Advanced Pathophysiology Questions and
Answers () (Real Exam Verified
Answers)
• Acute Renal Failure -✓✓Reversible condition where kidneys respond
to diuretic with good output, indicating functioning kidneys.
• Acute Pyelonephritis -✓✓A kidney infection characterized by bacterial
colonization, adherence and invasion, inflammation, and renal injury.
• Diagnosis of Acute Pyelonephritis -✓✓Urinalysis shows positive urine
culture with significant bacteriuria (>10^5 CFU/mL) and pyuria (≥10
white blood cells per high-power field).
• Renal Calculi -✓✓Kidney stones formed by supersaturation of urine,
nucleation of crystals, and urinary stasis.
• Assessment of Renal Calculi -✓✓Includes medical history, physical
exam for flank pain, imaging studies (CT scan, renal ultrasound, x-ray),
and lab tests.
• Treatment for Renal Calculi -✓✓Conservative treatment for stones <5
mm, medical management with thiazide diuretics or allopurinol, and
lithotripsy for stones >5 mm.
• Chronic Renal Failure -✓✓Progressive loss of renal function
associated with systemic diseases like hypertension and diabetes
mellitus.
• CKD Stage Determination -✓✓Determined by estimates of GFR and
albuminuria.
,• Flank Pain -✓✓Pain in the side of the body, often associated with
kidney issues such as renal calculi or pyelonephritis.
• CBC -✓✓Complete blood count used to evaluate white blood cell
count as an indicator of infection.
• Imaging Studies for Pyelonephritis -✓✓Renal ultrasound or CT scan
used to identify structural abnormalities and complications.
• Urinary Stasis -✓✓Condition where urine flow is inadequate, allowing
crystals to remain in the urinary tract and form stones.
• Nucleation -✓✓Process where crystals act as sites for further crystal
deposition in the formation of kidney stones.
• Systemic Signs of Severe Infection -✓✓High fever, chills, and
tachycardia may suggest a severe infection in the context of
pyelonephritis.
• Costovertebral Angle (CVA) Tenderness -✓✓Tenderness in the area of
the lower back, often assessed during physical exams for kidney-related
conditions.
• Hematuria -✓✓Presence of blood in urine, which can indicate renal
calculi or infection.
• Thiazide Diuretics -✓✓Medications used for medical management of
calcium stones in renal calculi.
• Allopurinol -✓✓Medication used for medical management of uric acid
stones in renal calculi.
, • Lithotripsy -✓✓Procedure used to remove larger kidney stones (>5
mm) causing severe symptoms.
• Goals of Treatment for Renal Calculi -✓✓Manage acute pain, promote
passage of stone, reduce size of existing stones, and prevent new stone
formation.
• Bacterial Colonization -✓✓Initial step in the pathophysiology of acute
pyelonephritis where bacteria adhere to the renal tissue.
• Inflammation and Immune Response -✓✓Body's reaction to infection
in acute pyelonephritis, leading to renal injury and complications.
• Stage 1 CKD -✓✓There is kidney damage with normal or elevated
GFR, eGFR 60-89 mL/min.
• Stage 2 CKD -✓✓There is kidney damage with mild decrease in GFR,
eGFR 90-120 mL/min.
• Complications of Stage 2 CKD -✓✓Anemia, Hypertension, Decreased
calcium absorption, Hyperlipidemia, Heart failure, Left ventricular
hypertrophy, Fluid volume overload, Hyperkalemia.
• Stage 3 CKD -✓✓There is a moderate decrease in GFR, eGFR 30-59
mL/min.
• Stage 4 CKD -✓✓There is a severe decrease in GFR, eGFR 15-29
mL/min.
• Stage 5 CKD -✓✓Kidney failure - End-stage renal disease, eGFR <15
mL/min (dialysis).
