NURS 6501 ADVANCED PATHOPHYSIOLOGY MIDTERM
EXAM: 200 COMPREHENSIVE EXAM QUESTIONS WITH
ANSWERS AND RATIONALES
1. A patient presents with symmetric joint pain and stiffness in the
hands and wrists that has persisted for over six weeks. Which
pathophysiological process is the hallmark of this condition?
A. Degeneration of articular cartilage
B. Autoimmune-mediated chronic inflammation of the synovium
C. Deposition of monosodium urate crystals in the joints
D. Calcification of the joint capsule
Correct Answer: B
Rationale: Rheumatoid arthritis is an autoimmune disorder
characterized by chronic inflammation of the synovial membrane,
leading to pannus formation and joint destruction. Osteoarthritis is
characterized by cartilage degeneration, and gout is caused by urate
crystal deposition.
2. Which laboratory finding is most specific for confirming a diagnosis
of rheumatoid arthritis?
A. Elevated erythrocyte sedimentation rate (ESR)
B. Positive antinuclear antibody (ANA)
C. Positive anti-cyclic citrullinated peptide (anti-CCP)
D. Elevated C-reactive protein (CRP)
Correct Answer: C
Rationale: While ESR and CRP are elevated in inflammation, anti-CCP is
,highly specific for rheumatoid arthritis and can be present years before
symptom onset. ANA is more associated with systemic lupus
erythematosus.
3. A complete blood count (CBC) is ordered for a patient with fatigue.
The nurse understands that which component of the CBC is
responsible for oxygen transport?
A. White blood cells
B. Platelets
C. Hemoglobin
D. Hematocrit
Correct Answer: C
Rationale: Hemoglobin is the iron-containing protein within red blood
cells that binds and transports oxygen from the lungs to the tissues.
Hematocrit measures the percentage of blood volume occupied by red
blood cells.
4. A patient has a hematocrit (Hct) of 30%. How should the nurse
interpret this finding?
A. It indicates polycythemia.
B. It indicates anemia.
C. It is within normal limits.
D. It indicates severe dehydration.
Correct Answer: B
Rationale: Normal hematocrit is roughly 36% to 52% for men and 34%
to 46% for women, depending on the lab. A value of 30% indicates
anemia, a reduction in the percentage of red blood cells.
5. Which of the following describes the mean corpuscular volume
(MCV)?
,A. The average volume of platelets in the blood
B. The average size of a red blood cell
C. The percentage of reticulocytes in circulation
D. The concentration of hemoglobin within a single red blood cell
Correct Answer: B
Rationale: MCV stands for mean corpuscular volume, which is a
measure of the average size of red blood cells. It is used to classify
anemias as microcytic, normocytic, or macrocytic.
6. A patient presents with a platelet count of 50,000/microliter. Which
assessment finding is most concerning to the nurse?
A. Fatigue and pallor
B. Fever and chills
C. Bruising and petechiae
D. Tachycardia and hypotension
Correct Answer: C
Rationale: A normal platelet count is 150,000 to 450,000/microliter. A
count of 50,000 indicates thrombocytopenia, which significantly
increases the risk of bleeding, manifesting as bruising and petechiae.
7. An elevated white blood cell (WBC) count with a "left shift"
indicates which pathophysiological state?
A. Viral infection
B. Acute bacterial infection
C. Aplastic anemia
D. Autoimmune disease
Correct Answer: B
Rationale: A left shift means an increase in immature neutrophils
(bands) in the blood, which typically occurs during an acute bacterial
infection as the bone marrow releases stored cells to fight the infection.
, 8. What is the primary function of serum haptoglobin?
A. To transport iron in the bloodstream
B. To bind free hemoglobin released from destroyed red blood cells
C. To stimulate the production of red blood cells in the bone marrow
D. To act as an acute phase reactant during inflammation
Correct Answer: B
Rationale: Haptoglobin binds free hemoglobin in the blood to prevent
its excretion by the kidneys and to conserve iron. When hemolysis
occurs, haptoglobin levels decrease as it is consumed.
9. A patient with suspected iron deficiency anemia has serum iron
studies drawn. Which finding would the nurse expect?
A. Increased serum ferritin
B. Decreased total iron-binding capacity (TIBC)
C. Decreased serum iron concentration
D. Increased transferrin saturation
Correct Answer: C
Rationale: In iron deficiency anemia, serum iron is low because there is
insufficient iron available. TIBC is typically elevated, ferritin is
decreased, and transferrin saturation is low.
10. Which laboratory test provides the best indicator of stored iron in
the body?
A. Serum iron concentration
B. Total iron-binding capacity (TIBC)
C. Serum ferritin concentration
D. Percent saturation
Correct Answer: C
Rationale: Serum ferritin is a protein that stores iron inside cells. It is the
