NRNP 6501: Advanced Pathophysiology FINAL Exam
Questions and Correct Answers (Verified Answers)
Plus Rationales 2025
This exam covers major organ systems, pathophysiological mechanisms, and disease
progression processes.
1. Which of the following best describes the pathophysiology of Type 1
Diabetes Mellitus?
A. Insulin resistance in peripheral tissues
B. Autoimmune destruction of pancreatic beta cells
C. Overproduction of insulin by the pancreas
D. Impaired glucose uptake due to glucagon deficiency
Type 1 diabetes is caused by autoimmune destruction of insulin-
producing beta cells in the pancreas.
2. What is the hallmark characteristic of asthma?
A. Reversible airway obstruction
B. Alveolar destruction
C. Chronic bacterial infection
D. Progressive fibrosis
Asthma is marked by inflammation and reversible obstruction of
the airways.
3. Which neurotransmitter is primarily deficient in Parkinson’s disease?
A. Dopamine
B. Serotonin
C. Acetylcholine
, D. Norepinephrine
Parkinson’s disease is associated with dopamine depletion in the
substantia nigra.
4. In left-sided heart failure, which symptom is most prominent?
A. Pulmonary congestion
B. Peripheral edema
C. Hepatomegaly
D. Jugular vein distension
Left-sided failure leads to backup of blood into the lungs, causing
pulmonary congestion.
5. What is the pathophysiological basis of emphysema?
A. Mucus hypersecretion
B. Reversible bronchospasm
C. Destruction of alveolar walls
D. Fluid accumulation in alveoli
Emphysema is characterized by destruction of alveolar walls
leading to reduced surface area for gas exchange.
6. Which hormone regulates the reabsorption of water in the distal
nephron?
A. Aldosterone
B. Antidiuretic hormone (ADH)
C. Cortisol
D. Renin
ADH increases water reabsorption in the collecting ducts of the
nephron.
, 7. Which type of hypersensitivity reaction is involved in anaphylaxis?
A. Type II
B. Type I
C. Type III
D. Type IV
Type I hypersensitivity involves IgE-mediated allergic reactions like
anaphylaxis.
8. Which lab finding is most consistent with iron deficiency anemia?
A. Elevated ferritin
B. Macrocytic red cells
C. Microcytic hypochromic red cells
D. High MCHC
Iron deficiency results in small (microcytic), pale (hypochromic) red
blood cells.
9. What initiates the intrinsic coagulation pathway?
A. Endothelial damage
B. Tissue factor release
C. Thromboplastin
D. Platelet plug formation
Intrinsic pathway is initiated by damage to the blood vessel’s
endothelium.
10. Which of the following contributes to the development of
atherosclerosis?
A. Low LDL
B. Endothelial injury and inflammation
C. Increased HDL
