NR507 FINAL EXAM: ADVANCED
PATHOPHYSIOLOGY EXAM
QUESTIONS AND ANSWERS 2026
1. Which characteristic is a hallmark of Nephrotic Syndrome?
A. Gross hematuria and hypertension
B. Decreased glomerular permeability to proteins
C. Massive proteinuria (>3.5g/day) and hypoalbuminemia
D. Rapidly progressive renal failure with crescent formation
Answer: C
Conceptual Explanation: Nephrotic syndrome is defined by massive proteinuria,
hypoalbuminemia, hyperlipidemia, and edema due to increased glomerular permeability.
2. In the Somogyi effect, what is the primary physiological response to nocturnal
hypoglycemia?
A. Excessive insulin production by the pancreas
B. Reduced hepatic glucose output during the early morning hours
C. Release of counter-regulatory hormones causing rebound hyperglycemia
D. Decreased sensitivity of insulin receptors at the cellular level
,Answer: C
Conceptual Explanation: The Somogyi effect involves rebound hyperglycemia in the
morning caused by the release of counter-regulatory hormones like cortisol and
epinephrine following a hypoglycemic episode at night.
3. Which pathophysiological mechanism underlies the development of Type 1 Diabetes
Mellitus?
A. Insulin resistance in peripheral tissues
B. Autoimmune destruction of pancreatic beta cells
C. Excessive glucagon secretion from alpha cells
D. Down-regulation of glucose transporter (GLUT-4) proteins
Answer: B
Conceptual Explanation: Type 1 Diabetes is primarily caused by T-cell mediated
autoimmune destruction of the beta cells in the islets of Langerhans.
4. What is the most common cause of Chronic Kidney Disease (CKD) in the United States?
A. Polycystic Kidney Disease
B. Chronic Pyelonephritis
C. Systemic Lupus Erythematosus
D. Diabetes Mellitus
Answer: D
, Conceptual Explanation: Diabetes Mellitus is the leading cause of CKD, followed closely by
hypertension.
5. In Heart Failure with Preserved Ejection Fraction (HFpEF), the primary problem is:
A. Impaired ventricular filling due to stiff non-compliant muscle
B. Loss of myocardial contractility
C. Dilation of the left ventricle
D. Reduction in stroke volume despite normal filling pressures
Answer: A
Conceptual Explanation: HFpEF (Diastolic Heart Failure) is characterized by impaired
relaxation and increased stiffness of the ventricle, hindering proper filling despite normal
ejection fractions.
6. Which hormone is inappropriately elevated in Syndrome of Inappropriate Antidiuretic
Hormone (SIADH)?
A. Aldosterone
B. Vasopressin
C. Renin
D. Oxytocin
Answer: B
