SECTION 1: RENAL SYSTEM DISORDERS
QUESTION 1
CASE: A 28-year-old woman presents with fever, flank pain, and dysuria. Urinalysis
reveals pyuria and bacteriuria. CT scan shows inflammation extending from the
renal pelvis into the renal parenchyma.
This patient most likely has:
A. Cystitis
,B. Pyelonephritis
C. Nephrotic syndrome
D. Renal cell carcinoma
Correct Answer: B
Rationale: Pyelonephritis is an inflammation of the renal pelvis and kidney
parenchyma, most commonly caused by bacterial infection that ascends from the
lower urinary tract. The classic triad of fever, flank pain, and dysuria
distinguishes pyelonephritis from cystitis, which typically presents with
frequency, urgency, and dysuria without systemic symptoms. The CT finding of
inflammation extending into the renal parenchyma confirms upper urinary tract
involvement. Pyelonephritis can lead to renal scarring, abscess formation, and
sepsis if untreated. Common causative organisms include Escherichia coli,
Klebsiella, Proteus, and Enterococcus. Risk factors include female anatomy,
urinary stasis, vesicoureteral reflux, and immunocompromised states.
QUESTION 2
CASE: A 45-year-old patient with recurrent urinary tract infections presents with
hypertension, progressive renal dysfunction, and small scarred kidneys on imaging.
History reveals multiple episodes of acute pyelonephritis and vesicoureteral
reflux.
This patient most likely has:
A. Acute glomerulonephritis
B. Chronic pyelonephritis
C. Renal adenoma
D. Nephrotic syndrome
Correct Answer: B
Rationale: Chronic pyelonephritis is characterized by progressive interstitial
fibrosis, tubular atrophy, and chronic inflammation resulting from repeated
episodes of acute pyelonephritis. The condition is often associated with chronic
urinary tract infections, vesicoureteral reflux (reflux nephropathy), or
obstructive uropathy. Over time, the chronic inflammatory process leads to
scarring and contraction of the kidneys, resulting in small, scarred kidneys on
imaging. Progressive renal dysfunction manifests as declining glomerular
filtration rate (GFR), rising serum creatinine, and electrolyte imbalances.
Hypertension is a common complication due to activation of the renin-angiotensin-
aldosterone system from ischemic renal tissue. Unlike acute glomerulonephritis,
which primarily affects the glomeruli, chronic pyelonephritis is a tubulointerstitial
,disease that does not typically present with nephritic or nephrotic syndrome
features.
QUESTION 3
CASE: A 32-year-old woman presents with urinary frequency, urgency, and dysuria.
She has no fever, no flank pain, and no systemic symptoms. Urinalysis shows
pyuria and bacteriuria. The patient is otherwise healthy.
This patient most likely has:
A. Pyelonephritis
B. Cystitis
C. Glomerulonephritis
D. Renal cell carcinoma
Correct Answer: B
Rationale: Cystitis is an inflammation of the urinary bladder, typically caused
by bacterial infection. The classic symptoms include urinary frequency, urgency,
dysuria, suprapubic discomfort, and sometimes hematuria. Unlike pyelonephritis,
cystitis is confined to the lower urinary tract and does not produce systemic
symptoms such as fever, chills, or flank pain. The absence of fever and flank
pain in this patient, along with the presence of lower urinary tract symptoms,
strongly suggests cystitis. Common pathogens include Escherichia coli (most
common), Staphylococcus saprophyticus (common in young sexually active women),
Klebsiella, and Enterococcus. Risk factors include female anatomy (short urethra),
sexual activity, use of spermicides, and urinary catheterization. Uncomplicated
cystitis typically responds well to short-course antibiotic therapy.
QUESTION 4
A patient with cystitis asks why E. coli is the most common cause. The nurse's
BEST explanation is:
A. E. coli produces toxins that damage the bladder
B. E. coli has adhesins that allow attachment to uroepithelial cells
C. E. coli is resistant to all antibiotics
D. E. coli is the most abundant bacteria in the gut
Correct Answer: B
Rationale: Escherichia coli is the most common cause of uncomplicated urinary
tract infections because uropathogenic strains of E. coli possess specialized
adhesins, including P fimbriae and type 1 pili, which enable the bacteria to
attach firmly to the uroepithelial cells lining the bladder. This attachment is
, critical for bacterial colonization and infection because it prevents the bacteria
from being washed away by the flow of urine. Once attached, the bacteria can
multiply and ascend the urinary tract. Type 1 pili mediate adherence to mannose-
containing receptors on bladder epithelial cells, while P fimbriae bind to
globoseries glycosphingolipids on renal epithelial cells, promoting ascent to the
kidneys. Additionally, E. coli can produce toxins and evade the host immune
response. While E. coli is indeed abundant in the gastrointestinal tract, this
alone does not explain its pathogenicity in the urinary tract; the presence of
specific virulence factors is the key mechanism.
QUESTION 5
CASE: A 55-year-old man presents with painless gross hematuria, a palpable flank
mass, and unintentional weight loss of 15 pounds over the past 3 months. He is a
long-term smoker and has a history of hypertension. CT scan reveals a solid renal
mass arising from the kidney tubules.
This patient most likely has:
A. Renal adenoma
B. Renal cell carcinoma
C. Transitional cell carcinoma
D. Nephrotic syndrome
Correct Answer: B
Rationale: Renal cell carcinoma (RCC) is the most common malignant tumor of the
kidney, arising from the epithelial cells of the proximal convoluted tubules.
The classic clinical triad of hematuria, flank pain, and a palpable abdominal
mass is seen in only about 10% of patients, but when present, it is highly
suggestive of RCC. Painless gross hematuria is the most common presenting symptom
and occurs due to tumor invasion into the collecting system. RCC is strongly
associated with tobacco smoking, which is a major risk factor. Other risk factors
include obesity, hypertension, occupational exposure to cadmium and asbestos,
and end-stage renal disease. RCC tends to metastasize early via hematogenous
routes to the lungs, bone, liver, and brain. Paraneoplastic syndromes may also
occur due to ectopic hormone production, including erythropoietin (polycythemia),
parathyroid hormone-related protein (hypercalcemia), and renin (hypertension).
QUESTION 6
CASE: A 60-year-old patient has a small, slow-growing glandular noncancerous
tumor found incidentally on abdominal imaging performed for unrelated symptoms.
The tumor is well-circumscribed, measures 1.5 cm in diameter, and arises from
verified answers and detailed rationales for NSG 530 Exam 3 – Advanced
Pathophysiology at Wilkes University. Covers Renal, Fluid/Electrolyte,
Endocrine, Cardiovascular, Respiratory, and Neurological disorders. Each
question follows a test bank format with multiple-choice options, correct

pathophysiology, clinical presentation, and treatment principles. Designed to
