperkalemia in the presence of EKG changes such as peaked T-waves
is an indication for dialysis, as this represents a life-threatening cardiac
emergency requiring immediate intervention to lower potassium levels.
6. A 48-year-old patient with CKD presents with metabolic acidosis,
fluid volume overload unresponsive to diuretics, and uremic
symptoms. What is the most appropriate treatment?
A) Increased diuretic therapy
B) Dietary modifications
C) Initiation of dialysis
D) Fluid restriction only
Answer: C) Initiation of dialysis
Patients will need dialysis when they present with metabolic acidosis,
fluid volume overload not responsive to diuretics, uremic symptoms due
to nitrogenous wastes, hyperkalemia with EKG changes, or drug toxicity
from certain medications.
7. A 65-year-old patient is diagnosed with CKD. What is the most
significant risk factor for developing CKD?
A) Hyperlipidemia
B) Diabetes mellitus
C) Obesity
D) Smoking
Answer: B) Diabetes mellitus
Diabetes mellitus is the most significant risk factor for chronic kidney
disease, often combined with hypertension, and is the number one cause
of end-stage renal disease requiring dialysis.
8. A 60-year-old patient with CKD is found to have decreased
calcium absorption. What complication of decreased GFR does this
, 4
represent?
A) Anemia
B) Hyperlipidemia
C) Decreased calcium absorption
D) Metabolic acidosis
Answer: C) Decreased calcium absorption
Decreased GFR in CKD leads to multiple complications including
decreased calcium absorption due to impaired vitamin D activation and
resulting hypocalcemia, which can contribute to bone disease and other
metabolic disturbances.
9. A 52-year-old patient presents with symptoms of GERD including
dysphagia and weight loss. What is the significance of these warning
signs?
A) These are normal symptoms of GERD
B) These symptoms indicate the need for immediate endoscopy
C) These symptoms will resolve with antacids
D) These symptoms indicate mild GERD
Answer: B) These symptoms indicate the need for immediate endoscopy
GERD warning signs include symptoms over age 50 such as dysphagia,
odynophagia, nausea and vomiting, weight loss, melena, and early
satiety, which warrant immediate endoscopic evaluation to rule out
malignancy.
10. A 68-year-old patient with a sliding hiatal hernia asks about
treatment options. What is the recommended conservative
treatment for this condition?
A) Surgical repair
B) Eating small, frequent meals and avoiding recumbent position after
eating
C) High-fiber diet
